Propellants in a sentence

Electric Solid Propellants Electric Solid Propellants (ESPs) are a family of high performance plastisol solid propellants that have the unique property of being ignited and throttled by the application of electric current.

Double-base (DB) propellants DB propellants are composed of two monopropellant fuel components where one typically acts as a high-energy (yet unstable) monopropellant and the other acts as a lower-energy stabilizing (and gelling) monopropellant.

During World War II double based propellants were very widely used and there was some use of triple based propellants by artillery.

ETC increases the performance of conventional solid propellants, reduces the effect of temperature on propellant expansion and allows for more advanced, higher density propellants to be used.

Triple based propellants were used in post-war ammunition designs and remain in production for UK weapons; most double based propellants left service as World War II stocks were expended after the war.

Without the bright flame and dense smoke trail produced by the burning of aluminized propellants, these smokeless propellants all but eliminate the risk of giving away the positions from which the missiles are fired.

The launch must take place from Kennedy Space Center’s Launch Complex 39A, which is the only SpaceX pad at Cape Canaveral equipped to fuel the lander with liquid oxygen and methane propellants shortly before launch.

In recent years, North Korea has been pushing to develop more weapons with built-in solid propellants, which make launches harder to detect than liquid-propellant missiles that must be fuelled before liftoffs and cannot last long.

The stage was de-orbited from 650 km to 350 km, which facilitated its early re-entry, and was passivated to remove residual propellants to minimize any accidental break-up risks.

The Vulcan Centaur’s first stage is equipped with two BE-4 engines, each producing 550,000 pounds of thrust, using a combination of liquified natural gas and liquid oxygen as propellants.

Ozone-depleting substances, or ODS, were developed in the 1920s and ’30s and became popularly used as refrigerants, solvents and propellants.

The delivery of Blue Origin’s BE-4 was delayed over an issue with the engine’s complex single-shaft turbopump, the part of a rocket engine that injects flammable propellants during ignition with forces of 80,000 horsepower.

Elon Musk's rocket firm has also conducted ground systems testing and loaded it with propellants.

Lab results revealed the potion is largely made up of potassium nitrate and alunite which are not poisonous but are nevertheless used in pesticides, fertilisers and rocket propellants.

Musk later tweeted that the chamber pressure in the Raptor engine was too high because the methane and liquid oxygen propellants flowing into it were colder than expected.

Water ice is frequently mentioned as a key resource — not only because it can be melted down to slake a settler’s thirst, but also because it can be broken down into hydrogen and oxygen for rocket propellants.

The Long March 3B rocket burns a toxic mixture of hydrazine and nitrogen tetroxide propellants, a hypergolic combination that ignites when the two liquids make contact.

All of these rockets used liquid propellants.

Although propellants containing the highly toxic sodium azide (NaN 3 ) were common in early inflator designs, little to no toxic sodium azide has been found on used airbags.

A range of smokeless powders that contain both nitrocellulose and nitroglycerin, known as double-base propellants, were also developed.
