Joseph William Kittinger II (born July 27, 1928) is a retired Colonel in the United States Air Force Pilot and command USAF. Operational duty was in fighter aircraft, he participated in Project Manhigh and Project Excelsior in 1960, set a world recordfor highest skydive from a height of over 31 kilometres (19 MI). He also made the first crossing of the Atlantic Ocean with a hot-air balloon.
As a fighter pilot during the Viet Nam War, he has destroyed the MiG-21 fighter jet of North Viet Nam and then shot down himself, spent 11 months as a prisoner of war in North Viet Nam prison. In 2012, at the age of 84, he participated in the Red Bull Stratos Project as capsule communicators, directing the Felix Baumgartner tomemecahan a record 31 kilometers of his freefall from the Earth's stratosphere, exceeding its own freefall on his behalf earlier in 1960
How much does the speed of sound (Mach)?
Mach is a unit of speed that is common to express the speed of an aircraft relative to the speed of sound. The unit is usually placed before the measurement figures such as Mach 1.0 for the speed of sound, Mach 2.0 for twice the speed of sound. The actual number depends on speed of sound pressure level and temperature of the atmosphere. At 0 ° C air temperature and air pressure 1 atmosphere (atm), the speed of sound is 1,088 ft/s or m/s or 331.6 748 mi/h (at a height of 2-3 kilometres)
How Joseph William Kittinger speed while doing the action?
Joseph Kittinger speed of freefall time reached 614 mph (988 km/h) where these exceed supersonic speed or the speed of sound. He opened the umbrella on the parachute at an altitude of 18,000 feet (5,500 m).
Let's count become units of metres/second 988km/h = 988000/3600 = 274.444 m/s
For info: Flip Joseph Kittinger was only armed with a parachute and without assisted by vehicle/accelerator tool
Does a flip is simply to break through the wall of the speed of sound?
No, the function of the flip is to design a new generation of space suits. Clothes to wear specially designed to protect the paratroopers of low air temperature and pressure and pressure shock wave as he broke through the wall of sound.
In addition, the flip is also done to develop methods of self rescue for astronautswho have experienced problems in extreme height and provide information on astronauts and space tourists concerning the expansion of the ' safe zone '.
For info: it's been a lot of victims from this flip research.
