This is not necessarily, this should be theoretically said from some basic technologies of the aircraft, rather than whether the two leaves or the three leaves are good but can be said. Propeller efficiency The propeller also has a wing, and it should also be applied to its speed, the double protruding airfoil is obviously not very efficient at low speeds, but it can go up to higher speeds. The smaller the number of blades (integers greater than 0), the higher the efficiency, and the single leaf pulp has the highest efficiency, but it is not suitable for high speeds, trim problems.
Why is there a 2-leaf multi-leaf pulp? The two blades are well trimmed and the production is simple. Easy to install.
Multi-leafed, when the power of the engine increases infinitely, but the speed can not increase infinitely, to output the power of the engine, it is necessary to increase the diameter of the pulp unlimitedly, the most extreme effect is ***, but obviously you can't put the rotor on the fixed-wing aircraft to pull in, huge reverse torsion, structural deformation, landing gear height, etc. (as well as the linear speed of the pulp tip, it will be easy to reach the stall state, efficiency decreases, vibration, twist and break), so we can only increase the number of pulp blades, As mentioned earlier, the propeller is the same as the wing, in fact, it is to rely on the relative speed of the air to produce lift (tension) on the slurry surface, and the air will be discharged in the opposite direction due to the reaction force under the static, and the increase in the number of pulp blades is equivalent to increasing the lift area of the pulp blades, and the power of the engine will be effectively output, which is why we look at the same type of aircraft in World War II from the early to the late stage, there are 2 blades, 3 blades, 4 blades, 5 blades and even 6 blades, which is the result of continuous engine upgrades. In modern times, the development of turbine technology has made the engine have a high speed when it outputs more power, which is why we see that today's small turbo aircraft can output the same power as their engines with 2 blades with a much smaller diameter than World War II aircraft (large turbo aircraft or high-speed aircraft still need more pulp, because the speed of the large diameter slurry tip is too high at high speed and will stall).

The clover is well beaten and more broken.

The blade of the soymilk machine is good with four leaves, because if the power of the soymilk machine is not large enough, and the rotation is not fast enough, the soymilk will not be delicate enough. The design of the four-blade blade is due to the leaves of the blade of the soymilk machine fine grinder, the distance between each blade and each blade is accurately calculated, if it is a six-blade, then the distance between the blades will be shortened, the strength of grinding the beans will be reduced when rotating, and the strength of the front branch will be less soymilk will be rough and will not be delicate.

Is the soymilk machine better with a three-blade blade or a four-blade blade, and the four-blade blade has no blade? Is it better to have a blade or not to have a blade?
Judging from the development process of soybean milk, it should be the 3-leaf serrated knife that is good, and things are improving. The early soymilk machine blades were two-leaf Liang's traces of pure knife oak and slice. Later, it evolved into a three-leaf pure blade, and then became a four-leaf pure blade, a two-leaf serrated blade, a three-leaf serrated blade, a pure blade and a mixed type of serrated blade 2, from a practical point of view, the thickness of soybean milk, the 3-leaf serrated blade is much thinner than the 4-leaf pure blade.
3. From the point of view of the nuclear pulse, the three-leaf serrated blade is more expensive than the four-leaf pure blade.
Function. Choose the right features for your family according to your family's needs, not more features are better. Look at the major. In fact, it depends on whether the soybean milk machine you are about to buy can have professional technology to make soy milk that satisfies you.
