The Marine Corps (www.usmc.mil)
knew about a design flaw in the Osprey hybrid helicopter-airplane before it
caused two fatal crashes in the past year, say unnamed Marine Corps pilots who
were investigating the incidents.
Osprey crashes last December (in North Carolina) and April (in
Arizona) have killed a total of 23 Marines in 2000. There were also seven killed
in a crash in 1992, and a nonfatal crash in 1991.
The Marine pilots announced yesterday that the Pentagon (www.defenselink.mil) knew about a flaw in
the hydraulic system that was compounded by a software glitch, but were
reluctant to address the problem because they thought it would risk federal
funding for the plane.
Marine investigators have long suspected that the hydraulic system
was to blame, but they did not know that senior Marine officers already knew
about the problem.
At stake is an order of 360 of the MV-22 tilt-rotor planes, which
are built jointly by Boeing (www.boeing.com/rotorcraft/) and
Textron's Bell Helicopter Div. (www.textron.com/businesses/aircraft/profile.html).
The aircraft can take off vertically like a helicopter and then rotate its two
propellers to fly like a normal airplane.
By refining topologies and using new fluid technology, Moog's new peak sine drive controller increases available power without increasing controller volume.
Lantronix Inc. has expanded its line of controllers for sensor networks with the release of a rugged controller that improves management of automation systems used in a number of industries, including manufacturing, oil and gas, and chemicals.
Inspired by the hooks a parasitic worm uses to penetrate its host's intestines, the Karp Lab has invented a flexible adhesive patch covered with microneedles that adheres well to wet, soft tissues, but doesn't cause damage when removed.

A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
