What happened to the balloon after Baumgartner’s leap? Is Baumgartner a pilot? Does a human body make a sonic boom? We investigate the answers to these questions and more.
4. Was there a TFR for the jump?Nope. The FAA was clearly routing traffic around the area, but there were no official TFRs for the jump.
Number ten is a very week answer, as it only partially answers a question about the gondola. Red Bull made it very clear that the envelope, the 'balloon' portion that holds the gas, had a mechanism to be ripped open when the gondola was released for its descent. Once enough gas escaped the envelope it would descend on its own - tracked and eventually recovered by a ground team.
All I get is number ten on the web page and the "next" button doesn't function.
#5: no, he hasn't jumped from the same balloon (red bull's site specifically says the balloons are one-time use only), but he has jumped from the same capsule...
Q 11. Cost approximately 3M US - revenue to red bull priceless.
I suspect if you are having trouble clicking to move to the next question as airsteve172 did, that you are using the IE9 browser.
The fix is to "right clck" on the NEXT button and select OPEN.
Or, you can read it in Chrome!
'It does but not a very big one. Baumgartner reported that he didn’t feel it or hear it.'
This is an inadequate answer, evidently flying magazine has a resident self-qualified armchair aerodynamicist. A sonic boom is a pressure wave created by the supersonic passage of an object through the air, it is inaudible to the object, or occupant travelling supersonic because they themselves are creating the pressure wave, the 'BOOM' is only audible if you experience the pressure wave impact. Concorde passengers never heard the plane go BOOM as it passed through Mach 1... people on the ground probably did but the 'sonic boom' is not a singular event the occurs when passing through the threshold of Mach 1, it is a continuous wave dragged along by the supersonic object all the while it is travelling above Mach 1. Any person passed by a supersonic object will hear the boom!
And finally, as for 'not a very big one', this assertion is made on the basis of what? That a little spaceman isn't big enough to make a very big bang? Have you ever heard a 7.62mm assault rifle being fired? The 'crack' you hear from large caliber rifles is the sonic boom being made by the bullet, and that's a projectile much smaller than a whole man in a space suit! The 'boom', if you had been hovering at altitude while Felix zoomed past you in free fall, would have been VERY loud, but because the pressure waves would have radiated out horizontally and dissipated into the atmosphere it would have been inaudible on the ground because Felix was travelling vertically! Sonic booms heard from supersonic aircraft flying overland are only heard because they are travelling horizontally and part of the shockwave is directed down toward the ground.
PeetPilot is 100% correct. I have heard both a 7.62 (Will never forget the sore shoulder sighting in a scope that turned out to be bent) and Concorde. I have seen a documentary on the first Concorde passengers that were disappointed going through Mach one with no sound and no bumps.
I would however be interested about the temperature changes or any heat generated by the free-fall.
I thought it was clear that Felix was joking about the boom, but I've fixed that. Should have been more literal here. As far as balloon/capsule is concerned, thanks for your feedback. No, he never jumped from a balloon but from a gondola/capsule, though "balloon" is often, as here, used as shorthand for the entire system. Thanks for all the feedback.
Before he jumped, could Felix see what he was aiming for as far as a landing site? Also how close was he to the launch site when he landed?
Maybe (and that's a key word here) the sonic boom was weak because:
1- The speed was barely above that of the sound. I think he barely made it to M 1.1. It's quite often in modern airliners that the airflow around it achieves, in some zones, slightly supersonic speeds, but since the freestream is actually subsonic the supersonic flow must necessarily slow down again to subsonic speeds, and the only way for supersonic flow to slow down is with a shock wave, so shockwaves are formed, but they are weak enough that when a triple 7 cruises 33.000 ft above your you don't feel any sonic boom.
2- The supersonic speed was achieved at a very high altitude, where even the enormous drag coefficient of such a blunt object at transonic and supersonic speeds plus the high speed itself made little drag due to the extremely low density. I guess that in such conditions, the energy carried by a shockwave must be weak. I mean, ok, there is a brisk increase in air pressure, but few air molecules are involved. Or anybody ever heard the shockwave of the Space Shuttle during re-entry?
It is not correct to say that Austrian base jumper Felix Baumgartner became the first person to ever go faster than the speed of sound without the benefit of a craft.
The earth is rotating at a speed that is higher than the sound . Any people on the equator is travelling at 1666km/h without even moving, that 30% faster than the speed of sound
Is that a joke?
It's obvious that motion is relative. Nothing is moving or not moving until you state about what, that is, the frame of reference.
The people on the North pole is moving about the Sun much faster than what you said about the people on the Equator. And what is "the speed of sound" anyway? The sound in the hardened steel travels way much faster than your people on the Equator. With these "constructions" we will be soon talking about going faster than light.
But when you talk "supersonic", you talk of the speed of something about the surrounding medium where sound waves propagate. Now, what were you saying about the people on the Equator?
I would be interested in knowing how Felix overcame the tumbling/ spinning during his descent.
At an aviation seminar in Puyallup, Washington several years back a military pilot speaker told of ejecting from his crippled jet that was going virtually straight down at something like 800 MPH. His flight suit was torn off him and he was badly injured. Unfortunately his back seater was torn apart and died. According to the pilot it was the highest speed from which anyone had ever ejected and survived.
Old Pilot says that the 800MPH speed was the fastest. A number of pilots/RSOs ejected from SR-71s. Some lived, some died.
I'm sure there were others that ejected from high-speed aircraft (I imagine a number punched out of F-104s and F-105s at supersonic speeds.)
Also, I believe there were rocket-sled tests done at supersonic speeds.
The whole list:
Be that as it may - the sudden wind blast would tend to bust you up pretty good.
As far as Felix goes - his speed was vertical against almost NO ATMOSPHERE at all!
Question No. 6, How much it cost. According to some newspapers about $ 50 million. Red Bull sponsor (power drink) argued that a number of scientific tests would be carried out expanding the knowledge about physiology of the human body and this and that. Well this is just a bunch of baloney as this was done only for advertisment. If you bring this arguments to Flight Surgeons at Nasa, Air Force and Navy they will laugh at you, there is nothing that the stunt revealed that they did not know for years. For $ 50 million they got millions of viewers watching the saga on TV around the world and also reams and reams of newspaper reporting this stunt. Had they had to pay for this coverage it would have been in the hundreds of millions.
This isn't about the jumpers skill, but his overcoming fear. They probably should have picked someone that wasn't suffering from claustrophobia. It makes no difference as anyone that is brave enough to fall out of a capsule at high altitude qualifies to reproduce this feat. Not impressed, besides, the Navy did this act many years ago, if you care to know.
There was a productive result related to improvement of pressurized suits, what in my understanding it was highly costumized for the type of jump requiring fine movements for leaving the capsule and adjust body positioning during free fall; which by the way require a great deal of training and practice. In those speeds any movement, minimal changes in body position or limbs, even hands can induce unrecoverable spins. It is also more difficult to control the body in free fall at less dense atmosphere. In essence Baumgartner deserves a great deal of prize for his feat that could easly kill anyone without proper skills. I would not be surprised either if some of the experiences and materials utilized in this project, specially the pressurized suit, will find its way into comercial space flight, an industry that is no in the hands of NASA anymore, but private enterprises.
