| Armament, especially from the 1990s, has being improved dramatically owing to the development of science and technology. Now various kinds of new weapons have been applied in military training and some local wars in the world. Cargo projectile, as an important new weapon, has also being put into common use. In order to prove the efficiency and take a better advantage of it, it is necessary to make an all-round analysis of the tactical technology indices.Starting with the analysis of its characteristics and firing error, a model of fire efficiency for air is established in this paper. And on the basis of it, using numerical integration, numerical simulating computation is done. According to result analysis, the factor of fire efficiency is found. The scientific foundations supplied for determining structural parameter and performance parameter of cargo projectile are provided. |
