Thermal analysis and performance of a pressure gain combustion system
2017Conventional gas turbine engines burn fuel in a steady state combustor at constant pressure, and the pressure rise is obtained by the compressor driven by the turbine. In the Pressure Gain Combustion cycle, the combustion process is at constant volume, allowing an increase of the pressure without the need of the compressor.

Potential Benefits to Commercial Propulsion Systems from Pressure Gain Combustion
49th AIAA/ASME/SAE/ASEE Joint Propulsion Conference, 2013A study was conducted to analyze the potential fuel burn benefits of pressure gain combustion technology applied to commercial aircraft. The propulsion systems of modern, large aircraft consist of either turboprop or turbofan engines with annular combustors; airflow through these combustors typically experiences a stagnation pressure drop around 4 ...

Experimental Study of Pressure Gain Combustion with Hypergolic Rocket Propellants
Journal of Propulsion and Power, 2017This paper summarizes experimental observations of pulsed combustion occurring in a 4.5 cm diameter, nozzleless rocket combustor for pressure gain combustion applications. The combustor featured an impinging jet injector and operated on high-concentration hydrogen peroxide with a catalyst-laced hydrocarbon-based fuel.

Characterization of Axial Turbines for Pressure Gain Combustion
2019Pressure gain combustion is beneficial for engine cycle efficiency, compactness, and less emissions. In this disseration, two classes of fluid expansions systems were developed to harness power from the high-speed flow delivered by the pressure gain combustor: a compact expansion system and an efficiency expansion system.

Steam injected Humphrey cycle for gas turbines with pressure gain combustion
Energy, 2019Abstract Gas turbines are a mature technology and any increase in their efficiency comes at high R&D cost. Pressure Gain Combustion (PGC) has emerged as a concept to significantly improve their efficiency. Technically, PGC is realized through detonative combustion or approximations of constant volume combustion.

Methods for Achieving a Combustion-Driven Pressure Gain in Gas Turbines
Journal of Engineering for Gas Turbines and Power, 1988The objective of the work was to compare on both an ideal and, where possible, an actual basis the approximate performances of four types of pressure-gain combustor. Such combustors are potentially suitable for use in gas turbines in place of conventional steady-flow combustors.
