Jet engines take a large volume of hot gas from a combustion process ( typically a gas turbine, but rocket forms of jet propulsion often use solid or liquid propellants, and ramjet forms also lack the gas turbine ) and feed it through a nozzle that accelerates the jet to high speed.

Jet engines are generally used in cruise missiles, most commonly of the turbojet type, due to its relative simplicity and low frontal area.

Jet aircraft are propelled by jet engines, which are used because the aerodynamic limitations of propellers do not apply to jet propulsion.

Until the beginning of the Jet Age, piston engines were common on propliners like the Douglas DC-3.

Prior to the Jet Age, it was common for the same or very similar engines to be used in civilian airliners as in military aircraft.

For example large Jet engines operate around 10, 000 rpm, while micro turbines spin as fast as 500, 000 rpm.

Jet engines that produce thrust from the direct impulse of exhaust gases are often called turbojets, whereas those that generate thrust with the addition of a ducted fan are often called turbofans or ( rarely ) fan-jets.

Jet engines come in several main types:

Hudsons and Nashes each used their own engines as they had previously: the Hudson Hornet continued to offer the I6 that had powered the ( NASCAR ) champion during the early 1950s ; the Wasp now used the former engine of the Hudson Jet.

Jet engines, as a class, can supply increased fuel efficiency at supersonic speeds, even though their specific fuel consumption is greater at higher speeds.

Almost all production business jets, such as General Dynamics ' Gulfstream and the Gates Lear Jet ( now built by Bombardier ), have had two or three engines, though the Jetstar, an early business jet, had four.

Aircraft Gas Turbine engines ( Jet Engines ) are responsible for much of the aircraft noise during takeoff and climb.

Optional engines included the-2V ( standard on GTs ), the new for 1969-2V Windsor, 351-4V Windsor ,-4V, and the-4V Cobra Jet ( standard on Cobras ).

Available engines included the 302-2V, a 351-2V " Windsor " or " Cleveland ", a 351C-4V " Cobra Jet " ( CJ ), a 400-2V, and a 429-4V.

Like in previous years, all Torino options could be ordered, including all-new Ram-Air 429 Cobra Jet or Super Cobra Jet engines ( 7 L ) with a slightly different " shaker " hood scoop borrowed from the Mustang, so named because it was directly mounted to the carburetor and shook with the engine at idle.

Jet turbine engines use different operating principles and have their own sets of controls and sensors.

Although a few Caprices were sold with the new Turbo Jet V8 mated to a four-speed manual transmission, most were built with the more-civilized V8 engines such as the Turbo Jet V8 to handle multitudes of luxury options such as air conditioning, power windows, Cruise-Master speed control, power seats, an automatic headlight dimmer ( 1965 only ) and stereo radios.

Both the 250-and Turbo Fire engines were designed to use regular gasoline while the 350 Turbo Fire and both 454 Turbo Jet engines required premium fuel.

The fact that the Deerstalker and the Jet were the only completely new designs this year doesn't mean that 1961 didn't see changes in models, actions and calibers.

There were also many popular games officially converted to the Electron from arcade machines ( including Crystal Castles, Tempest, Commando, Paperboy and Yie Ar Kung-Fu ) or other home computer systems ( including Impossible Mission, Jet Set Willy, The Way of the Exploding Fist, Tetris, The Last Ninja, Barbarian and SimCity ).

The first jet aircraft to enter service in October 1980 were six Alpha Jet CI light attack and advanced training aircraft ; six more were ordered, but were subsequently cancelled.

In 1934, Caltech was elected to the Association of American Universities, and the antecedents of NASA's Jet Propulsion Laboratory, which Caltech continues to manage and operate, were established between 1936 and 1943 under Theodore von Kármán.

Watanabe, however, made no secret that, in addition to Lupin III, the series paid subtle tribute to his favorite American films and series, which were shown in Japan during the 1970s and ' 80s including Butch Cassidy and the Sundance Kid ( the relationship between Spike and Jet ), Bruce Lee films ( Spike's martial-arts practice ), films with blues or jazz soundtracks ( the music of the series ), as well as Blaxploitation films ( the series has a very racially diverse supporting cast ).

High-precision ephemerides of sun, moon and planets were developed and calculated at the Jet Propulsion Laboratory ( JPL ) over a long period, and the latest available were adopted for the ephemerides in the Astronomical Almanac starting in 1984.

