1×1 Supersonic Wind Tunnel

The 1- by 1-Foot Supersonic Wind Tunnel (1×1) 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

Exhaust Nozzle Plume Effects on Sonic Boom Hardware

The 1×1, located in the Engine Research Building (ERB), is one of the most active test facilities at  NASA’s Glenn Research Center in Cleveland. This facility is used to conduct fundamental research in supersonic and hypersonic fluid mechanics, supersonic-vehicle-focused research and detailed benchmark quality experiments for CFD code validation.

The tunnel can provide continuous operation at 10 discrete airspeeds from Mach 1.3 to 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 uses several different types of experimental research tools that are invaluable to fundamental studies.

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

The equipment in the 1×1 is complemented by 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 offers the supersonic research community an excellent low-cost tool for fundamental small-scale research.
