After the missile is launched, the umbilical connector should be separated from it without any physical interference. The umbilical separation device, for this purpose, was developed by means of new concept. Using the investigation of various methods to separate the umbilical connector, a suitable method was selected and a corresponding device was designed and manufactured. To ensure the performance of the developed device, numerical analysis and performance test were conducted and correction was followed. The umbilical separation device was applied to real system operation test and its operation performance was tested. In consequence, several problems were founded, however, good results were generally obtained.

Recently, the domestic demand for weapon systems based on aircraft platforms is gradually increasing. In particular, the demand for effective precision guided missile(PGM) which cruises for several hundred kilometers after launch to strike the ground target is rising drastically, but it is in the early stages of development, and research based on it are limited. This paper is a study on the power converter unit(PCU) within PGM which is mounted on an aircraft platform based on MIL-STD-1760, which is an interface between an aircraft and PGM. We investigated the electrical properties and structure of the umbilical connector, and the aircraft/store electrical interconnection system. Also, the focus on the design specifications of the PCU that supplies power were described. This result 3 phase AC input, which is the state for the guided simulation power supply in the state of being mounted on an aircraft that rectification method with power factor correction(PFC) compared to bridge rectifier circuit. In the future, it may be used as a basis for power supply design on aircraft mounted weapon systems.
