| Abstract: | The significance of the model to play a "flying platform"in spin free-flight test is expounded. The principles to select the model scale factor K are explained. The various factors influencing the model mass m_m which must agree with the dynamic similarity requirements are analysed in detail.The problems determining both height H_A of the airplane falling into a spin and height H_m of simulated test of the free-flight model in close relationship with the model design are analysed. The principle problems about the recoyery system design and the model structural design are also discussed simply. |
