水下齐射扰动特性

Focusing on the multiphase flow with heat and mass transition and the motion coupling process of underwater vertical salvo, a numerical calculation model of multiphase flow, slender body motion and deformation load of the adapter module was established to study the characteristics of salvo interference. The results showed that the lateral fluid load and the deformation of adapter module influenced the launching trajectory significantly. In the course of launching, the lateral displacement reached 0.1 times the length of the body and the lateral attitude angle reached 7°. In addition, the flow backward and bubble overflow process of canister outlet after the launch of the first slender body had a significant influence on the bubble shape, load state of the second slender body, as well as the trajectory. In the current case, the difference of lateral attitude angle between the first and second launching bodies is about 0.1° at the leaving moment, and the difference of angle velocity reaches 7.5(°)/s.
