A Thrust Vector Control Jet Nozzle for Submersible Vehicles

Synthetic Jet Thrust Optimization for Application in Underwater Vehicles

Zero-mass pulsatile jets are proposed for low speed maneuvering and station keeping of small underwater vehicles. The flow field of such jets are initially dominated by vortex ring formation. Such pulsatile jets can be actuated through a variety of techniques. Two prototypes of such actuators, presented here, include a mechanical plunger system and a solenoid actuator. The actuators consist of ...

effects of divergence angle on moveable nozzle performance in thrust vector control system

in this paper, by numerical simulation of gas flow, effects of divergence angles on the amplification factor, side force and thrust vector magnitude of a moveable nozzle with supersonic split line have been investigated. the study is conducted for constant exit to throat area ratio and the location of the split line is also constant. the finite volume method with second order upwind scheme for ...

Thrust Vector Control Robustness of axial-symmetric Launch Vehicles with Fuel Slosh

Clearance of Thrust Vector Control (TVC) laws for launchers demands the capability to provide analytical certificates for the system’s robust stability. During exo-atmospheric flight, a key role is played by the ability to deal with non rigid-body effects such as fuel sloshing. Depending on its frequency and magnitude, sloshing can easily deteriorate the performance of the TVC laws to the point...
