A REPORT ON AUTOMATION OF CONVERTOR TILTING DRIVE USING PLC AND VVVF DRIVES Abstract: Industry is a home of various kinds of machines that are used for numerous processes and treatments. The control and working of these machines have been automated through the use of PLCs. Automation has resulted in faster production rate‚ increased accuracy‚ better quality and reduced faults and human errors. PLCs and VVVF drives are used in most of the sections and units at VISL because of their simple methods

after sunrise‚ the USS Vincennes moved itself north to investigate "sounds of explosions" as reported by the USS Elmer Montgomery. However‚ this command decision by CAPT Rogers was in direct contrast to his received order‚ which was to send his helicopter 40 miles north to investigate and keep the ship safely out of range of any possible action. Instead‚ CAPT Rogers’ ship found several Iranian gunboats

During my time as PR manager at Greenergy a rotor blade fell off of a wind turbine; this incident caused injuries to a few members of the public. The Marketing Manager and CEO each confided in me that they wanted the incident to be kept quiet and leaked outside of the company. While their opinion

A direct current (DC) motor is a fairly simple electric motor that uses electricity and amagnetic field to produce torque‚ which turns the motor. At its most simple‚ a DC motorrequires two magnets of opposite polarity and an electric coil‚ which acts as an electromagnet. The repellent and attractive electromagnetic forces of the magnets provide the torque that causes the DC motor to turn. If you’ve ever played with magnets‚ you know that they are polarized‚ with a positive and a negative side. The

question about the new version of the Hellfire missile being deployed with the UAV. Then I couldn’t resist putting on the Native American issues hat and asking about where they had come up with Gray Eagle. Traditionally‚ the service has given their helicopters names based on tribes or famous chiefs. I was not familiar with Chief Gray Eagle‚ I said. For the two officers responding‚ it was clearly a question out of left field. They didn’t have a clear answer. Here’s a slightly edited transcript. Army officer:

Introduction One of the most common causes of fatal helicopter accidents is Controlled Flight Into Terrain (CFIT) at night. (FlightWeb). The major contributor to such accidents is the pilot ’s level of situational awareness‚ or rather not being able to see where they are going‚ or what might be in the way of unobstructed flight. As helicopters are routinely used in low-altitude missions they are frequently required to fly in close proximity to trees‚ power lines‚ telephone poles‚ etc. As

The other one is called a helicopter parent‚ which is a parent who is too involved in their child’s life‚ education‚ and upbringing.

Born-Oppenheimer approximation. E=EVIB+EROT= Ev+EJ (1) Now each of the separate energies can be modeled independently. The rotational energy of the molecule can be modeled as a rigid rotor‚ which treats molecules as fixed masses on a spinning bar. The exact expression of rotational energy levels for rigid rotors can be obtained by solving the Schrödinger
