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.
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.
The age of touch could soon come to an end. From smartphones and smartwatches, to home devices, to in-car infotainment systems, touch is no longer the primary user interface. Technology market leaders are driving a migration from touch to voice as a user interface.
Soft starter technology has become a way to mitigate startup stressors by moderating a motor’s voltage supply during the machine start-up phase, slowly ramping it up and effectively adjusting the machine’s load behavior to protect mechanical components.
A new report from the National Institute of Standards and Technology (NIST) makes a start on developing control schemes, process measurements, and modeling and simulation methods for powder bed fusion additive manufacturing.
If you’re developing a product with lots of sensors and no access to the power grid, then you’ll want to take note of a Design News Continuing Education Center class, “Designing Low Power Systems Using Battery and Energy Harvesting Energy Sources."
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
