Experiments with Ejector Rocket Entrainment

Sea-Level Static Tests of Rocket–Ramjet Combined Cycle Engine Model

“…Thus, pure sea-level static test results simulating the takeoff stage were not available. There are more recent reports on ejector designs improvement by Etele et al [19], which did not include secondary injection for thrust production, so that they could not be regarded as whole engine models.…”

Supersonic Multi-Objective Optimization of a Rocket Based Combined Cycle Inlet by Differential Evolution

“…Additionally, it has been shown that a key aspect of RBCC engine performance is the air mass flow at the inlet [25]. Therefore, increasing air entrainment by utilizing an annular rocket-ejector exhaust profile has been the focus of both numerical [26] and experimental [27,28] studies. In both the simulation and experimental data, the results indicated that an annular, or semi-annular, exhaust provides superior air entrainment over a circular profile.…”
