高超声速飞行器模型弹性特性影响的机理分析
Mechanism Analysis of the Elastic Effects of the Hypersonic Vehicle
摘要
Abstract
Elastic effects on aerodynamics and the coupling of the propulsion system is important in hypersonic vehicle modeling.Based on hypersonic vehicle geometry and mechanism analyses,the aerodynamics and the thrust after elasticity of the vehicle and some other parts were computed.Simulations show that the elastic vibration can change flexible modes and the aerodynamic layout,and lower flexible modes play a leading role in affecting the vehicle.The influence of the elastic effects cannot be neglected in air vehicle modeling.关键词
