Abstract: The deployment process of transverse folding-wings of missiles is studied. The mathematical model and dynamic simulation model of deployment process of folding-wing in missile launching and ground tests are both established, in which the influences of friction and aerodynamic force are considered. The folding-wing were designed and manufactured. The images of deployment process of folding-wings are obtained using the high speed photography during ground test. The research results show that the test results are in good agreement with those of mathematic and dynamic simulation models. A value range of friction moment is also provided from the test results, which can support the design and application of folding-wing.

Key words: ordnance science and technology, folding-wing, deployment, dynamic simulation, experiment
