allows climbing to control the flight of the helicopter. Modern versions distinguish high angle of roll and place. To find out more information about the climbing board, it is necessary to consider the existing devices.
The working principle of the clamshell built on changing the position of the screws. This process is performed by changing the angle struts worn. Lower ring responsible for stabilizing rod. To control the helicopter sticking behind pillars use. the inclination angle of them is limited. The lifting of power from the helicopter is controlled by the A-pillars. Smooth rotation of the blades was provided by spherical bearings. But in this case, a lot depends on the type of change.
IMPROVISED EDITS
Making climbing helicopter with their hands is difficult. Mainly required for the assembly of a wide ring 25 cm in diameter. The hinges should be at the bottom of the structure. The screws are fixed in the board. It will use the welding machine. Furthermore, around the clattering helicopter with their hands, harvested make wheel bearing. The rotating ring applied in simple changes of small diameter.
Spherical bearings at the same time are not often used. Cyclic inclination of the blades depends on the size of the shelf. After fixation, the plates can install the front legs. Then, after the climbing board collected with his hands, fasten hinges, which fit under the support plate. change chord wise blade should not touch the ball joint. The average angle slope of 30 degrees.
CLIMBING TIPES
The first section of machines is carried out by the number of blades carried. Trilobate device usually installed with the double rings. Changes on the four blades are considered to be more common. Transient changes are characterized by wide bowls in a lower portion of the structure. Also noteworthy is that there are cracked changes and devices with impeller. In a separate category marked running changes, which are used in gyroplanes.
CHANGES TO THE THREE SCREWS
Model three screws are ideal for helicopters. Carrying shelves are used in different sizes. The diameter of the lower ring is usually no more than 22 cm. Many changes using a few plates. pitch control is carried out via the front push. spherical type bearings are often used in machines.
Direct fixed plate can be installed under the ring, or above it. Many models of the screws fastened by the shelves. Deviation plates in this case depend on the size of the door posts. Fixation of angles is determined by the shape of plates. Buses often located in the lower part of the structure. The disadvantage of the devices on the three blades is considered to be a small cyclic sting.
MODELS ON THE FOUR SCREWS
Devices on the four blades are generally produced with a cam mechanism. Many changes the angle of pitch no more than 40 degrees. Problems with controlled tilt rotors. If you are the experts, the change with double buses is rare. Rotating rings of different sizes have been introduced.
Many experts believe that the spherical type of bearings prove. Many models use blockers to stand up. Thus, the slope in the rolling machine is very limited. Problems with warp change are not terrible. Mounted change mainly by hinges.
ADAPTERS
Transition machines are widely used in helicopters from various manufacturers. If you believe the experts, then the benefits of devices should be classified stability. The slope of the blade is regulated only by the front legs. If we believe that those skilled in the art are allowed to use a small diameter. The limitation of angle of pitch in these types of changes is equal to 35 degrees.
Carrying in machines is commonly used spherical type. When this lining under them is very rare. Separately, it is important to note that there are changes for gyroplanes. Shelves used an elongated shape. Plates are often fixed on top of the mechanism. The cyclic slope of the blades depends on a fixed ring sizes. Block at the bar often. Across the plate are sleeves that protect the blades.
CHANGE COAXIAL WITH THE IMPELLER
Coaxial climbing impeller for konvertoplanov. Traction for models is very high. If you consider the experts, use the short length of the shelf. Installation was carried out on plates bearing. Modifications with large adapters are very rare. The inclination angle of the screw pitch is generally less than 40 degrees. Many automatic locks are missing. Installation standard devices carried over the rotor. In this case, the sleeves are put down in two stacks.
Fans are used with flap mounting located in the lower part of the structure. According to experts, the traction of changes depends on the diameter of the plates. The cyclic slope of the blades is closely related to the size of shelves attached to the sides of plates with fixed rings. spherical type bearings in machines with impeller are very common. Many experts argue that the changes suffer deflection plates. The slope in the roll devices is extremely limited.
