| 説明 | This interior view of the Variable Density Tunnel (VDT) at the NACA's Langley Laboratory, taken shortly after it opened in 1922, looks downstream. Note the wooden construction, the propeller in the background and the observation windows. These windows aligned with small portholes in the pressure shell.NASA Media Usage GuidelinesCredit: NASAImage Number: L-405Date: Circa 1926 |
