[0004] Hydrogen fuel cell drones have gradually attracted people's attention, and a consensus has been reached on the fuel cell hybrid power supply scheme. However, few people have been involved in the weight ratio of hydrogen and auxiliary power for the fuel cell hybrid power supply used in drones.
Chinese patent 202010020776.5 proposes a hydrogen fuel cell for drones, but does not specify how to apply hydrogen fuel cells to drones. Chinese patent 201911085243.9 proposes a hydrogen fuel cell drone system, but does not point out how to The weight of hydrogen gas and the weight of auxiliary power supply are matched

Abstract

A method for configuring a fuel cell hybrid power system for an unmanned aerial vehicle provided by the present invention is specifically as follows: first select an unmanned aerial vehicle flight platform to obtain the maximum weight configuration of the power supply system; conduct a flight test to obtain the flight power and steady-state flight of the take-off process The average power demand of the process, and then obtain the steady-state output power level and the weight of the fuel cell; when the weight of the fuel cell is less than the maximum weight configuration, calculate the sum of the hydrogen weight and the weight of the auxiliary power supply; carry out the fuel cell loading test to obtain the shortest fuel cell weight Loading time and output power; calculate the minimum energy density requirement of the auxiliary power supply, select the auxiliary power supply when the minimum energy density requirement is less than the maximum energy density, obtain the weight ratio of the auxiliary power supply, and obtain the hydrogen weight ratio after judging by the weight constraint, and obtain the auxiliary power supply The ratio of weight and hydrogen weight is the longest endurance configuration of the UAV flight platform under the maximum take-off weight.

Description

A configuration method of a fuel cell hybrid power system for unmanned aerial vehicles technical field The invention belongs to the field of fuel cells, be specifically related to a kind of unmanned aerial vehicle fuel cell hybrid power system configuration method Law. Background technique With the development of the unmanned aerial vehicle industry, unmanned aerial vehicles have been widely used due to their advantages of small size, easy operation and low cost. Used in military and civilian fields. UAVs are generally powered by lithium batteries, which have the obvious disadvantage of short battery life, which greatly limits the The development of drones. In order to improve the cruising range of the UAV, a fuel cell hybrid power system composed of hydrogen energy and auxiliary power is used. The system can supply energy for UAVs, subvert the application scenarios and use strategies of UAVs, and has extremely high potential application value. Since the internal...
