Drive, float or fly? Your choice with the affordable Ramphos amphibious flying boat

August 1, 2007 With disposable income levels running high, expensive hobbies like aviation are coming within the reach of more and more people – and hobby pilots are discovering that small planes are coming down to a price point on a par with a touring motorcycle or midrange car. Owning a small plane has its drawbacks though – storing and transporting them can be difficult, not to mention the fact that you need an airstrip to take off and land from. The Italian Ramphos, however, suffers none of these issues. It’s an amphibious flying boat that’s just as happy taking off and landing on water as on land with its retractable wheels. You can tow it around on a trailer, and like the best of late-night TV exercise equipment, it folds for easy storage. This purpose-built little 2-seater is effortlessly easy to fly, handles like a dream and offers a very affordable, practical and exhilarating way to explore the local lakes and coastlines with maximum thrills for minimum fuss.

Passenger plane design set to evolve in the name of efficiency and emissions control

July 31, 2007 The standard aircraft design with which we have all become so familiar throughout the 20th century is headed for the scrap heap. Despite its ubiquitous nature, the traditional shape is set to be superseded in the push towards cleaner, greener aircraft that can transport people around the globe using less and less fuel. We wrote recently about Boeing’s Blended-Wing Body (BWB) aircraft, currently in testing – and now a new research group at a Netherlands university has been formed with the explicit goal of consigning the current shape of passenger airliners to the history books. The CleanEra project will investigate BWB, high-tech propeller engines and even UFO-style body shapes in their efforts to produce a light, efficient airliner model that produces less noise and cuts carbon dioxide emissions by at least 50% over current designs.

Electric sports plane the highlight of the e-flight initiative

By Loz Blain

July 30, 2007 With rising oil prices threatening to put sports aviation out of reach of the average enthusiast, innovators are looking at how the sport might be preserved for the next generation. Sonex and Aeroconversions are two such innovators and in partnership the two companies unveiled their three-prong e-Flight strategy at the recent AirVenture OshKosh trade show. An ethanol conversion of Aeroconversions’ AeroVee powerplant and efficiency enhancements for the engine took a back seat to the prototype electric Waiex aircraft introduced to an appreciative crowd. With battery technologies advancing by the day - gaining power, reliability, endurance and efficiency while constantly shedding size and weight - the partners believe the time is ripe to adapt the brushless Read More

Blended-Wing Boeing completes first test flight

By Loz Blain

July 30, 2007 The traditional airplane shape is well tried and tested, but manufacturers like Boeing are moving beyond the "tube with wings and a tail" design in the push to improve fuel economy and the environmental impact for the next generation of jets. Inspired by "flying wing" designs from earlier decades like 1988's B-2 Stealth bomber, the company has been collaborating with NASA to test the viability of a Blended Wing Body (BWB) aircraft, using a flat, wide body that tapers out to thin wing-tips and aims to strike an effective middle ground between the tube and flying wing designs. A BWB design allows the entire body of the plane to generate lift and reduces drag in comparison to a tube-shaped fuselage - both of which are key factors in reducing fuel usage. The BWB design also provides a much greater cargo and passenger capacity - making it particularly attractive to the military. After months of development, ground testing and wind-tunnel testing, Boeing flew its first BWB prototype last week with the 8.5 per cent scale, 500-pound X-48B aircraft reaching 7500 feet before a successful landing under remote control.

B-2 Bomber with Massive Penetrator weapon

By Gizmag Team

July 23, 2007 Just how important does someone have to be to have their own 30,000 pound bomb delivered by a billion dollar aircraft? We'll soon know. We have written about the Massive Penetrator weapon before here and detailed the awesome firepower and effectively infinite range of the US$1.157 billion B-2 here. The B-2 is a multi-role bomber capable of delivering both conventional and nuclear munitions through previously impenetrable defenses. The B-2’s low-observable technologies with high aerodynamic efficiency, large payload and an unrefueled range of approximately 6,000 nautical miles (9,600 kilometers) give it the unique ability to penetrate an enemy's most sophisticated defenses and threaten its most valued, and heavily defended, targets.

Wind detection technology improves airport safety

By Noel McKeegan

June 21, 2007 A new wind detection system installed at Tokyo International Airport will provide air traffic control personnel with improved monitoring of wind activity and advanced warning of hazards such as low-level wind shear. The WindTracer system developed by Lockheed Martin is a Doppler LiDAR (light detection and ranging) system that provides high-resolution wind data and mapping at a range of up to six nautical miles.

Superconductor research points towards feasible electric airplanes

By Loz Blain

June 19, 2007 With combustion-driven aircraft currently producing around 5% of greenhouse gas emissions, the time has clearly come to look at alternative power sources across the skyways. Electric motors have come a long way in relation to cars, but American scientists have now unveiled research that would enable high-powered, ultra-reliable electromagnetic engines to be built for airplanes. Using lightweight superconductors and emission-free hydrogen fuel cells to get around the problems experienced by previous attempts, these electric planes would be eco-friendly, exceptionally quiet and highly energy efficient as well as dramatically cutting down on maintenance costs through the elimination of engine hydraulics. This is an exciting convergence of technology with amazing implications throughout the transport sector. Read More

New Medium Altitude Endurance UAV to deliver better real-time reconnaissance to soldiers in urban battle zones

By Mike Hanlon

February 2, 2005 - Northrop Grumman has successfully completed the first phase of flight testing a demonstrator version of a new medium altitude endurance unmanned aerial vehicle (UAV). Soldiers in urban battle zones could receive more timely and complete information about enemy forces from low-flying unmanned aerial vehicles (UAV) with the technologies being developed. Read More
