An Axisymmetric Shaped Nozzle for Wind Tunnels,
FOREIGN TECHNOLOGY DIV WRIGHT-PATTERSON AFB OHIO
Pagination or Media Count:
The proposed axisymmetric shaped nozzle for wind tunnels with low density flow, such as hypersonic, is made of separate rings with adjustable slots between them for boundary layer suction. In order to simplify the design and to reduce it, the size of the nozzle is made with two female chambers. The chambers are insulated one from another by a movable partition and are connected by channels with the cavity of the working chanber. In addition to this, an ejector is mounted in the channel of the end chamber to increase the boundary layer suction.
