Study on radiation power density effects on flight performance

Abstract

KEYWORD: Laser, UAV, Radiation, Power density, Maximum level flying speed ABSTRACT: Laser-motive UAV (unmanned aerial vehicles) is a new concept UAV. Based on analysis of conservation equation of photoelectric conversion irradiated by laser energy, UAV load's demand for power density and heat convection balance, a model is established to analyze the relationship between UAV maximum level flying speed, maximum wing loading and laser irradiation power density, propulsion system output power, photovoltaic cells operating temperature, and further a method is proposed to calculate and analyze UAV flying height, maximum level flying speed and maximum wing loading, etc. The calculation and analysis method proposed in this thesis provides basis for the design and analysis of Laser-motive UAV.
