A new explosive bellows, which has a diameter of 8.0 ㎜ and a length of 25.4 ㎜, was developed for a warhead fuze. The new explosive bellows delivers a thrust of 4.5 ㎏f over a stroke of 25.4 ㎜. 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.

This paper presents light transmission efficiency by optical adhesive thickness between MLA and aperture layer and by aperture hole size. The gap between MLA and Aperture layer is adjusted by the shim. The more optical adhesive thickness increases, the better light transmission efficiency increases up to a point. After that, the light transmission efficiency decreases because stray lights cannot transmit through the aperture layer owing to cut-off by aperture layer. And as a result of light transmission efficiency with changing aperture hole size, the light transmission efficiency is proportional to area of aperture hole. The more specified process is made, the better data and sample will be got.
