Bell's revolutionary X-plane rotorcraft has received the green light to progress to the building and testing of a demonstrator aircraft. DARPA has down-selected the craft to move to Phase 2 of the ...

For laser science, one major goal is to achieve full control over the spatial, temporal, and polarization properties of light, and to learn how to precisely manipulate these properties. One property ...

Bell Textron has completed wind tunnel testing for its rotor-folding aircraft as part of the Defense Advanced Research Projects Agency (DARPA) Speed and Runway Independent Technology (SPRINT) program.

Tilt rotors look like the perfect military cheat code - take off like a helicopter, fly like a plane, and strike farther than anyone expects. That speed and range can change an entire mission before ...

Part of the charm of quadcopters is the challenge that building and flying them presents. In need of complex sensors and computational power to just get off the ground and under tremendous stresses ...
