INTRODUCTION SW205T A High Performance Medium Twin Helicopter


SOUTHWEST FLORIDA AVIATION, INC. is an enterprise dedicated to the development of efficient and cost-effective helicopters. The company draws on the many years of experience of its designers, engineers and production staff for each of its projects. SWFA is capable of producing, testing, manufacturing and supporting all of its helicopters anywhere in the world. For the SW205T project, SOUTHWEST FLORIDA
AVIATION, INC has entered into a sales and marketing agreement with Zeeland Aviation Corporation to promote and sell the SW205T Helicopters.

Executive Summary

The SW205T is based on the 205 series and it’s counterpart, the UH-1H military version. More than 10,000 of the UH-1 helicopters have been manufactured since it’s introduction as it proved itself to be both reliable and efficient. The SW205T takes an greatly modified and enhanced version of the UH-1H aircraft into the 21st Century where it will operate more efficiently, safely and at lower cost than ever before. Equipped with two Honeywell T53-L-13B engines, the SW205T will outperform most comparable medium twin helicopters, and do so at a much lower initial acquisition cost as well as lower operating costs.

During conversion of the basic UH-1H/205 to the SW205T configuration the airframe is completely refurbished, with all major and minor components installed in either a new or overhauled condition. Additionally, the single engine is replaced by two T53-L-13B engines and an upgraded transmission providing higher speeds with longer range and lift capabilities. As a result of these upgrades the time between overhaul (TBO) for all major drive system components has been greatly extended. When the time between scheduled maintenance intervals is increased, the cost for maintenance decreases, as will overall operational cost per flight hour due to the increased aircraft availability. A variety of other upgrades as described later can be accomplished to specifically tailor each helicopter to the requirements of the operator.


Upgrade Overview
UH-1/205 Upgrades that are included when producing the SW205T include the following items which are standard to all aircraft of this model:

  • 212 Style Nose provides better flight characteristics and additional space for avionics
  • Twin engines provide greater performance capabilities
  • K-Flex Drive Shafts provide longer service life with higher reliabilities
  • 412 transmission to support increased power at takeoff (1370 SHP) and continuous (1190 SHP)
  • 212 Tail Rotor Hub Assembly provides 50% more tail rotor authority
  • 212 Style Rotor Blades are wider and more efficient while providing higher performance (Option for Composite Blades)
  • 412 90° and 42° Gear Boxes and Drive Shafts provide higher performance as well as longer time between overhaul requirements
  • 212 Style Tail Boom (Incorporates tail boom baggage compartment as an option).
  • High landing cross tubes provides more clearance when landing in undeveloped areas

Performance and Maintenance Upgrades Overview

The following performance and maintenance upgrades will be incorporated in the SW205T Helicopter:

  • Electrical Wiring Updates and Power Module installation in Nose
  • Engine Lube System Modification including an additional oil cooler blow as well as a heavy duty engine oil cooler
  • Main Transmission Lube System Modification including additional oil jets installed for additional input quill
  • 90° Gearbox Modification to 412 style to provide more tail rotor authority
  • 42° Gearbox Modification to 412 style for increased safety


The SW205T has several important power system upgrades which are described below

Twin Engine Installation

The engines are placed on the transmission deck at opposing sides of the transmission, exactly 180 degrees from each other. Each engine feeds power to the transmission via a separate driveshaft. This installation eliminates the need for a combining gearbox, thus reducing weight, cost, and complexity in the power train as well saving fuel. Jamie Hill holds the U.S. patent for this dual engine installation. Where most dual engine helicopters will not perform well on one engine, the SW205T will suffer no loss of performance on one engine. This will also allow the aircraft to have a major surplus of reserve power available. This will also increase the hot weather and the high altitude

By having this excess of power available, the engines are not tapped out on torque or exhaust gas temperatures. This means that the engines can operate at a lower temperature internally, which in turn means less wear or damage to the nozzles or turbines. Additionally, by having this reserve power available, the pilot can either reduce the power of one engine to ground or flight idle or turn it off for long duration flights. The aircraft would not suffer any performance loss in this case and reduce fuel consumption. The cabin shall be modified as part of the dual engine support structure upgrade and Space Doors shall be installed. This modification shall result in an approximately eight additional cubic feet being made available.

