Credit: NASA, public domain Before we dive into the world of ion thrusters, it’s important to understand the concept of specific impulse and fuel efficiency for rocket thrusters of all kinds.

In order to significantly increase the effectiveness, performance and specific impulse of future rocket engines, high combustion chamber ... development of space transportation systems. The thrust ...

The paper mentions that specific impulse values twice the suggested upper range could be possible with the proper selection of thruster and propellant. They also point out that development on ...

It has both a high thrust and high specific impulse. Specific impulse is how quickly a rocket engine generates thrust, and thrust is the force that moves the spacecraft along. The PPR generates ...

Like liquid rocket engines, hybrid rocket motors can be shut down easily and the thrust is throttleable. The theoretical specific impulse (Isp) performance of hybrids is generally higher than solid ...

How effective are cold air thrusters, though? The rocket equivalent of fuel efficiency is called “specific impulse”. The higher a rocket engine’s specific impulse, the more efficient it is.

This high thrust allows the rocket to accelerate faster. These systems also have a high specific impulse. Specific impulse measures how efficiently the propellant is used to generate thrust. Nuclear ...
