可调式抗风性能测试系统的研制

Development of Wind Resistance Performance of Adjustable Test System

针对无人驾驶航空器的抗风性能测试,研发了可调式抗风性能测试系统,该可调式抗风性能测试系统主要由控制系统、显示器、调速电机、风扇、导流装置和固定造风装置的外围箱架等组成。系统采用PLC控制,通过调节频率来改变风速。试验结果表明:在自然风速低于2 m/s的情况下,该测试系统生成的有效风场范围为2 m×4 m×10 m(高×长×宽),设置为6 m/s时,可满足植保无人驾驶航空器抗风能力测试的条件。同时,由于风扇和导流装置是以独立风扇为单元设计,所以可以根据实际需求向四周扩展风场范围。

For the wind resistance performance test of unmanned aerial vehicle,an adjustable wind resistance performance test system is developed.The adjustable wind resistance performance test system mainly consists of control system,display,speed regulating motor,fan,guide device and peripheral frame of fixed wind making device.The frequency is controlled by PLC to change the wind speed.The test results show that the natural wind speed is lower than 2 m/s,the effective wind field generated by the test system is 2 m×4 m×10 m(high×long×wide),set at 6 m/s,it can meet the needs of wind resistance test of plant protection unmanned aircraft.At the same time,since the fan and guide device are designed with a single fan as a unit,the air wall can be expanded to the surrounding area as required.
