TLDR
In this paper, a ready-made central strut-based rocket-based combined-cycle (RBCC) engine was numerically investigated in the ejector mode, and the flow features and operation characteristics in the RBCC inlet were strongly correlated with the flight conditions, inlet configuration, and operation of the embedded rocket.About:

Survey on key techniques of rocket-based combined-cycle engine in ejector mode
TL;DR: This study aims to provide a summary report on the recent research progress on the RBCC engine in ejector mode from four aspects, namely the combustion organization, the mixing enhancement, the resistance to backpressure and the ejector/ramjet mode transition.

Experimental study on ejector-to-ramjet mode transition in a divergent kerosene-fueled RBCC combustor with low total temperature inflow
TL;DR: In this paper, a divergent JP-10-fueled RBCC combustor was tested with two different rocket control methods, in terms of switching off (switching off) and progressive (maintaining a significant reduction in the mass flow rate).
Journal ArticleDOI
Research progress on ejector mode of rocket-based combined-cycle engines
TL;DR: A number of relevant key technologies regarding the study of the ejector mode are proposed, including efficient ejection, efficient mixing and combustion, widely adjustable rocket, widely applicable variable geometry inlet/nozzle design and control, multi-mode flow passage design, and robust mode transition.

Effect of the heat release on the component coordination in the rocket-based combined cycle engine
TL;DR: In this paper, the effect of the heat release distribution on the component matching is analyzed on an integrated rocket-based combined cycle (RBCC) model through three-dimensional numerical simulations and the freejet tests under Ma∞ = 4 and Ma∩∞=5 conditions, and the results indicate that the increasing precombustion shock strength during the movement can balance the pressure difference between air intake and combustion effectively.

Numerical investigation on flow and mixing characteristics inside a converging-diverging mixing duct of rocket-based combined-cycle engine in ejector mode
TL;DR: In this article, the effects of the mixer geometry including the contraction ratio, the throat position of mixer and the converging angle on the flow structures and mixing characteristics in a converging-diverging mixing duct under no backpressure condition were numerically investigated.

Aerodynamic Performance Analysis of a Hypersonic Inlet Isolator Using Computation and Experiment
TL;DR: In this paper, a two-dimensional mixed compression inlet model with a subsequent isolator section is tested under Mach 4 and 5 flight conditions, and different configurations of the isolator are assessed with respect to their compression efficiency.

Maximum thrust for the rocket-ejector mode of the hydrogen fueled rocket-based combined cycle engine
TL;DR: In this paper, an idealized thermodynamic cycle analysis is carried out to evaluate the thrust performance of the RBCC engine for the saturated supersonic regime, and the authors show that the engine thrust grows asymptotically with ejecting ratio, then reaches a maximum, and finally reduces rapidly for a given primary stream conditions.
