Fluidic Thrust Vectoring of Engine Nozzle
Fluidic 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. Single axis limits the nozzle thrust only in the vertical direction capable of complimenting the horizontal control surface giving pitching motion, whereas multiple axes give rise to horizontal and vertical direction giving pitch and roll/yaw motion. The source for the secondary injection is taken from the compressor and acts as a barrier to deflect the main flow to the desired direction. The primary objective of this project is to design a nozzle in ANSYS 15.0 with pressure inlets at three junctions after the throat section and with the boundary conditions applied to the front and back end of the nozzle; the thrust produced is found out at an angle to which the main fluid flow is deflected with a secondary fluid flow of pressure inlets at the exhaust of the nozzle.
