METHOD FOR SECURING AND DETACHING PAYLOAD Russian patent published in 2022 - IPC B64G1/64 F42B15/36 B64D1/02 

FIELD: aviation.

SUBSTANCE: invention relates to the field of aviation and rocket technology, primarily to aircraft junction units. Substance: the power element of the load-bearing structure is equipped with mechanical locks secured along the periphery, wherein each lock is equipped with an L-shaped rotary link divided by an axis of rotation into a gripping arm ensuring the gripping of the protrusion of the power element of the payload from the rear side, and a support arm interacting with the locking link, made in the form of a rod equipped with transverse sliders and a stop located under the arm, in the gripping position. The locking apparatus is made in the form of a threaded hole in the gripping arm and a bolt screwed into the threaded hole. Each locking link is connected by a metal cable with a tension drive made in the form of a cylinder with a piston and an insertable rod. The metal cables are provided with a metal winding configured to ensure sliding of the metal cable. The under-piston plane of the cylinder is communicated with the source of overpressure fluid medium through the starting apparatus, the area of the piston is selected sufficient to be moved by the overpressure of the fluid medium in the under-piston cavity and for the rod of each lock to be removed from under the stop arm. When securing, the bolts are tightened in the gripping arms. Detaching is provided by pushers after the starter is triggered.

EFFECT: ensured securing operability under heavy loads, facilitated configuration, simplified manufacture, and reduction in the aerodynamic resistance.
