The new coating protects airplane engine components from heat damage, while lasting longer...

The higher the temperature at which an aircraft engine is able to run, the more efficiently it uses fuel. In order to run at those high temperatures, the metal components of airplane engines are presently treated with heat-shielding coatings. Scientists at Sweden's University West, however, are developing a new such coating that is said to be far more effective than anything presently used – it could extend the service life of engines by 300 percent.  Read More

Goodyear's new airship will enter service this northern summer

The Goodyear blimp may have been flying around for almost 90 years, but it still manages to turn heads. On Friday, there was another reason to look beyond nostalgia for the days of the great airships of old as Goodyear unveiled its new state-of-the-art blimp to the media, Goodyear associates and dealers at its Wingfoot Lake hangar in Suffield, Ohio. Built in partnership with the Zeppelin company, the new craft that replaces the 45-year old GZ-20 blimp fleet is not only larger and faster, it isn’t even a blimp, but a semi-rigid airship.  Read More

DARPA is working on revolutionizing rotorcraft technology

Helicopters and other rotorcraft are impressive bits of technology, but the only place where they match the performance of fixed-wing aircraft is in bad 1980s television. That may soon change with DARPA announcing the selection of four companies to compete in the next phase of its Vertical Take Off and Landing Experimental Plane (VTOL X-Plane) program. The four companies are tasked with developing unmanned demonstrator aircraft designed to increase the performance of VTOL rotor aircraft while reducing their complexity.  Read More

The Watchkeeper UAV has be given the go ahead for military flight tests (Photo: Richard Se...

Since first taking to the air in June 2009, trials of the UK's homegrown Watchkeeper tactical unmanned aerial vehicle have been conducted by industry partners including QinetiQ. The UK Ministry of Defence has now announced the aircraft has been awarded a Release To Service, clearing the way for flight training to begin with the Royal Artillery.  Read More

DARPA's ARES consists of a VTOL flight module capable of carrying several different types ...

Helicopters are an invaluable military resource for transporting supplies, carrying out surveillance and reconnaissance, and evacuating casualties from rugged terrain. Unfortunately, they are also a finite resource. That's why DARPA is looking to share the load with the Aerial Reconfigurable Embedded System (ARES) concept, a compact, high-speed and highly-automated delivery system with vertical take-off and landing (VTOL) capabilities.  Read More

Spike Aerospace has announced that its S-512 will feature a windowless cabin

Aircraft windows have always been a sticking point in the bid to go faster, cheaper and safer. As well as creating drag, the additional structural support and parts required for windows add weight to the plane. Spike Aerospace is set to overcome these problems by doing away with cabin windows altogether in its S-512 jet, and replacing them with video screens embedded in the interior walls.  Read More

The United Arab Emirates is set to deploy unmanned drones to deliver official government documents such as driving licenses and identity cards within a year, according to a report from Reuters.  Read More

The Scan Eagle UAV, and the Cessna that it knew not to fly into

In a recent flight test in Australia, a Scan Eagle UAV (unmanned aerial vehicle) succeeded in visually identifying an approaching Cessna aircraft, and letting its own ground-based operators know that evasive action was required. It's being hailed as a major step towards the allowance of UAVs in commercial airspace.  Read More

The Hubsan X4 FPV is likely the world's smallest quadcopter that can be flown by first-per...

It was just a few months ago that we showed you what is probably the world's smallest consumer quadcopter, the tiny Estes Proto X. Although it's a marvel of modern engineering, Gizmag writer Jonathan Fincher noted that it lacks any particularly interesting features, such as a camera. Well, late last year, Hubsan released its X4 H107D FPV. It's not much bigger than the Proto X, and it has a camera that transmits a real-time video signal to the user. When I heard about it, I knew I had to try it out.  Read More

FlexSys' variable geometry airfoil, the FlexFoil

If there's one thing that needs to be aerodynamic, it's an airplane wing. Conventional wing designs however, suffer from a glaring weakness in this respect: the joint where the main wing meets the trailing flaps. Michigan-based FlexSys has developed a way to optimize wing aerodynamics with FlexFoil, a seamless variable geometry airfoil system that could deliver fuel savings of up to 12 percent.  Read More
