THRUST TRANSFER APPARATUS FOR IGNITION TEST OF SOLID ROCKET ENGINE IN FORM OF REAR SKIRT CONNECTION

摘要

A thrust transfer apparatus for an ignition test of a solid rocket engine in a form of rear skirt connection, comprising a front end connecting plate (16), a base (20), a rear skirt connecting plate (14, 17), an arc-shaped seat (12), a connecting rod (11), and a hoop (13). The lower surface of the base is connected to a test movable/fixed frame platform; the front end connecting plate is fixed to one end of the base in a right-angle welding manner, and the front end connecting plate is connected to a force measuring assembly required by the test; the rear skirt connecting plate is connected to a rear skirt flange plate of the solid rocket engine, the rear skirt connecting plate is of an upper-lower split structure and is divided into a rear upper connecting plate (14) and a rear lower connecting plate (17), and the rear lower connecting plate is fixed to the other end of the base in a right-angle welding manner; the center of the rear skirt connecting plate consisting of the rear upper connecting plate and the rear lower connecting plate is provided with a central through hole having an aperture larger than the diameter of a cylinder at the rear skirt part of the fixed rocket engine to be tested; the arc-shaped seat is mounted on the base in a height-adjustable manner for directly supporting the solid rocket engine; and a detachable thrust connecting rod is mounted between the front end connecting plate and the rear skirt connecting plate.
