Numerical study of secondary mass flow modulation in a Bypass Dual-Throat Nozzle [PDF]
, 2021 The fluidic thrust-vectoring modulation on a Bypass Dual-Throat Nozzle (BDTN) is studied numerically. The thrust vectoring modulation is obtained by varying the secondary mass flow, introducing different area contraction ratios of the bypass duct.

Multi-Objective Optimal Design of a Fluidic Thrust Vectoring Nozzle [PDF]
11th AIAA/ISSMO Multidisciplinary Analysis and Optimization Conference, 2006 Fluidic Thrust Vectoring (FVT) systems based on Coanda jets are amongst the most promising technologies being considered for future flapless aircraft. One of the core components of a Coanda FTV device is the main jet nozzle, featuring a circular inflow section (at the aft end of the engine) and a high aspect ratio, rectangular outflow section.

Closed-Loop Control of a Piezo-Fluidic Amplifier
, 2020 Fluidic valves based on the Coand\u{a} effect are increasingly being considered for use in aerodynamic flow control applications. A limiting factor is their variation in switching time, which often precludes their use.

Performance of a turbojet engine with fluidic thrust vectoring
The Aeronautical Journal, 2022 AbstractThe objective of the present work is to estimate the performance of a turbojet engine during Fluidic Thrust Vectoring (FTV) employed by injecting the secondary-jet at the throat of a convergent nozzle. The nozzle performance maps and effective nozzle throat area obtained from experiments are coupled with the performance of a conventional engine
