The study of wind resistance testing equipment for unmanned helicopter

In this paper, a wind field was designed to meet the test requirements through analyzing the experimental requirements of unmanned helicopter wind resistance. If we want to test the performance of UAV wind resistance, we have to get the wind speed at the UAV. There are two problems that we would to face, one is that it is a wind field with wind speed decay, and the other is that we want to do this experiment in which the UAV be the flying state further more the UAV does not carry instruments for measuring wind speed. We propose a method to test the wind speed where the location of the UAV in a wind field with wind speed decay for these two issues. Experimental equipment contains wind speed sensors, variable frequency fan and servo mechanism and so on. Considering the communications equipment this of this program have many type and we need a large number of such devices. Using a multi-threaded multi-serial bus-type communication, making each serial bus has a unique role.
