High Reynolds Number Transonic Ludwieg Tube Wind Tunnel
The high Reynolds number transonic Ludwieg tube wind tunnel has a porous wall test section that measures 19.5 by 23.2 cm. It is an impulse facility with a run time of about 120 ms. The Mach number range is 0.5-1.2 and the Reynolds number range is 4-40 million/meter. The extremely high Reynolds number capability enables full-scale simulation of rotor aerodynamics. The tunnel has a low level of turbulence, with free stream pressure fluctuations of only 1 percent rms. It possesses a 5 component balance.

Famous quotes containing the words high, reynolds, number, tube, wind and/or tunnel:
“How tall the buildings were as I began
To live, and how high the rain that battered them!”
—John Ashbery (b. 1927)
“When Sir Joshua Reynolds died
All Nature was degraded;”
—William Blake (1757–1827)
“The serial number of a human specimen is the face, that accidental and unrepeatable combination of features. It reflects neither character nor soul, nor what we call the self. The face is only the serial number of a specimen.”
—Milan Kundera (b. 1929)
“The last best hope of earth, two trillion dollars in debt, is spinning out of control, and all we can do is stare at a flickering cathode-ray tube as Ollie “answers” questions on TV while the press, resolutely irrelevant as ever, asks politicians if they have committed adultery. From V-J Day 1945 to this has been, my fellow countrymen, a perfect nightmare.”
—Gore Vidal (b. 1925)
“Time in the hand is not control of time,
Nor shattered fragments of an instrument
A proof against the wind; the wind will rise,
We can only close the shutters.”
—Adrienne Rich (b. 1929)
“The drama critic on your paper said my chablis-tinted hair was like a soft halo over wide set, inviting eyes, and my mouth, my mouth was a lush tunnel through which golden notes came.”
—Samuel Fuller (b. 1911)
