See more at impulse Examples of specific impulsespecific impulse However, as already noted, specific power rather than specificimpulse is the primary constraint. Indeed, under the same conditions which led to a specificimpulse the first time, one finds that the second time yields significantly different results. All three staging methods require additional material reducing the overall specificimpulse. In this way, a large thrust at a high specificimpulse would be imparted onto the pusher plate, and hence the spacecraft. In aiming at the highest possible specificimpulse, we thus propose as a fourth staging principle, a method based on staged magnetic reflectors produced by superconducting magnetic field coils. A propellant with a higher specificimpulse is said to be more efficient because more thrust is produced while consuming a given amount of propellant.

This does not always apply, not even in all cases where efficiency can be assigned a numerical value, e.g. not for specificimpulse.

The propellant mix that would produce the greatest specificimpulse for a rocket motor is sometimes given as oxygen difluoride and pentaborane.

These values are used in equations similar to the rocket equation and are analogous to specificimpulse or exhaust velocity.

The consequent heating of the shield will cause it to radiate visible light, which could then be collimated to increase the rocket's specificimpulse.

If it is given in terms of weight (such as in kiloponds or newtons), then specificimpulse has units of time (seconds).

Nonetheless, the high specificimpulse of electrical thrusters may significantly reduce the cost of the flight.

The ammonium perchlorate makes up the oxygen deficit introduced by using nitrocellulose, improving the overall specificimpulse.
