1’ x 1’ Supersonic Wind Tunnel

The 1- by 1-foot Supersonic Wind Tunnel (SWT) specializes in conducting fundamental research in supersonic and hypersonic fluid mechanics, supersonic-vehicle-focused research and detailed benchmark quality experiments for Computational Fluid Dynamics (CFD) code validation.

Facility Overview

Low Boom Glenn Research Center Advanced Nozzle Concepts, Exhaust Nozzle Plume Effects on Sonic Boom Hardware in 1’x1′ Supersonic Wind Tunnel.

The 1′ x 1′ Supersonic Wind Tunnel (1×1), located in the Engine Research Building (ERB), is one of the most active test facilities at the NASA Glenn Research Center. Used to conduct fundamental research in supersonic and hypersonic fluid mechanics, it is also used for supersonic-vehicle-focused research and detailed benchmark quality experiments for CFD code validation.

The tunnel can provide continuous operation at 10 discrete airspeeds between Mach 1.3 and 6.0 by using an appropriate fixed-area contoured nozzle block upstream of the test section.

A number of specialized support systems are available to meet the research customer’s needs such as auxiliary bleed, model hydraulics, and probe actuation systems. Model buildup and machine shop equipment also are available to accommodate model changes. The 1×1 SWT uses several different types of experimental research tools that are invaluable to fundamental studies.

Flow can be visualized with the use of schlieren, a sheet-laser system, or blue Zyglo and black lights. Qualitative flow-field measurements can be made with a two-component laser Doppler velocimeter (LDV) and trace gas systems.

The equipment in the 1×1 SWT is complemented by a staff experienced in supersonic test hardware and experimentation. Two-shift staffing and operation provide high productivity, flexibility, and quick model installation and configuration changes. With its capabilities, expert staff, and efficiency, the 1×1 SWT offers the supersonic research community an excellent low-cost tool for fundamental small-scale research.
