Investigation on approach to control lift distribution of wing by distributed propellers

In this paper, the lift distribution of the wing after distributed propeller is studied. Using a high efficient hybrid fast calculation method (BVP), we can calculate a lot of different states to analyze the influence of distributed propeller on the wing lift distribution. It can be seen that there are many factors which can affect the wing load distribution. In this paper, it is found that the position of the propeller, the rotation speed and the rotation direction have great influence on the lift distribution, while the chord direction and the vertical position have little influence on the shape of the spread lift distribution. The calculation results also show that when the propeller number increases, the total power demand is reduced. However, this paper does not match the propeller and the wing properly, so it can not show the further potential of the distributed propeller.
