초록

본 연구에서는 실기체 환경 모사(고도 모사)가 가능한 극초음속 Ludwieg tube 개념설계 도구를 개발하고, 전산유체해석을 통해 Ludwieg tube 개념설계 도구의 성능을 검증하였다. 극초음속 Ludwieg tube 개념설계 도구를 개발하기 위해 Ludwieg tube의 작동원리를 연구하였고, 도구를 활용하여 목표 성능을 만족하기 위한 Ludwieg tube의 제원을 결정하였다. 마하수 4에서 10의 유동을 모사할 수 있고, 특히 마하수 4 유동은 고도 모사가 가능하다.

A preliminary design tool of a hypersonic Ludwieg tube facility which simulates real-flight environment was developed and its performance was verified by CFD(Computation Fluid Dynamics) calculations. The operating theory of Ludwieg tube was studied to develop the preliminary design tool. Using the preliminary design tool, Ludwieg tube specifications were determined to satisfy target performance. The Ludwieg tube which produces high speed flows(the Mach number ranging 4 to 10) was designed. Especially altitude simulation at Mach 4 flow could be performed.
