Embodiment Construction

[0067] Specific embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0068] The overall parameters of the solar UAV include UAV weight characteristic parameters, geometric shape parameters, aerodynamic characteristic parameters, and power characteristic parameters matched to the core components of the whole system. The design of these overall parameters is determined by the characteristics of the solar drone itself: its energy comes from solar radiation, flight date, flight altitude, and geographical location will all affect flight performance; its flight process involves energy collection, consumption and storage, and energy It is closely related to the level of technology and the way of energy supply. In the design process, it is necessary to sort out the coupling relationship between the various systems and establish a mathematical model that is as simple as possible without distortion. The present ...

Abstract

The invention discloses a general parameter determination method and system for a solar unmanned aerial vehicle. The solar unmanned aerial vehicle adopts solar radiation as the unique energy source, and during a flight of the unmanned aerial vehicle, energy collection, energy consumption and energy storage are involved; moreover, since an unmanned aerial vehicle body, energy power and flight management are coupled with one another, a conventional design method and process for airplanes cannot be directly applied. According to the method, on the basis of a weight balance relation, a power balance relation and an energy balance relation of a point with the weakest solar energy in a flight profile, iterative computation is conducted on weight characteristics, aerodynamic characteristics and other main parameters, and general parameters of a primary scheme meeting tactical and technical index requirements can be obtained, wherein the general parameters mainly include the total weight of the unmanned aerial vehicle, the weight of a subsystem, a reference appearance, a lift-drag ratio, a solar cell laying rate, power characteristics matched with each kernel component of the whole systemand the like. The general parameter determination method for the solar unmanned aerial vehicle can be applied to primary general scheme design of this type of unmanned aerial vehicle.

Description

technical field [0001] The invention relates to a method and system for determining overall parameters of a solar unmanned aerial vehicle, which are used for the preliminary overall scheme design of this type of unmanned aerial vehicle, and belong to the technical field of overall design of unmanned aerial vehicles. Background technique [0002] Solar UAV is an electric aircraft powered by solar radiation, and it is the product of the combination of aviation science and technology and new energy technology. During the day, the solar-powered UAV relies on the solar cells laid on the surface of the body to convert the absorbed solar radiation energy into electrical energy, which is used to maintain the normal operation of the power system, avionics and payloads, and to charge the secondary battery; at night, The solar drone releases the electrical energy stored in the secondary battery to maintain the normal operation of the entire system. Solar-powered drones have long cruis...
