CYPRES II panel. In skydiving, an automatic activation device (AAD) is a dead man's switch consisting of an electronic-pyrotechnic or mechanical device that automatically activates the opening sequence of the main or reserve parachute container when the AAD is falling below a preset altitude and above a preset descent speed.
United States Air Force Pararescuemen jump at half the height of a typical HALO/HAHO insertion 2eme REP Legionnaires HALO jump from a C-160.. High-altitude military parachuting, or military free fall (MFF), is a method of delivering military personnel, military equipment, and other military supplies from a transport aircraft at a high altitude via free-fall parachute insertion.
If the parachute is deployed while the jumper is unstable, there is a high risk of entanglement or malfunction. The jumper may also not be facing the right direction. Such an off-heading opening is not as problematic in skydiving, but an off-heading opening that results in object strike has caused many serious injuries and deaths in BASE jumping.
He held the world record for the highest skydive—102,800 feet (31.3 km)—from 1960 until 2012. [1] [2] He participated in the Project Manhigh and Project Excelsior high-altitude balloon flight projects from 1956 to 1960 and was the first man to fully witness the curvature of the Earth.
A pressure suit is a protective suit worn by high-altitude pilots who may fly at altitudes where the air pressure is too low for an unprotected person to survive, even when breathing pure oxygen at positive pressure. Such suits may be either full-pressure (e.g., a space suit) or partial-pressure (as used by aircrew). Partial-pressure suits work ...
Speed skydiving is a competition discipline within the sport of skydiving. The competition objective is for the competitors to fly their body as fast as possible to achieve the highest average vertical speed through a 3-second window. The speed is measured using a speed measuring device (SMD) worn on the competitor's helmet.
Project Excelsior was a series of parachute jumps made by Joseph Kittinger of the United States Air Force in 1959 and 1960 from helium balloons in the stratosphere.The purpose was to test the Beaupre multi-stage parachute system intended to be used by pilots ejecting from high altitude.
Red Bull Stratos was a high-altitude skydiving project involving Austrian skydiver Felix Baumgartner.On 14 October 2012, Baumgartner flew approximately 39 kilometres (24 mi) [1] [2] [3] into the stratosphere over New Mexico, United States, in a helium balloon before free falling in a pressure suit and then parachuting to Earth.
