Langley's 8-Foot Transonic Pressure Tunnel (TPT) was completed in (on the former site of the Propeller Research Tunnel). The tunnel was capable of operating at pressures between and atmospheres, and had sophisticated air temperature and humidity controls. Foot Transonic Tunnel The Langley Foot Transonic Tunnel (Ft TT) is an atmospheric, closed-circuit tunnel with a Mach number range of to and a Reynolds number range from 1 x 10 6 to 4 x 10 per foot.
The test section of the tunnel is octagonal with a. Pressure Sensitive Paint (PSP): PSP is a technique whereby a model is spray coated with a paint that reacts to variations in pressure by changing color.
In conjunction with this technique, cameras are usually positioned at strategic viewing angles through the walls, ceiling, and floor of the wind tunnel to photograph the model while the wind is on. pressure.1 Temperature sensitive paint (TSP) similarly responds to a change in temperature.
PSP/TSP have been used at Langley in various wind tunnels since the ’s. 2 A complement of hardware, software, and operational procedures used by the Global Surface Measurements Team over. Report describes the development of the Langley annular transonic tunnel, a facility in which test Mach numbers from to slightly over are achieved by rotating the test model in an annular passage between two concentric cylinders.
Data obtained for two-dimensional airfoil models in the Langley annular transonic tunnel at subsonic and sonic speeds are shown to be in reasonable agreement.

The investigation, conducted over a 6-week period, provided force and moment, surface pressure, model deformation, and surface flow visualization data.
Testing was conducted at 5, and 30 million Reynolds number. One of the two foot-diameter fans in the Foot Transonic Tunnel at Langley Research Center. The second fan is partially visible in the background. Note the Sitka spruce blades, which were used in many wind tunnels. Image Number: L Date: Ma Views: K.
Performance Automotive Applications of Pressure-Sensitive Paint in the Langley Full Scale Tunnel Recently, there has been a strong emphasis on aerodynamic and aeroacoustic wind tunnel testing of automobiles.

In: Proceedings of the 14th ISFV, ISFVD-5; Ota T. A separated and reattached flow on a blunt flat plate. J Fluids Eng. ; 98 (1)– doi: / All experiments were conducted in the m transonic cryogenic tunnel ( m TCT) located at NASA Langley Research Center in Hampton, VA.
This facility is a fan-driven, closed-loop wind tunnel capable of operating with a number of different test gases including air, nitrogen (N 2), and sulfur hexafluoride (SF 6) .For these tests, only N 2 was used, which is required for the highest-Reynolds.
Subsonic tunnel. Low-speed wind tunnels are used for operations at very low Mach number, with speeds in the test section up to km/h (~ m/s, M = ) (Barlow, Rae, Pope; ). They may be of open-return type (also known as the Eiffel type, see figure), or closed-return flow (also known as the Prandtl type, see figure) with air moved by a propulsion system usually consisting of large.
A Comparison of Pressure Sensitive Paint (PSP) Techniques for Aerodynamic Testing at Slow Velocities Pressure Sensitive Paint (PSP) has been used for several years by the aircraft industry in transonic wind tunnel testing where the oxygen concentrations are low and the luminescence of the paint is easily recorded.
Pressure and Temperature Sensitive Paints Tianshu Liu, John P. Sullivan Luminescent molecule sensors, called pressure-sensitive paint (PSP) and temperature-sensitive paint (TSP), measure factors essential for understanding the aerodynamic performance and.
