Abstract

This paper opens with a brief review of cryogenic wind tunnels and their use for high Reynolds number testing. Emphasis is on operational and aerodynamic testing experience in the NASA Langley 0.3-m Transonic Cryogenic Tunnel (TCT). Since we built the 0.3-m TCT in 1973, it has logged over 8000 hours of running at cryogenic temperatures. We use the 0.3-m TCT for aerodynamic testing and to develop test techniques for cryogenic tunnels.

Areas briefly covered in this paper include development of test techniques and aerodynamic testing in cryogenic tunnels. Based on our experience, we recommend using advanced testing techniques to increase the value of cryogenic tunnels to the research community. These include adaptive wall test sections, using solid but flexible top and bottom walls, magnetic suspension and balance systems and non-intrusive laser techniques..
