https://en.wikipedia.org/wiki/Hypergolic_propellantA hypergolic propellant combination used in a rocket engine is one whose components spontaneously ignite when they come into contact with each other. The two propellant components usually consist of a fuel and an oxidizer. The main advantages of hypergolic propellants are that they

Hypergolically-fueled rocket engines are usually simple and reliable because they need no ignition system. Although larger hypergolic engines in some launch vehicles use turbopumps, most hypergolic engines are pressure-fed....
Xem thêmPyrophoric substances, which ignites spontaneously in the presence of air, are also sometimes used as rocket fuels themselves or to ignite other fuels. For example a mixture of triethylborane and triethylaluminium(which are both separately and even more

Hypergolique — Wikipédia
https://fr.wikipedia.org/wiki/HypergoliqueHypergolique. Un article de Wikipédia, l'encyclopédie libre. Les ergols hypergoliques sont des couples de composés chimiques qui, lorsqu'ils entrent en contact mutuel, s'autocatalysent leur oxydoréduction ( combustion ). Le mélange s’enflamme spontanément. Ils sont employés notamment en propulsion spatiale car ils n'ont pas besoin d'un ...
Hypergolität – Wikipedia
https://de.wikipedia.org/wiki/Hypergolität- Zündung
Die Komponenten hypergoler Treibstoffe sind meist starke Oxidations- und Reduktionsmittel, die sich bei Kontakt sofort, teilweise explosionsartig, entzünden. Da der Treibstoff nach dem Einspritzen in die Brennkammer sofort reagiert und brennt, kann sich nie zu viel Treibstoff in der … - Umweltschädlichkeit und Lagerung
Die Komponenten hypergoler Treibstoffe sind oft hochreaktiv und deshalb meist giftig, instabil und schwierig zu lagern. Bei größeren Waffensystemen ist man daher zu Feststoffboostern übergegangen. Da hypergole Treibstoffe eine Gefahr für Mensch und Umwelt darstellen, werden …

https://es.wikipedia.org/wiki/Propergoles_hipergólicos- El investigador soviético de motores cohete Valentin Glushko experimentó con combustibles hipergólicos en 1931. Inicialmente se utilizaba para la "ignición química" de los motores de queroseno / ácido nítrico mediante una carga inicial de fósforo disuelto en disulfuro de carbono. El profesor alemán Otto Lutz descubrió independientemente el principio de nuevo en 1935. El co…