ARTICULATES UNITY
Expressed changes have helicopters are rare. Trapping power they have, as a rule, is at a high level. When we talk about the shortcomings, it is important to mention the complex handling mechanism with strong gusts of wind. If you consider the experts, the rotors should be located in the upper part of the change. To solve the problems with slanted plates installed lock. Direct pillars fixed on the board.
Limitation of pitch angle is about 40 degrees. Many changes were made without spherical bearings. Plates used with or without overlays. Modifications with movable rings are rare. Torque against high plates. Shelves of small width used for fastening. The inner rings have changes of this range can withstand heavy loads. It is also noteworthy that the market offered changes to the lower position of the rotors. In this case, the counter uses small height and is mounted under the tray.
According to experts, the power of repair in the machines of this series is very high. For modern versions, they fit very well. But the disadvantages of such systems are also worth considering. First of all - it's a small corner of the slope. On spherical bearings have a greater load. roll reaches a maximum slope of 50 degrees. Lock shelves are used very rarely. Set of machine of this type was carried out only on the rotors via hinges.
DRIVING DEVICE
Running machines will report the fact that it can be used in helicopters and on convertoplanov. Many changes apply to the long legs and the wide plate. Rotors are usually located in the upper part of the machine. Tilt batting surface in this case depends on the width of the movable ring. Problems with tilting screws have changes occur very rarely.
Protective sleeve installed over adapter. Mounting of the rotor is only through the hinges. In which the inner rings are often used small diameter. The main load in mechanisms is exactly on the shelf. Cyclic slope of the blades in the not too high. It is also noteworthy that the modifications of this type are distinguished quality blockers. Ball joints on machines are very rare.
CHANGE SIKORSKI
Climbing Sikorsky is a reliable and durable various shelves. Plates provided in this case by 23 cm. According to experts, the problem with the slope in pitch rarely occurs. The rotors have the model is higher than the plates. The installation of the vertical is very fast. Many experts believe that the adjustment of the role takes place very smoothly. This effect is achieved by installing a small shelves. Limitation of pitch angle equal to 40 degrees.
Ball joints used with overlays. Experts say that the blockers stretch in this case, working well. The disadvantage of change is considered to be a small torque. Ring devices wear out fairly quickly. Special attention deserves the changes in the hinges. They are located in the lower part of the structure. Deviation plates are therefore simply regulated.
FEATURES OF THE MODEL SERIES MI 8T
This climbing board screws used on helicopters of various series. Rotors set at the ring. climbing works by changing the position of the blades. If you believe the experts, the ball bearings can withstand heavy loads. In this case, the cyclic pitch is perfectly controlled. at the machine bearings are spherical type. Stop wearing when tilting rarely occurs.
In this case, the wear rings have a very small. Individual attention, compact hinges. In a modification of the rotor is set very tight. Circular movements are performed smoothly, the carriers of the load are evenly distributed. Limit of tilt field is 30 degrees. Many experts believe that the plates and at high speeds stabilize too quickly. Separately, it is important to note that the maximum slope of the roll does not exceed 20 degrees.
A SERIES OF CHANGES TO THE PARAMETERS OF THE AB-1
Presented climbing phases characterized by low pillars. Limitation of tilt batting surface in this case is 50 degrees. push bearings apply to the plates. If you are the experts, the problem with the closing rack is very rare. Plate in this case fixed at 23 cm. Rotors have changes are above tray level. Cover in this case can last for a long time.
Deviation plate control at a good level. Cyclic blade pierces custom sole pillar. The slope of the roll is 30 degrees. Installing vertical runs fairly quickly. spherical type bearings are located just across the board.
THE DIFFERENCES BETWEEN THE DEVICES 912
Climbing offered series stands a good adapter. This device is a cam mechanism. But attachment hinges have changes at the bottom of change. Bearings are only on a plate. Installing the blades vertically long time it does not take away. The limitation of the inclination angle of the roll is 25 degrees. Many experts believe that the device has an excellent stabilization. Also noteworthy is that the rotating rings use with a diameter of 34 cm.
Protective sleeves are only on the A-pillars. The limitation of the roll angle does not exceed 55 degrees. Precoc problems with this machine are terrible. Attachment change to the rotor by standard joints. Many experts point out that the adjustment of the blades horizontally very quickly. Do not close the shelf, the model.
