Determining the Optimal Release Altitude for a Fuel-Air Explosive Secondary Detonation Fuze

To maximize the destructive effect of a fuel-air explosive, determining the optimal release altitude for secondary detonation fuze is a crucial problem. In addressing this issue, a six-degree-of-freedom model of the fuel-air explosive is established. Through simulation analysis, identifies the range of release altitudes and velocities for the fuel-air explosive to ensure that the detonation fuze can enter the fuel-air cloud area. A method for finding the optimal release altitude for secondary detonation fuze is devised. Within a reasonable range, multiple sets of initial conditions for bomb release are selected. Simulations are then conducted for different release altitudes of secondary detonation fuze to determine the optimal release altitude for detonating the fuel-air cloud at the ideal detonation delay time. This provides a theoretical reference for the release altitude of detonation fuze during the actual detonation process.
