AI Technical Summary
Existing propellant/liner/insulation layer interface strength testing devices cannot perform multi-angle testing, and the fixture design is not suitable for wall-mounted cast propellants, thus failing to reflect the bonding interface strength under complex stress conditions.
A multi-angle testing device for the mechanical strength of the bonding interface of wall-mounted cast propellant was designed, including a first mold plate and a second mold plate. Multi-angle testing is achieved by combining the mold plate and the tension plate, and it supports the testing of semi-cylindrical, rectangular and cylindrical propellant specimens.
It enables multi-angle testing of propellant bonding interfaces, improves the applicability of the testing device, and can complete tensile and shear strength tests on specimens of different shapes, providing a design basis for the structural integrity of propellants under complex stress conditions.
