可两次同步展开的三片花瓣式一维弹道修正阻力器

Three Petal Type One-dimensional Trajectory Correction Resistance Mechanism with Two Time Synchronization

文中改进了三片花瓣式阻力修正机构,使其实现同步展开和二次展开。新机构占用空间小,使用弹道修正方式更加灵活。文中阐述了该机构的工作原理,对其机构运动特性和气动特性分别进行了仿真,使用质点弹道方程估计了其修正性能,从多个角度说明了这种阻力修正机构两次展开的可行性与实用性。

In this paper,three petal type resistance correction mechanisms was improved to achieve simultaneous unfolding and the second expansions.The new mechanism has small space usage,and the way to use the trajectory correction is more flexible.This paper describes the operational principle of the mechanism.The motion characteristics and aerodynamic characteristics of the mechanism were simulated,and the particle trajectory equation was used to estimate its correction performance,which explained the feasibility and practicability of the two expansion of the resistance correction mechanism from multiple perspectives.
