일반적으로 마그네틱 코어(magnetic core)가 삽입되어 있는 구조의 변압기의 에너지 효율을 높이고 적절한 주파수 대역에서 작동시키기 위해서는서 자성체를 이용하여 eddy current를 줄여야 한다. 본 논문에서는 자성체의 적층 형태에 따라 어떻게 eddy current가 영향을 받는지에 대한 전자기적 전산모사를 실시하였다.

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.
