DOI: 10.1016/j.actaastro.2019.03.076

Abstract: Abstract The high specific impulse of the ramjet engine, coupled with the potential of a gel to carry boron particles, makes the boron-based gel fuel ramjet a most appropriate solution for a mid-high range sustainer.… read more here.

DOI: 10.1016/j.combustflame.2016.10.012

Abstract: Abstract The decomposition characteristics of five candidate polysulfide (LP-33) based ramjet solid fuel formulations are evaluated using thermogravimetric analysis and differential scanning calorimetry. The formulations are variants on the polymer crosslink mechanism and the doping… read more here.

DOI: 10.1063/5.0281994

Abstract: The rocket-aided ramjet engine integrates high-thrust rocket engines into the flow passage of the ramjet, effectively broadening the operating speed range and altitude capability of the ramjet. This integration enables rapid thrust modulation and stable… read more here.

DOI: 10.1119/1.5009919

Abstract: 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… read more here.
