FIELD: transport.
SUBSTANCE: invention relates to aircraft engineering. Proposed aircraft features opposed arrangement of propellers with their rotational axes arranged at fuselage front and rear ends. Fuselage sidewalls are formed by concave surfaces in fuselage midplane under T-shaped wing with lowered tips that allow controlled turn within 90 degrees. Fuselage front part accommodates aerodynamic surfaces of horizontal tail and low vertical tail unit. Fuselage tail accommodates aerodynamic surfaces in the form of inversed V with controlled tailplane flaps and read-drive wheels of non-retractable landing gear. Tail reversible constant-pitch propeller and front propeller may be coupled with common drive shaft via reversing reduction gear, variator and clutch.
EFFECT: higher stability of VTOL, safe gliding with propellers cut off, increased range and horizontal flight speed.