Cabin will be modified by performing the following:

  • Engine area is 30 inches wide extending forward off the face of the transmission pylon area;
  • The passenger seating in front of the transmission pylon is relocated.
  • Seating capacity remains the same;
  • Construction is of FAA aviation quality.


Having the input of both engines at 180 degrees to each other reduces the stresses placed on the transmission. As this configuration has only one transmission input quill per engine and the input torque is 180 degrees apart, there is significant wear reduction to the internal parts of the transmission (Reference Figure 4). As a result the transmission will have a much higher Time Between Overhaul requirement of 6,000 hours.

The major upgrades will be in the Transmission area with the pylon area and landing gear mounts being reinforced. The transmission will be upgraded to the 212, UH-1W, 214 or 412 configuration depending on engines installed. The tail boom mounts will be upgraded to handle the additional toque available. After installation of a vibration monitor and an oil debris monitor, the transmission would be “On Condition” to determine TBO. The same arrangement can be installed to monitor the engine and drive train components, thus reducing maintenance costs and improving flight safety.


Cockpit Instrument Panel

  • The standard instrument panel will be modified to provide the following instrumentation supporting the dual engines.
  • Triple Tachometer – 1 each
  • Oil Temperature Gauge – 2 Each
  • Oil Pressure Gauge – 2 Each
  • NI Gauge – 2 Each
  • EGT Gauge – 2 Each
  • Torque Gauges – 2 Each


SW205T Performance Characteristics.

The SW205T is an advanced version of the famous Huey helicopter which is a veteran of 50 years of service and remains in active service with the USMC as the UH-1Y Venom and AH-1Z Super Cobra. The basic design has been proven over the years.

We take this fine helicopter into a whole new era of accomplishment and capabilities by adding a second engine, beefing up many of the major components, increasing the maximum gross weight, adding lifting capacity while giving it a much longer range. All of this makes the SW205T a much more versatile machine capable of better service to the operator over a greatly extended spectrum of operational requirements. SW205T performance characteristics are compared in Table 2 below

The SW205T clearly outperforms any comparable medium helicopters available today, and does so at an initial cost of less than half of the competing helicopters while providing operators an operating cost that is much less than either recently designed helicopters of legacy Huey’s. This is possible due to advanced design and engineering techniques which incorporate the most recent technical advances into a highly successful marriage with the proven airframe and power plants of the Huey series of helicopters.

Figures provided in the Performance Comparison Chart (Table 2 below) are for the standard SW205T. Subsequent versions will incorporate short “wings” to increase the top speed and offload the rotor system. Supplemental fuel tanks will also be mounted, either internally or external on the wings to greatly increase the range for CSAR/SAR missions or other special long range mission requirements.

Given the additional power available with a second engine, the maximum gross weight will be increased incrementally in subsequent SW205T models as other modifications are accomplished to support the additional power. This translates into greater lifting capacity and an expanded operational envelope for high and hot environments. In the future, compliance with SWFA Technical Bulletins will increase gross weight to 18,000 lbs



The SW205T, is a very advanced version of the venerable and tested 205/UH-1H family of medium helicopters. Its capabilities far outreach any previous version of this famous line of excellent helicopters.

By mounting a second engine the helicopter now has more power which allows a much larger operational envelope and greatly expands its capabilities, regardless of operating conditions. The engines operate separately from each other entirely, and each are capable of powering the helicopter individually in any flight regime. This is an important safety of flight consideration.

The operating costs of the SW205T are substantially less than the legacy 205/UH-1H due to the use of components with longer times between overhaul, and with less stress and strain on the engines. The use of advanced technology in the redesign of certain aspects of the helicopter allows simplified solutions for the power train and flight control systems.

