Lifting-wing Multicopter
Lifting-wing multicopter is a combination of lifting wing and multirotor. The plane of the rotor disc and lifting wing are installed at a fixed angle (for example, about 30-45 degrees), which greatly improves the forward flight efficiency while retaining the simple and reliable structure of multicopter and wind resistance. The unique layout is significantly different from the existing conventional vertical takeoff and landing aircraft such as tail-sitter aircraft and convertiplane.
At present, almost all aircraft are in multicopter mode or fixed-wing mode most of the time, while the lifting-wing multicopter is always in the mixed phase of multicopter mode and fixed-wing mode. Compared with traditional fixed-wing and convertiplane, the short wing and strong rotor of the lifting-wing multicopter make it have strong wind resistance.[1]
History
In 2015, the University of Leuven, Belgium, proposed a hybrid configuration aircraft with a lifting-wing structure, named VertiKUL2, whose wing and the rotor are installed at 45 degrees to improve wind resistance.[2]
The reliable flight control group of Beihang University https://rfly.buaa.edu.cn/ formally proposed the lifting-wing multicopter configuration in 2018[3], and began the design and basic performance verification of the prototype of the lifting-wing multicopter. Compared with the traditional multicopter, it was concluded that the power consumption of the lifting-wing multicopter could be reduced by about 50% within a certain cruise speed range through experiments.
In 2019, the reliable flight control group of Beihang University began the design of the lifting-wing multicopter[4], proposed evaluation methods for range and transition time performance, and established a comprehensive model for it. Based on this, flight experiments were carried out and the expected results were achieved[5].
In 2019, VOLITATION designed a multicopter with lifting wing, named VesperTilio [6].
