Aerodynamic Simulation and a Test Technique for Investigation of a Flight Vehicle with Jet Engine in Front Position and Lattice Fins

摘要

A separated nose section of a launch vehicle with an emergency rescue system (ERS) is a flight vehicle (FV) with a jet engine (JE) in the front position and with honeycomb lattice fins (LF) in the base region. The flight vehicle configuration is illustrated in Fig. I above the X-axis and a schematic of its scaled aerodynamic model is shown below the X-axis. Determination of aerodynamic characteristics (AC) for that sort of fight vehicle is a complicated problem which may be solved combining experimental techniques and theoretical calculations. Such work includes the following stages.
