MULTI-PURPOSE CRYOGENIC CONVERTIPLANE Russian patent published in 2010 - IPC B64C37/00 B64C29/00 

FIELD: transport.

SUBSTANCE: invention relates to aircraft engineering and can be used in design of multi-purpose convertiplanes. Proposed convertiplane represent a triple-beam monoplane, comprises low wing, spaced apart beams jointing wing with fin-washers connected with vertical tail and tailplane, power plant, transmission with reduction gears, connecting shafts and landing gear. Proposed convertiplane can be transformed from triple configuration with two nose and two propellers between keels in rotary circular channels into helicopter configuration with four rotors (2 + 2) and visa versa. Vertical tail represents tail pylon of two-keel H-like fin with tailplane mounted in tail pylon fairing. H-like transmission comprises T-like front and rear intermediate reducers coupled with reduction gears of nose propellers nose and those mounted between keels. L-shapes systems of shafts with angular reducers allows said shaft to bend in nose fairing and tail pylon. Combined power plant with cryogenic fuel tanks comprises two lift-thrust gas turbine engines and two lift-accelerate turbojet engines.

EFFECT: increased thrust, improved operating performances.
