Pratt & Whitney's (P&W) newest engine, the F100-PW229A for F-15 and F-16 fighter aircraft, has demonstrated "unprecedented" performance in recent altitude tests, running at Mach 2.0. Under development for six years, the engine already has been tested to Mach 2.3 at 40,000 ft simulated altitude, and logged over 450 test hrs. The latest tests were to qualify production fan aerodynamics. "This is a fully configured engine under test, not one made up of components assembled for testing purposes," notes Dennis Enos, P&W's F100 program director. A key difference between this engine and other F100s that power operational F-15 and F-16 fighter aircraft is that it uses an advanced aerodynamic fan derived from F119 engine technology P&W developed for the F-22 Raptor. The robust design fan with its cast, one-piece inlet case exceeds air flow, efficiency, and stall margin requirements, Enos adds. P&W reports that the design represents the first military fighter engine not to require variable fan inlet geometry. FAX (407) .
The engineers and inventors of the post WWII period turned their attention to advancements in electronics, communication, and entertainment. Breakthrough inventions range from LEGOs and computer gaming to the integrated circuit and Ethernet -- a range of advancements that have little in common except they changed our lives.
Neil Fromer is the executive director of the Resnick Institute, a program for energy and sustainability at the California Institute of Technology, working to develop new ideas and research technologies related to providing a sustainable future. He spoke to us about the severity of the current drought in California and how solar energy can help prevent such situations in the future.
From home enthusiasts to workers on the manufacturing floor, everyone's imagination is captured by the potential of 3D printing.
