PILOTLESS AIRCRAFT Russian patent published in 2010 - IPC B64C39/04 

FIELD: aircraft engineering.

SUBSTANCE: invention relates to pilotless aircraft and can be used to produce air platforms to carry loads for long time and over long range in independent and/or remote-controlled flight. Proposed aircraft comprises airframe with two-girder tail, pusher engine-propeller plant, wing, horizontal and vertical empennage, servo units and undercarriage. Airframe structure represents metal frame comprising compartment with onboard radio electronic hardware and fuel compartment. Truss is attached to airframe structure front and engine mount frame is attached to airframe tail, central section of airframe accommodates wing spars. Tubular wing spars can double as extra fuel tank. Tail beams represent metal tubes. Vertical empennage represents two inclined fins with rudders and is arranged on tail beam ends. Horizontal empennage represents a tail plane with elevation rudder. Airframe skin consists of the front fairing, main fairing and engine fairing. Main fairing top accommodates a hatch that covers the compartment with parachute and is arranged above fuel tank.

EFFECT: increased flight range and altitude at high payload-to-take-off weight ratio, improved operating characteristics.
