Abstract

The invention discloses an energy supply system for a stratosphere electricity-electricity hybrid solar airship. The system is an electricity-electricity hybrid energy supply system which takes a solar battery array as a main power supply, takes a regenerative hydrogen-oxygen fuel cell and a high-energy power storage battery pack as auxiliary power supplies, takes a direct-current brushless motor and a motor driving controller as drive devices, takes an airship-loaded energy monitor as an energy distribution system, and takes a one-way DC / CD converter and a two-way DC / CD converter as voltage regulating devices. The solar battery array is connected with the one-way DC / CD converter with maximum power point tracking through a cable; the one-way DC / CD converter is connected with the driving controller of the direct current brushless motor through the cable; the controller controls the direct current brushless motor to drive a high altitude propeller thruster; the one-way DC / CD converter is connected with the two-way high-voltage DC / CD converter through the cable; and the one-way DC / DC converter is connected with a charging regulator of the high-energy power storage battery pack. The energy supply system realizes reasonable distribution of power, and ensures the maneuvering safety and long service life of the stratosphere electricity-electricity hybrid solar airship.

Description

1. Technical field: [0001] The invention relates to an energy supply system for a stratospheric electric-electric hybrid solar airship, belonging to the technical field of aerospace vehicle energy systems. 2. Background technology: [0002] The airship uses the hull to be filled with a gas that is less than the specific gravity of air, such as helium or hydrogen, and is lifted into the air by buoyancy, with less energy consumption. According to the flight altitude, it can be divided into tropospheric and stratospheric airships. Stratospheric airships generally fly or hover at an altitude of about 25,000 meters. The temperature in this flight area does not change with altitude, there is almost no water vapor condensation, there is no weather such as thunder and electricity, and there is no atmospheric convection. Therefore, people use stratospheric airships as long-term airborne platforms for communication, earth observation, land and resources monitoring and early warning. ...
