Airbreathing hypersonic systems offer distinct performance advantages over rocket-based systems for space access vehicles. However, these performance advantages are dependent upon advances in current state-of-the-art technologies in many areas such as ram/scramjet propulsion integration, high temperature materials, aero-elastic structures, thermal protection systems, transition to hypersonics a...

Control of Underwater vehicle manipulator systems (UVMS) are limited to human intervened tele operation in almost all practical applications. Extending these missions to autonomous or semi autonomous operation requires accurate dynamic modeling of the system. Such modeling assists system design and controller testing of autonomous UVMS. The study performs a dynamic analysis to capture relative ...

This work shows a linearization for a AUV-Cormoran dynamic mathematical model with the aim of designing linear controllers for trajectory control. The model is developed under 3 degrees of freedom and the whole system has been simulated in Matlab Simulink environment. The linearization model is based on understanding the dynamics of the vehicle under different operating speeds, which present a ...

an autonomous underwater vehicle (auv) with less noise and vortices as well as efficient power consumption, is pursued in this research by inspiration of shark swimming. design, hydrodynamic analysis, modeling, fabrication, navigation, and control of this novel auv is the main goal of this research. detailed explanation of the test and experiment with a brief overview on fabrication are provide...

Underwater vehicle-manipulator (UVM) systems have been suggested for inspection, maintenance, repair and construction of underwater structures. The addition of manipulators to the vehicle makes control of the system more difficult due to the interaction forces between vehicle and manipulator. So, the efficient compensation of those interactions should be considered for accurate control of both ...

A preliminary study on the role of torque feedback in the steering wheel was conducted on the Clio dynamic driving simulator at RENAULT. An experiment comparing different torque feedback strategies was conducted to evaluate the potential of driving simulators in the study of future steer-by-wire systems. The results indicate that drivers on the simulator can control their vehicles in curves wit...

Real-time cooperation between autonomous vehicles can enable time-critical missions such as tracking and pursuit of a dynamic target or environmental feature, but relies on wireless communications. Underwater, communication over distances beyond about one hundred meters is almost exclusively accomplished through acoustics, which bring challenges such as propagation delays, low data rates, packe...
