This paper summarizes the design and development of a fault tolerant linear electromechanical actuator for the lower stage thrust vector control of a satellite launch vehicle. Power electronics and electric machine technologies have evolved to the point that high-power electromechanical actuators present a viable alternative in applications historically served by hydraulic devices. In selecting...

A new approach is proposed incorporating heuristic optimization algorithm with a switch to a local search algorithm for the multidisciplinary design of solid launch vehicle at conceptual level. Heuristic optimization algorithms such as Genetic Algorithm often may locate near optimum solutions at the expense of large function evaluations. Local search algorithms including both gradient and non g...

* Member ASME ABSTRACT The vibro-acoustic environment inside a launch vehicle payload fairing is extremely violent resulting in excessive development costs for satellites and other payloads. The development of smart structures and active noise and vibration control technologies promised to revolutionize the design, construction and, most importantly, the acoustic environment within these fairin...

The Orion capsule, the successor of the Space Shuttle as NASA’s flagship human transportation vehicle, is designed to take men back to the Moon and beyond. The first Exploration Mission (EM1) is scheduled for 2018, while its first flight test, EFT-1 (Exploration Flight Test-1), was successfully completed on December 5th, 2014. The main objective of the test was to demonstrate the capability to ...

Information and communication technologies (ICT) play significant role in modern smart grids (SG). SG functionalities require implementation of devices with computing performance into the grids and communication network between these devices. This has also been the case in a low-voltage direct current (LVDC) electricity distribution system, to which remote and automated grid monitoring and cont...
