Advanced control technology resurrects idea for lighter wings

Article Abstract:

Active Aeroelastic Wings (AAW) represents a re-birth of the 'wing warping' used by the Wright brothers to control the roll and bank of their first aeroplanes, but with addition of advanced control. Flexible, warpable wings are potentially lighter than stiff wings with flaps and actuators to move them, and this version is developed by NASA's Dryden Research Center in Edwards, California using a modified F/A-18A obtained from the US Navy.

Flat disks make ultimate spring

Article Abstract:

A revolutionary technology where a pair of titanium disks pressed together by shallow domes could well be the ultimate spring for heavy duty brakes or clutches is presented. Skeptics however are still not convinced that titanium spring pistons can be used for four wheelers and motorcycles but the company is going full steam ahead with further experiments and developments.

Golden chain thrusts into actuation

Article Abstract:

A device invented by Danish developers called 'Kataka', a Sanskrit name for golden chain, is developed that could revolutionise linear actuation in a very wide range of industries and products. The characteristics, various applications and technical aspects of the device are discussed.
