Helicopter training for Zhuhai civilian helicopters is charged on a daily basis

Description :

　　Helicopter rental has many advantages that other aircraft find difficult or impossible to achieve, and is widely used. Due to its ability to take off and land vertically without the need for large airports, helicopters are mainly used for tourism, fire rescue, maritime first aid, anti smuggling and anti drug, firefighting, commercial transportation, rescue, communication, as well as spraying pesticides to eliminate pests, detecting resources, and other sectors of the national economy. The global helicopter fleet is gradually growing.

　　Helicopter rental - Working principle of helicopter:

　　1、 Single rotor type:

　　The helicopter engine drives the rotor to provide lift, lifting the helicopter in the air. The main engine of a single rotor helicopter also outputs power to the small propeller at the tail. The onboard gyroscope can detect the helicopter's rotation angle and provide feedback to the tail rotor. By adjusting the pitch of the small propeller, it can counteract the reaction force generated by the large propeller at different speeds. Twin rotor helicopters typically use relative rotor reversal to counteract the unbalanced lift generated by the rotors.

　　Firstly, the helicopter needs to take off before it can move forward, backward, left, and right. Therefore, it is necessary to make the tilting plate in the picture move upward as a whole. The two blade clamps will have a certain angle, so clockwise rotation will have a downward force, and the aircraft will take off. However, at this time, the lift generated by the left and right rotors is the same, so the helicopter can only move upward. If the tilting plate is regarded as a dial, if it tilts forward, the upper half of the tilting plate will rotate. Then the two connecting rods will only have a difference in direction between 12 o'clock and 6 o'clock (one up and one down). The pull rod at 6 o'clock will push the blade clamp upward, so the downward force generated by the original angle of the rotating wing will increase. The downward pull at 12 o'clock will reduce the angle of the rotor, so it will move downward. As the force decreases, the two rotors are no longer balanced, and the force on the right side is greater. If the force on the left is small, the helicopter should fly to the left, but the rotating rotor follows the gyroscopic effect and needs to turn 90 degrees clockwise to produce the effect. Therefore, the force on the rotor in the 6 o'clock direction is greater than that in the 12 o'clock direction, so the helicopter flies forward. The same applies to other directions.

　　2、 Double rotor type:

　　There are two types of twin rotor helicopters, one is coaxial twin rotor, which means that two rotors have the same axis, such as the production of the Ka-27 helicopter; Another type is the split axis twin rotor, which means that the two rotors are relatively far apart and each has its own axis. The typical representative is the American Chinook helicopter. Twin rotor helicopters can also be classified into longitudinal twin rotor helicopters, transverse twin rotor helicopters, and transverse crossed twin rotor helicopters based on the relative position of the two rotor shafts.

　　By using a mechanism called the "tilt disk", the blade angle of the helicopter's rotor can be changed, thereby achieving periodic pitch variation of the rotor. This changes the lift at different positions of the rotor rotation plane to change the helicopter's flight attitude, and then changes the flight direction by changing the direction of lift. At the same time, after the helicopter takes off, the engine is maintained at a relatively stable speed, and the control of the helicopter's ascent and descent is achieved by adjusting the total pitch of the rotor to obtain different total lift. Therefore, the helicopter achieves vertical takeoff and landing.

　　Airplane Home adheres to the service standards of the new era of general aviation, closely linking the aviation industry with daily life, leisure, and striving to serve the public and realize the dream of free flight for millions of Chinese people throughout their lives.
