摘要

Pulse detonation engines (PDEs) are a revolutionary development in aircraft propulsion technology due to their new pressure-gain combustion thermodynamic cycle. This detailed review emphasizes significant performance parameters and optimization methods for PDE systems while firmly integrating recent computational and experimental work. There exists robust empirical verification that certain thrust performance can be enhanced up to 30% by precise adjustments in detonation frequency, combustion chamber configuration, and stoichiometric fuel-oxidizer ratios. When contrasted with traditional hydrocarbon fuels, hydrogen-propane binary blends exhibit 1% to 10% specific impulse improvements, and they demonstrate promise for increased efficiency. Advances are not only beneficial but also integral to the future of aeronautical technology. Nonetheless, significant research challenges hinder the full potential of PDE capabilities from being accomplished. These are the need for effective thermal management systems to mitigate excessive heat gradients, the challenge of maintaining stable deflagration-to-detonation transitions throughout operating cycles, and optimizing reactant mixture homogeneity across a spectrum of flight regimes. Furthermore, research into the potential advantages of integrating PDE propulsion into conventional turbomachinery and exploring alternative green propellants is still lacking. Future research needs to concentrate on the creation of new ignition techniques, including plasma-assisted and laser-induced detonations, and on the design of adaptive controls for dynamic frequency modulation in order to overcome these challenges. New cooling methods utilizing nanofluid heat transfer advancements are also very important. For satisfying stringent environmental criteria in contemporary aerospace propulsion technology, the present review offers a complete theoretical and experimental foundation for maximizing the thermal efficiency of PDEs. This has broad implications for the creation of orbital transport systems, enhancing defense systems, and developing hypersonic aircraft. Embracing these advancements is not merely beneficial but essential for the future of aerospace technology.
