Design Methodology of a Hybrid Propulsion Driven Electric Powered Miniature Tailsitter Unmanned Aerial Vehicle

Hybrid Propulsion System Design of a VTOL Tailsitter UAV

Tailsitter UAVs with their combined vertical take off and landing (VTOL) and fixed-wing aircraft with full flightspeed regime capability provides a distinct alternative to rotary-wing and ducted fan UAVs (OAVs). ITU-BYU Tailsitter concept aims to obtain the energy efficient regimes across the VTOL and the cruising flight regimes. This paper describes the hybrid propulsion system design approach...

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...

Integrated flight/thrust vectoring control for jet-powered unmanned aerial vehicles with ACHEON propulsion

A Study on Fuel Consumption Reduction Using 48-V Mild Hybrid Technology

Due to the air pollution crisis and increase in greenhouse gases, emission standards are getting tougher gradually. In the other hand reducing the consumption of nonrenewable resources is one of the main goals of the automotive industries in the world. Using electric propulsion along with internal combustion engine is one of the answers. Different designs of Hybrid Electric Vehicles (HEV) have ...

Validated 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 ...
