Shortened afterburner construction for turbine engine

TLDR
An afterburner construction for a turbine engine such as a turbofan engine is foreshortened by using a construction which utilizes swirl flow phenomena to rapidly mix the engine products of combustion and coolant flow, such as fan air, while maintaining engine performance and structural part integrity as mentioned in this paper.
Abstract
An afterburner construction for a turbine engine, such as a turbofan engine, which is foreshortened by using a construction which utilizes swirl flow phenomena to rapidly mix the engine products of combustion and coolant flow, such as fan air, and/or to rapidly accomplish the afterburning combustion process in the afterburner, while maintaining engine performance and structural part integrity.

Compact swirl augmented afterburners for gas turbine engines

TL;DR: The swirl generator as discussed by the authors converts an oxidant flow into a turbulent, three-dimensional flowfield into which the fuel is introduced, and the generator is configured in a backward-flowing manner that carries heat and combustion byproducts upstream to continuously ignite a combustible fuel/oxidizer mixture in adjacent shear layers.

Bypass duct of a turbofan engine

TL;DR: In this article, the fairing element with a specific outer contour is integrated into the downstream guide vane assembly, which results in lower pressure losses and reduced fuel consumption as well as reduced pressure effect on the fan and, consequently, increased operating stability of the fan.

Compact lightweight ramjet engines incorporating swirl augmented combustion with improved performance

TL;DR: A ramjet powered device that utilizes a novel swirl generator for rapidly and efficiently atomizing, vaporizing, as necessary, and mixing a fuel into an oxidant is described in this article, where a toroidal outer recirculation zone and an inner central recirculating zone are configured in a backward-flowing manner that carries heat and combustion byproducts upstream where they are employed to continuously ignite a combustible fuel/oxidizer mixture in adjacent shear layers and stabilizes flame propagation and accelerates combustion throughout the entire combustor.
