본 연구에서는 유도무기 동체 내에 고체 추진기관을 삽입하여 장착할 경우 적용할 수 있는 연결장치와 조립체 개념을 제안하였다. 유도탄 동체 내에 추진기관을 삽입하여 장착하는 경우는 동체가 비행중 받는 하중에 더하여 추진기관의 연소에 의해 야기되는 여러 가지 효과 즉, 추력에 의한 축하중, 진동, 연소 중 발생하는 추진기관의 축방향 변형 등을 견디는 구조여야 한다. 본 연구에서 제안된 추진기관 연결장치를 통해 간결하면서도 설계 요구조건을 모두 만족하는 추진기관 장착 시스템을 구성할 수 있었다. This paper presents the rocket motor support structure to position solid rocket engine within a missile fuselage. When the rocket motor is mounted inside a missile fuselage, fuselage structure must be designed to withstand various structural problems resulting from inserted rocket motor such as axial thrust force, shock/vibration, axial deformation of the rocket motor tank in addition to the flight loads. The motor support structure system proposed in this paper proved to be very simple and efficient while satisfying all the design requirements.

Independent air-conditioning and heating system for commercial vehicles is possible an cooling and heating environment by battery power without mechanical elements and has the important advantages which reduced fuel-price, minimized environmental pollution caused by emissions. In this study, the voltage and current of thermoelectric module, inside & outside temperature of cabin and internal & external temperature of cooling and heating system were measured after setting up anti-start air conditioning system using the thermoelectric element in the real operating condition. In experimental results, when it is measured and analyzed output voltage and current up to cutoff voltage, it is shown that the capacity of battery power is required approximately two times.
