In 1944 he formed his own design bureau to engineer liquid-propellant engines.

He worked on many of the early tests of liquid-propellant rockets by the society.

This cooling design became the basis of all modern liquid-propellant rocket motors.

The Iraqis simply strapped liquid-propellant rockets to the sides.

Liquid-propellant rocket development has always proceeded in three steps:

Stage 1 used an LR87 liquid-propellant rocket engine.

On a single launch, an RM-81 Agena liquid-propellant upper stage was used.

Stage 2 used the LR91 liquid-propellant engine.

Gurrutu had been improvised from the liquid-propellant core booster of an Ariane 12 rocket.

He had laid down the ground work of the Liquid-propellant rocketry system and formulated the various mathematical theories of the rocket science.

A liquid-propellant rocket engine powered the second stage (modified Vanguard second stage, thrust about 7500 pounds).

The five rockets of the Southern Cross family will be based on Russia's Angara vehicle and liquid-propellant engines.

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

A liquid-propellant rocket or a liquid rocket is a rocket engine that uses propellants in liquid form.

After World War II the American government and military finally seriously considered liquid-propellant rockets as weapons and began to fund work on them.

The UR-100 was a two-stage liquid-propellant lightweight ICBM.

But based on the Kurds' information, I think the Iraqis might be working on a next generation Scud, one that uses liquid-propellant technology reliably."

In 1927, Crocco begun working with solid-propellant rockets and, in 1929, designed and built the first liquid-propellant rocket motors in Italy.

Draco are hypergolic liquid-propellant rocket engines that utilize a mixture of monomethyl hydrazine fuel and nitrogen tetroxide oxidizer.

Commonly referred to as the V-2 rocket, the liquid-propellant rocket was the world's first long-range combat-ballistic missile and first known human artifact to enter outer space.

Hence, all cryogenic rocket engines are also, by definition, either liquid-propellant rocket engines or hybrid rocket engines.

The rocket propulsion system was a four-chamber engine built by Reaction Motors, Inc., one of the first companies to build liquid-propellant rocket engines in America.

Design Tool for Liquid Rocket Engine Thermodynamic Analysis is a computer program to predict the performance of the liquid-propellant rocket engines.

The LR-87 was an American liquid-propellant rocket engine, which was used to propel the first stages of Titan intercontinental ballistic missiles and launch vehicles.

In the first ten years of SpaceX, the company has developed a variety of liquid-propellant rocket engines, with at least one more of that type under development in late 2012.
