How do swash plates work?
A swashplate is a device that translates input via the helicopter flight controls into motion of the main rotor blades. Because the main rotor blades are spinning, the swashplate is used to transmit three of the pilot’s commands from the non-rotating fuselage to the rotating rotor hub and mainblades.
How is a swash plate made?
Construction. A swashplate consists of a disk attached to a shaft. If the disk were aligned perpendicular to the shaft, then rotating the shaft would merely turn the disk with no reciprocating (or swashplate) effect. The greater the disk’s angle to the shaft, the more pronounced is this apparent linear motion.
Why is it called a swash plate?
ETYMOLOGY OF THE WORD SWASH PLATE From swash (obsolete n) an oblique figure or ornament, from aswash: see swash letter. Etymology is the study of the origin of words and their changes in structure and significance.
What does swash plate mean?
1 : a revolving circular plate set obliquely on a shaft and acting as a cam to give a reciprocating motion to a rod in a direction parallel to the shaft.
How does a swash plate compressor work?
The required amount of refrigerant gas is sucked in and compressed by changing the pressure balance within the compressor. The swash plate angle can be adjusted, which forces the piston to make larger or smaller strokes. This enables stable temperature control and improved driving feeling.
What changes the angle of the swash plate?
The swash plate angle can be changed by pivoting the yoke on pintles. The positioning of the yoke can be accomplished by manual operation, servo control or a compressor control and the maximum swash plate angle is usually limited to 17.5° (Figure 3.18).
What is the reason for swash plate compressor?
Operation. The required amount of refrigerant gas is sucked in and compressed by changing the pressure balance within the compressor. The swash plate angle can be adjusted, which forces the piston to make larger or smaller strokes. This enables stable temperature control and improved driving feeling.
What controls the angle of the swash plate in a variable swash plate compressor?
The swashplate angle is controlled with linkage and springs, which are adjusted by changing the refrigerant pressure in the compressor housing. A control valve with ports and passages that connect to the suction (low-side) and discharge (high-side) chambers of the compressor head is utilized.
What is swash angle?
The displacement of an axial piston motor is controlled by the angle of the swash plate: the greater the swash plate angle, the greater the displacement. Adjusting the swash plate angle allows the speed and torque of the final drive motor to be changed, also.
What is the reason for swash plate compressor failure in car AC?
Reason: It may be caused by a clogged expansion valve which blocks the refrigerant from flowing into the evaporator. This may also be a cause of a damaged compressor clutch that prevents the compressor to maintain the correct pressure. Or it may also be a sign of a blown fuse or leaks.
Why did my AC stop blowing cold air in my car?
The most common causes of broken air conditioning are leaks or compressor issues. If your air is blowing cool but not cold, the problem could be a clogged filter, cooling fan problem, radiator trouble, or it could simply be that you need to recharge your AC.
What temperature should car AC be?
To see if your A/C system is performing, measure the outlet temperature at the vent with an accurate thermometer. Drive the car with the A/C on “max”. With temperatures in the 70’s to 80’s Fahrenheit the outlet temperature should be around 35 to 48 degrees.
Which is a model of a swash plate mechanism?
For the Isothermal Liquid library block, see Swash Plate. The Swash Plate block is a model of a swash plate mechanism used in axial-piston hydraulic pumps and motors to convert translational motion of a piston into rotational motion of a drive shaft.
How are swashplate mechanisms used in a helicopter?
Helicopter Swashplate Mechanism. This model illustrates the operation of a swashplate mechanism used in helicopters to translate the input of helicopter flight control into the motion of the rotor blades, and hence controls the orientation of the rotor blades.
Which is the best description of a swashplate?
For a general description of the mechanism, see swashplate. A swashplate is a device that translates input via the helicopter flight controls into motion of the main rotor blades.
How is a swash plate used in a hydraulic pump?
The Swash Plate block is a model of a swash plate mechanism used in axial-piston hydraulic pumps and motors to convert translational motion of a piston into rotational motion of a drive shaft. The mechanism is a combination of a cylinder block or rotor, with the piston fitted inside, and an angled swash plate.
