Notes: This was a completely insane concept in which there would be two stationary thrust chambers of lbf each surrounded by two rotating thrust chambers of lbf each. The rotating thrust chambers would drive the turbopumps through rotational motion. This would be the main engine for the Northrop XP and the prototype MX Hall Effect Thrusters. When the US was beginning to investigate the gridded ion drive, the Soviet Union was investigating the Hall Effect thruster (HET). This is a very similar concept in many ways to the ion drive, in that it uses the electrostatic effect to accelerate propellant, but the mechanism is very different.

A hybrid-propellant rocket is a rocket with a rocket motor that uses rocket propellants in two different phases: one solid and the other either gas or hybrid rocket concept can be traced back at least 75 years.

Hybrid rockets avoid some of the disadvantages of solid rockets like the dangers of propellant handling, while also avoiding some disadvantages of liquid rockets like their. The reaction mass (m r) is times the vehicle mass (m v), while the antimatter fuel mass is gly enough, this constant mass ratio is independent of the efficiency (η e) with which the antimatter energy is converted into kinetic energy of the exhaust.(If the antimatter engine has low efficiency, we will need more antimatter to heat the reaction mass to the best exhaust velocity.
