Abstract

The plume from the attitude controlling rocket motor nozzle has an obvious effect on the aircraft in vacuum. The computation based on the Simons model for vacuum plume was presented, which considers the expansion of the isentropic core and boundary layer. The vacuum plume parameters distribution was obtained. It is shown that the Simons model is a rapid estimation method for vacuum plume calculation in the design of the attitude controlling rocket motor nozzle used on the satellite, airship and other aircraft, as well as its test research.
