The launch pad built by the Soviet Union beginning in 1978 at the Baikonur Cosmodrome for launching the Energiya rocket included an elaborate sound suppression system which delivered a peak flow of 18 cubic metres (4,800 US gal) per second fed by three ground level reservoirs totaling 18,000 cubic metres (4,800,000 US gal).
The Reaction Research Society conducts complex amateur rocket projects, utilizing solid, liquid, and hybrid propellant technologies. The Tripoli Rocketry Association sanctions some amateur activities, which they call "research rocketry," provided certain safety guidelines are followed, and provided the motors are of relatively standard design.

A liquid-propellant rocket or liquid rocket uses a rocket engine burning liquid propellants. (Alternate approaches use gaseous or solid propellants.) Liquids are desirable propellants because they have reasonably high density and their combustion products have high specific impulse (I sp). This allows the volume of the propellant tanks to be ...
The Super-Heavy Lift Launcher (SHLL) would consist of a new cryogenic main stage, five liquid fly-back boosters, and a re-ignitable injection stage. This configuration was designed to provide increased capabilities for complex missions, including crewed explorations to the Moon and to Mars, as well as the launch of large solar-powered satellites.
The rocket is launched using liquid hydrogen and liquid oxygen cryogenic propellants. Rocket propellant is used as reaction mass ejected from a rocket engine to produce thrust . The energy required can either come from the propellants themselves, as with a chemical rocket , or from an external source, as with ion engines .
The gas-generator cycle, also called open cycle, is one of the most commonly used power cycles in bipropellant liquid rocket engines. Propellant is burned in a gas generator (or "preburner") and the resulting hot gas is used to power the propellant pumps before being exhausted overboard and lost.
Hybrid-propellant rockets use a combination of solid and liquid propellant, typically involving a liquid oxidizer being pumped through a hollow cylinder of solid fuel. All current spacecraft use conventional chemical rockets (solid-fuel or liquid bipropellant) for launch, though some [note 3] have used air-breathing engines on their first stage ...
