Two-Torpedo Salvo Method for Helicopter Hovering Attack

Aiming at the current status that helicopter uses single torpedo to attack submarine, a method of two torpedoes salvo for helicopter hovering attack is presented. We establish a model of torpedo hit probability under pure evasive maneuver situation by analyzing the organization of search area of two torpedoes salvo, possible target position area, selection of salvo aiming point, and the submarine evasive maneuver model.Compared to single torpedo attack, the simulation result shows that two torpedoes salvo can improve target detecting probability and has a larger detecting distance under the same condition. Furthermore, the method achieves higher torpedo hit probability under large board angle than the single torpedo attack.
