GREAT VIDEO – Watch for pleasure, first. Listen carefully to the figures and phrases uttered and compare with the various texts that are enforced in the world, and in Europe. In such an extreme situation, you may understand that the procedures are turned into a faster phraseology. So, why not adopt it in GAT (General Air Traffic), after all? 😉

SUPERBE VIDÉO: Regardez d’abord pour le plaisir. Écoutez attentivement les chiffres et expressions et comparez les avec les textes en vigueur dans le monde et en Europe. Dans une situation aussi extrême, on peut comprendre que les procédures se fassent plus rapidement dans la phraséologie. Alors pourquoi ne pas l’adopter dans la CAG (Circulation Aérienne Générale), après tout? 😉

SKYDIVER Felix BAUMGARTNER’s TOP 5 JUMPS

Felix Baumgartner, the famous Austrian skydiver, is still waiting for better meteorological conditions to make a new attempt in the Red Bull Stratos project to break the sound barrier while freefalling. This new feat might happen within the next few days as it has already been scheduled on October 14.

According to the video below, Felix BAUMGARTNER’s top 5 jumps are:

  1. Wingsuit Channel Crossing
  2. Taipei 101 BASE Jump
  3. Petronas Towers BASE Jump
  4. Seating of the Spirits Cave Jump
  5. Man vs. Plane

 


Felix BAUMGARTNER was to jump on the 9th of October 2012. However, this jump which could have become the highest skydive in the aerospace history has been put off due to gusty winds.

In this new record attempt Felix BAUMGARTNER will be so high up – 120,000 ft, or 36.6 km – that if his suit leaks, his blood will boil. When he jumps, he will fall so fast that he will break the sound barrier as explained in this video:

 

 

A 3-hour ascent is expected to reach such an altitude, and it could take him more than a quarter of an hour to fall down back to the earth, and land… And now the animation on how it could unfold from the stratosphere right over Roswell, New Mexico, USA: (Click on the link below – MUST SEE!)

GO FELIX!

SKYDIVER TO BREAK NEW FREE FALL RECORD

 

Felix Baumgartner, an Austrian skydiver, performed a challenging test jump on Thursday March 15, 2012.

Felix Baumgartner has the right stuff. He is a well known BASE jumper. B.A.S.E. means Buildings; Aerials; Spans (jumps from bridges); and Earth (jumps from cliffs). He performed numerous stunts such as jumping from the Petronas Towers in Kuala Lumpur, the statue of Christ the Redeemer in Rio de Janeiro, World Financial Center T101 in Taipei, and the Millau viaduct.

Yesterday’s jump test is just a stage in his attempt to break a new free-fall record. He jumped above Roswell, New Mexico at an altitude of 71,581 feet ie 21.8 kilometers; 13.6 miles; or Flight Level 716. He should then carry out another jump test before leaping again from a capsule lifted by a helium balloon at around 120,000 ft ie 23 miles or 37 km this year, and could become the first man to break the sound barrier while free falling.

 


 

MEDICAL CHALLENGE

This is not a simple leap in the sky. People may not understand how dangerous skydiving at such heights is. The air density is so low that it cannot brake movements as drag becomes poorer up there.

Therefore, a position mistake can make the human body tumble violently or spin very fast. High rotation speeds involve high-G forces due to the centrifugal force, and may lead to G-LOC (G-force induced Loss Of Consciousness), and even to the rupture of blood vessels.

Moreover, if a spacesuit were to leak (due to a dormant seal failure or a cracked/crazed faceplate, for instance), the blood could be boiling (ebullism at 37°C above 63,000 ft or 19 km) because of the very low air pressure, and the body could be swelling, and actually freezing to death as the external temperature can reach down to -70°C, and even lower, not to mention the risk of pulmonary barotrauma.

The current record is held by Joseph Kittinger (a former USAF pilot who is curently advising Felix Baumgartner on his project) who jumped from 102,800 feet in 1960. He temporarily lost the use of his hand which got twice as big as a glove seal was leaking during the final part of the ascent. With this test jump, Felix Baumgartner already belongs to the highest three skydivers along with Joe Kittinger, and Russian Eugene Andreev who performed the longest parachute jump from 83,523 feet (25.5 km).

The following video shows that this feat is not only a matter of pushing limits as researchers are working on this Red Bull Stratos project to prepare flight safety of the future spacecraft:

MACH-20 AEROSPACECRAFT

New-York to Los Angeles in 12 minutes… It would have been a record-breaker, had it worked:

The DARPA and USAF FALCON project might give anybody the thrill of speed as this « aerospacecraft » has been designed to reach Mach 20 i.e. around 20,000 km/h; 5.6 km/s; 10,800 knots; or 12,400 mph depending on the air temperature, and the altitude which might be above at least FL900!

Unfortunately, the project seems to encounter major difficulties as the last test which unfolded on August 11, 2011 failed again. The previous one – also on an HTV2 – had failed in April. Click on the right-hand side picture to get further information on the first test. The Blackswift (HTV-3X)  had been designed by ATK; Boeing; Lockheed Martin; and Skunk Works to provided a strategic strike anywhere in the world within an hour. It was cancelled due to a lack of funds (see the HTV-3 shown in the following video):

 


 

  • DARPA stands for Defense Advanced Research Projects Agency
  • FALCON stands for Force Application and Launch from CONtinental United States
  • FL stands for Flight Level (FL x 100ft = altitude)
  • HTV stands for Hypersonic Test Vehicle or Hypersonic Technology Vehicle
  • RCS means here in the videos: Reaction Control System (and not Radar Cross Section)

AD-150 HIGH-SPEED VTOL DRONE

Thanks to its HTAL (High Torque Aerial Lift) advanced tilt-duct propulsion system, the AD-150 Unmanned Aircraft System (UAS) has been designed to take off and land vertically (VTOL) as well as reach a speed of about 300 knots.

It is still being developed by American Dynamics Flight Systems. Its airframe is to be made up of carbon fiber and kevlar materials. It could be one of the most effective drones of its generation with its versatile payload configuration; GCS interfaces; and interoperable data links. Its Pratt and Whitney engines could be feed with Jet-A; JP-4; and JP-5 fuel.
