A flexible joint and flexible nozzle for wide temperature use
A flexible joint and flexible nozzle technology, which is applied in the directions of jet propulsion, machine/engine, rocket engine, etc., can solve the problem that the structural rigidity and force transmission function of the flexible joint cannot be satisfied, and the use requirements of solid rocket motors can no longer be met. It can not well meet the problems of shear stress and bending moment, so as to achieve the effect of not easy crack propagation damage, improving work stability and reducing negative quality.
