TRANSFER COMPARTMENT OF SPACE MISSION VEHICLE ASSEMBLY-PROTECTIVE UNIT Russian patent published in 2014 - IPC B64G1/22 F42B15/36 

FIELD: transport.

SUBSTANCE: invention relates to design of spacecrafts for delivery of large-dimensioned payloads (PL) included in spacehead to desired injection orbits. Transfer compartment (TC) of missile assembly-protective unit contains external and internal conical shells with rigidly interconnected lower and upper interface rings. The external shell is intended for mounting payload fairing (PLF). The internal shell has intermediate frame and transverse-longitudinal skeleton for PL attachment. Upper interface rings are interconnected by heavy-duty rods and contain attachment locks and pushers of PL compartment. Upper interface ring of inner conical shell of PL attachment is performed in transversal plane of variable cross-section thus creating TC longitudinal axis displacement relative to PL longitudinal axis. Upper interface ring has recesses for pushers spanned by collars rigidly attached to inner conical shell. PL attachment locks are fixed by means of fittings in upper interface ring of inner conical shell, which are as pushers located concentrically to its inner contour. Transverse-longitudinal skeleton of inner conical shell is reinforced between upper interface rings and intermediate frame in places of pusher mounting by corner plates, and in places of lock mounting by beams of variable cross-section to provide TC rigidity. Cut for pusher is made on inner conical shell under one of recesses in the place of less cross-section of upper interface ring. Heavy-duty rods are made length adjustable.

EFFECT: enhancement of operational functionality and efficiency of TC use for large-dimensioned payload displaced relative centre of mass while maintaining stability and controllability of SMV.
