Specific impulse measures how effectively a rocket engine creates thrust from the mass it throws out the back, whether by chemical or any other means. The higher the specific impulse of a rocket ...

We are fascinated by the hybrid rocket engine which [Ben Krasnow] built and tested in his shop. It is actually using a hollow cylinder of acrylic as the fuel, with gaseous oxygen as an oxidizer.

Compared to more "conventional" rocket engines, BE-4 and Raptor are cheaper ... Efficiency is everything in rocketry, which ...

In order to significantly increase the effectiveness, performance and specific impulse of future rocket engines, high combustion chamber pressures are required above all. If the combustion chamber ...

The engine demonstrates enhanced thrust performance (at least 6 Newtons) and specific impulse (at least 100 ... at the Troitsk site to test the plasma rocket engine prototype and other similar ...
