旋翼机自制DIY手册(国外英文资料) Lets get to know what youre going to do Why is rotorcraft the safest plane? The rotor of the rotorcraft is not connected with the engine transmission system, and the rotor rotation force of the rotor is obtained by the advance of the aircraft. If the engine stop in the air propeller stopped, the rotor inertia to continue to maintain the machine according to the forward flight, and gradually reduce speed and height, the height decreased at the same time, also have a relative air flow from bottom to top, the rotor can provide lift rotation. In this way, the glider can glide safely down the road with the pilots control. Even if the operator can not control, the rotor machine out of control in the special circumstances, but also like parachute - like landing, although it is rough landing, but there will be no similar scale landing. Of course, the helicopter also has the ability to safely land on the lower side of its rotation. But its spin from the dynamic state of the transition to the rotation of the state, the transition to a certain height loss. If the flight height is not enough, then the helicopter may be too late to transition and touch the ground. The rotorcraft itself is flying in the rotation state, so there is no need to make a transition, so it does not have the high degree of constraint needed for security conversion. 1 now that we have built the car, the question naturally turns to us. When will we build the plane? First, make sure that a private person can build an airplane. Its not as complicated as it seems. Think about it. In 1903, the Wright brothers were in heaven. After 103 years, people now have more flight skills and more flight experience. Why do the Wright brothers make so many two bikes that we cant make them? 2 a lot of people think of DIY aircraft as very complex. It considers it involves aerodynamics, mechanics of materials, aviation meteorology, aircraft dynamics, and so on. Its true, but it does, but its entirely differe
