Liquid rockets ( or liquid-propellant rocket engine ) use one or more liquid propellants that are held in tanks prior to burning.

Liquid oxygen is a common liquid oxidizer propellant for spacecraft rocket applications, usually in combination with liquid hydrogen or kerosene.

* Boost Propulsion: Liquid fuelled rocket, LOX and Kerosene.

Liquid systems enable higher specific impulse than solids and hybrid rocket engines and can provide very high tankage efficiency.

The first number in the sequence indicates the number of stages ; the second the number of LRBs ( Liquid rocket boosters ); the third the number of SRBs ; and, if present, the fourth number shows the number of SSBs.

* Liquid rocket booster

A Liquid Rocket Booster ( LRB ) is similar to a solid rocket booster ( SRB ) attached to the side of a rocket to give it extra lift at takeoff.

A Liquid Rocket Booster has fuel and oxidiser in liquid form, as opposed to a solid rocket or hybrid rocket.

It uses the storable Liquid rocket propellants N2O4 / UDMH.

Liquid hydrogen is also used both as a fuel and as a coolant to cool nozzles and combustion chambers of rocket engines.

* Liquid fuel rocket

Liquid propellants generally have densities similar to water ( with the notable exceptions of liquid hydrogen and liquid methane ), and these types are able to use lightweight, low pressure tanks and typically run high-performance turbopumps to force the propellant into the combustion chamber.

Liquid propellants are also sometimes used in hybrid rockets, in which they are combined with a solid or gaseous propellant.

* Liquid propellants are subject to slosh, which has frequently led to loss of control of the vehicle.

* Liquid propellants often need ullage motors in zero-gravity or during staging to avoid sucking gas into engines at start up.

* Liquid propellants can leak, especially hydrogen, possibly leading to the formation of an explosive mixture.

* Liquid to solid cycle ( Frost heaving — water changing from ice to liquid and back again can lift rock up to 60 cm.

Liquid hydrogen has extremely low density ( 14 times lower than water ) and requires extensive insulation — whilst gaseous hydrogen requires heavy tankage.

* Liquid based cytology — The Pap smear sample is put in a bottle of preservative for transport to the laboratory, where it is then smeared on the slide.

Liquid oxygen — abbreviated LOx, LOX or Lox in the aerospace, submarine and gas industries — is one of the physical forms of elemental oxygen.

Liquid helium is used as a coolant for most superconductive windings, even those with critical temperatures far above its boiling point of 4. 2 K. This is because the lower the temperature, the better superconductive windings work — the higher the currents and magnetic fields they can stand without returning to their nonsuperconductive state.

# Liquid storage — Liquid oxygen is stored in chilled tanks until required, and then allowed to boil ( at a temperature of 90. 188 K (− 182. 96 ° C )) to release oxygen as a gas.

The Green Beret ( 1991 ) ( which was featured in an episode of " Liquid Television "; MTV misspelled his name " Hillenberg " in the credits ) and Wormholes ( 1992 ) became popular shorts in several film festivals — and received various awards.

Liquid silicone was used for lip augmentation, starting in the early 1960s but was abandoned thirty years later due to general — and later, unfounded — fears about the effects of silicone on general health.

Liquid air cycle engine —

Liquid fuels —

In all rockets, the exhaust is formed entirely from propellants carried within the rocket before use.

Examples include single -, double -, triple-based, and composite propellants, solid propellant rocket motors and ammunition with inert projectiles.

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.

In all rockets, the exhaust is formed entirely from propellants carried within the rocket before use.

Because of the enormous chemical energy in rocket propellants ( greater energy by weight than explosives, but lower than gasoline ), consequences of accidents can be severe.

He calculated the orbital speed required for a minimal orbit around the Earth at 8 km / s, and that a multi-stage rocket fueled by liquid propellants could be used to achieve this.

A solid rocket or a solid-fuel rocket is a rocket with a motor that uses solid propellants ( fuel / oxidizer ).

Higher performing solid rocket propellants are used in large strategic missiles ( as opposed to commercial launch vehicles ).

The solid rocket booster made the Minuteman faster to launch than earlier ICBMs, which used liquid rocket propellants.

A tripropellant rocket is a rocket that uses three propellants, as opposed to the more common bipropellant rocket or monopropellant rocket designs, which use two or one fuels, respectively.

One is a rocket engine which mixes three separate streams of propellants.

* Sodium nitrate (" Peru saltpeter " or " Chile saltpeter "), a component of fertilizers, explosives and solid rocket propellants ; also a food preservative

A rocket propellant combination used in a rocket engine is called hypergolic when the propellants spontaneously ignite when they come into contact with each other.

In Germany from the mid 1930s through World War II, rocket propellants were broadly classed as monergols, hypergols, non-hypergols and lithergols.

Thiokol Corporation moved operations to Redstone Arsenal from Maryland in the summer of 1949 to research and develop rocket propellants, while Rohm and Haas began work on rockets and jet propulsion.

The High Energy Density Matter ( HEDM ) project pushed the world of basic research in the area of physics and chemistry to find rocket propellants to surpass the capabilities of propellants existent at that time.

The project answered questions about the diffusion of liquid propellants in the event that a rocket was destroyed at high altitude.
