[0002] A training bomb is a kind of live ammunition substitute used in military training. As a substitute for live ammunition, the training bomb plays a role in training and teaching in the process of daily drills. The existing training bomb mainly has two types. One type does not change the propellant, but replaces the real combat unit with a fake simulated combat unit. The combat unit is consistent with the real combat unit in weight and size, and the launch state is also consistent with the live ammunition, but the cost is relatively high. The second type is a gun instead of a cannon, that is, the gun barrel is arranged in parallel to the cannon barrel, and the training operation is performed according to the operation procedure of the cannon, and the bullet is finally shot out. This method has a lower training cost, but the training effect is not ideal. There is also a kind of training bomb of submunition type, which is better than the former two types, but like the former two types, it cannot simultaneously display the flight trajectory and indicate the landing point position.
