CFD/RBD Numerical Simulation Research on the Process of Buried Aviation Weapon Launch

Because of its special configuration, the flying wing layout aircraft shows a big difference in performance from conventional aircraft. Embedded weapon cabin can help fighters improve stealth performance, but the door interference and the flow under the cavity structure are more complicated. Multipl...

description	Because of its special configuration, the flying wing layout aircraft shows a big difference in performance from conventional aircraft. Embedded weapon cabin can help fighters improve stealth performance, but the door interference and the flow under the cavity structure are more complicated. Multiple missiles are very likely to collide with each other or contact the weapon cabin during the separation process, affecting the safety performance of the carrier aircraft, so improving the separation quality of embedded weapons is very important. Using an improved non-structural overset grid radial basis function interpolation method, coupling flow control equations and rigid body dynamics equations, the separation process of a conventional “W” type flying wing layout embedded weapons is numerically simulated. In the separation process, the effect of separation interval (0 s/0.01 s/0.03 s) on the separation quality of the projectile is fully considered. The simulation results show that during the separation of the front and rear cabin, the timing separation method can effectively improve the separation quality of the rear cabin separation projectile, and the attitude of the projectile changes smoothly during the entire separation process.
