摘    要:本文对无人机双发助推的同步性进行了研究。研究对象是CK-1M遥控机。实现多发助推的同步性,关键是推进剂特性参数和面喉比保持稳定,确保平衡压强的一致性。此外,点火药量容差及并联电路点火,也是实现多发助推同步性的重要因素。本文采用放样吊线法安装助推器,确保安装精度和左右对称,从而保证了力的精确传递方向,避免了附加力矩的产生。经台架试验和试飞验证,CK-1M双发助推的同步性良好。

关 键 词:无人驾驶飞机  起飞助推器  同步性  对称  平衡压强  面喉比  点火

Abstract:The synchronism of the CK-1M pilotless aircraft with boosters is studied in this paper. To effectuate the synchronism of multi-boosters, the key is to keep the propellent characteristic ajid the surface-to-port area ratio stable,and to ensure the equilibrium pressure consistent. Furthermore ,the tolerance of igniter quantity and the ignition of the parallel circuits are also important factors to realize the synchronism of multi-boosters.The installation of boosters is made by means of lofting plumb line to ensure the mounting precision and symmetry, resulting in accurate force transmition direction, and avoiding the emergence of additional moments. Both the tests on stand and in fight verify that the synchronism of the CK-1M pilotless aircraft with two boosters is good.
Keywords:piiotless aircraft  launching booster  synchronism  symmetry  equilibrium pressure  surface-to-port area ratio  ignition
