Edwards AFB, CA —The clock is counting down for selection of a design for the U.S. Joint Strike Fighter (JSF) later this year (see DN 2/17/1997).
Boeing's X-32A JSF demonstrator recently completed its flight test program which included simulated aircraft carrier landings.
Boeing's demonstrator for the land- and carrier-based versions, the X-32A, recently completed flight tests which included: low-speed aircraft carrier approach tests; aerial refueling; supersonic flight; and side-mounted weapons bay vibration and acoustic tests. The short takeoff and vertical landing (STOVL) prototype (X-32B), featuring redirected engine fan and exhaust flows like the existing Harrier, was scheduled to fly by the end of March.
Lockheed Martin's X-35C, its carrier-capable demonstrator which features an enlarged wing, is now at the Patuxent River test center for the Navy for continued carrier testing. The conventional takeoff version (X-35A) for the Air Force completed its test program late last year and is being outfitted with an engine-driven lift fan for STOVL flight testing as the X-35B. These flights should start by late spring.
What makes this movie stand out from the typical high school sports story is that the teenagers are undocumented immigrants, and the big game is a NASA-sponsored marine robotics competition. Like many other Hollywood movies, however, Spare Parts only tells part of the story. What the film shows -- and doesn’t show -- raises important issues affecting STEM education in the US.
Instead of sifting through huge amounts of technical data looking for answers to assembly problems, engineers can now benefit from 3M's new initiative -- 3M Assembly Solutions. The company has organized its wealth of adhesive and tape solutions into six typical application areas, making it easier to find the best products to solve their real-world assembly and bonding problems.
Load dump occurs when a discharged battery is disconnected while the alternator is generating current and other loads remain on the alternator circuit. If left alone, the electrical spikes and transients will be transmitted along the power line, leading to malfunctions in individual electronics/sensors or permanent damage to the vehicle’s electronic system. Bottom line: An uncontrolled load dump threatens the overall safety and reliability of the vehicle.
