	Jet aircraft - Wikipedia, the free encyclopedia
		The first aircraft to incorporate significant principles of the jet engine was the Coanda-1910 (Romania), piloted by its inventor Henri Coanda in 1910.
		Modern jets generally cruise at speeds of 0.75 to 0.85 Mach, which is to say, 75 percent to 85 percent of the speed of sound.
		The fastest jet plane remains the SR-71 Blackbird.

	Aircraft - Wikipedia, the free encyclopedia
		Fixed-wing aircraft generally use an internal-combustion engine in the form of a piston engine (with a propeller) or a turbine engine (jet or turboprop), to provide thrust that moves the craft forward through the air.
		Water cooled V engines, as used in automobiles, were common in high speed aircraft, until they were replaced by jet and turbine power.
		The major distinction in aircraft usage is between military aviation, which includes all uses of airplane for military purposes (such as combat, patrolling, search and rescue, reconnaissance, transport, and training), and civil aviation, which includes all uses of airplanes for non-military purposes.

	Definition of Aircraft engine
		The term aircraft engine, for the purposes of this article, refers to aircraft reciprocating, or rotary, internal combustion engines as opposed to jet engines or turboprops.
		Aircraft engines tend to be somewhere between 50% and 100% larger than a similarly powered modern car engine for a given power output.
		Several attempts to produce diesel aircraft engines were made in the 1930s but, at the time, the alloys were not up to the task of handling the much higher compression ratios used in these designs.

		In an aircraft gas turbine the output of the turbine is used to turn the compressor (which may also have an associated fan or propeller).
		The smallest jets are used for devices such as the cruise missile, the largest for future generations of commercial aircraft.
		The jet engine of Fig.2 is a turbofan engine, with a large diameter compressor-mounted fan.

	Aircraft Engine Emissions
		Aircraft engines produce emissions that are similar to other emissions resulting from fossil fuel combustion.
		that aircraft are estimated to contribute about 3.5 per cent of the total radiative forcing (a measure of change in climate) by all human activities and that this percentage, which excludes the effects of possible changes in cirrus clouds, was projected to grow.
		The Report recognized that the effects of some types of aircraft emissions are well understood, revealed that the effects of others are not, and identified a number of key areas of scientific uncertainty that limit the ability to project aviation impacts on climate and ozone.

	The Installed Jet Engine (Site not responding. Last check: 2007-09-15)
		Unlike a free standing jet engine, once installed in an Aircraft which is caused to move because of its action when used, the engine is required to perform two entirely different physical functions simultaneously.
		The second function is that in terms of fundamental dynamics the engine is required to be regarded and treated as an integral part of the Aircraft's structure.
		Consider, in terms of fundamental physics, and as far as the Aircraft is concerned, a unit of thrust force delivered to it is in fact of exactly the same physical value no matter if it is produced and delivered by a pure,bypass, variable cycle, fan, ram jet or rocket type of engine.

	The Jet Engine
		As things are, and according to convention, the maximum Gross Thrust which a jet engine is capable of delivering is achieved at maximum throttle when the vehicle containing the engine is in fact stationary and operating at Sea Level.
		And so, the physical efficiency of the engine as a Jet Engine, is determined by the efficiency in converting a unit weight of chemical fuel energy into Air Mass Motion Energy.
		Consequently, an installed Jet Engine in flight has no Propulsive Efficiency in its own right simply because it does not move relative to the Aircraft to which it is bolted.

		This paper addresses the stochastic modeling for advanced jet engine applications and also presents an overview of the basic theoretical aspects of different useful stochastic field models an then illustrates their application to practical problems.
		It is shown that stochastic fields adequately capture key random aspects of engine environment and behavior.
		The illustrated applications address stochastic modeling issues that are typical for engine structural analysis, such as time-varying operating speed conditions, manufacturing geometry deviations, and engine vibration, that produce highly nonlinear responses.

	Micro Aircraft Jet Engine
		Jim Gordon of Micro Aircraft demonstrated his jet-powered Mitchell Wing B-10 for the ultralight industry in April 1996.
		Still, it sure would be fun cruising around the neighborhood sounding more like a jet than a lawn-mower, even a John Deere.
		Back in February 1992, Jim Gordon from Micro Aircraft told Robert Goyer (who writes for SPORT PILOT magazine) that he bought a bunch of government-surplus turbines back in 1984 ranging from 60 hp to 8000 hp and is finding applications for them.

	F-16 Fighting Falcon - Military Aircraft
		Use of a single engine helped minimize weight and drag; use of a turbofan rather than a pure jet engine gave high fuel efficiency.
		USAF did not find this persuasive, in part because a two engine plane with one engine out is useless in combat, and the probability of an engine failure was nominally twice as high with two engines as with one.
		The first aircraft upgraded under CCIP were delivered to combat units in December 2001 (1).

	Aeronautics - Henri Coanda
		This procedure has so many applications that it is difficult to pick the most important ones: changing thrust direction for modern aircraft (thrust reversal), the lowering of noise levels for reactive engines (or for experimental stands) for high speed aircraft, and the lift of aerodynamic surfaces can be increased to name a few.
		The engine was the real innovation, though, and it is lost to the aircraft industry that development was not further pursued in 1910.
		Coanda's 'air-reactive engine' was housed under a cowl and was comprised of a four-cylinder, water-cooled, gasoline-powered engine rotating at 1000 rpm.

	Pulse Jet Engine
		One thing that immediately became apparent however, is that if the engines do lose synchronization, there's a definite tendency for the exhaust of one to be ingested by the other, resulting in a premature flame-out.
		Early tests on Jet A1 indicate that this thrust can be lifted to around 180lbs each and, with the addition of an augmentor, a figure of around 220lbs of static thrust per engine should be possible -- for a total of 440lbs.
		Please check out their engines, their quiet but efficient operation is almost the complete opposite of a jet engine, which makes them every bit as interesting.
