Abstract: | The paper discusses the method and technique of an experiment and also some results of the investigation of the unsteady pressure on the surface of a rectangular wing executing oscillations with angular amplitude * = 3° at Strouhal numbers p* = 0.113 (p* = /v, where * is the angular frequency, b is the chord of the wing, and v is the velocity of the oncoming flow).Translated from Izvestiya Akademii Nauk SSSR, Mekhanika Zhidkosti i Gaza, No. 5, pp. 178–181, September–October, 1981. |
