4-Foot Supersonic Pressure Tunnel

(L-62227): This view of the 4-Foot SPT’s test section shows a Bell XS-2 model mounted horizontally to allow changes in yaw. The sting shifted on the horizontal strut to change the angle of attack. The strain gage circuits measuring forces were easily adjusted to compensate for gravity, making the model’s orientation irrelevant.
