Computational Nozzle Design for Pulsed Detonation Thrusters for Vacuum Operations

This study presents the numerical design and optimization of a convergent–divergent nozzle integrated with a pulsed detonation combustor (PDC) operating under reduced outlet pressure conditions. The work builds upon an experimentally validated TRL 4 PDC with demonstrated vacuum operation, which provides realistic inlet...

Design and Development of a New Compression-Ignition Engine Concept for Aviation and UAV Applications

The design of piston engines for aviation applications requires the simultaneous consideration of power density, compactness, structural reliability, fuel efficiency, operational robustness, and system complexity. This study presents the design and development of a fully mechanical modular compression-ignition engine c...
