Abstract:
Large caliber machinegun duplex ammunit ion is a kind of aux iliary cart ridg e of machineg un cart ridge. Because it consist s of tw o bullets, sensing device can’t be used to measure velocit ies of tw o bullets at the same t ime. A test method for obtaining duplexammunition’s velocity using Doppler radar is presented. Doppler measurement and data processing principles have been int roduced. The measurement has been carried out to achieve velocity- t ime relation curves of the duplex ammunit ion, and therefore the init ial velocit ies and drag coeff icient s of the tw o bullets of the duplex ammunit ion have been calculated. The test result s proved that there is a fairly f ix ed velocity difference betw een the two bullets, and the pattern of the velocity-time of the tw o bullets is mainly identical. The result s are reliable for study of large caliber machinegun duplex ammunition.
