Faster Than a Speeding Bullet: Guinness Recognizes NASA Scramjet 2007-05-04 22:03:00 NASA has been officially recognized for setting the speed record for a jet-powered aircraft by Guinness
World Records.NASA set the record ,during the third and final flight of the experimental X-43A scramjet (supersonic-combustion ramjet) project. The X-43A demonstrated an advanced form of air-breathing jet engine could power an aircraft nearly 10 times the speed of sound. Data from the unpiloted, 12-foot-long research vehicle show its revolutionary engine worked successfully at Mach 9.6 (approximately 7,000 mph), as it flew over the Pacific Ocean west of California.The flight was the culmination of NASA's Hyper-X Program. Hyper-X, a seven-year, approximately $230 million ground and flight test program, explored alternatives to rocket power for space access vehicles.This is the second world speed record earned by the Hyper-X Program. The first followed a Mach 6.8 (approximately 5,000 mph) flight in March 2004. Both records will be featured in the 2006 edition of the Guinness World Rec Read more:Speeding

India to buy Hercules from US Air Force 2007-05-04 21:01:00 Indian Air Defence is planning to purchase a C-130J, otherwise called Hercules
.This Lockheed Martin C-130 is manufactured by US air force.Typically used for tactical cargo and military personnel transport.The latest model of this is called C-130J Hercules with a glass cockpit with digital avionics integrated with new propulsion system having six bladed propeller. Hercules is basically a four-engine turboprop aircraft and have 40 different variant successfully used in 67 odd nations worldwide.C-130 has been used since 1954 and almost 2500 Hercules are built worldwide.The new C-130J have enhanced range,cruise ceiling time to climb and speed.Also the 'J' model good performance in hot and high conditions can increase the performance of similar aircraft by 50-70%. The cargo bay of the C-130J has a total usable volume of over 4,500ft. The C-130J is equipped with four Allison AE2100D3 turboprop engines, each rated at 4,591 shaft horsepower (3,425kW). The all-composite six-blade R391 prope Read more:India

Silent Aircraft Initiative 2007-04-25 21:37:00 The Silent
Aircraft Initiative is a study being undertaken by the Cambridge-MIT Institute to discover ways to reduce aircraft noise dramatically, to the point where it would be virtually unnoticeable to people outside the airport perimeter.Launched in November 2003, the program has the support of Rolls-Royce, Boeing and Marshall Aerospace.Part of the study is examining if a steeper continuous descent into an airport will reduce approach noise levels. Theoretical analysis will be backed-up by field trials using real jetliners.A major part of the study is developing jetliner/engine designs that can meet the SAI objectives. The favoured configuration is a blended wing design, with the engines located on the upper surface of the wing, to shield ground observers from the engine noise. A very low specific thrust (i.e. very high bypass ratio) turbofan is proposed for the aircraft. Engine handling and low jet noise are facilitated by the use of a variable area final nozzle, to rematch the fan
GEN H-4 2006-11-23 06:45:00 Ok, "This is one of the strangest things I've seen on the net today!" you are probably thinking to yourself, but what is it you ask? It's the "GEN H-4." The world's smallest co-axial helicopter ever made! This is a Japanese designed and manufactured ultralight one-man helicopter. The total empty weight of this helicopter is only 155 lb.Yes, you're right it is a quite interesting contraption! It is true that there is not much to see on the outside. The frame is 2 inch aluminum pipe bent and welded, with a fiberglass backpack and funny looking wheels. The controls are direct, like many gyrocopters. In front of the pilot attached to the control bar is the control panel with the throttle (altitude control), tachometer, ignition power, starter and yaw switches. The tools necessary for flight do not seem like much because they aren't. This is not only the lightest helicopter in the world, but it is the

is exploring a creative way to utilize gravity as a power source to produce an aircraft concept which might one day take people and cargo great distances without the need for fuel. The project is called the GravityPlane.The idea sprung from the brain of Robert D. Hunt, a theoretical physicist. It uses a cycle of climbing and descending to maintain its lift and forward speed, mimicking the behavior of the bodies of warm and cold air which make up the weather. For the GravityPlane to become airborne, gas bags inside a pair of rigid, zeppelin-like structures are filled with helium from storage tanks inside the vehicle. Overall weight by releasing the stored air which acts as ballast. Once the craft reaches the altitude where the helium is no longer lighter than the surrounding air– theoretically as high as ten miles up– it is unable to climb any further. Some of the stored compressed air is then expanded into the dirigible areas, decreasing the buoyanc
FUTURE MOBIL 2006-10-17 12:51:00 During the 1950s, much of the world was quivering with anticipation over the exciting prospects of nuclear power. It seemed that there was no energy problem too large or too small for the mighty atom to tackle during the glorious and modern Atomic Age.It was during this period in 1957 that the Ford Motor Company unveiled the most ambitious project in their history: a concept vehicle which had a sleek futuristic look, emitted no harmful vapors, and offered incredible fuel mileage far beyond that of the most efficient cars ever built. This automobile-of-the-future was called the Ford Nucleon, named for its highly unique design feature… a pint-size atomic fission reactor in the trunk. It was designed to use uranium fission to heat a steam generator, rapidly converting stored water into high-pressure steam which could then be used to drive a set of turbines. One steam turbine would provide the torque to propel the car while another would drive an electrical generator. Steam would then be
Advancement in DNA Computing 2006-10-17 12:25:00 Strands of DNA used to perform calculations has mastered the game tic-tac-toe. MAYA-II, developed at Columbia University and the University of New Mexico in the US, uses a system of DNA logic gates to calculate its moves for tic-tac-toe. A DNA logic gate consists of a strand of DNA which binds to another specific input sequence. This binding causes a region of the strand to work as an enzyme, modifying yet another short DNA sequence into an output string.Scientists have already developed DNA computers capable of various similar simple calculations. But the researchers behind MAYA-II say their design should prove particularly useful for exploring ways to identify the genetic markers associated with certain diseases. Read more:Computing
