Abstract: Flaming combat is a short-distance combat pattern that causes destruction by using flame jet, playing a unique fire support role in modern wars. But the inherent defect of powder flamethrower on duty makes it unable to meet the actual need of flexible fighting in future combat. Therefore, the design idea of a new type flamethrower was put forward, and ADC model analysis method was established. Through the setup of usability, credibility, and capacity matrices, a system effectiveness analysis model was built for powder flamethrower on duty and the new-type flamethrower, to compare and analyze system effectiveness of the two types of flamethrower. The result shows that the new-type flamethrower has a conspicuous advantage in integral systematic effect and use preservation. The establishment of the ADC model of the flamethrower provides theoretical basis for the demonstration and development of the new-type flamethrower on the foundation of the quantized analysis of the system effectiveness of the flamethrower.
