VERTICAL TAKE-OFF AND/OR LANDING AIRCRAFT AND METHOD FOR CONTROL OF FLUID FLOW ON FLUID LINE OF VERTICAL TAKE-OFF AND/OR LANDING AIRCRAFT Russian patent published in 2022 - IPC B64C29/00 B64C27/28 B64C37/00 

FIELD: aviation.

SUBSTANCE: invention relates to the field of aviation, in particular to the designs of rotary-wing aircraft. The vertical takeoff and/or landing aircraft (1) comprises a fuselage (2) having a longitudinal axis (D), a pair of semi-wings (3) protruding from the fuselage (2) in a direction transverse with respect to the longitudinal axis (D), a pair of predetermined areas (11) tearing off the half-wings (3) forming respective preferred fracture sections (12), in which the respective half-wings (3) are designed to tear off, during operation, in a controlled manner, moving along the preferred fracture path in the event of an impact, line (13) fluid medium, made with the possibility of transporting technical fluid medium from the semi-wing (3) and/or to it. The aircraft (1) contains a self-sealing connection (15) movable between the first configuration, in which it maintains the flow of the specified technical fluid, and the second configuration, in which it prevents the aforementioned flow and leakage of the technical fluid from the line (13) fluid. The self-sealing joint (15) is made with the possibility of moving from the first to the second configuration by moving the half-wing (3) along the destruction path.

EFFECT: increased safety of the aircraft during vertical takeoff and landing.
