Deflecting Features of Gas from Double-Faced Deflector and Structure Optimization of Deflector

This paper uses three-dimensional dynamical simulation of gas jet to demonstrate basic deflecting features of the double-faced deflector, during the launch process of the land-based missile with the vehicle-mounted vertically thermal launch. The calculation shows that the deflection of the gas flow is good, reducing knock-on effect and ablative effect on launch device. But wheels of the launch vehicle are still under visible influent from the gas flow. The paper optimizes the double-faced deflector and compares different suggestions in order to find a better deflection.
