hypergolic fuel

This is a hypergolic fuel/oxidizer combination, and as such, it does not need an ignition system.

The Transtage, like the two core stages, used liquid hypergolic fuels.

Hypergolic fuel ignited in the reaction control nozzles, gently pushing them around the starship.

In the 1940s, the Russians began to start engines with hypergolic fuel, then switch over to the primary propellants after ignition.

Tanks of hypergolic fuel were purged and refilled.

These were hypergolic fuels which burn on contact, avoiding the need for an ignition system, and can be stored at ambient temperatures.

Soviet rocket engine researcher Valentin Glushko experimented with hypergolic fuel as early as 1931.

Toplivo Ghipergolicheskoye - hypergolic fuel (self igniting)

Wasserfall was to be launched from rocket bases (code-named Vesuvius) that could tolerate leaked hypergolic fuels in the event of a launch problem.

Another fuel, called hypergolic fuel, has two ingredients - monomethyl hydrazine and nitrogen tetroxide - that react violently when combined, even without an external spark.

The Titan II's hypergolic fuel and oxidizer ignited on contact, but they were highly toxic and corrosive liquids.

The tower will then be jettisoned 14 seconds later and the hypergolic fuel on the Orion CM would be automatically released at a pre-determined altitude.

The orbiters also carried hypergolic fuels for use in their RCS systems and in the Orbital Manoeuvring System.

Energia also replaced the "Vulkan" concept, which was a design based on the Proton rocket and using the same hypergolic fuels, but much larger and more powerful.

The most common hypergolic fuels, hydrazine, monomethylhydrazine and unsymmetrical dimethylhydrazine, and oxidizer, nitrogen tetroxide, are all liquid at ordinary temperatures and pressures.

The missile launch area also contained a separate fueling area surrounded by a large berm, a required safety precaution given the hypergolic fuels, and a variety of service areas.

The HWK 109-509 used a two-component hypergolic fuel/oxidizer combination, controlled by a dual-flow turbopump, to regulate the rate of combustion and thereby the amount of thrust.

Some launch vehicles such as the Titan II and Ariane 1 through 4 also use hypergolic fuels, although the trend is away from such engines for cost and safety reasons.

The Atlas booster had been modified since the previous flight, and now included baffled fuel injectors and a new hypergolic fuel igniter instead of the original pyrotechnic igniter.

At first, Yangel's facility served to mass-produce and further develop intercontinental ballistic missiles (ICBMs) in which area Yangel was a pioneer of storeable hypergolic fuels.

It is believed that hypergolic fuel may have leaked past valves in the system during the cruise to Mars, allowing the fuel and oxidizer to combine prematurely before reaching the combustion chamber.

This had the stronger rocket engine design team including the use of hypergolic fuels but following the Nedelin catastrophe in 1960 Yangel was directed to concentrate on ICBM development.

Other research by faculty and students include membrane separation of gases, scrubber systems for hypergolic fuels and oxidizers, and designing chemical plants for use on the Moon and Mars.

It is a three-stage launch vehicle with the first stage being solid-propelled, the second liquid-propelled (with hypergolic fuels) and the final stage being liquid propelled as well (with cryogenic fuels).

It took two minutes to fuel before launch, which can be a long time in high-speed intercepts, and its hypergolic fuels (hydrazine and nitric acid) were very dangerous to handle, leading to several serious accidents.
