NA Design NA40 "Bongo" · 模型 237006
TYPE: Two-seat ultralight helicopter. DESIGN FEATURES: Two-blade teetering rotor; pod and boom fuselage with inverted Y-tail unit. Cocomo patented anti-torque system eliminates the need for a tail rotor, reduces transmission complexity and operating noise level. FLYING CONTROLS: Conventional cyclic and collective controls. Ducted air anti-torque system. STRUCTURE: Mainly composites, including rotor blades; some aluminum in the fuselage, otherwise double-curvature monocoque sandwich; laminated, vacuum-formed elastomeric rotor head. LANDING GEAR: Tubular twin-skid gear with ground handling wheels. Inflatable permanent or emergency floats are optional. POWER PLANT: TWO 86kW Prvni Brnenska Strojina PBS Velka Bites ТЕ 50В turboshafts, with FADEC and dual ignition. Engines mounted side by side behind the cockpit; transmission via combining gearbox. Single self-sealing fuel tank beneath engines, capacity 210 liters. ACCOMMODATION: Adjustable, foldable, and anatomically shaped seats for pilot and passenger. Baggage space aft of seats; provision for additional, aerodynamic baggage container under the fuselage. Gull-wing window/door on each side, hinged on centreline and opening upward. SYSTEMS: Dual 27V DC electrical systems; external power receptacle. AVIONICS: Instrumentation: VFR standard; IFR to be offered later. EQUIPMENT: Rocket-deployed emergency recovery parachute optional.
