The engine successfully lifted its own weight in a 27-second test in the static rack. It was a major success for Goddard, proving that a liquid fuel rocket was possible. [16]: 140 The test moved Goddard an important step closer to launching a rocket with liquid fuel. Goddard conducted an additional test in December, and two more in January 1926.
Many Chinese launch vehicles have been using liquid boosters. These include China's man-rated Long March 2F which uses four liquid rocket boosters each powered by a single YF-20B hypergolic rocket engine. [6] The retired Long March 2E variant also used similar four liquid boosters. [7] as did Long March 3B [8] and Long March 3C variants.
Dr. Robert H. Goddard launched his historic rocket on March 16, 1926, from what was then the Asa Ward Farm. The 10-foot (3.0 m) rocket reached an altitude of 41 feet (12 m), flew for two-and-a-half seconds, and fell to the ground 184 feet (56 m) from the launching frame.
Robert H. Goddard stands with the world's first liquid-propellant rocket on Pakachoag Hill in Auburn on March 16, 1926. When launched, the rocket soared 341 feet high and 184 feet downrange in 2.5 ...
The liquid-fuel rocket is a rocket with an engine that uses propellants in liquid form. On March 16, 1926, in Auburn, Massachusetts, Dr. Robert H. Goddard, the "father of modern rocketry", launched the first liquid-fueled rocket in history, which used liquid oxygen and gasoline as propellants. [1] 1927 Bread slicer
An LR105 Atlas sustainer engine on display at the Air Zoo.. The LR105 is a liquid-fuel rocket engine that served as the sustainer engine for the Atlas rocket family. [1] [2] [3] Developed by Rocketdyne in 1957 as the S-4, [4] [5] [6] it is called a sustainer engine because it continues firing after the LR89 booster engines have been jettisoned, providing thrust during the ascent phase.

The engine may be a cryogenic rocket engine, where the fuel and oxidizer, such as hydrogen and oxygen, are gases which have been liquefied at very low temperatures. Most designs of liquid rocket engines are throttleable for variable thrust operation. Some allow control of the propellant mixture ratio (ratio at which oxidizer and fuel are mixed).
