High Pressure Driven Disc Interior Ballistic Characteristics Of Theoretical Analysis And Experimental Research

Currently multiple active protection system of tank have successfully intercepted the anti-tank rockets, anti-tank guided missiles and other low speed anti-tank ammunition except APFSDS in testing and actual combat. This article presents a method that can be used in the active defense in tank or armored vehicle--using high-pressure-driven frisbee to intercept APFSDS and other anti-tank ammunition.According to the requirements of active protection systems, we proposed the high pressure driving frisbee scheme, established a high-pressure-driven theory model. With the method of numerical simulation to the120mm diameter high pressure driving Frisbee for interior ballistics movement, the frisbee got427m/s moving speed and12000r/min rotation speed, the simulation results coincide with the theoretical results.By using the dimensional analysis method, we got the interior ballistic similarity criteria group of the driving Frisbee, established the approximation simulation program of interior ballistic, designed a50mm scaled model of frisbee and a high-pressure driving device of the120mm Frisbee. Model test was carried out and the frisbee model was driven to about183m/s, the test results coincide with the theoretical calculation results. The prototype frisbee could be driven to440m/s, which was in good agreement with the theoretical results.In Conclusion, it is feasible that the frisbee could be driven to a high moving speed and rotation speed by a high driving pressure in a short driving distance. In this paper, the scheme and conclusion provide some ideas or reference for tank active protection system development.
