Aiming at the problem of antisubmarine patrol aircraft using aerial homing depth charge in ASW， based on the analysis of basic attacking submarine process and bomb dropping aiming method， the effectiveness evaluation model of antisubmarine patrol aircraft sequentially releasing aerial homing depth charge is established． Through a large number of simulation calculations， this paper analyzes the influence of bomb dropping parameters on attack submarine effectiveness under depth charge releasing sequentially when submarine target is adopting maneuvering confrontation． Finally， the basic methods of antisubmarine patrol aircraft sequentially dropping aerial homing depth chargs are summarized， which has some reference significance for antisubmarine combat．
