When the engine is in this position the rotor arm "F" will point directly to the sector in the distributor cap to which number one spark plug cable is connected.
Coat rotor cam "A" with a thin film of vaseline every 2000 miles.
The pressure acting upon the exposed faces of the rows of vanes would crowd the rotor to the left.
The turbine rotor itself has scarcely any end thrust, so that all the thrust bearing has to do is to maintain the above-prescribed adjustment.
By means of these liners the rotor may be set in its proper running position relative to the stator.
Remove the liners from under one bearing pad and place them under the opposite pad until a blade touch is obtained by turning the rotor over by hand.
The blades are then set into grooves cut into the rotor drum or the concave surface of the casing, and spacing or packing pieces C (Fig.
Third, the lay shaft driving the governor oil pump and reciprocator is located underneath the main turbine shaft, so that the rotor may be readily removed without in the least disturbing the governor adjustment.
The position of the rotor is then so adjusted that the radial blade clearance is equalized when the turbine is at operating temperature.
This is a plan view showing the rotor resting in position in the lower half of its casing.
A photograph of the rotor R R R is reproduced in Fig.
The upper screw S{2} is set so that when the rotor exerts a light pressure against it through the thrust block and lever the grooves in the balance pistons are just unable to come in contact with the dummy strips in the cylinder.
These dummy pistons are shown at the near end of the rotor in Fig.
Main Bearings The bearings which support the rotor are shown at F F in Fig.
Between the rows of the blading upon the rotor extend similar rows of stationary blades attached to the casing or stator.
When the rotor plates are revolving the centrifugal force keeps the water pressed toward the circumference of the drum, and the friction at any speed is dependent on the area of the rotor plates in contact with the water.
The rotor plates do not touch the stator plates in the dynamometers, but drag on the water with which the drums are partially filled, and thus tend to cause the drums to revolve around with them.
As the friction of the rotor plates on the water heats it in exact proportion to the amount of power absorbed, the small amount of water in the drums would be soon converted into steam unless continually renewed or cooled.
The principle is simply to allow steam at a high pressure to impinge upon blades fitted to a rotor which it revolves on the principle of the syren.
The steam is afterwards used expansively in a second rotor working directly upon the screw shaft.

All right, he told himself, the dial on the right side of the panel is rotor speed.
Well, remember one thing--the downdraft from the main rotor is going to buffet you like crazy.
In many motors (especially small ones which are started unloaded) the rotor winding consists of a series of copper bars brazed to solid end-rings at each end of the core, thus forming a permanently short-circuited winding.
The rotor circuits are, therefore, closed upon themselves in normal operation.
These motors are in general appearance similar to the induction motor, but the rotor is fitted with a commutator.
For starting, a polyphase resistance completes the circuits of the rotor winding.
The currents in the rotor winding are induced by the action of the rotating magnetic field set up by the stator currents.
The words are self-defining; a winding is said to be revolving or stationary according as the armature forms the rotor or stator of the machine.
The entire structure or rotor consists of a shaft, hub or spider, field magnets and slip rings.
By giving liberal thickness to the rim of the spider, the rotor then answers the purpose of a fly wheel, hence no separate fly wheel is required.
How does a turbine rotor differ from the ordinary construction?
How is the design of the rotor modified so as to reduce the centrifugal force?
In these machines, the rotating magnet, which, with definite poles, is replaced by a rotor having closed circuits.
The secondary core has only two slots containing a single coil, while the rotor or primary core has four slots.
The rotor flanges, both top and bottom, are provided with discs which are turned in alignment with the punchings, and these discs bear against the top and bottom flanges between which the secondary punchings are clamped.
Yet exact quadrature is necessary to make the strength of the resultant field, and consequently the rotor speed, proportional to the power factor, as explained in the discussion of the field producing element.
The regulator being two pole, the rotor is turned through an angle of 180 deg.
This gear train is driven directly by the rotor and therefore its friction should be low and constant.
The secondary is built up in a short skeleton frame with brackets for the rotor bearings bolted to the frame and the top cover bolted to the top brackets.
Flexible leads are brought out from the rotor and twisted around the shaft as in standard regulator practice.
This has the effect of reducing the resistance of the rotor winding to some extent and causing the motor to have less slip with a given load.
The four commencing ends are connected together on one side of the rotor and the four finishing ends are soldered together on the other.
The rotor is made of laminations cut from sheet iron, as shown in Fig.

