Design and features of AW109 light helicopter
AW109 Power features an airframe made of lightweight aluminium alloys. It is fitted with four blade main rotor and long tail boom with two blade tail rotor. Tricycle landing gear with energy absorbing struts allows safe landing on rough terrains.
The helicopter has a length of 13.4m, a width of 7.8m and a maximum height of 3.5m. The main and tail rotor diameters are 11m and 1.94m respectively.
The helicopter is operated by one or two pilots and accommodates up to seven passengers. The cockpit is fitted with pilot / co-pilot doors and windows with sliders. The cabin has two large sliding doors and double-layer acrylic windows.
With a volume of 3.5m³, the wide cabin can be easily configured to meet various mission equipment. The spacious baggage compartment can be extended up to 2.3m to house mission-specific loads.
The interior is installed with soundproofing, bleed air heater and air conditioning to facilitate comfortable seating for occupants.
AW109 Power can be optionally fitted with a rescue hoist, cargo hook, engine air particle separator, external loudspeakers, pulsed chip detectors, rappelling hooks, retractable light, and Bambi bucket.
Cockpit and avionics
The platform offers high controllability and manoeuvrability when undertaking missions in the most demanding weather and environmental conditions.
The digital, glass and NVG-compatible cockpit is equipped with six liquid crystal instrument displays to provide the aircrew with navigational and flight information, as well as enhanced situational awareness both during the day and at night.
Avionics include three-axis duplex automatic flight control system (AFCS), radar altimeter, weather radar, global positioning system (GPS), moving map, instrument flight rules (IFR), navigation and communication systems, gyrocompass and transponder.
It also includes tactical radios, forward looking infrared radar (FLIR) / low-light television (LLTV) camera, automatic direction finder (ADF), stormscope, emergency locator transmitter (ELT), and cockpit voice and flight data recorder.
The AW109 Power attack version is armed with .50 calibre machine guns and unguided rockets for close air support and surveillance operations.
The light helicopter's safety features include emergency flotation, dual hydraulic boost and wire strike protection systems, snow skis kit / slump protection pads kit, fire extinguishers, a fully separated fuel system, reinforced windshield, rotor brake, and dual electrical systems.
Redundant lubrication and cooling systems are provided for main transmission and engines. Vibration dampers are also fitted to minimise vibration levels.
Engine and performance of AW109 Power helicopter
The AW109 Power helicopter is powered by two Pratt & Whitney Canada PW206C engines, controlled by full authority digital engine control (FADEC) system, or two Turbomeca Arrius 2K1 engines.
PW206C has a take-off power of 477kW, whereas the Arrius 2K1 has a take-off power of 500kW.
