Through this, they determined that the noise and, perhaps the problem, was to be found in the area of the swash plate.

The collective pitch mechanism is by means of a sliding swash plate.

Movement of the swash plate controls pump output from zero to maximum.

By adjusting the swash plate in the motor, the stroke of its pistons are changed.

However, the designer's problem of lubricating the swash plate face (a sliding contact) is made even more difficult.

The washer on the swash plate stud was found installed under the nut.

Further investigation consisted of isolating the flight control actuators from the swash plate assembly.

Bruno Nagler began wind tunnel experiments into helicopter design in 1926 and developed the first practical swash plate.

The flight controls are directly linked to the swash plate of the helicopter so there are no hydraulic systems in the 269.

Reverse was produced by reversing the flow of the pump through over-centering of the swash plate.

The rotor was a semi-rigid or teetering design with a swash plate, rotating at up to 270 rpm.

While carrying out a daily inspection on aircraft 902 the maintenance crew discovered extensive damage to the rotating swash plate and scissors.

Metal rotorhead assembly from Swash Plate up.

The swash plate drive has the advantage that there is little rotational out of balance, so the principal vibration is in line with the blade.

His expertise ensured that a thorough inspection was carried out on the swash plate assembly to ensure compliance with technical orders.

The swash plate angle will remain at the maximum allowed, and the pistons will operate at full stroke.

The helicopters were later returned to service with improved swash plate duplex bearings and new warning systems for the bearings.

His detailed inspection revealed that the wrong bearing had been installed in the lower end of the pitch link, where it connects to the swash plate.

By moving the lever, the swash plate moves its attached pistons forward, thus allowing them to move within the bore and causing the motor to turn.

In variable displacement units, the cam is movable and commonly referred to as a swash plate, yoke or hanger.

He switched his aiming point to the swash plate on top of the chopper's whirling mainshaft, and tracked the aircraft's gradual descent.

Another method of drawing pistons up the cylinder is to attach the cylinder heads to the surface of the swash plate.

When the appropriate button is pushed, the ECU commands the control motor to move the swash plate to the next higher or lower preset position.

Upon visual inspection of the area, it was discovered that a swash plate seal had become detached and was encircling the main rotor mast.

Hence both quantity & direction can be varied in a radial piston pump, just as in the Swash plate pump.

A swashplate at one end is connected to the pistons.

A swashplate consists of a disk attached to a shaft.

Other swashplate and control design have been used.

The swashplate moves up and down, along the main shaft, to change the pitch of both blades.

Hydraulic motors, particularly the swashplate form, are widely and successfully used.

Older model helicopters use three independent servos to manipulate the swashplate.

The collective blade setting is mostly achieved through vertical movement of the swashplate.

As each blade crosses the highest point of the swashplate, it generates more lift.

Tilt and Roll is controlled by tilting the swashplate assembly.

A swashplate controls the collective and cyclic pitch of the main blades.

If the swashplate is perpendicular to the axis of rotation, no fluid will flow.

The engine is often incorrectly referred to as a swashplate engine.

Most cheaper models do not have a swashplate, but instead use a third rotor on the tail to provide pitch control.

Before the development of high performance bearing materials, the cam and swashplate engines appeared to offer some advantages.

The most common is the swashplate pump.

Systems which employ two pushrods to the swashplate (one in front and one behind) are the ones to look for.

Like a conventional helicopter, altitude is controlled by raising or lowering the swashplate assembly.

Conventionally, the entire swashplate is moved along the mainshaft by a separate actuator.

This uses a bearing that purely nutates, rather than also rotating as for the swashplate.

A similar idea was the swashplate engine, an axial form of cam engine.

In engineering, a nutating motion is similar to that seen in a swashplate mechanism.

The swashplate, which is a combination of plastic and metal parts, is slid down the mast.

The pitch and roll control algorithms have to recalculate a new swashplate position every 10 milliseconds.

In 1917 Anthony Michell obtained patents for his swashplate engine design.

The rotating swashplate is connected to the pitch horns by the pitch links.
