Arnold Improves Engine Testing
|
|
 Testing completed in March at the Air Force Arnold Engineering Development Center will help validate proposed improvements to the Pratt & Whitney F100-220 engine and prepare it for flight testing. During the eighteen-month AEDC test phase, technicians tested the increased blade stiffness, oil seals, and improved logic control systems of the engine. A laser beam trained on the engine compressor measured the amount of blade deflection or bending occurring when the engine operated at selected flight conditions. This new measurement system, which allows every blade to be measured at various angles, replaces the previous method of placing strain gauges randomly on a few of the blades. |
