It can also run at subsonic test conditions in aerodynamic and propulsion cycles. The 10×10 can be run in aerodynamic (closed-loop) cycle or propulsion (open-loop) cycle. The 10×10 is equipped to accommodate large-scale aerodynamic (force and moment) models and full-scale engine and aircraft components.The 10×10 is specifically designed to test supersonic propulsion components such as inlets and nozzles, propulsion system integration, and full-scale jet and rocket engines.The 10×10 facility is the largest and fastest wind tunnel at NASA Glenn.When coupled with NASA Glenn’s 8- by 8-Foot Supersonic Wind Tunnel (8×6), the 10×10 provides aerodynamic and propulsion test capabilities from low subsonic through high supersonic Mach range.Variety of available research test hardwareįor further technical information about the facility, please refer to the capabilities page within this site.Schlieren and advanced optical imagery (infrared, sheet lasers, LDV-Laser Doppler Velocimetry, PSP-Pressure Sensitive Paint, TSP-Temperature Sensitive Paint).Specialized support systems and equipment include: Real time transmission and display of all test data and information can be provided to customer locations outside of NASA Glenn. To increase test productivity, a test matrix sequencer automatically changes model variables by using a pre-programmed test matrix. An optical instrumentation suite of capabilities is also used depending on test requirements. Steady state and dynamic data is collected from the model instrumentation, processed, and displayed in engineering units and graphical formats. The facility is controlled and operated by a digital distributed control system in order to maximize data quality while minimizing operational costs. Dry air is added to maintain test conditions. During the aerodynamic cycle, the tunnel runs as a variable density facility that can simulate pressure altitude conditions ranging from 50,000 to 154,000 feet. This mode is used for models that introduce contaminants into the air stream or use potentially explosive gas mixtures or when the tunnel air-heater is used to simulate flight temperatures. In the propulsion cycle, the tunnel operates by continuously drawing outside air through a very large air dryer to remove the moisture and exhausting it back into the outside environment. The crew of Captain America tours the 10- by 10-Foot Supersonic Wind Tunnel (10×10). There is also continuous operation across the entire speed and altitude regime, offering users greater flexibility and productivity during testing. Gust and Mach plates are sometimes installed to expand local Mach number conditions between Mach 1.5 and 4.1. It can operate as a closed-loop system (aerodynamic cycle) or open-loop system (propulsion cycle), reaching test section speeds of Mach 2.0 to 3.5 and very low speeds from 0 to Mach 0.36. The 10×10 was specifically designed to test supersonic propulsion components such as inlets and nozzles, propulsion system integration, and full-scale jet and rocket engines. The test section is 10 ft high by 10 ft wide by 40 ft long and can accommodate large-scale models, full-scale engines and aircraft components. Throughout its history, the tunnel has made valuable contributions to the advancement of fundamental supersonic propulsion technology, the development of Atlas-Centaur, Saturn and Atlas-Agena class launch vehicles, and vehicle-focused research programs including the High-Speed Civil Transport, the National Aerospace Plane, and the Joint Strike Fighter. He named the Apollo program and laid the groundwork for that program’s success in landing a man on the Moon. Silverstein was responsible for the Mercury program, and for all unmanned satellite programs for the first three years of the agency. Abe Silverstein and Eugene Wasliewski, the 10×10 was brought on line. The Unitary Plan Act, passed by Congress in 1949, was a coordinated national plan of facility construction that encompassed the National Advisory Committee for Aeronautics (NACA), Air Force, industry, and universities.
