对影响掠海飞行导弹性能和操纵能力的非定常气动力效应进行了初步研究,旨在确定能使非定常气动力对导弹飞行产生不利影响的各种飞行条件(海情,导弹速度及大气现象)。作用在导弹上的非定常气动力是由阵风引起的,而阵风又是由于海浪的周期性和恶劣的大气现象(例如,飑风)造成的。文章将讨论(以跨音速小扰动和单位阶跃理论为基础的、用于简化导弹的)非定常气动力预测方法与可用于模拟高度控制的自动驾驶仪的仿真方法相结合的可能性。为了确定非定常气动力对导弹飞行的影响,对各种海情进行了仿真研究。研究表明,导弹在恶劣海情或飑风情况下,会出现控制问题。
A preliminary study of the unsteady aerodynamic effects affecting the performance and maneuverability of sea-graded missiles has been carried out to determine the various types of flight conditions (sea conditions, missile speed and atmospheric phenomena that can cause unsteady aerodynamics to adversely affect missile flight) ). The unsteady aerodynamic forces acting on missiles are caused by gusts, which are due to the periodicity of the waves and the harsh atmospheric phenomena (for example, breeze). The article will discuss the possibility of combining unsteady aerodynamic prediction methods based on transonic small perturbations and unit step theory for simplified missiles with simulation methods that can be used to simulate height-controlled autopilots. In order to determine the impact of unsteady aerodynamics on missile flight, various sea conditions were simulated. Research shows that there are control problems with missiles in harsh sea conditions or windy conditions.
