Japan's smallest remote-controlled helicopter in the world

Want to know what is the smallest remote control helicopter? Let's first understand the concept and principle of helicopter.

Basic introduction of helicopter

1. helicopter English name: helicopter, which is a kind of rotary-wing aircraft with the rotor driven by power plant as the main source of lift and propulsion, and can take off and land vertically and fly back and forth, left and right. The main applied discipline is aviation science and technology (first-class discipline, Aircraft (two disciplines)). Helicopter is mainly composed of airframe, lift (including rotor and tail rotor), power and transmission system and airborne flight equipment. The rotor is generally driven by a turboshaft engine or a piston engine through a mechanical transmission system consisting of a transmission shaft and a reducer, and can also be driven by the reaction force generated by the jet from the tip of the blade. At present, there are mechanically driven single-rotor helicopters and double-rotor helicopters in actual use, of which single-rotor helicopters have the largest number.

2. Helicopter function editing.

superiority

The outstanding feature of helicopter is that it can do low altitude (a few meters above the ground), low speed (starting from hovering) and the nose direction remains unchanged, especially suitable for small-area vertical take-off and landing. Because of these characteristics, it has broad uses and development prospects. In the military field, it has been widely used in ground attack, aircraft take-off and landing, weapons delivery, logistics support, battlefield rescue, reconnaissance patrol, command and control, communication, anti-submarine mine clearance, electronic countermeasures and so on. Used for short-distance transportation, medical rescue, disaster relief and lifesaving, emergency rescue, lifting equipment, geological exploration, forest protection and fire fighting, aerial photography, etc. The transportation of people and materials between offshore oil wells and bases is an important aspect of civil use.

disadvantaged

At present, compared with airplanes, helicopters have greater vibration and noise, greater maintenance workload, higher use cost, lower speed and shorter range. The future development direction of helicopters is to improve these aspects.

3. The helicopter is edited in principle.

Single rotor type

The helicopter engine drives the rotor to provide lift and lift the helicopter into the air. The main engine of a single-rotor helicopter also outputs power to the tail.

Propeller and airborne gyroscope can detect the helicopter rotation angle and feed it back to the tail rotor. By adjusting the pitch of the small propeller, the reaction force generated by the large propeller at different speeds can be offset. Twin-rotor helicopters usually use the relative rotation of the rotor to offset the unbalanced lift generated by the rotor.

Double rotor type

There are two kinds of helicopters-twin-rotor, one is coaxial twin-rotor, that is, the two rotors are coaxial, such as Ka -27 helicopter produced in Russia; The other is split-axis twin-rotor, that is, the two rotors are far apart and each has its own axis, and the typical representative is the Chinook helicopter in the United States. Twin-rotor helicopters can also be divided into tandem twin-rotor helicopters and parallel twin-rotor helicopters according to the relative positions of the two rotor shafts.

By calling it? Tilting disk? The mechanism can change the blade angle of the helicopter rotor, so as to realize the periodic pitch change of the rotor, thus changing the lift at different positions of the rotor rotation plane to change the flight attitude of the helicopter, and then changing the lift direction to change the flight direction. At the same time, the engine keeps a relatively stable speed after the helicopter takes off, and different total lift can be obtained by adjusting the total pitch of the rotor, so that the helicopter can take off and land vertically.

4. Helicopter longitudinal system editor

The control system of a helicopter is different from that of a fixed-wing aircraft and usually consists of the following parts:

Total distance joystick

The abbreviation of pitch rod is used to control the change of rotor blade pitch. The main control lever is generally arranged on the left side of the driver's seat and rotates up and down around the axis of the bracket. When the pilot lifts the mast with his left hand, the automatic tipper rises as a whole, which increases the total pitch of the rotor blades (that is, the pitch of all blades increases by the same angle at the same time), so that the rotor tension increases, and vice versa, thus controlling the lifting motion of the helicopter. Usually, a rotating throttle control mechanism is installed on the handle of the pitch control lever to adjust the size of the engine throttle, so that the output power of the engine can adapt to the rotor power demand after the pitch of the rotor blades changes. So the joystick is also called the total throttle lever.

Periodic pitch control lever (steering lever)

Short for steering column. Similar to the steering rod of a fixed-wing aircraft, it is connected with an automatic tipping machine through a steering line system. Generally located in front of the center of the driver's seat. When the pilot manipulates the periodic pitch control lever horizontally and vertically, the automatic tilter will tilt in the corresponding direction, which will lead to the rotor tension direction tilting in the corresponding direction, so as to obtain the required propulsion force and the horizontal and vertical steering force, and then change the motion state and attitude of the helicopter.

Feet

Similar to the rudder pedal function of fixed-wing aircraft, they are all steering control tools. Because there are many kinds of helicopters, the pedals work in different ways. For a helicopter with a single rotor and a tail rotor, the pedal is connected with the pitch control device of the tail rotor through a control line system, and the lateral force generated by the tail rotor is adjusted by controlling the pitch of the tail rotor, thereby controlling the course. For a single-rotor tailless helicopter, the lateral force is adjusted by controlling the air output at the tail of the fuselage with pedals. For a twin-rotor helicopter, the pedal controls the total pitch difference between the two rotors, that is, one increases and the other decreases, which makes the reaction moments of the two rotors unbalanced and leads to the fuselage deflection.

What is the smallest remote-controlled helicopter in Japan?

C. C.P., a wholly-owned subsidiary of Japan's Bandai Company, began to sell the world's smallest remote-controlled helicopter on June 20 12? Micro falcon? . Since then, it has been transformed, and it was announced on the 2 nd that a smaller remote-controlled helicopter will be released on February 5, 65438.

International Online Special: According to a report by Japan's Sankei Shimbun on September 2, C.C.P, a wholly-owned subsidiary of Japan's Bandai Company, began selling the world's smallest remote-controlled helicopter in June last year? Micro falcon? . Since then, it has been transformed, and it was announced on the 2 nd that a smaller remote-controlled helicopter will be released on February 5, 65438.

It is reported that the fuselage length of the new remote-controlled helicopter is 46 mm, and the total length including the front and rear propellers is 59 mm, which is about 30% smaller than the previous model. This product is controlled by infrared ray, with high-performance gyro sensor and counter-rotating propeller, which can fly smoothly. At present, the company is applying for the world's smallest remote-controlled aircraft record.

In addition, some people say that the smallest helicopter in the world is a single-person subminiature helicopter developed in Japan. The helicopter is equipped with a 37 kW forced cooling engine. The main rotor is about 6 meters in diameter and its own weight is only 1 15 kg.
