Electric Multirotor Propulsion System Sizing for Performance Prediction and Design Optimization
One of the more daunting tasks of designing a multirotor unmanned aerial vehicle (UAV) is the selection of a propulsion system that will provide desired performance. Rigorous methods for selecting these drive components, that is, the motors, propellers, and batteries for electric UAVs are not readily available. Currently, many UAV designs are based on legacy selections or limited and at times i...
متن کاملValidated Modeling and Synthesis of Medium-scale Polymer Electrolyte Membrane Fuel Cell Aircraft
This paper describes a methodology for design and optimization of a polymer electrolyte membrane (PEM) fuel cell unmanned aerial vehicle (UAV). The focus of this paper is the optimization of the fuel cell propulsion system and hydrogen storage system for a baseline aircraft. Physics-based models, and experimentally-derived sub-system performance data are used to characterize the performance of ...
متن کاملRobust Sensor Fusion for State Estimation on Agile Electric UAVs
There has been a rapid increase in the use of unmanned aerial vehicles (UAVs). On UAVs, autopilots are fundamental components that use a variety of sensors to estimate vehicle’s state and perform actuation, ultimately allowing to perform the assigned tasks. Modern UAVs are often being powered by electric motors which provide a number of advantages over internal combustion engines, in terms of w...
متن کاملDesign Methodology of a Hybrid Propulsion Driven Electric Powered Miniature Tailsitter Unmanned Aerial Vehicle
Contrary to the manned tailsitter aircraft concepts, which have been shelved and forgotten after mid 1960’s, the unmanned versions of these concepts have become popular. Since, tailsitter type UAVs combine both vertical takeoff and landing (VTOL) operation and relatively high speed cruise flight capabilities which provide manifest advantages over the other VTOL aircraft concepts, including heli...
متن کاملDesign Considerations for Long Endurance Unmanned Aerial Vehicles
The arena of Unmanned Aerial Vehicles (UAVs) has for many years been dominated by the defence industries. The reason for this can be attributed to the complexity and cost of designing, constructing and operating of these vehicles. An additional contributing factor is the legislative issues around operating an unmanned aircraft in civilian airspace. However in resent years advances in micro-elec...
