Low-Turbulence Pressure Tunnel (LTPT)
(L-49122): This phantom drawing shows the LTPT in the center with its predecessor, the Low-Turbulence Tunnel, in the upper right. The model-preparation room and test chamber airlock are on the second floor of the foreground building. The large air reservoir on the left was originally the Variable-Density Tunnel’s pressure vessel.