Researchers at NASA's Jet Propulsion Laboratory and the University of Kansas reported in February 2006 that the glaciers are melting twice as fast as they were five years ago.

Due to health reasons these plans were cancelled, and they remained in the U. S., where Larry instead joined the NASA Jet Propulsion Laboratory after he finished graduate school.

In Europe, the console was most widely known as the Philips Videopac G7000, or just the Videopac, although branded variants were released in some areas of Europe under the names Philips Videopac C52, Radiola Jet 25, Schneider 7000, and Siera G7000.

Many unofficial Spectrum clones were produced, especially in the former Eastern Bloc countries ( e. g. in Romania, several models were produced ( Tim-S, HC85, HC91, Cobra, Junior, CIP, CIP 3, Jet ), some featuring CP / M and a 5. 25 "/ 3. 5 " floppy disk ) and South America ( e. g. Microdigital TK 90X and TK 95 ).

Soviet-built thrusters were introduced to the West in 1992 after a team of electric propulsion specialists from NASA's Jet Propulsion Laboratory, Glenn Research Center, and the Air Force Research Laboratory, under the support of the Ballistic Missile Defense Organization, visited Soviet laboratories and experimentally evaluated the SPT-100 ( i. e., a 100 mm diameter SPT thruster ).

Mariner 3 ( together with Mariner 4 known as Mariner-Mars 1964 ) was one of two identical deep-space probes designed and built by Jet Propulsion Laboratory ( JPL ) for NASA's Mariner Mars 1964 Project that were intended to conduct close-up ( flyby ) scientific observations of the planet Mars and transmit information on interplanetary space and the space surrounding Mars, televised images of the Martian surface and occultation data of spacecraft radio signals as affected by the Martian atmosphere back to Earth.

On 8 November 1985, Stephen Edberg ( then serving as the Coordinator for Amateur Observations at NASA's Jet Propulsion Laboratory ) and Charles Morris were the first to observe Halley's comet with the naked eye in its 1986 apparition.

These two space probes were built at the Jet Propulsion Laboratory in Southern California, and they were paid for by the National Aeronautics and Space Administration ( NASA ), which also paid for their launchings from Cape Canaveral, Florida, their tracking, and everything else concerning the space probes.

Some of Murdoch's other minor inventions and experiments were: a machine developed in 1784 or 1785 in Cornwall for drilling wooden pipes, ( in 1810 this was further developed and patented for stone pipes ), a steam cannon which he attempted to use in 1803 to knock down a wall at Soho, a steam gun in the same year which fired 3 cm lead bullets, and machinery to grind and compress peat moss under great pressure to produce a material with " the appearance of the finest Jet ".

Jet airliners were added in 1960, with the introduction of the Douglas DC-8 and four years laters Eastern beacme the launch customer of the Boeing 727 and the shuttle became all-jet in 1968 with a fleet of dedicated Boeing 727s and DC – 9s.

Many of the techniques of digital image processing, or digital picture processing as it often was called, were developed in the 1960s at the Jet Propulsion Laboratory, Massachusetts Institute of Technology, Bell Laboratories, University of Maryland, and a few other research facilities, with application to satellite imagery, wire-photo standards conversion, medical imaging, videophone, character recognition, and photograph enhancement.

These were joined by bands with hard rock leanings that emerged in the mid-2000s from the garage rock or post punk revival, including Black Rebel Motorcycle Club and Kings of Leon, and Queens of the Stone Age from the US, Three Days Grace from Canada, Jet from Australia and The Datsuns from New Zealand.

The Lunar mascons were discovered by Paul M Muller and William L Sjogren of the NASA Jet Propulsion Laboratory ( JPL ) in 1968 from a new analytic method applied to the highly precise navigation data from the unmanned pre-Apollo Lunar Orbiter spacecraft.

In 1980 and 1981 as a NASA Faculty Fellow and in 1983 as a NASA Consultant he worked at Jet Propulsion Laboratory on orbital mechanics and attitude control, where he applied geometric algebra in development of new mathematical techniques published in a textbook / monograph New Foundations for Classical Mechanics.

To date, the term Jet Rock is infrequently applied to anyone other than Guitar Wolf itself.

Shortly after introducing the Jet, Trans-Lux applied the same innovations to closed-circuit television.
