A new explosive bellows, which has a diameter of 8.0 mm and a length of 25.4 mm, was developed for a warhead fuze. The new explosive bellows delivers a thrust of 4.5 kgf over a stroke of 25.4 mm. A new gas generator containing BP/MTV ignition charge was also developed and the output test equipment, which measures the length of spring compressed by the function of explosive bellows, was also devised. In order to find out that the new explosive bellows meets the design requirements, the sensitivity tests and output tests were conducted. The test results show that the new explosive bellows meets the requirements and can be applicable to a warhead fuze.
