		Today's rockets are remarkable collections of human ingenuity that have their roots in the science and technology of the past.
		By the 16th century rockets fell into a time of disuse as weapons of war, though they were still used for fireworks displays, and a German fireworks maker, Johann Schmidlap, invented the "step rocket," a multi-staged vehicle for lifting fireworks to higher altitudes.
		Fueled by liquid oxygen and gasoline, the rocket flew for only two and a half seconds, climbed 12.5 meters, and landed 56 meters away in a cabbage patch.

		A liquid can usually be contained within a glass or a similar container without allowing escape.
		A liquid can freeze to become a solid or evaporate into a gas.

	The Planetary Society: Propulsion for Space Travel - Liquid Fuel Rockets
		Liquid fuel rockets are similar to solid fuel rockets, but the propellant is stored in a liquid form and pumped to a combustion chamber, where it is mixed with oxidizer and ignited.
		Unlike solid fuel rockets, the amount of thrust that a liquid fuel rocket produces can be controlled or even turned off by reducing the flow of fuel from the tank to the combustion chamber.
		Many liquid propellants have to be kept at very low temperatures to remain stable because they are gases at room temperature; and if an accidental leak of propellant gas occurs, the gas is usually highly toxic to humans.

		By 1926 he had designed, built, and flown the world's first liquid fuel rocket.
		Launched 75 years ago today from his aunt Effie's farm in Auburn Massachusetts, the rocket, dubbed "Nell", rose to an altitude of 41 feet in a flight that lasted about 2 1/2 seconds.
		Widely recognized as a gifted experimenter and engineering genius, his rockets were many years ahead of their time.

	The First Liquid Fuel Rocket
		In his studies he recognized that solid fuels produced a lower exhaust velocity than could be obtained by the use of liquid fuels.
		A liquid fuel requires a continuous source of oxidizer to be able to burn at a rate capable of producing the rocket thrust desired.
		After 21/2 seconds of flight, the fuel was expended, the roar ceased abruptly, and the rocket fell to earth 184 feet away.

	NASM Space Artifacts: March 16, 1926 Goddard Rocket
		This section of the rocket consists of the oxidizer tank (containing liquid oxygen, or lox, needed for combustion) and the smaller fuel tank, containing gasoline, for burning with the lox.
		The rocket was mainly made of aluminum with steel tubes serving as the propellant lines and steel combustion chamber and nozzle.
		The development of modern liquid fuel rocketry was therefore the result of the work of several experimenters, many working independently of each other, though Goddard was afterwards recognized as technically the first to develop such systems.

		Rocket jet propulsion for fighter aircraft was seriously studied in the USSR beginning in early 1930's.
		Rocket boosters in aviation were considered from two main directions: as supplemental power source used during take-off and whenever extra thrust was needed; and as the main source of thrust.
		The Tikhonravov "302" (AKA I-302) was powered by the RD-1400 liquid fuel rocket engine mounted in the rear fuselage, developing 1200 kgf of static thrust (or by the RD-2M rocket engine with 600 kgf of thrust), and by two wing-mounted PVRD ramjet boosters.

	Rocket Fuel Without Air
		Rocket fuel can be made such that other oxidizing agents are present (sometimes liquid oxygen).
		The fuel is the very thick rubber walls of the long, tubular combustion chamber, and the oxidizer is N2O gas injected down the tube from a pressure-tank in front.
		Solid rockets have an oxidizing agent mixed in the solid propellant, which after all is what the air does.

	Vortex-Fired Liquid-Fuel Rocket Combustion Chambers
		The other propellant (typically, liquid hydrogen) is injected either from the head end or through a porous liner in the chamber wall.
		The circumferential component of the injection flow forms a free vortex that spirals forward along the wall of the barrel to head end, where it turns inward to form a second vortex, concentrated along the axis, that flows out of the chamber at the aft end.
		If the fuel is fed through the wall, the upwelling oxygen burns the incoming fuel and carries it forward and into the axial vortex.

	Liquid Fuel Rockets - The Explosives and Weapons Forum
		Anyhow, if you don't know how a liquid fuel rocket works, here's how: It pumps the pressurized fuel into a combustion chamber, where it is burned (duh), and the pressurized gasses are released from the nozzle and thus propel the rocket.
		The Fuel Tank would be pressurized right before launching the rocket using a CO2 cannister perhaps, thus pushing the fuel into the Combustion chamber to be burnt.
		For rocket fuels, it is ideal to have 90% H2O2.

	Howstuffworks "How Rocket Engines Work"
		Thrust is measured in "pounds of thrust" in the U.S. and in Newtons under the metric system (4.45 Newtons of thrust equals 1 pound of thrust).
		One of the funny problems rockets have is that the objects that the engine wants to throw actually weigh something, and the rocket has to carry that weight around.
		That is why you have to have a huge rocket to get a tiny person into space right now -- you have to carry a lot of fuel.

	INTRODUCTION (Site not responding. Last check: 2007-11-04)
		The rocket engine is a relatively simple device in which propellants are burned and the resulting high pressure gases are expanded through a specially shaped nozzle to produce thrust.
		A liquid rocket engine employs liquid propellants which are fed under pressure from tanks in to a combustion chamber.
		The thrust force of a rocket motor is the reaction experienced by the motor structure due to the ejection of the high velocity matter.

		It was during this stage of his life (1895-1902), that Paulet reached the first conclusions that would lead him to the discovery of liquid rocket fuel, and later to the physical principles upon which he based the conception and design of the Paulet Engine, the Girándula device, and, finally, his Torpedo Plane.

		However, he realised that any vehicle used to go there could not use solid fuel as it could not generate sufficient power for a rocket to leave the atmosphere and defeat gravity.
		Goddard also faced the problem that the power generated by a rocket would have to be greater than the weight of the rocket itself - and it would need some power to spare.
		Goddard believed that if hydrogen could be piped into a combustion chamber sufficiently quickly and burnt with liquid oxygen, it would produce the desired force to propel a rocket to the Moon.
