| 内容記述 | Results are presented from wind tunnel tests of the novel, 'fixed shutter' observatory dome concept, which is intended to minimize wind shake effects. In order to enclose larger telescopic apertures, this design allows an upper spherical segment to rotate under a shell of slightly larger diameter which is fixed to a lower rotatable segment. A side-by-side wind tunnel test comparison of this and a conventional dome shows that the mean and fluctuating velocity through the aperture and in the center of the new dome are lower than those of conventional domes, thereby lowering the likelihood of flow-induced telescope vibration. |
