Abstract

Combining momentum theory and vortex theory, rotor circulation equation was deduced. The rotor down-wash flow field was calculated using generalized down-wash flow model. On this ba?sis, the initial missile trajectory was calculated on both the conditions with and without rotor down- wash flow. The result indicates that the rotor down-wash flow has an obvious influence on the initial missile trajectory.

Key words
