The new Airbus 380 may be the largest aircraft ever to be built, yet SKF engineers had devilishly tight constraints under which to design the bearing assembly for the horizontal tail stabilizer (HTP). The primary function of the HTP is to balance all the moments caused by the various aerodynamic and inertia forces and to provide a stable angle of incidence. A secondary function is to control the pitch of the aircraft. SKF engineers designed the failsafe hinge and shaft assembly that connects the horizontal fuselage and stabilizer and is a critical part of the HTP. To meet the loading (high) and weight (low), they employed a new, high-strength steel and titanium shaft and a bi-metal, spherical plain bearing designed to support loads up to 3,800 kN. The bearing's bronze inner ring allows a double rotation path. The plane is expected to enter service in 2005.
Enabling the Future is designing prosthetic appendages modeled more like superhero arms and hands than your average static artificial limbs. And they’re doing it through a website and grassroots movement inspired by two men’s design and creation in 2012 of a metal prosthetic for a child in South Africa.
In order to keep an enterprise truly safe from hackers, cyber security has to go all the way down to the device level. Icon Labs is making the point that security has to be built into device components.
Three days after NASA's MAVEN probe reached Mars, India's Mangalyaan probe went into orbit around the red planet. India's first interplanetary mission, and the first successful Mars probe launched by an Asian nation, has a total project cost of nearly $600 million less than MAVEN's.