By using tested and proven off the shelf components in an innovative way, the SW205T is an inexpensive yet highly effective medium helicopter that has no rival in terms of cost-effectiveness among the current crop of modern medium helicopters.

In performance, the SW205T greatly outperforms the legacy 205/UH-1H, as well as the follow-on 212/412 models. It will out lift any of these helicopters throughout the operational envelope, with a longer range, and is more versatile in its capabilities. It can be outfitted for many different missions depending on the range of accessories and options selected.

A product of innovative and highly competent technical expertise, the SW205T is a helicopter for the 21st Century.

The Lynx NGT-9000 offers flexibility to display traffic on the unit itself, as well as other panel mounted avionics that use the popular ARINC 429, RS-232 or RS-422 protocols. The NGT-9000 model features an option for an in-line WiFi transmitter, enabling pilots to view ADS-B traffic on their PED (iPad) using a compatible app. Since the Lynx NGT-9000 receives simultaneously on both 1090Mhz and 978Mhz, pilots will receive ADS-B traffic regardless of altitude or geographic location.

While ADS-B traffic is comprehensive, there are limitations to the service including line of sight to station, non-equipped areas, GPS signal integrity and non-participating aircraft. The Lynx NGT-9000 has the option to be equipped with the L-3 NextGen Active Traffic® system. This enablement blends ADS-B with active traffic data, providing an uninterrupted display of aircraft equipped with Mode A, C and S transponders. Adding NextGen Active Traffic also enables extended aural alerting of intruder aircraft position such as “Traffic, 1 O’clock High, 2 Miles.” Existing SkyWatch® owners can opt to re-use the system’s antenna and cables. The L-3 NextGen Active Traffic enablement is built into the NGT-9000+, eliminating the need for an external box, saving weight and installation costs.

The Lynx NGT-9000 includes subscription-free weather data such as METARs, AIRMETs, SIGMETs and NEXRAD information overlaid on a moving map. A second map page shows Winds and Temps Aloft data. This arrangement allows the pilot to quickly page through graphical weather screens, viewing large amounts of data without overloading a single page. A touch of the finger on the graphical weather map brings up corresponding textual data of the highlighted station or weather icon. A settings page allows the pilot to further customize the weather data pages in both detail and range.

With the Lynx family of ADS-B products, you will receive up to the minute broadcast information regarding airports, Notice to Airmen (NOTAMs) and Temporary Flight Restrictions (TFR) in graphical and textual form. Similar to the weather map, touching an airport or zone icon on the graphical side of NGT-9000 map brings up its corresponding textual data. This data is useful in all phases of flight, aiding the pilot in planning proper routes and informing them about their departing and destination airports.

Honeywell's Enhanced Ground Proximity Warning Systems (EGPWS): The state-of-the-art MK XXII EGPWS is a full-featured HTAWS system with highly advanced safety functions for IFR-equipped helicopters with a radio altimeter. This system exceeds the FAA TSO-C194 requirements. In addition to HTAWS required modes, it includes several GPWS modes and unique callouts for excessive bank angle, tail strike protection, and autorotation.


Helicopter Emergency Egress Lighting Systems (HEELS) identifies emergency escape hatches, exits and push-out windows by illuminating their perimeter to guide you to safety during emergency situations.

Automatic illumination occurs if aircraft power is lost or when the lighting system water sensor becomes immersed in water. HEELS can also be manually illuminated using a three mode ON, OFF, ARMED cockpit switch. HEELS is also a battery-operated independent lighting system. A typical HEELS installation consists of an array of light emitting diodes on substrate placed around escape hatches or doors. The system has two water sensors, each of which will activate lighting upon immersion. An optional aircraft Permanent Magnet Generator (PMG) interface unit monitors rotor rpm and interfaces the HEELS to the aircraft. The system is activated upon signal loss. When the rotors fall below a threshold rpm, the HEELS will automatically illuminate. The Control Unit consists of an electronic module with a removable battery pack, which automatically recharges during flight.



