Exterior Ballistic Discrimination Method of a Mortar Bomb Based on Turbine Alternator Output.

Based on turbine alternator as a velocity sensor to discriminate trajectory, a new feasible trajectory discrimination method was put forward. Output frequency characteristics of turbine alternators and variable function of trajectory velocity were analyzed, considering various state of turbine alternator rotation. systematic scheme of trajectory discrimination was set up by use of turbine alternator outputs, and realization process of trajectory discrimination was depicted detailed. Moreover, establishment process of basic functions for trajectory discrimination was discussed by instance simulation. The simulation result indicates that calculation workload and error of trajectory discrimination are small and acceptable, therefore, with the addition of turbine alternator application on fuzes, the new trajectory discrimination method is feasible.
