超紧凑型进气道气流控制技术

现在和未来的作战飞行器,推进系统对于飞机的费用、质量、体积、生存力、性能和总体外形都起着至关重要的作用,常规设计技术已经无法满足未来的高隐身、超短型进气道的设计目标,主动流动控制技术提供了一种途径来满足这一需求。本文对进气道主动气流控制的方法和效果、气流控制理论及数值模拟技术作以介绍。

Ultra-Compact Inlet Flow Control Technology

The propulsion system for current and future combat air vehicles is critically important in terms of cost,weight,volume,survivability,performance,and configuration.Conventional aerodynamic design technology can not achieve future ultra-compact inlet system design goals.The active flow control technology offers the potential to meet these requirements.Active inlet flow control approach and effects,inlet flow control theory,numerical simulation technique and limited analysis are presented in this paper.
