Increasing Cermet Fuel Thermal Margin with Thoria for Nuclear Thermal Propulsion
Nuclear thermal propulsion (NTP) technology was identified as an alternative for faster space travel over chemical combustion propulsion systems by NASA in its Design Reference Addendum 5.0. Potential improvements to NTP performance were considered by improving the fuel margin to melting point. A …

Design Options to Address Submersion Criticality for Low-Enriched Uranium Nuclear Thermal Propulsion Rocket
… method between Earth and Mars. Nuclear thermal propulsion (NTP) is well suited to be the main propulsion mechanism for interspace travel due to its high specific impulse. In order to develop a robust NTP system, the reactor core must be able to prevent a supercritical state from …

Combustion diagnostics in Homogeneous Charge Compression Ignition optical and thermal single cylinder engines
… a Homogeneous Charge Compression Ignition (HCCI) engine with a negative valve overlap (NVO) strategy. Conventional (pressure-transducer based) measurements and passive optical research have contributed to understanding of the chemical-physical sites of HCCI autoignition and combustion. This …
