Flying Robot Mimics Rapid Insect Flight

Flying animals both power and control flight by flapping their wings. This enables small natural flyers such as insects to hover close to a flower but also to rapidly escape danger. Animal flight has...

New Airplane Wing Assembled from Tiny Identical Pieces

A radically new kind of airplane wing, assembled from hundreds of tiny identical pieces, can change shape to control the plane’s flight, and could provide a significant boost in...

Advanced Over-the-Wing Nacelle Transport Configuration

NASA’s Langley Research Center has developed a new aircraft design with the engine nacelle over the wing, improving engine ground clearance and freeing landing gear design. While...

X-Ray Study of Low-Density Materials

It's hard to get an X-ray image of low-density material like tissue between bones because X-rays just pass right through like sunlight through a window. Sandia studies myriads of low-density materials,...

Material Removes Ice Buildup Without Power or Chemicals

From airplane wings, to overhead power lines, to the giant blades of wind turbines, a buildup of ice can cause problems ranging from impaired performance all the way to catastrophic...

Spanwise Adaptive Wing

NASA's Glenn Research Center developed a novel means of articulating the outboard portion of an aircraft wing to create the optimal geometry for given flight conditions. The Spanwise Adaptive Wing (SAW) concept employs...

Wing Shape Design Reduces Vortex and Wake

It's common to see line-shaped clouds in the sky, known as contrails, trailing behind the engines of a jet airplane. What's not always visible is a vortex coming off of the tip of each wing — like...

Variable-Camber Compliant Wing

In the early years of manned flight, wing warping was used for lateral control of an aircraft. This technique consisted of a system of pulleys and cables used to twist the trailing edges of the wings in...
