The present work is an attempt to create the concept of an engine that will combine the benefits of a pulse powered piston engine and continuously powered turbine engine. The paper focuses on the subject of pressure gain combustion (PGC). A turbine engine concept with stationary constant volume combustors, working according the Humphrey cycle, is presented. Its work has to be controlled by valve timing system. Four different valve timing concepts were analyzed. Their influence on thermodynamic performance of engine was evaluated. Different valve constructions were researched by means of 3D numerical computational fluid dynamics (CFD) simulation.
