Bell 407GXP design
Airbus Helicopters presented its new H160 medium-class rotorcraft at the Heli Expo tradeshow in Orlando, Florida, US, in March 2015.
The Bell 407GXP is a high-power derivative of the Bell 407GX. The improved helicopter incorporates a new engine and offers more payload capacity than its predecessor.
The fuselage constitutes forward, mid and tailboom sections. The forward fuselage is constructed of aluminium honeycomb and carbon graphite, while the semi-monocoque mid-structure is formed of stringers and carbon fibre composite side skins. The tailboom is a monocoque structure made of aluminium alloy.
The fuselage incorporates a four-bladed main rotor and a two-bladed teetering tail rotor. It is also fitted with a tubular skid-type landing gear with replaceable skid shoes.
The helicopter has an overall length of 12.61m, rotor diameter of 10.66m, and height of 3.10m with standard low-skid landing gear. Its maximum gross weight with external load is 2,722kg, and the maximum useful load carrying capacity is 1,160kg.
Flight deck and avionics
Garmin G1000H integrated avionics suite aboard the helicopter features a primary flight display (PFD) and a multi-function display (MFD). The twin 10.4in high-resolution LCD screens present critical flight data in an easy-to-scan layout.
The avionics suite also incorporates a helicopter terrain avoidance warning system (HTAWS), Garmin HSVT (helicopter synthetic vision technology), traffic information system (TIS), moving map, fuel flow indication and range ring, power situation indicator, and Garmin 3D audio and automatic speech recognition for controlling COM / NAV, and cabin radios.
The navigation and communications are supported by a GPS/WAAS receiver, VHF COM Transceiver and VHF NAV and Glideslope receivers. The helicopter can be fitted with Bell 2-axis autopilot stability and control augmentation system (SCAS).
Cabin features of the Bell utility helicopter
The spacious interior of the helicopter accommodates two crew members and five passengers in standard configuration. The standard cabin seating constitutes three equal-width forward facing seats at rear and two individual, rearward facing seats behind the cockpit.
Seating layout in corporate configuration includes five club-passenger seats with seat belts and single strap shoulder harness system. The helicopter can seat up to six passengers with one pilot onboard.
The cabin’s modular design also allows for easy configuration, with specialised equipment for medical and parapublic missions. The large doors allow for quick ingress and egress of passengers/equipment during emergency medical and utility missions.
The large grey-tinted plexiglass windows of the cabin offer outstanding field-of-view and high visibility for the occupants. The low vibration and noise levels further ensure a comfortable flight.
Engine and performance of Bell 407GXP
The helicopter is powered by a Rolls Royce 250-C47B/8 turbine engine equipped with a full authority digital electronic control (FADEC) system. The engine develops a maximum take-off power of 643kW (862shp) and comes with a factory-installed value improvement package (VIP) kit, increasing hot and high power by up to 8% and fuel efficiency by up to 2%.
The Bell 407GXP has a maximum cruise speed of 246km/h and can reach a maximum altitude of 5,733m. It has a maximum range of 624km and an airborne-endurance of four hours.
