specific impulse

There are two ways people find the number for specific impulse.

It had a specific impulse of nearly three hundred seconds, in fact.

When specific impulse is measured as a speed, it has another name.

The most common way to measure specific impulse today uses seconds.

The amount of fuel used to find specific impulse can be measured in different ways.

An engine with a higher specific impulse uses fuel better.

This means specific impulse can be used to compare engine performance in any country.

The higher the specific impulse, the more dazzling the engine.

This allows it to achieve a specific impulse of 301s at the Earth's surface.

For each stage the specific impulse may be different.

In addition it is important that thrust and specific impulse not be confused with one another.

Specific impulse is also used to measure performance in model rocket motors.

A high specific impulse means that a rocket needs less fuel to perform as well.

Some nuclear engines are envisioned as having a specific impulse of 900 seconds.

Black powder had a very low specific impulse, however.

By comparison, the planned engines would have a specific impulse of more than 900 seconds.

The design can, in theory, produce very high specific impulses while still being well within the abilities of current technologies.

If weight is used, the specific impulse is in units of time.

This provided 10% higher thrust, and higher specific impulse as well.

Theoretically, this should result in a better specific impulse than for rocket engines.

Specific impulse is a measure of the force based on how much fuel there is.

An engine that gives a large specific impulse is normally highly desirable.

It is also often used for upper-stage motors, due to its high specific impulse.

Sugar based rocket fuels have an average I(specific impulse) of between 115 and 130 seconds.

So, a fuel is more efficient if the specific impulse is higher.
