      Tunnels Such as the LaRC 14x22 Wind Tunnel Test Technology Support Such as Force and Moment Test Techniques 4 Capability Advancement Support Such as the “Optical Test Section of Tomorrow” at the Ames Unitary Plan Wind Tunnel. was designed to be compatible with optical instrumentation techniques. The inaugural tests of the CRM were conducted in the National Transonic Facility at the NASA Langley Research Center and the 11ft transonic leg of the Unitary Plan Wind Tunnel at the NASA Ames Research Center. The test in the National Transonic Facility2 (NTF) focused on aero.

    The objective of this paper is to compare the current state-of-the-art of the following three optical techniques under study by NASA for measuring model deformation in wind tunnels: (1) video. The 8-by-8 foot segment of the tunnel opened for operation in , it began construction in as a result of the Unitary Wind Tunnel Plan Act of passed by the United States Congress. The Ames facility played a heavy role in the United States space program performing aerodynamic testing on the Mercury, Gemini, and Apollo spacecrafts and.

      This book presents current research in the study of wind tunnels, including the design, execution and numerical rebuilding of a plasma wind tunnel with the aim to analyse shock wave boundary layer interaction phenomena; the Mainz vertical wind tunnel facility experimenting on cloud physics and chemistry; an air-conditioned wind tunnel environment for the study of mass and heat flux; using wind. The TSoT project is a presidential budget line item to advance flow visualization and optical access in the Ames Unitary Plan WInd Tunnels.

Several of the optical sensors can meet the requirements of the Ames Unitary Plan Wind Tunnel. Two of these, the Boeing interferometer, and the Complere lateral effect photodiode sensors are being developed for the Ames Unitary Plan Wind Tunnel.

During the past 10 to 15 years, there has been a large effort to design fuel efficient airplanes. wind tunnel optical techniques, some conceptual designs, and recommendations for use of optical methods in the Ames Unitary Plan Wind Tunnels. Particular emphasis was placed on searching for systems developed for wind tunnel use and on commercial systems which could be readily adapted for wind tunnels.

The six parts of the study have been reported as MCAT Institute reports under. Study of optical techniques for the Ames unitary wind tunnels. Part 1: Schlieren. By George Lee. Abstract. Alignment procedures and conceptual designs for the rapid alignment of the Ames Unitary Wind Tunnel schlieren systems were devised.

The schlieren systems can be aligned by translating the light source, the mirrors, and the knife edge. A summary of optical techniques for the Ames Unitary Plan wind tunnels are discussed. Six optical techniques were studied: Schlieren, light sheet and laser vapor screen, angle of attack, model deformation, infrared imagery, and digital image processing.
