What are the five aeronautical blades of Midea fans?

Midea Fan Company and Northwest Polytechnic University jointly conducted research and cooperation to improve, transform and secondarily develop the advanced design technology of aircraft wings, airfoils, propellers and engines, and applied them to fan blade technology, designing and developing a series of high-quality products. - Efficient and low noise aircraft aerodynamic blades. In accordance with the aerodynamics, the air outlet is smoother. Six major advantages: ① Larger air volume. Based on the design principle of aviation wings, the air volume is larger. For example, the air volume of the 16-inch fan reaches 68.6 m3/min, which is 27% higher than the national standard value; ② Lower noise: the sound value reaches 56.4 dB (A), which is 15.8% lower than the national standard value; ③ More energy saving: the level of energy efficiency offans using new wing blades all reached level 1

; ④ More environmentally friendly: The fan blades are made of imported raw materials. It is more environmentally friendly ⑤ The wind is smoother: the aviation five-blade curve follows the principle of aerodynamics, imitating the shape of the wing and blowing; the wind is gentler; ⑥ The appearance is more beautiful: The new five-blade aviation wind blade is more beautiful than the ordinary five-blade blade.

The object on a helicopter is called a rotor. Its structure is different from that of an electric fan, but is similar to the structure of an airplane wing. The upper part of the cross section is an arc and. the lower part is a straight line. The principle of generating lift is also similar to that of a fixed-wing aircraft, when this structure works, the airflow from top to bottom will generate adoes not have a difference in pressure upwards, allowing the aircraft to obtain lift. , the fixed-wing aircraft moves forward to circulate the airflow up and down along the wing surface, while the helicopter achieves this through the rotation of the rotor. If you use a structure like an electric fan, you can also fly the helicopter. However, the advantages and disadvantages of this structure are that if the engine stops in the air, the helicopter will fall. cause the rotor to reverse. It is almost impossible to restart the engine. When the wing structure falls, it will not reverse due to resistance. At the same time, due to inertial rotation, it can continue to provide part of the lift. , which gives precious time for the engine to restart.