The Helicopter Vibration Monitor (HVM) Kit and Altair Engine Trend Monitor System provide drive train health and engine monitoring to improve aircraft serviceability and maintainability between regularly scheduled inspections and overhaul periods. A control head located in the pedestal provides the primary flight crew interface to the HVM. A pedestal mounted USB port allows the flight crew to transfer data between the aircraft and a PC-based ground support station. An Ethernet connection provides means for maintenance personnel to connect to the ground support station. HVM diagnostics facilitate vibration- related maintenance functions such as main rotor track and balance, tail rotor balancing, main input drive shaft balancing and turning of the instrument panel Frahm absorber. Enhanced vibration diagnostics allow maintenance personnel to detect faults within the main rotor system, tail rotor drive system, engine accessory gearbox and combining gearbox. Built-in test features simplify system troubleshooting.


The HUMS Kit provides the Helicopter a comprehensive airframe, rotor, engine and drive system vibration monitoring capability, and aircraft data recording supports customer flight data monitoring (FDM) programs. The HUMS Kit is designed to conduct routine vibration management functions, with no changes required in the mandatory maintenance functions of the Maintenance Manual. The system utilizes its vibration monitoring capability to make discretionary rotor and balance adjustments. No pilot interface is required during flight operations. Data downloads are manually commanded by pressing the LED array switch located on the PBA panel in the center pedestal.

Some Rotorcraft utilizes the Honeywell SPZ-7600 digital Automatic Flight Control System (AFCS), providing 3-axis or 4-axis flight director capability. The rotorcraft can be equipped readily allowing upgrade to 4-axis which provides the additional features of yaw trim, altitude pre-select, simultaneous vertical and speed coupling, automatically decelerating approaches, radar altitude hover hold, and hover velocity assist.


The Cockpit Voice and Flight Data Recorder (CV/FDR) is an “on-condition,” line-replaceable unit that simultaneously records both cockpit voice and flight data. This CV/FDR is capable of recording a minimum of 25 hours of flight data and two hours of audio. Audio inputs are provided from three separate channels. The CVR simultaneously records all three channels, converts the audio into a digital format and stores the data in solid-state memory. Flight data is recorded in flash memory and segregated from the cockpit voice data. Flight data may be downloaded to ground station equipment in approximately five minutes. A ground support equipment interface connector is provided and easily accessible. A pedestal mounted cockpit control unit enables CV/FDR test and recorded audio monitoring. The recorder is JAR-OPS 3 approved.

Installation requires additional specialized test equipment (which is NOT included in this kit) in order to comply with the installation requirements. This equipment can either be purchased or leased.



With its advanced solid-state transmitter design eliminating the need for life limited magnetron tubes, the GWX 70 — and GWX 70H that's been made more rugged for helicopter operations — comprises the very latest and most reliable technology in onboard weather radar.

  • Scan with Doppler Accuracy
    Bringing full-color storm cell tracking to your compatible Garmin multifunction display, this Doppler-capable weather avoidance tool combines excellent range and adjustable scanning profiles with precision target definition — for accurate, easy-to-interpret, weather analysis in the cockpit. With pilot-adjustable horizontal scan angles of up to 120°, you can easily focus scanning on the areas you want to watch, while vertical scanning lets you focus on storm tops, gradients and cell buildup at various altitudes. Plus, Weather Attenuated Color Highlight (WATCH™) can identify areas beyond the radar's capability that may contain even more hazardous areas of precipitation.
  • Reduce Pilot Workload
    On compatible displays, altitude compensated tilt in the GWX 70 reduces your workload by needing to manually adjust the radar’s tilt; simply set it once to the tilt angle you want, and it will automatically adjust with any change in altitude. Also, when interfaced with your aircraft’s analog gyro or AHRS system, the GWX 70 offers full radar stabilization to 30 degrees of pitch and roll. The GWX 70 also has a ground mapping mode that can assist in a number of applications -- including navigation. Ground mapping mode provides a real-time depiction of the terrain below you.
  • Experience Solid-State Reliability
    With its digital design, the GWX 70 provides reduced power consumption and extended life when compared to previous generations of magnetron-based radars. While magnetron tubes degrade or burn out over time, the solid-state technology in the GWX 70 maintains a consistent weather picture its entire lifecycle – all while only using 40 W of power. What’s more, the all-in-one antenna/receiver/transmitter unit is available in 10", 12" and 18" radomes, so it easily installed on a wide variety of aircraft configurations.
  • Upgrade to Advanced Features
    The GWX 70 you buy today is prepared for the technologies you might need tomorrow. You can unlock a wealth of new functionality in your GWX 70, such as ground clutter suppression*, which identifies radar ground returns and removes them from the display – taking the guesswork out of interpreting what's on your screen. And optional turbulence detection* can determine areas of turbulence that might contain particulate, like rain or hail. These capabilities are available through simple software upgrades, eliminating the need to purchase new hardware in the future.

