The technique of wind tunnel free-flight test for multi-bodies separation,a more complicated wind tunnel special test technique,has been developed.With this new technique,the multi-bodies separation process of the aircraft can be simulated more accurately,and the whole separation process can be recorded by the high-speed camera.The technique is introduced in detail,include the principle,characteristic,test model design,similarity criteria,and test apparatus.Based on the different characteristic and application fields,the technique of wind tunnel free-flight test for multi-bodies separation can be classified as stage separation,submunition separating from dispenser and multi-bodies separation with additional constraints.Detailed specification is given for each type.The test images and flight path curves of each separated-body are presented.According to the above presentation,the technique of wind tunnel free-flight test for multi-bodies separation,can be well understand and easily adopted by more researchers engaged in wind tunnel test.
