DEVICE OF THE AERODYNAMIC CONTROL SYSTEM OF THE RETURNABLE REUSABLE STAGE OF THE LAUNCH VEHICLE Russian patent published in 2023 - IPC B64G1/24 B64G99/00 

FIELD: aviation.

SUBSTANCE: invention relates to an aerodynamic control system of an aircraft (AC), mainly the return stage of a launch vehicle, with lattice rudders and stabilizers. The lattice rudders are mounted on the aircraft body in pairs in mutually perpendicular planes. Each contains a frame with a set of plans and is connected to the steering gear located in the aircraft body by means of a hinged shaft. On the body under each lattice steering wheel there is a lattice stabilizer, consisting of a set of plans and a turning unit made in the form of a power box. The box is hinged on the side of the basal part on the body of the aircraft in the ears. The hinge joints of the stabilizer and steering wheel are installed coaxially. A wedge-shaped fairing is installed on the stabilizer box on the windward side.

EFFECT: increased efficiency in terms of the quality and reliability of aircraft control while improving the conditions for its flow around the hypersonic flow.
