Preliminary Design of Tracking Loop for Marine - Used Machine Gun.
AbstractThis study develops conventional use of 20 mm twin machine gun to provide defence against close-in-air threat. For expanding the field of usage of machine gun and promoting defence ability in naval combat, this study offers a preliminary design of tracking loop, which includes the man-in-loop's scheme. Accuracy and stabilisation are the main considerations for a shipboard weapon design and are included in design. In numerical simulations, the stabilisation of gun mount and carriage platform in tracking loop under large disturbances induced by sea waves is assessed first. Two typical scenarios proceed with the testing of tracking performances. Simulation results demonstrate the effective performance of designed tracking loop subject to environmental disturbances.