ART 2100 Avionic Upgrade
Setting a new standard in value and performance, the RDR 2100 Digital Weather Radar provides a vertical picture of a pilot-selected cross- section of the storm, offering the best view available to general aviation. The simple press of a button allows you to analyze a storm segment vertically, giving you the information you need to determine the scope of the storm.

You can examine the angle of the cell's leading edge to determine direction of movement, monitor the tops of cells to see how quickly a storm is building, and easily distinguish between ground and weather returns. The system is fully stabilized to +/- 30° combined pitch and roll, and antenna stabilization keeps your screen clear of ground returns during moderate aircraft maneuvers. You can choose between two antennas, a 10-inch or 12-inch, to fit a wide variety of airframe applications.

The RDR 2100 uses intuitive colors (green, yellow, red, magenta), and six ranges (10 nm to 320 nm) to depict the weather intensity, creating a clear picture of the weather and making it easy for you to avoid danger. The horizontal scan provides an angle of 120°; the vertical scan an angle of 60°. Using Sensitivity Time Logic, the system can correlate target distance with intensity, and its attenuation compensation reduces shadowing.

The system is fully Electronic Flight Instrument System (EFIS) compatible using ARINC 429 and ARINC 453 data busses. It also features a Multi- Function Display (MFD) interface, fault annunciation, TILT readout on display, and independent dual indicator operation.

Augmented Tail Rotor System

The conceptual design system uses a fan inside the tailboom to build a high volume of low-pressure air, which exits through slots and creates a flow of air along the tailboom utilizing the Coanda effect. This system augments the existing conventional tail rotor. The boundary layer changes the direction of airflow around the tailboom, creating thrust opposite the motion imparted to the fuselage by the torque effect of the main rotor. Augmented directional yaw control is gained through a vented drum at the end of the tailboom by the direct jet thruster. The system offers quiet and safe operation.

The anti-torque fan being considered is an axial fan with thirteen variable pitch blades. The fan provides anti-torque by furnishing variable flow of low pressure high volume air through the tailboom and thrusters. The fan operational rpm in flight at 100% power is 5,412 rpm. At 104% power, the fan rpm is 5,628.

Design Parameters:

  • Fan Rotation Direction-Top blade afterward (TBA) direction makes the inflow dynamic pressure distribution uniform, so that aerodynamic and acoustic attributes are better.
  • Blade Diameter- If large, low required power and high control power. If small, low weight and low hub drag. Diameter of the existing fan ranges 0.7m to 1.37m
  • Fan Tip Speed- In forward flight, blade is unloading. Fin makes most of the anti-torque force. Advancing side problem is not critical. Around the main rotor tip speed is usually employed.
  • Solidity-Ct/σmax and maximum thrust required determine a solidity. Range 0.5 to 0.56.
  • Number of Blades-Aspect ratio is a main parameter. Even number is better for uneven blade spacing because of dynamics. Blades number ranges 8 to 12
