APPARATUS FOR ALIGNING VERTICAL AXES OF TWO STRUCTURES CONNECTED THROUGH GIMBAL JOINT

摘要

PURPOSE: An apparatus for aligning vertical axes of two structures is provided to improve the stability of a rocket when the rocket is initially ignited by simply aligning a rocket body axis with a vertical axis of an engine. CONSTITUTION: A rocket body is connected to an engine through a gimbal joint(2). An engine mount(3) is placed above a rocket engine(1). A pitch axis controller(4) is installed at a pitch axis and a main axis controller(5) is installed at a main axis. A piston is installed in a cylinder. A load end bearing connected to the pitch shaft or flank shaft is provided in the piston. A magnet is fixed to an inner end of the piston. An earth end assembly is connected to the cylinder through a knuckle ring. A position detecting sensor is installed in a housing. A servo controller(8) is provided to control the pitch axis controller(4) and the main axis controller(5). A sensor fixing member(9) is attached to the rocket body axis so as to mount an incline angle sensor(10) thereon. An engine incline angle sensor(7) is fixed to a sensor supporter(6).
