进、排气系统的综合设计对无人机的气动和隐身特性至关重要,涉及到计算流体力学、风洞试验、结构动力计算和隐身特性计算等多个学科,对这些学科进行综合设计,得到最优化的方案是无人机设计的重要目标。本文结合瑞典防务研究局(FOI)某无人机方案的进、排气系统综合设计方法,对隐身无人机的进、排气系统发展方向进行分析和思考。 The integrated design of intake and exhaust systems is crucial to the aerodynamic and stealth characteristics of UAVs and involves many disciplines such as computational fluid dynamics, wind tunnel tests, structural dynamic calculations and stealth characteristics calculations. The comprehensive design of these disciplines, The most optimized solution is an important goal of UAV design. In this paper, the integrated design method of inlet and exhaust system of a drone program of Swedish Defense Research Agency (FOI) is introduced to analyze and think about the development direction of intake and exhaust systems of stealth UAS.
