Research on Improving Take-Off Characteristics of Fly Wing with a New Constitution

Article Preview

Abstract:

The take-off control of UAV with fly wing layout is limited by its relatively lower pitch moment. This paper gained the state parameters of a few groups of taking off model by means of numerical simulation. The influence of different models on take-off distance, take-off angle of attack (AOA), take-off safe speed and c.g. location was then analyzed. Based on the analysis, a new fly wing constitution was designed and the corresponding take-off control scheme was suggested as well. Finally, the flight test results shows that this fly wing constitution can gain better take-off control characteristics.
