Flexible netlike solar battery array for stratospheric aerostat

Abstract

The invention provides a flexible netlike solar panel array for a stratospheric aerostat. The solar battery array is based on efficient rigid solar batteries, through a 'fish scale' netlike design method, lightened rigid packaging is carried out on the monolithic efficient rigid batteries, so as to form a monolithic solar battery module; the monolithic solar panel module is installed on a flexible net which is weaved by using flexible fabric and is fitted on the surface of the aerostat; and serial and parallel cables among the rigid batteries and a final main transmission cable are built in each pipeline positioned on the flexible net. According to the scheme, the aim of efficient use of the solar battery array is fulfilled, the flexible net for hanging and installing the rigid solar batteries integrates the functions of an installation substrate, a transmission cable pipeline and a boat body strengthening part; and when application requirements are met, the system composition and total weight are reduced to the maximum degree. In addition, the flexible netlike solar panel array can be designed into a whole type or a sectional combined type according to practical application requirements.

Description

1. Technical field: [0001] The invention provides a development scheme of a flexible mesh solar cell array for a stratospheric aerostat, belonging to the technical field of aerospace vehicle energy systems. 2. Background technology: [0002] As the junction of the existing aviation and aerospace fields, the stratosphere has attracted the attention of many aerospace powers, and has become the focus and hotspot of current technological pioneering research. As a prominent representative of stratospheric aerostats, the stratospheric airship has received great attention from the United States because of its advantages such as high flight altitude, long service life, regional residence, and low environmental pollution. As early as 2003, the NASA Research Center conducted in-depth feasibility studies on high-altitude and long-endurance airships, and determined high-efficiency solar cell arrays, advanced energy storage and management systems, new high-altitude propellers and electri...
