A prototype of a spacecraft planned as a 'lifeboat' for crews on the International Space Station passed a major milestone. The wingless X-38, the first new U.S. spacecraft developed in more than 20 years, successfully made its maiden unpiloted flight test. The nine-minute flight of the atmospheric test vehicle took place at NASA's Dryden Flight Research Center in California. The vehicle dove from the wing of a B-52 bomber at 23,000 ft. A series of parachutes slowed its descent. Then a 5,500-sq-ft parafoil--a steerable parachute--billowed out. The X-38 floated to a touchdown on its skids. The craft is the first of several increasingly detailed X-38s being built to test technology for a six-person "crew return vehicle." The X-38 has no engines. It uses the aerodynamic shape of the vehicle to provide the lift that airplanes get from their wings. In 2000, a space shuttle will carry a larger version of the X-38 into orbit. From there it is to plunge back to Earth for a practice landing.
At the Design News webinar on June 27, learn all about aluminum extrusion: designing the right shape so it costs the least, is simplest to manufacture, and best fits the application's structural requirements.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This radio show will show what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
