Paper Abstract

In the field of conventional precision guided weapon design, the aircraft dome is generally designed as part of a hemispherical dome or hemispherical dome. Hemispherical domes are easy to produce, detect and correct aberration, but hypersonic vehicles equipped with hemispherical domes generate huge air resistance and a large number of aerodynamic thermal effects during atmospheric flight, seriously affecting the working conditions of precision guided weapons. Therefore, the paper breaks through the traditional spherical dome shape design, establishes the conformal dome model of freeform surfaces such as von Karman curve, quadratic curve and sine curve, and analyzes and compares the aerodynamic thermal performance of the above-mentioned various surface domes with finite element method. The conclusion is drawn that the optimization of the dome surface based on different free curves can effectively improve the aerodynamic thermal performance of supersonic precision guided weapons and reduce the influence of aerodynamic heating on its working state.
