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:

RAFALE multirole fighterjet at Paris Air Show 2011

The French Dassault RAFALE multirole fighter aircraft should be omnipresent at Le Bourget PAS 2011 as it has been shortlisted as a final competitor versus the Typhoon Eurofighter for the Indian MMRCA tender which will make a decision on the purchase of up to 126 multirole jetfighters. Furthermore, the French aircraft is still a contender in the Brazilian bid request, and it has been shortlisted in the Swiss NAC tender.

Nonetheless – and maybe « thanks » to some media always « forgetting » to state the outstanding results of the RAFALE in theaters of operations as well as in exercises and evaluations – this state-of-the-art fighter has never been exported so far… Watch the video – First comments in French, then in English:

The Chinese J-20 « Black Eagle » 5th generation fighter could be superior to the F-35 Lightning II, and even on a par with the F-22 Raptor with its range, radar-evading stealth capability, as well as with its firepower. – Video:

France flagStrange as it may seem, the French have not managed to export Rafale fighter aircraft so far…

However, the Rafale has been deemed to be an excellent fighter aircraft so many times – formidable in dogfighting, awesome when it strikes, and its superb CATIA-designed streamlining turns it into a feline grace nonetheless redoubtable whenever it is to be challenged in the skies.

There have already been rumours such as:

Rafales – thanks to its RCS (Radar Cross Section) –  would have beaten F/A-18s Hornet.

– After several dogfights reported between the Rafale and the Raptor, ( Rafale vs F-22 Raptor:  1 – 1 , according to the rumours ) BVR engagement exercises would have been cancelled. Another version deems that F-22s never took part in such exercises, so what did they do there at that time? Sightseeing? Not to mention the F-22’s withdrawal at the Paris Air Show 2009…

– The Rafale was onboard American CVs (aircraft carriers) in 2007, 2008, and 2009. The rumour in forums spread about American fighter aircraft that could not stand the Rafales’ level of performance during exercises.

But who knows, actually? However, some other elements have also been reported. They do not come from forums or blogs. So, can they be called « rumours »?

For instance, I still remember an article from The New York Times dated July 16th 2006. It was reported that the Rafales could outfly F-15, F-16 and F-18 opponents in dogfights. They also won against F-15s and Eurofighter Typhoons in technical and performance evaluations . The American media paid tribute to the French jet but almost nobody knew that in France at that time. How bizarre… Well, it must be admitted that there is a curious fad in France that consists in criticizing everything that works.

Remember, according to French TF1 channel in 2008… This was the balance sheet:

FAF Rafales vs USAF F-16s :  6 – 2

Moreover, the former Red Arrows team leader – Peter Collins – stated last month that it should be done justice to this aircraft for the Rafale would be according to him – as he had just flown a standard F3 Rafale – a « war-fighter par excellence ». He added that he deemed the Rafale to be the best and most complete combat aircraft that he had ever flown. He concluded in saying that if he had to go into combat, on any mission, against anyone, he would, without question, choose the Rafale.

Last but not least, the French Rafales would have slammed – if I may put it this way – the other aircraft in an exercise in the UAE – United Arab Emirates. Even the F-22 Raptor – though 5th generation fighter – could hardly do anything to « tame » this tough challenger. According to Jean-Marc Tanguy’s information, defence journalist, the balance sheet lies in the figures hereafter:

Dogfighting (with Rafale weapons system’s performance lowered on purpose):

FAF Rafales vs RAF Typhoons :  4 – 0

Dogfighting with further Rafale weapons system reduction:

FAF Rafales vs RAF Typhoons :  3 – 1

Final balance sheet (in both scenarii the Rafales did not have full weapons systems…):

FAF Rafales vs RAF Typhoons :  7 – 1

Not to mention Rafales outperform F-16CJs in targeting while in air-to-air and ground attacks thanks to the Rafale’s FSO – Front Sector Optronic.

I read from a remarkable Swiss aviation specialist’s website: AVIA NEWS. Pascal – AVIA NEWS webmaster – let me quote his analysis according to which the Rafale obtained the best score (95%) among the fighter aircraft evaluated for choosing which will replace the Swiss Air Force’s F-5 Tiger. The other two competitors were the SAAB JAS-39 Gripen, and the Eurofighter / Typhoon.

Furthermore, the Dutch did compare various fighter aircraft in 2002. Who remembers? The RNLAF – the Royal Netherlands Air Force – carried out this study and the balance sheet came out in the Dutch press:

Here are the ratings reported:

F-35 = 6.97

RAFALE = 6.95

Eurofighter = 5.83

F-16 Block 60 = 5.80

Well, we must admit that the JSF / F-35 Lightning II is the best fighter among those that were assessed. However it was a close shave, wasn’t it?

You will find an excerpt below of Jean-Marc Tanguy’s post from his blog « Le Mamouth« :

La première confrontation engageant quatre Rafale contre quatre Typhoon s’est terminée par un 4-0 en faveur des Français. Malgré, explique-t-on, l’emport d’un armement air-air fictivement dégradé. Après avoir un peu dégradé encore l’armement, le Rafale l’a encore emporté, 3-1.
Le Rafale a été confronté au F22 lors d’un vol, mais dans un cadre limité au combat air-air à vue. Il n’aurait été dans le collimateur du chasseur américain qu’ à une reprise, explique t-on aussi. CLIQUEZ ICI pour lire L’ARTICLE ENTIER en français
