A driving device for a solid attitude and orbit control engine gas regulating valve comprises a power system device, a servo transmission device and a gas valve device, wherein a motor power output shaft in the power system device runs based on a program instruction; one side of an eccentric hinge pin in the servo transmission device fits the motor power output shaft in a D form, and the other side of the eccentric hinge pin of the servo transmission device fits an eccentric rod shaft hole; one side of an eccentric rod is fixedly connected to one side of a throat bolt rod; when the motor poweroutput shaft is rotated, the eccentric hinge pin is driven to synchronously eccentrically rotate, and the eccentric rod drives the throat bolt rod to forwards and backwards move along a guide support; effective working area is realized through a matching surface between one side of an injecting pipe in the gas valve device and the throat bolt rod; when the throat bolt rod forwards and backwards moves, the formed effective working area changes together, and the thrust force produced by high-temperature gas flowing through an outlet of the injecting pipe changes synchronously, so that the thrust force of a thrust solid rocket engine can be continuously adjusted. The driving device has the characteristics of being small in size, high in efficiency, and high in accuracy.
Description
technical field [0001] The invention relates to a driving device for a gas valve, in particular to a high-precision driving device for a gas valve which is used for a solid attitude orbit control engine and has the characteristics of light weight, fast response, continuously adjustable thrust and the like. Background technique [0002] Since the beginning of the 21st century, the development of air strike weapons has risen to a new level. The targets of air defense missiles have been developed to include aircraft, unmanned aerial vehicles, tactical ballistic missiles, cruise missiles and various air-to-ground missiles. What's more, due to the increasing threats from outside the atmosphere, high-altitude anti-missile and anti-satellite issues have received increasing attention. In response to the threat of modern air strike weapons, anti-aircraft missile technology is developing in the direction of long-range, high mobility and multi-purpose. At the same time, in order to im...
