How to explain the principle that "the aircraft can still take off from the opposite direction and the same speed conveyor belt"? This title has been discussed repeatedly for several years, but many people have not reviewed the topic, and the topic has changed. But the meaning has not changed. In fact, the amount of information given by this topic is not a lot, and the key points are not given, such as the airspeed at that time. Whether the aircraft turns on the engine, etc. From the opposite direction, the same speed conveyor belt, the same speed can be understood as the speed of the conveyor belt and the speed of the aircraft tires are the same, the aircraft can be maintained at a stable point. In fact, this can indeed take off, but it can neither increase the takeoff distance nor reduce the takeoff distance.
As long as you understand the meaning and don't be confused, it is very simple. First of all, no matter what the power of the aircraft, open the question whether it can take off smoothly and its ground speed, it has nothing to do with the speed of the tire, because the tire only produces friction. Driving before, such as bicycles, cars, etc., as long as it is running on the ground, if the plane is taxiing on the ground, it is no different from the car. The question does not indicate whether the aircraft has started the engine. If it is not turned on, it is impossible to fly.
But if you are driving the engine, you can definitely fly. The conveyor belt is equivalent to the runway. In fact, the problem is around a big circle. The moving belt and the moving tires make everything back to the original point. The plane is still. When the plane is turned on, the plane must be sprinting forward, but the speed of the tire will increase a lot. The distance it takes to take off is still that much, and there is no difference between taking off on a stationary runway.
