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.
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).
The rocket, developed by LandSpace, uses the TQ-12 engine. Vulcan Centaur successfully reached orbit on its first try, called Cert-1, on 8 January 2024. [26] The rocket, developed by United Launch Alliance, uses the Blue Origin's BE-4 engine, though the second stage uses the hydrolox RL10.
The startup, which was founded in 2017, had been working towards test flights of its first spacecraft, making progress including an early successful engine test using its experimental, more eco ...
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 ...
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.
