When the flow of this substance is too high, over-pressurization may lead to a hard start.
When the flow of this substance is too high, over-pressurization may lead to a hard start. Germany often used a mixture of triethylamine and xylidine as a type of this substance named "tonka" while Russia used an expensive chemical named "syntin". The amount of work that can be extracted from the consumption of this substance is given by the Tsiolkovsky equation. If two types of this substances are hypergolic, they spontaneously ignite when coming into contact. In most configurations, turbopumps mix this kind of substance with an oxidizer in a cylinder called a (*) combustion chamber. Examples of this kind of substance, which can be liquid or solid, include hydrazine and liquid oxygen. For 10 points, name this type of propellant used to provide thrust for spacecraft.
