Abstract: The paper discusses a model for estimating the effectiveness of anti-aircraft small bore shells meant for internal blast and deals with the optimum selection of shell parameters. The vulnerable area is used in the case of internal blast as the measure of effectiveness. A model for estimating the vulnerable area is established, using the case of 37mm frag- mentation-blast shell shoots at a models of aircraft as a concrete example for the calculation. The results show that the optimum explosive charge for t1ne 37mm fragmentation-blast shell is about 120 gram, a value rather close to those used on shells of similar calibre abroad. This model can be used to conduct scheme demonstration and preliminary design as well as evalution of small bore fragmentation-blast shells.
