Fluidic Thrust Vectoring for Low Observable Air Vehicles
2nd AIAA Flow Control Conference, 2004An experimental investigation into fluidic thrust vectoring technology has been conducted at the Goldstein Research Laboratory, University of Manchester, UK. Pitch only thrust vectoring of the primary exhaust jet was achieved by using tangential injection of a secondary control jet - the coflow technique.

Fluidic Thrust Vectoring of Engine Nozzle
2018Fluidic thrust vectoring is an ability of air vehicles to manipulate the nozzle flow which helps in deflecting their longitudinal axis. This type of vectoring overcomes the use of mechanical actuators for controlling the nozzle, thereby giving an efficient performance and reduction in weight.

Jet thrust vectoring using a miniature fluidic oscillator
The Aeronautical Journal, 2005AbstractThis paper presents a new approach to vectoring jet thrust using a miniature fluidic actuator that provided spatially distributed mass addition. The fluidic actuators used had no moving parts and produced oscillatory flow with a square wave form at frequencies up to 1·6kHz.

A numerical method for the study of fluidic thrust-vectoring
Advances in aircraft and spacecraft science, 2016Thrust Vectoring is a dynamic feature that offers many benefits in terms of maneuverability and control effectiveness. Thrust vectoring capabilities make the satisfaction of take-off and landing requirements easier. Moreover, it can be a valuable control effector at low dynamic pressures, where traditional aerodynamic controls are less effective.

Evaluation of fluidic thrust vectoring nozzle via thrust pitching angle and thrust pitching moment
Shock Waves, 2016Shock vector control (SVC) in a converging–diverging nozzle with a rectangular cross-section is discussed as a fluidic thrust vectoring (FTV) method. The interaction between the primary nozzle flow and the secondary jet is examined using experiments and numerical simulations.

Computational and experimental investigation of fluidic thrust vectoring actuator
Journal of the Brazilian Society of Mechanical Sciences and Engineering, 2018Fluidic thrust vectoring (FTV) control is an innovative technique employed to affect the pitch control of an air vehicle or an unmanned air vehicle in the absence of conventional control surfaces such as elevators. The main motivation in using FTV is to render the aircraft low observable.
