전산유체역학을 통한 PAV 의 로터 블레이드 축간거리에따른 호버링 성능 변화 연구

A Study on Hovering Performance of Personal Air Vehicle According to Distance between Rotor Blade Axis via Computational Fluid Dynamics

초록

In this study, the conceptual design and performance evaluation of a personal air vehicle (PAV) is presented, which is a potential futuristic individual transportation. The blade element theory (BET) is employed to compute a rotational velocity. A computational fluid dynamics (CFD) simulation is performed to investigate the difference in the thrust performance in the rotor axis distance of a quad-copter PAV in hovering. Modal analysis is performed to create a Campbell diagram to investigate critical speed. Consequently, a quad-copter PAV changes the aerodynamics thrust and critical velocity according to the rotor axis distance
