METHOD FOR JUNCTION OF SECTIONS WITH REMOVABLE FLANGES Russian patent published in 2021 - IPC B64C1/00 F42B15/36 B64G1/64 

FIELD: aviation.

SUBSTANCE: invention relates to the field of aviation and rocket technology, primarily to aircraft junction units. The method for junction of sections with removable flanges includes manufacture of pins, nuts, flanges of the adjoining sections. The flange of one of the compartments is therein made removable. The flange of the other compartment is also made removable. Protrusions distributed in diameter are therein made on the flanges and profiled cuts matching the protrusions on the flanges are made on the sections, ensuring fixation of the flanges in the longitudinal direction during installation and rotation thereof at the estimated angle. The flanges are blocked from rotation around the longitudinal axis by means of retainers wherefor holes are made in the sections and the flanges for installation of the retainers.

EFFECT: provides reliable fixation of the flanges regardless of the operating temperature, allows installation of blocks with overall dimensions larger than the inner diameter of the flanges in any of the sections, increasing the filling coefficient of the product in general and ensuring that the sections are blocked from mutual rotation under conditions of vibration loading.
