Unsteady design-point performance modeling of a pulse detonation turbine engine

An unsteady overall performance model for design-point analysis is developed for a pulse detonation turbojet engine to address the strongly unsteady outlet parameters of the pulse detonation combustor (PDC) in pulse detonation turbine engines (PDTEs). The unsteady combustor outlet parameters are obtained from an analyt...

Experimental investigation of a shock divider for enhancing turbine performance under pulse detonation gas impact

Abstract To mitigate turbine performance degradation caused by the highly pulsating exhaust from a pulse detonation combustor (PDC) in pulse detonation turbine engines, a shock divider was employed in this study to regulate the detonation gas. An asymmetric dual-channel shock divider was designed and manufactured, and...

A DIMENSIONLESS DESIGN FRAMEWORK AND MECHANISTIC STUDY OF A PERFORATED-WALL TRANSVERSE-JET MIXER FOR RAPID COOLING OF HIGH-TEMPERATURE GAS STREAMS

In conventional aero-engine testing, the combustor and afterburner are usually evaluated separately, which increases cost and energy consumption because two high-temperature sources are required. This study proposes a flange-type mixer for integrated testing, in which ambient air is transversely injected to cool the...
