the mid-air collision over Charkhi Dadri near Delhi might not have taken place if the Saudia and Kazakhstan Airlines had been using a Traffic Alert Collision Avoidance System (tcas). tcas or Airborne Collision Avoidance System (acas) is the air-to-air communication system that issues audio-visual warnings to the pilots whenever two …
autogyros that had vanished from the scene after a brief period of popularity in 1930s, may soon stage a comeback. Autogyros are the fly machines that can carry up to five persons at a time. The gyroplanes
a new airport system being used at Altanta Hartsfield International, is helping passengers miss fewer connections and wait less time for flights. The system has been jointly developed by the us -based National Aeronautics and Space Administration (nasa) and the Federal Aviation Administration (faa). The system known as the Surface …
engineers could soon be able to produce all-electric aeroplanes with the help of a new device. The device called the Electro-Hydrostatic Actuator has been developed by engineers at the National Aeronautics and Space Administration ( nasa ) Dryden Flight Research Center, Edwards, usa . These planes would be safer and …
Passenger aircraft in the future may fly without wind screens for pilots to peer through. The National Aeronautics and Space Administration (NASA) has been experimenting with a wind screen-less cockpit they may find application on the second generation supersonic airliner. The NASA has developed a scale model of a fighter …
airships seem to have the potential of offering a good alternative to aeroplanes and road vehicles in some segments of the passenger transport market, say researchers in the Netherlands. Airships are dirigible-powered balloons and derive their lift from a gas (usually helium) that is lighter than air. The airship's body …
scientists are employing various techniques to develop metal foams that are sound and heat absorbent, lightweight and fireproof. These unique properties of the foams could soon attract wide-ranging applications in manufacturing cars, ships and aeroplanes. Metal foams are made up of metals such as aluminium and require less material to …
british researchers have developed floating devices that would help prevent helicopters from capsizing. The floating devices are fitted at the top of the cabin of the aircraft and are less likely to be damaged by the impact generated after it crashes into the sea ( New Scientist , Vol 155, …
An open-cockpit, single-seater helicopter has been developed jointly by Rhyme Co of Tokyo and Engineering System Co of Nagano Prefecture, Japan. The helicopter is priced at US $20,000. No licence is required for flying the helicopter because it is not classified as an aircraft. With a pilot weighing 60 kg, …
the difference between business-class and economy-class tickets could be more than the money for some. The lack of leg-room in economy-class can lead to the development of blood clots in the legs known as deep-vein thrombosis ( dvt ) in middle-aged passengers, says Kevin Burnand, head of surgery at Guy's …
the us Air Force is developing an Active Aeroelastic Wing ( aaw ) that may bring a lasting impact on the aircraft industry by making jet fighters and supersonic passenger planes cheaper. The smart wing is being developed at Wright-Patterson Labora-tory, Ohio, usa. It can change shape to suit the …
A four-seater plane has been developed in the UK that can take off from a 3,000-ft runway and cruise for 2,415 km at approximately 800 km per hour. This tiny jet, called CMC Leopard, weighs 1,812 kg
A fibre-reinforced plastic bolt has been developed in Australia that is stronger than steel. The bolt has been designed for use such as a stabiliser for roofs and walls in underground tunnels. It can also be used in the aerospace industry. It is very expensive to install plastic products in …
After years of false starts and setbacks, the hybrid of a plane and a helicopter, known as a tiltrotor, is all set for commercial operations. Bell Helicopter Textron and the Boeing Company's helicopter division have come out with Bell-Boeing 609, a nine-passenger commercial tiltrotor. It has two sets of rotors …
A thin polymer film with a pressure-sensitive adhesive would be used as a coating for US fighter planes. This is meant to replace the conventional paint which adds to the weight of the aircraft. Developed jointly by Boeing and 3M, the film, called appliqu
Spyplancs, small enough to fit into a palm, may take off within three years. Microflyers, as they are called, will have a wingspan of about 15 cin and would weigh less than 100 gin. The planes are being developed by researchers at the Georgia Institute of Technology, Atlanta, US, who …
A PILOTLESS aircraft, that should be able to stay in the air for weeks, circling the globe to monitor the state of the earth's atmosphere and to keep an eye on pollution levels is being developed by the National Aeronautics and Space Administration (NASA). Pathfinder, as it is galled, is …
A spy plane that can scrutinise a country the size of Switzerland in two days from an attitude of 19,760m has been unveiled by the US Defence Department. Pentagon chiefs say it is likely to be used above the reach of enemy craft to guide a low-attitude unmanned spy plane, …
A gyroplane (a flying machine balanced and supported by rapidly rotating horizontal or slightly inclined blades) said to be capable of flying non-stop around the world at 800 kmph has been developed in the US. Texas-based Jay Carter says his Cartercopter, fitted with two rotors and a modified racing- car …
Technology that could reduce the amount of time taken to manufacture an aircraft by at least 20 per cent is being assessed by aerospace groups around the world. The companies hoping to cut years from design schedules include India's Hindustan Aeronautics Ltd, British Aerospace, France's Airbus Industries and Indonesia's Industri …
