大型低速风洞尾撑机构研制

Development of Tail Support Mechanism for Large Low Speed Wind Tunnel

尾撑机构是为大型低速风洞研制配套的多用途支撑设备,其主要用途包括:支撑战斗机模型完成大迎角状态测力、测压试验任务,迎角连续变化范围-15°~90°,侧滑角连续变化范围±35°;支撑大尺度模型(最大翼展达6 m)完成常规测力、测压、地效试验等任务,满足迎角连续变化范围-10°~75°;支撑特殊模型进行特种试验,包括细长体模型、螺旋桨模型、动力模拟试验模型等。标模试验验证结果表明:该机构刚性强,模型支撑牢固,运行灵活,模型姿态变化定位精确,可满足常规和大量特种模型支撑和姿态变化需要。

The tail support mechanism is a multi-purpose support equipment developed for a large low-speed wind tunnel.Its main uses include supporting the fighter model to complete the task of measuring force and pressure at high angles of attack,with the continuous range of angles of attack from-15°to+90°and the continuous range of sideslip angle from±35°;Support large-scale models(with a maximum wingspan of 6m)to complete conventional force measurement,pressure measurement,ground effect test and other tasks,and meet the continuous change range of angle of attack from-10°to+75°;Support special models for special tests,including slender body models,propeller models,dynamic simulation test models,etc.The standard model test shows that the mechanism has strong rigidity,firm model support,flexible operation and accurate positioning of model attitude change,which can meet the needs of conventional and a large number of special model support and attitude change.
