Engineers at the Army Research Laboratory are exploring the use of carbon nanotubes to make helicopter blades perform better. Nanotubes have been shown to dissipate energy when embedded in small ...

China's new helicopter with its coaxial main rotors and pusher propeller looks almost identical to the U.S.-made Sikorsky S-97 Raider.

The blades of a helicopter in flight are subject to tremendous forces. A scratch can become the focal point of high-energy stresses and trigger a catastrophic failure, Small said.

The technology has established a digital coordination system for the helicopter nacelle manufacturing. It reduces the standard tooling and tooling coordination. It realizes the rapid optimization ...

The image shows NASA's Ingenuity Mars helicopter stranded on the desert terrain, with its rotor blade scattered several dozen feet away.

Night Hunters and Alligators: Russian military helicopters The new blades reduce negative aerodynamic effects arising for helicopters of the classical design at high speeds, the chief executive added.

The coaxial design, with rotors spinning in opposite directions, coupled with special software counters the tendency of helicopter blades to generate uneven lift and turbulence at high speeds.

U.S. Air Force funds effort to improve composite rotor blade design analysis capabilities for AAM AnalySwift partners with Weber State, BYU, UAMMI and Hexcel for materials research, qualification and ...

Ingenuity's broken helicopter blade has been spotted on Mars. The little chopper made a hard landing on Jan. 18 and is grounded forever.
