High Altitude

An image of the earth and the blackness of outer space, obtained by Luke and Max Geissbuhl...

It’s an inspiring story that reminds you how the wonders of scientific exploration aren’t just limited to research institutions with big budgets... in August of this year, Luke Geissbuhler and his seven year-old son Max attached an HD video camera to a weather balloon and set it loose. They proceeded to obtain footage of the blackness of outer space, 19 miles (30 km) above the surface of the earth. Needless to say, there was a little more to it than just tying a piece of string around a camcorder.  Read More

The Boeing SolarEagle will make its first demonstration flight in 2014 as part of DARPA's ...

The U.S. Defense Advanced Research Projects Agency’s (DARPA) Vulture program, which aims to develop and demonstrate technology to enable a single high-altitude unmanned airplane (UAV) to operate continuously for a period of five years, has entered phase II. Under the terms of an US$89 million contract, Boeing will develop a full-scale demonstrator called the SolarEagle that will make its first demonstration flight in 2014. The aircraft will have highly efficient electric motors and propellers and a high-aspect-ratio, 400-foot wing for increased solar power and aerodynamic performance.  Read More

Global Observer takes to the air for the first time

After AeroVironment’s recent announcement that its Global Observer unmanned aircraft system (UAS) had successfully completed a series of Wing Load tests the team apparently wasted no time getting the craft in the air for its maiden flight. On August 5 Global Observer 1001 took off from Edwards Air Force Base (EAFB) in California and climbed to an altitude of 4,000 feet where it performed a series of maneuvers before landing successfully one hour later.  Read More

Unveiled earlier this week in St. Louis, Boeing's Phantom Eye will set a new benchmark in long-endurance unmanned aerial vehicle (UAV) technology when it takes to the skies in 2011. With a wing-span of 150-feet, the hydrogen-powered aircraft will cruise at 150 knots, carry up to 450-pounds and stay aloft at 65,000 feet for up to four days. Boeing calls it a game-changer, and plans are already in progress to build a bigger version that can remain airborne for 10 days.  Read More

Felix Baumgartner practicing for his big, big jump

Later this year, Felix Baumgartner will put on a pressurized space suit and helmet, climb into a capsule suspended beneath a balloon, ride 120,000 feet into the earth’s upper atmosphere, then jump out and – before deploying his parachute – try to break the speed of sound while in freefall. That’s the plan, at least, for the insanely-dangerous Red Bull Stratos event. If successful, it will constitute the world’s highest manned balloon flight, highest parachute jump, and fastest and longest freefall. The team conducted three important tests in the last week of May, that they just released the details of this week. What those tests entailed would probably be hair-raising enough to last most of us a lifetime.  Read More

Magenn's MARS floating wind generator

Wind power is notoriously flighty, particularly at ground level. Most turbine-on-a-post wind powered generators operate at around 20-40% of their rated generation capacity, simply because wind is intermittent and changes direction. But a generator situated 500-1000 feet above ground level would enjoy much more consistent strong wind - which is why the Magenn MARS system makes so much sense. It's a helium-filled rotating airship that spins in the wind on the end of a variable-length tether that also acts as a power transmitter, and it's expected to operate at more like 50% of its rated capacity. Each MARS system will be cheap and portable, which will make them extremely useful in rural, camping and emergency situations. A prototype has successfully been flown in North Carolina. A great idea that makes economic sense.  Read More

October 30, 2007 The Boeing Company has achieved a milestone in the development of its High Altitude Long Endurance (HALE) unmanned aircraft by successfully testing a hydrogen propulsion system in simulated conditions of 65,000 feet. The test, conducted over more than three days using a Ford Motor Company-developed hydrogen engine (a gasoline version of which can be found in the Ford Fusion and Escape Hybrid) is a further step towards the realization of a UAV designed to remain airborne for more than seven days and carry multi-sensor payloads of up to 2,000 pounds.  Read More

High altitude launch capability demonstrated for MK-54 torpedos

May 30, 2007 If there’s an absolute truth about military technology, it’s that it keeps getting more deadly with each passing year and the High Altitude ASW Weapons Concept (HAAWC) is a prime example. HAAWC employs the Lockheed Martin LongShot Wing Adapter Kit to allow the launch of torpedoes from high altitudes and long standoff ranges, allowing aircrews to remain beyond the reach of enemy air defences. Additionally, the manoeuvrability of the concept allows for off-axis launch of torpedoes at potential undersea targets preventing the need for the aircraft to manoeuvre.  Read More

F-22 scores direct hit in supersonic, high-altitude JDAM drop

The U.S. Air Force F-22 Combined Test Force team of Boeing, Lockheed Martin and Air Force pilots continued to successfully push the F-22 Raptor's capability last week when it released a Joint Direct Attack Munition (JDAM) munition at supersonic speed, high altitude and standoff range. Flying at an altitude of 50,000 feet and a speed of Mach 1.5, the F-22 released a GPS-aided, 1,000-pound JDAM from a range of 24 nautical miles, destroying a ground target in the aircraft's fastest and highest JDAM delivery to date. The ability to release a munition at supersonic speeds and standoff ranges greatly enhances the aircrew's survivability against heavily defended targets.  Read More
