大迎角下俯仰振荡对细长体气动特性的影响
Investigation of aerodynamic characteristics on a pitching slender body of revolution at high angles of attack
摘要
Abstract
Computations are performed to simulate a slender body without disturbance flow flied and a slender body with nose-disturbed flow flied. By analyzing the vortex structure of flow field and aerodynamic force, it is showed that both of flow field gradually change from asymmetry to symmetry under the high frequency of small amplitude pitch ing oscillation. Pitching motion has more effect on flow field around the slender body without disturbance compared with the slender body with nose-disturbed in the first period.关键词
