Abstract

In this study, the velocity distribution and pressure of the flow with the shape of the aircraft were analyzed to investigate its flight performance. In order to compare the flow rate and its pressure applied on the surface of airplane each other, models A and B have the blunt and sharp shapes as the distinctive shapes of airplanes. It can be inferred that the lower the maximum speed of the flow around the airplane, the less resistance the navigation produces, the less fuel consumption, which is more efficient for the sharp model B than the blunt model A. As the result of this study, the wing area and the head part of the body should be designed to withstand the pressure greater than the body. It is shown that the sharp model B can withstand more pressure due to flow than the blunt model A.

본 연구에서는 항공기의 형상에 따른 유동의 속도 분포와 압력을 해석하여 그 비행 성능을 조사하였다. 비행기에 표면에 부하되는 유동 속도와 그 압력을 서로 비교하기 위하여 뚜렷한 형상의 항공기들로서, Model A와 B는 뭉툭하고 날카로운 형상을 지니고 있다. 비행기 주위에 흐르는 유동의 최대속도가 적을수록 운행의 저항이 덜 발생하여 연료 소모가 줄어든다는 것을 유추할 수 있으며 이는 뭉툭한 model A보다 날카로운 model B 가 더 효율적인 것을 확인할 수 있다. 본 연구 결과로서는 날개 부위와 본체의 헤드 부분을 몸체보다 큰 압력을 견딜 수 있게 설계해야 하며 뭉툭한 형태인 Model A로 설계하였을 때보다 Model B인 날카로운 형태로 하면 유동에 의한 압력을 보다 더 버틸 수 있다고 보인다.
