		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.
		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.
		Today's rockets are remarkable collections of human ingenuity that have their roots in the science and technology of the past.

	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.
		Monopropellant systems are less complicated than bipropellant systems, so despite its lower specific impulse hydrazine is the chosen fuel for long missions where long-term reliability is important.

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

	Rocket Fuel Without Air
		Rocket fuel can be made such that other oxidizing agents are present (sometimes liquid oxygen).
		You then feed LOX with your fuel in the rocket engine and you have combustion.
		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.

	liquid-propellant rocket engine
		A rocket propulsion system that uses a liquid propellant, combining a liquid fuel (such as kerosene or liquid hydrogen) in a thrust chamber with a liquid oxidizer (such as liquid oxygen or fuming nitric acid).
		Unlike solid-propellant rocket motors, they can be shut off by remote command, simply by closing off their fuel line.
		In some cases, the thrust can also be varied over a certain range.

	Wired News: India Fires Supercool-Fuel Rocket
		The fuel cannot be stored in a rocket indefinitely because it is highly explosive, so a missile would have to be fueled before launching.
		Such engines, known as "cryogenic" engines, are fueled by liquid hydrogen and liquid oxygen.
		Rockets using these materials are primarily used to launch 2.5-ton communications satellites to orbits 22,000 miles above the earth.

	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.
		For rocket fuels, it is ideal to have 90% H2O2.
		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.

	NASM Space Artifacts: March 16, 1926 Goddard Rocket
		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.
		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.
		Finally, on January 20, 1926, he successfully tested a liquid propellant motor in a static test in which the motor produced more thrust than the rocket's weight.

	South Korea postpones launching landmark liquid-fuel rocket
		The country's first liquid-powered rocket has a thrust of 12.5 tonnes and was expected to have reached up to 42 kilometers (25.2 miles) with a maximum speed of 902 meters (2,976.6 feet) per second before falling into the Yellow Sea.
		The 14-meter-long (46.2-feet) rocket weighing six tonnes was to have blasted off from a launch pad in Anheung in the central province of South Chungcheong.
		The KSR-III rocket means the country has secured the technology needed to develop a satellite-launching vehicle in 2005, the Ministry of Science and Technology said.

	Howstuffworks "How Rocket Engines Work"
		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.
		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.
		The "strength" of a rocket engine is called its thrust.

	Bereznyak-Isayev BI rocket jet interceptor - history
		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.
		Polikarpov I-15 was powered by a 715-hp M-25 (a license-produced version of Wright-Cyclone) engine and 6 RS-82 solid-fuel rocket boosters.
		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.

	Vortex-Fired Liquid-Fuel Rocket Combustion Chambers
		If the fuel is fed through the wall, the upwelling oxygen burns the incoming fuel and carries it forward and into the axial vortex.
		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.

	The SS67B-3 Liquid Fuel Rocket Engine Kit!
		However, to demonstrate the safety of the propellants, the flask to the left is filled with oxidizer (50% Hydrogen Peroxide) and the fuel (gasoline).
		The kit includes a separate casing for increased flight stability, lower engine weight, increased performance, fewer parts (oxidizer tank and fuel tank have been incorporated into one assembly) and is easier to fuel and assemble.
		As with the B-1, The SS67B-3 works on the principle of using a pressurized gas stored in a high pressure reservoir to force liquid propellants into the combustion chamber (the pressurized gas is released with a high flow servo actuated valve).

	Robert_Goddard
		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 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.
		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.

	Booster Rocket
		A Booster in space-related applications is usually a solid fuel rocket-shaped device that is attached to the actual rocket to provide additional boost in the initial phase of the rocket's flight.
		There are also liquid fuel boosters (see also Ariane 4), these are called liquid boosters.
		Russia has delayed the launch of a European space probe that is meant to explore Venus on account of a problem with the Russian booster rocket.

	Fabricación
		The fabrication and assembly of a small liquid fuel rocket engine is no more difficult than the more serious amateur machine projects, such as model steam engines, gasoline engines, and turbines.
		Because the rocket engine has no rotating parts, dynamic balance of components is not required.
		Injection holes for the gaseous oxygen (and for the fuel, if impinging jets are used) will usually be made with numbered drills of small diameter.
