【摘要】 飞机失速时会旋转下坠,为了研究该状态下的空气动力学问题,设计并实现一套应用于风洞旋转模型的测试系统;该系统硬件采用基于PXI总线的数据采集模块,软件设计分为运行管理、数据采集和数据处理3个子系统。在各子系统之间通过DataSocket通信技术实现指令及数据的传输,由用户以中心调度的方式指挥各子系统完成相应功能;该测试系统在已成功应用于试验,并取得了良好的效果,这种设计逻辑结构清晰,自动化程度高,并具备了较强的通用性。更多还原

【Abstract】 The test system for rotary balance in wind tunnel is established in order to study the aerodynamics phenomenon when aircraft stalls in the air.The measurement module of PXI bus is adopted in the system hardware,and the software is devided into three subsystems.Information and data is transmitted by DataSocket communication technology among subsystems.The user instructs each subsystem to accomplish reletive functions.The system is successful in test and gets good application effect,and the design has clear logical structure,with high level of automation,as well as the strong universality.更多还原
