STRUCTURAL ELEMENTS TO INCREASE SAFETY OF AIRCRAFT WITH SOFT WING Russian patent published in 2016 - IPC B64C3/30 B64C31/36 B64C31/24 

FIELD: aviation.

SUBSTANCE: group of inventions relates to aircrafts heavier than air with a soft wing. First version. Hollow soft wing with an air intake at a tip, the cavity of which is divided into a front and rear segments by a pocket in the form of a webbing, three sides of which are sewn in the middle part of the profile chord to one of the surfaces of the wing and two adjacent ribs in such a way, that with the blown rear segment the free end of the webbing lies down on the wing inner surface with its fourth side forming a return valve. Second version. Hollow soft wing with an air intake at the tip comprising valves in the area of air intakes, the petals of which have four edges, one of which is curved and narrowed at the center, is sewn to the edge of the air intake, and two adjacent to it edges are straight and sewn to the adjacent ribs. Third version. Hollow soft wing with an air intake at the tip, including corrugation system ropes connecting the air intakes and made in the form of loops fixed on the axle-pin of a further when opened section and inserted through eyelets in the rib and on the edge of the previous, when opened, air intake section and fixed by axle-pins attached to the edge of the air intake section. Suspension of a hollow soft wing has loops for attachment of the suspension system at the bottom and free ends with loops for attachment of strings at the top. Ends at the place of the beginning of branching have connections with flexible links secured on the suspension system. Motor suspension of the hollow soft wing is made with the loops for attachment of a suspension system at the bottom and a power plant - at the back, as well as free ends with loops for attachment (hooking) of strings at the top. Hooking loops of the suspension system and the power plant are fixed on a rigid frame of top front, lower front and lower back safety arcs.

EFFECT: group of inventions is aimed at an increase in safety.
