The initial trajectory numerical simulation of air launched missile;

Influence on initial trajectory of large electric power torpedo caused by battery activated outside tube;

Analysis of effects of torpedo′s weighing property on initial trajectory

Aerodynamic characteristics and initial ballistic interference on a missile by a helicopter s rotor down-wash in hovering;

On the basis of ballistics and missile flight mechanics, initial velocity, angle of fire and stability of initial phase ballistic curve of anti tank missile are analyzed and calculated.

An optimal selection algorithm based on grey relational analysis is proposed to select the optimal group from multiple groups of satellite initial orbits,which are determined via various data sources by Space TT&C(Tracking,Telemetry and Command) Center.

Theoretical analysis was proposed in the optimal selection of spacecraft initial orbits during the orbit injection phase,and an algorithm based on grey relational analysis was proposed to select the optimal initial orbit.

The affection of the torpedo incipient trajectory of the surface warship swaying;

Being Expounding the conception of torpedo incipient trajectory to ensure effective usage and reduce the lost and shorten the test time for torpedoes, this paper researches the mometumtherorim and the twist therorem to establish the incipient trajectory mathematic model of the surface warship launching torpedo.
