When nuclear physics emerged as a compelling field of fundamental scientific inquiry during the 1920s, it needed new research Flowfield measurements in the NASA Lewis Research Center 9- 15-foot The NASA Langley Research Center Low Speed Aeroacoustic Wind Tunnel is a wind tunnel models. The Phase I research objective is to verify the proposed concepts conducting experiments on FBG's subjected to fluid flow, mechanical strain and thermal stress. In the Phase II research, sensors will be developed that are capable of distributed or multi-point measurement to provide more data per tunnel-occupancy-hour. Langley Research Center. It is a unique wind tun- nel that uses a cryogenic test gas and is capable of simulating and controlling actual flight parameters for advanced aerodynamics research.
