Looking more like a glider than an airplane, the two-seat, battery-powered eGenius made its first flight on May 25, from Mindelheim airfield in Bavaria, Germany. Designed by the Institute of Aircraft Design at the University of Stuttgart, the concept aircraft flew for 20 minutes powered by a 60kW electric motor.

On Monday at the Paris Air Show, HyperMach Aerospace Industries plans to unveil a “next generation” supersonic business jet (SSBJ) that can fly from Paris to New York in 1 hour 45 minutes.

The pair of “low-observable” Sikorsky Black Hawks used in the raid by U.S. forces against terrorist Osama bin Laden’s Pakistani compound May 2 were kitted with a variety of stealth and radar-defeating features that had been in development since the 1970s, and maybe longer. The helicopters came to light after one had to be left behind and intentionally detonated after apparently clipping a compound wall and making a hard landing.

The past couple of years have not been the best of times for a would-be developer to sign deals with industrial partners and customer-users for a new supersonic business jet (SSBJ), but Aerion has been hanging in there and is now seeking to make subsonic aircraft aerodynamically slicker.

A bilateral project between NASA and German aerospace research center DLR is expected to focus on the role rotor tip vortices play in helicopter noise by recording vortex velocity fields and rotor-blade deformations by using a test stand with a variety of high-speed cameras, lasers and LEDs that will make the vortices visible. Eventually research will progress to actual helicopters.

The innate intelligence of fly-by-wire (FBW) flight controls makes them a natural for reducing the relatively high pilot workload that can come with rotary wings.

The Pentagon’s Naval Research office has selected Emteq to create a rotorblade tip lighting system.

Dassault Aviation conducted a "successful" flight test to evaluate laminar wings for large business jets. The flight was performed at the companyπs flight-test center in Istres, France, using a Falcon 7X equipped with an infrared camera to measure differences in surface temperatures between laminar and turbulent areas of the horizontal tailplane.
