Aerodynamic Analysis of Counter-Rotating Propfans Around a Missile-Like-Body Using a Frequency Domain Panel Method

주파수영역 패널기법을 사용한 유도무기형태 동체에 장착된 엇회전식 프롭팬의 공력해석


Abstract

The aerodynamic analysis of a $6{\times}6$ counter-rotating propfan around a missile-like-body has been completed analytically using a frequency domain panel method. The present method requires Fourier transformation of flow field around the propfan in computing the velocities normal to the propfan lifting surfaces. The aerodynamic performance curve is determined by angle of attack and nonuniform inflow conditions. The inflow conditions result from the variations of missile flight speed, angle of attack, propfan location relative to control surfaces and control surface deflection angle. The two cases of propfan location relative to control surface, front and behind, are analyzed and the aerodynamic results are presented.
