ASSEMBLY DEVICE FOR INCREASING THE LIFTING STRENGTH OF A FIXED-WING AIRCRAFT Russian patent published in 2023 - IPC B64C27/26 

FIELD: aviation technology.

SUBSTANCE: invention relates to the field of aviation, in particular to the designs of rotary-wing aircraft. The lifting device (300) assembly comprises a wing (102) and at least a vertical propeller (118) located under the wing (102). The vertical axis (121) of the vertical propeller (118) passes within the wingspan (102). The vertical propeller (118) operates during the horizontal flight of the aircraft. The placement distance (122) between the leading edge (108) and the vertical axis (121) of the vertical propeller (118) depends on the number of revolutions of the propeller (118) per minute, the angle (116) of the wing attack and the chord (117) of the wing.

EFFECT: lifting device (300) assembly creates an increased lifting strength exceeding the sum of the lifting strength values generated by the wing (102) and the propeller (118) separately, which makes it possible to reduce the size of the wing and, accordingly, reduce drag.