I'll disengage the main rotor once we're on the ground.
By the time I managed to fight my way through the spray, the rotor was on full power and Alan Dupre and his Bell were already lifting off.
I started dashing back, but now the main rotor was creating a powerful downdraft, throwing the rain into me like a monsoon.
As we settled in, the rotor began to cause surface effect, throwing a spray off the paving stones, which now glistened under the cold beam of the landing lights.
Then I sensed the mainrotor engage, a sudden "whoom, whoom, whoom" quickly spiraling upward in frequency.
A thrust bearing, consisting of roller bearings and running between hardened steel face washers located at either end of the main bearings is provided solely for centering the rotor so as to equalize the clearance.
Now if the rotative speed be taken only half as great, the maximum diameter of the rotor may be doubled and, without increasing the height of the blades, the capacity of the turbine will be doubled.
The annular diameter or space between the rotor and the stator is gradually increased from inlet to exhaust, the blades being made longer in each ring.
When the mechanical limit is reached, the diameter of the rotor is increased as at I and D so as to keep the length of blade within bound.
Similar results are secured making a double flow turbine which is in effect, as will be seen from the figure, two single flow turbines made up in a single rotor in a single casing with a common inlet and two exhausts.
This method may also be used with satisfactory results on large three phase motors of the wound rotor type.
Now its rotor blades were clawing the air, askew, while it circled downward like a wounded bird.
The shaft of a little one twelfth horsepower motor adjoining was connected with the rotor through the centre of the casing.
The steel casing of the rotor naturally gives the steam the circular course of the disks, and as it travels around the disks the vapour adheres to them, and the particles of steam adhere to each other.
Additionally, a helicopter must not land too close to a decontamination station (especially upwind) because any trace of contaminants in the rotor wash will compromise the decontamination procedure.

On motors of more than 2 horse power capacity a ventilating fan is attached to the rotor which provides a continuous supply of cool air while the motor is in operation.
The bearing brackets are of rigid mechanical construction, and the pulley end bracket and bearings of all sizes are split to facilitate removal of the rotor and complete inspection.
Practically every one is made use of and while, of course, the action of a single particle of steam would have but a negligible effect, the vast number engaged cause the rotor to be powerfully blown round.
The ends of the rotor are smaller than the body since they are intended to fit into the bearings, and one of the ends is prolonged so as to be available for coupling to the propeller-shaft of the ship.
At each end is a bearing or support in which the rotor or moving part is held and in which it can turn freely.
Rebounding, it then comes back towards the right but quickly is caught by another guide blade and by it hurled back upon a second rotor blade, giving it a leftward push just as it did to the first.
The rotor or part which rotates is a strong steel forging shaped somewhat to follow the lines of the inside of the casing.
That causes it to rush straight at one of the blades upon the rotor against which it strikes violently, giving that blade a distinct and definite push to the left.
Connect the other end of the rotor of the variocoupler to one of the posts of the first variometer and the other post of this to one of the terminals of the detector filament.
This done connect one terminal of the tickler coil which is on the rotor of the variometer to the plate of the detector and the other terminal of the tickler to the other post of the .
By using the coil wound on the rotor of the variocoupler as the tickler the coupling between the detector tube circuits and the aerial wire system increases as the set is tuned for greater wave lengths.
The rotor of a variometer or variocoupler is a rotating coil.
The rotor is mounted on a vertical shaft in a scroll-shaped concrete chamber, something like a snail shell.
If the rotor were immovable the jets would have to change their direction in passing through the rotor, but as the rotor is free to turn, the jets react against these blades and set the wheel to revolving.
The blades of the rotor or revolving part of the turbine are oppositely curved.
Because the rotor takes care of that, after the engine is dead," explained Linda.
