Cryogenic fuels are fuels that require storage at extremely low temperatures in order to maintain them in a liquid state. These fuels are used in machinery that operates in space (e.g. rockets and satellites) where ordinary fuel cannot be used, due to the very low temperatures often encountered in space, and the absence of an environment that supports combustion (on Earth, oxygen is abundant ...
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).
Ammonium perchlorate composite propellant (APCP) is a solid rocket propellant.It differs from many traditional solid rocket propellants such as black powder or zinc-sulfur, not only in chemical composition and overall performance but also by being cast into shape, as opposed to powder pressing as with black powder.
Chinese startup OrienSpace said it has scheduled the debut launch of its solid-fuel rocket, Gravity-1, in December. Deep Blue Aerospace, which is developing a reusable kerosene-fuelled rocket ...
In the case of solid rocket motors, the fuel and oxidizer are combined when the motor is cast. Propellant combustion occurs inside the motor casing, which must contain the pressures developed. Solid rockets typically have higher thrust, less specific impulse , shorter burn times, and a higher mass than liquid rockets, and additionally cannot be ...
Perchlorate, a chemical found in rocket fuel, has contaminated water and food and is more likely to be found in food given to babies and children, a study from Consumer Reports found.
A key ingredient in rocket fuel can be found in a wide array of foods we eat, especially baby food, fast food and fresh fruits and vegetables, according to an explosive new investigation from ...
