Abstract

A test stand for an altitude test of reciprocating engine was designed, manufactured and validated by preliminary tests and simple calculations. The test stand was designed to interface with the altitude turbo-shaft engine test facility of Korea Aerospace Research Institute. Many limiting conditions for altitude test of reciprocating engine were assumed and the test stand was developed to satisfy these limitations. The test stand design was focused especially on the altitude, Mach number and fuel temperature control for reciprocating engine altitude tests with smaller air and fuel flow than those of turbo shaft engines.

중소형급 무인 항공기에 활용되고 있는 왕복동 엔진의 고도시험을 위한 시험 장치를 설계 및 제작하였으며, 예비 성능시험과 계산을 통하여 활용가능 여부를 판단해 보았다. 시험 장치는 현재 한국항공우주연구원에서 운용 중인 터보샤프트 엔진 고도시험설비에서 활용이 가능하도록 구성하였으며, 왕복동 엔진의 고도시험을 수행하기 위한 각종 제한조건을 가정하고 이를 만족할 수 있도록 개발하였다. 특히 대유량의 공기와 연료가 필요한 터보샤프트 엔진에 비하여 적은 유량이 필요한 왕복동 엔진의 성능시험을 위하여 고도 및 비행 마하수 조건의 제어가 가능하도록 장치를 구성하였으며, 엔진에 공급되는 연료의 온도를 보다 손쉽게 조절할 수 있는 장치들을 개발하였다.
