Who invented the liquid fuel powered rocket?
Liquid rocket propellant propellant has been used for nearly 30 years. Many factors go into choosing a propellant for a liquid propellant rocket engine. The primary factors include ease of operation, cost, hazards/environment and performance. They can consist of a single chemical, a monopropellant, or two, called bipropellants or other mixtures. Bipropellants can be either hypergolic propellant or nonhypergolic. A hypergolic combination of oxidizer and fuel will start to burn upon contact. A nonhypergolic needs an ignition source. On March 16, 1926, Robert H. Goddard used liquid oxygen ("LOX") and gasoline as rocket fuels for his first partially successful liquid-propellant rocket launch. Both
Liquid rocket booster Liquid rocket booster A liquid rocket booster (LRB) consists of liquid fuel and oxidiser as booster to give a liquid-propellant rocket or a hybrid rocket an extra boost at take off. It is attached to the side of a rocket. In contrast to solid rocket booster it can be throttled. A liquid rocket booster (LRB) uses liquid fuel and oxidiser to give a liquid-propellant or hybrid rocket an extra boost at take-off, and/or increase the total payload that can be carried. It is attached to the side of a rocket. Unlike solid rocket boosters, LRBs can be throttled down, and
