CONVERTIPLANE Russian patent published in 2016 - IPC B64C29/00 B64C27/28 B64D27/24 

FIELD: aviation.

SUBSTANCE: invention relates to designs of vertical take-off and landing aircrafts. Convertiplane (1) comprises two half-wings (3), at least one first propeller (4), containing shaft (6), which can rotate about first axis (B) and turn about second axis (C) together with first axis (B) relative to half-wings (3). First axis (B) is transverse to convertiplane longitudinal direction (A) comprises (1) in helicopter mode and is parallel to longitudinal direction (A) in aircraft mode. Convertiplane (1) comprises reservoir (70; 81, 82) of electric energy. Electric machine (71) includes stator (72), which is electrically connected to energy accumulator (70; 81, 82), and second rotor (73), which is connected to shaft (6) of first propeller (4). Electric machine (71) acts as electric motor to drive said first propeller (4) using electric energy accumulated in accumulator (70; 81, 82) or as generator of electric power for charging of accumulator (70, 81, 82) by means of rotation of second propeller (4) under wind influence.

EFFECT: possibility to charge energy accumulator from renewable energy sources.
