aerospace applications of power electronics ppt

Abstract

Power electronics technologies play a vital role in the aerospace industry in the years to come and all emerging technologies are already an important part of the industry either at R&D or in many cases production level. It is recognised that aerospace engineering and avionics students need to be aware of these technologies and in a position to work as a team member with development of power electronics technologies addressing specific needs. The paper discusses pioneering initiatives u ....etc

The aerospace applications for nanotechnology include high strength, low weight
composites, improved electronics and displays with low power consumption, variety of
physical sensors, multifunctional materials with embedded sensors, large surface area
materials and novel filters and membranes for air purification, nanomaterials in tires
and brakes, logic and memory chips, sensors, catalyst support, adsorption media, actuators, etc.

The Carbon nanotubes(CNT) are the most important of these. These are configurationally equivalent to a two- ....etc

Aerospace Flywheel Development
Presently, energy storage on the Space Station and satellites is accomplished using chemical batteries; most commonly nickel hydrogen or nickel cadmium. A flywheel energy storage system is an alternative technology that is being considered for future space missions. Flywheels offer the advantage of a longer lifetime, higher efficiency and a greater depth of discharge than batteries. A flywheel energy storage system is being considered as a replacement for the traditional electrochemical battery system in spacecra ....etc

The main components of the flywheel energy storage system are the composite rotor, motor/generator, magnetic bearings, touchdown bearings, and vacuum housing. The flywheel system is designed for 364 watt-hours of energy storage at 60,000 rpm and uses active magnetic bearings to provide a long-life, low-loss suspension of the rotating mass. The upper bearing of the unit is a combination magnetic bearing, providing suspension axially as well as radically. The lower magnetic bearing suspends the shaft in the radial direction only. At each end of t ....etc

A flywheel is a big circular mass to store energy when in the form of rotational kinetic energy slowly added to it by intermittent torque, generally in a internal combustion engine Pistons . Once the wheel starts rotating its intertia will keep the Rytham. To give an anology just take a solid disk suspended on its center with frictionless support and attach a crack leaver at the center and try to rotate till it rotates at a constant speed. Then slowly the force on ur hand reduces now after the speed is reached if you try to added more force or ....etc

Fuel cells are a proven power source for manned spacecraft where they generate electrical power from stored hydrogen and oxygen that are carried in cryogenic liquid form. The world?s petroleum production is about to pass its peak, so a world wide development effort is being directed into adapting these high efficiency fuel cells into powering automobiles, buses and trucks. Fuel cells are more efficient than the secondary batteries used. First Alkali fuel cells are used in aircrafts, but now a days fuel cells using Proton Exchange Membrane are u ....etc
