Preliminary Design of a Small Unmanned Battery Powered Tailsitter

الملخص EN

This paper presents a preliminary design methodology for small unmanned battery powered tailsitters.

Subsystem models, including takeoff weight, power and energy consumption models, and battery discharge model, were investigated, respectively.

Feasible design space was given by simulation with mission and weight constraints, while the influences of wing loading and battery ratio were analyzed.

Case study was carried out according to the design process, and the results were validated by previous designs.

The design methodology can be used to determine key parameters and make necessary preparations for detailed design and vehicle realization of small battery powered tailsitters.
