	Tsiolkovsky rocket equation - Wikipedia, the free encyclopedia
		Tsiolkovsky's rocket equation, named after Konstantin Tsiolkovsky who independently derived it, considers the principle of a rocket: a device that can apply an acceleration to itself (a thrust) by expelling part of its mass with high speed in the opposite direction, due to the conservation of momentum.
		This equation was independently derived by Konstantin Tsiolkovsky towards the end of the 19th century and is widely known under this name.
		Thus the specific energy gain of the rocket in any small time interval is the energy gain of the rocket including the remaining fuel, divided by its mass, where the energy gain is equal to the energy produced by the fuel minus the energy gain of the reaction mass.

	Top Literature - Rocket
		A rocket is a vehicle, missile or aircraft which obtains thrust by the reaction to the ejection of fast moving exhaust gas from within a rocket engine.
		Rockets must be used when there is no other substance (land, water, or air) or force (gravity, magnetism, light) that a vehicle may employ for propulsion, such as in space.
		Rockets became extremely military important in the form of intercontinental ballistic missiles (ICBMs) when it was realised that nuclear weapons carried on a rocket vehicle were essentially not defensible against once launched, and they became the delivery platform of choice for these weapons.

	Konstantin Tsiolkovsky - One Language (Site not responding. Last check: 2007-10-14)
		Konstantin Eduardovich Tsiolkovsky (Konstanty Ciołkowski), (Константин Эдуардович Циолковский; September 5, 1857 new style – September 19, 1935) was a Russian of Polish ancestry, rocket scientist and pioneer of cosmonautics.
		His work influenced later rocketeers throughout Europe, and was also studied by the Americans in the 1950s and 1960s as they sought to understand the Soviet Union's early successes in space flight.
		Tsiolkovsky also delved into theories of heavier-than-air flying machines, independently working through many of the same calculations that the Wright brothers were doing at the same time.

	Tsiolkovsky
		Tsiolkovsky later remembered that his hearing loss influenced greatly his future life: during all his life he tried to prove to himself and to others that he was better and more clever than others, even with his disability.
		Tsiolkovsky was certain that the future of human life will be in outer space, so he deceded that we must study the cosmos to pave the way for future generations.
		Tsiolkovsky was very much as interested in the philosophy of space as he was with the engineering needed to make space flight possible.

		This equation (and variations) has stood the test of time and experience and should be applicable to all rocket type situations wherein the astronauts take their fuel along with them and use it to "push off of".
		Since the rocket "burn" is even and continuous, we can average the whole mass of exhaust as 75% of light velocity (for every bit going at 80% there is a corresponding bit going at 70%).
		Fuel is fed to the rockets through tubes running the length of the tether originating from a tanker stationary at the point of rotation of the entire apparatus.

		The thrust force of a rocket motor is the reaction experienced by the motor structure due to ejection of the high velocity matter.
		The rocket and fuel have a total mass M and the combination is moving with velocity v as seen from a particular frame of reference.
		The equation expresses that, when a particle is acted upon by a force F during a given time interval, the final momentum p2 of the particle may be obtained by adding its initial momentum p1 and the impulse of the force F during the interval of time.

	Tsiolkovsky's equation (Site not responding. Last check: 2007-10-14)
		where m 0 is the initial total mass, and m 1 the final total mass and v e the velocity of the rocket exhaust with respect to the rocket (the specific impulse, or, if measured in time, that multiplied by gravity-on-Earth acceleration).
		Clearly, to achieve a large delta-v, either m 0 must be huge (growing exponentially as delta-v rises), or m 1 must be tiny, or v must be very high, or some combination of all of these.
		In practice, this has been achieved by using very large rockets (increasing m 0), with multiple stages (decreasing m 1), and rockets with very high exhaust velocities.

	Spacecraft propulsion - ExampleProblems
		All current spacecraft use chemical rocket engines (bipropellant or solid-fuel) for launch, though some (such as the Pegasus rocket and SpaceShipOne) have used air-breathing engines on their first stage.
		The speed ratio of a rocket nozzle is mostly determined by its area expansion ratio—the ratio of the area of the throat to the area at the exit.
		Rockets emitting plasma can potentially carry out reactions inside a magnetic bottle and release the plasma via a magnetic nozzle, so that no solid matter need come in contact with the plasma.

	The Daily Princetonian - Next stop Mars: Professor to develop rocket prototype
		Tsiolkovsky's rocket equation shows that the more quickly fuel is released from a rocket, the less fuel needed to propel the rocket a given distance.
		In current chemical rockets, a slow three to four kilometer-per-second exhaust velocity means that up to 70 percent of the rocket must be filled with fuel, Choueiri said.
		These rockets use up an enormous amount of fuel, all of which must be carried up to the satellite at huge expense.

		The rocket equation shows why high exhaust velocity has historically been a driving force for rocket design: payload fractions depend strongly upon the exhaust velocity, as shown at right.

	Specific impulse - Engineering
		For a chemical rocket the propellant mass therefore would include both fuel and oxidizer; for air-breathing engines only the mass of the fuel is counted, not the mass of air passing through the engine.
		The advantage that this formulation has is that it may be used for rockets, where all the reaction mass is carried onboard, as well as aeroplanes, where most of the reaction mass is taken from the atmosphere.
		A rocket must carry all its fuel with it, so the mass of the unburned fuel must be accelerated along with the rocket itself.

	Re: Is a 'dry' compressed -air rocket feasible?
		Rockets fly because mass gets expelled at high velocity from one end - the larger the mass and the higher the velocity - the better.

		Water-air rockets work so well because they use relatively heavy liquid as their reaction mass.

		Modern rockets were born when, after receiving a grant in 1917 from the Smithsonian Institution, Robert Goddard attached a de Laval nozzle to a rocket engine's combustion chamber, doubling the thrust and enormously raising the efficiency, giving the real possibility of practical space travel.
		There the same rockets which would have been destined to rain down on Britain had the war continued were used by scientists for other uses.
