Thermal Release Characteristics of Aeroengine Combustor Outlet Modulated by Gliding Arc Plasma

Advanced Science, Volume 12, Issue 41, November 6, 2025.
Gliding arc plasma‐assisted combustion significantly improves aeroengine combustor. Gliding arc plasma moves flames closer to the fuel source, enabling complete burning. This increases the combustion efficiency by 10.3% and raises outlet temperature by 141.6°C.

Tau Zero: In the cockpit of a Bussard ramjet [PDF]

American Journal of Physics, 2017
A Bussard ramjet is a relativistic spacecraft, fueled by fusion energy of cosmic matter that is collected during the flight. We derive the equation of motion of such a spaceship for a given mass density in space and the fusion mass defect. Two ramjet engine scenarios, where the thrust for propulsion is generated by emission of photons or acceleration ...
