Transoceanic Abort Landing
Space Shuttle abort modes were procedures by which the nominal launch of the NASA Space Shuttle could be terminated. A pad abort occurred after ignition of the shuttle's main engines but prior to liftoff. An abort during ascent that would result in the orbiter returning to a runway or to an orbit lower than planned was called an "intact abort", while an abort in which the orbiter would be unable to reach a runway, or any abort involving the failure of more than one main engine, was called a "contingency abort". Crew bailout was still possible in some situations in which the orbiter could not land on a runway. Redundant set launch sequencer abort The three Space Shuttle main engines (SSMEs) were ignited roughly 6.6 seconds before liftoff, and computers monitored their performance as they increased thrust. If an anomaly was detected, the engines would be shut down automatically and the countdown terminated before ignition of the solid rocket boosters (SRBs) at T = 0 seconds. This ...

Space Shuttle Single Engine Out Abort Timeline
Space is the boundless three-dimensional extent in which objects and events have relative position and direction. In classical physics, physical space is often conceived in three linear dimensions, although modern physicists usually consider it, with time, to be part of a boundless four-dimensional continuum known as spacetime. The concept of space is considered to be of fundamental importance to an understanding of the physical universe. However, disagreement continues between philosophers over whether it is itself an entity, a relationship between entities, or part of a conceptual framework. Debates concerning the nature, essence and the mode of existence of space date back to antiquity; namely, to treatises like the ''Timaeus'' of Plato, or Socrates in his reflections on what the Greeks called ''khôra'' (i.e. "space"), or in the ''Physics'' of Aristotle (Book IV, Delta) in the definition of ''topos'' (i.e. place), or in the later "geometrical conception of place" as "space ...

Space Shuttle External Tank
The Space Shuttle external tank (ET) was the component of the Space Shuttle launch vehicle that contained the liquid hydrogen fuel and liquid oxygen oxidizer. During lift-off and ascent it supplied the fuel and oxidizer under pressure to the three RS-25 main engines in the orbiter. The ET was jettisoned just over 10 seconds after main engine cut-off (MECO) and it re-entered the Earth's atmosphere. Unlike the Solid Rocket Boosters, external tanks were not re-used. They broke up before impact in the Indian Ocean (or Pacific Ocean in the case of direct-insertion launch trajectories), away from shipping lanes and were not recovered. Overview The ET was the largest element of the Space Shuttle, and when loaded, it was also the heaviest. It consisted of three major components: * the forward liquid oxygen (LOX) tank * an unpressurized intertank that contains most of the electrical components * the aft liquid hydrogen (LH2) tank; this was the largest part, but it was relatively ...

Learjet C-21
The Learjet Model 35 and Model 36 are a series of American multi-role business jets and military transport aircraft manufactured by Learjet. When used by the United States Air Force they carry the designation C-21A. The aircraft are powered by two Garrett TFE731-2 turbofan engines. Its cabin can be arranged for six to eight passengers. The longer-range Model 36 has a shortened passenger area to provide more space in the aft fuselage for fuel tanks. The engines are mounted in nacelles on the sides of the aft fuselage. The wings are equipped with single-slotted flaps. The wingtip fuel tanks distinguish the design from other aircraft having similar functions. Development The concept which became the LJ35 began as the Learjet 25BGF (with GF referring to "Garrett Fan"), a Learjet 25 with a then-new TFE731 turbofan engine mounted on the left side in place of the 25's General Electric CJ610 turbojet engine. This testbed aircraft first flew in May, 1971. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flight Surgeon
A flight surgeon is a military medical officer practicing in the clinical field of aviation medicine. Although the term "flight surgery" is considered improper by purists, it may occasionally be encountered. Flight surgeons are physicians ( MDs or DOs) who serve as the primary care physicians for a variety of military aviation personnel on special duty status — e.g., pilots, Flight Officers, navigators/ Combat Systems Officers, astronauts, missile combat crews, air traffic controllers, UAV operators and other aircrew members, both officer and enlisted. In the United States Department of Defense, the Army, Navy, and Air Force all train and utilize flight surgeons. In addition to serving as primary care for military members on special duty status and their families, the U.S. Department of Defense uses flight surgeons for a variety of other tasks. Aviation medicine is essentially a form of occupational medicine and flight surgeons are tasked with the responsibility of mainta ...

Pararescue
Pararescuemen (also known as PJs) are United States Air Force Special Operations Command (AFSOC) and Air Combat Command (ACC) operators tasked with recovery and medical treatment of personnel in humanitarian and combat environments. These special operations units are also used to support NASA missions and have been used to recover astronauts after water landings. They are attached to other special operations units from all branches to conduct other operations as appropriate. Of the roughly 200 Air Force Cross recipients, only 24 are enlisted rank, of which 12 are Pararescuemen. Part of the Air Force Special Operations community and long an enlisted preserve, the Pararescue service expanded to include Combat Rescue Officers early in the 21st century. History Pre–World War II As early as 1922, there was a recognized need for trained personnel to go to remote sites to rescue airmen. In that year, Army Medical Corps doctor Colonel Albert E. Truby predicted that "airpl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Patrick Space Force Base
Patrick Space Force Base is a United States Space Force installation located between Satellite Beach and Cocoa Beach, in Brevard County, Florida, United States.

RAF Fairford
Royal Air Force Fairford or more simply RAF Fairford is a Royal Air Force (RAF) station in Gloucestershire, England which is currently a standby airfield and therefore not in everyday use. Its most prominent use in recent years has been as an airfield for United States Air Force B-52s during the 2003 Iraq War, Operation Allied Force in 1999, and the first Gulf War in 1991. It is the US Air Force's only European airfield for heavy bombers. RAF Fairford was the only TransOceanic Abort Landing site for NASA's Space Shuttle in the UK. As well as having a sufficiently long runway for a shuttle landing (the runway is long), it also had NASA-trained fire and medical crews stationed on the airfield. The runway is rated with an unrestricted load-bearing capacity, meaning that it can support any aircraft with any type of load. RAF Fairford is also the home of the Royal International Air Tattoo (RIAT), an annual air display. RIAT is one of the largest airshows in the world, with the 2 ...
