국부적으로 기울어진 지면을 고려한 제자리비행 로터의 비정상 하중 소음 측정
Measurement of Unsteady Loading Noise from Hovering Rotor with Partially Inclined Ground
- 발행 : 2008.04.17
초록
Experiments are performed to consider the ground effects on unsteady loading and acoustic generation. Partially inclined plate is used to maximize the unsteadiness of the rotor. Indirect method to recognize the unsteady effect is used by measuring the noise in the normal direction from the rotor plane. The experiment is conducted with a square plate of about
