Some CT based generators have 2 gas turbines, axially in-line, with a double ended generator/alternator centered between them. The Pratt & Whitney model calls this a Twin-Pac. In this arrangement one Free Turbine requires a clockwise rotation, and the other Free Turbine requires a counter-clockwise rotation. Both may be coupled directly to the generator or via an over-running clutch for synchronous condenser operations.

What can happen if a wind turbine is free wheeling?
Wind Turbines control system controls Pitch of blades to maintain optimum speed in all wind conditions, if wind is too fast, turbine's brakes will be automatically engaged to slow it down or even stop it in case of storms, if the brakes or control system fails, it will rotate freely and ultimately breakdown under stress from large centrifugal forces.
Did LEster Alan Pelton invent the water turbine?
Pelton invented a free jet water turbine called the Pelton wheel or Pelton turbine
What happens to a wave when it hits a free boundary?
When a wave hits a free boundary, it reflects back in the opposite direction. The wave's amplitude and phase may change depending on the nature of the boundary.
What are the advantages of free turbine engine over gas turbine engine?
A gas turbine engine will usually yield more power by weight than a piston engine. Main downside is that it can't be throttled very well. Energy efficiency isn't all that good to start with, and will drop right down if it has to be operated outside its optimum range.
What are the advantages of having a wind turbine?
that wind is free :D
What is the opposite of the word slave?
free-man, free-woman
How do you rotate a picture in paint?
In order to rotate images in Pixlr, you will need to go to "edit". Then, you will need to go to "editor" and click on "free transform". You can then drag the mouse in either direction to rotate the picture.
When drawing a free body diagram for an object on an inclined surface which way does the friction force point?
if in gravity environment it points opposite to the direction it wants to move. That is the force is uphill, parallel to the inclined surface. due to applied force. Under an applied force, again, it points opposite to the direction it wants to move
How does a compass utilize magnetism to indicate direction?
A compass utilizes magnetism to indicate direction by aligning itself with the Earth's magnetic field. The needle inside the compass is a magnet that is free to rotate, and it points towards the Earth's magnetic north pole. This allows the compass to show the direction of north, south, east, and west based on the orientation of the needle.
What is the opposite of free market?
A free market economy
A magnet free to rotate becomes what?
A compass, because the magnet's North pole will rotate until it points to the Earth's North pole.
What is the opposite of capture?
The opposite transitive action of capture is "release." (free, let go)
