Airplanes back into theJet engines ingest a lot of air, and tests dont go well with U-shaped structure so exhaust from theirtailwinds, Anzai comments.engines is directed at the curved rear wall,The likelihood of a crosswind spoiling test conditions is which essentially renders potentially dangerousminimized with strategically located vents on the two sidewalls. The engine thrust less hazardous by deflecting itvents create a headwind inside the structure, no matter which way skyward, explains Anzai. the wind is blowing outside. Naturally, the number of vents needed Some GREs are acoustically treated tovaries from airfield to airfield. Its a function of aerodynamic needs, absorb and reduce noise as well, but thatMATT ANZAI Anzai says. wasnt the case at OSC because its in a rural area with no nearbyKalittas structure at OSC has more than 200 sidewall vents, and residences.one large vent on the rear wall. The tops of the walls are rounded Aerodynamic Design to further reduce turbulence. The design of a GRE begins with an analysis of prevailing wind speedsWith just three walls, it doesnt look very complex, Vette says. and direction, which helps determine an optimal location. At OSC, thatBut theres way more to the facility than meets the eye. Its much turned out to be on the east side of the airfield, facing west. more than just three walls.The height and size of a GRE are guided by the size of aircraftNo matter how well designed a GRE is, there still are times when that will use it, and whether or not noise attenuation is required.it cant be used because of wind conditions. Vette estimates that The structure at OSC occupies about two acres of land (leased toKalittas structure at OSC is usable about 85% of the time. This Kalitta by the airport) and measures 268 feet wide at the front, 198provides much more availability than before, when technicians feet wide at the back and 315 feet deep.could only run tests when there was a headwind coming from the right direction.Because technicians need optimum testing conditions, GREs are designed to facilitate the movement of smooth, turbulence-free airIn total, Blast Deflectors Inc. has designed 21 GREs for North into the engines.
