Long-flight-time stratosphere aerostat system and power generation method thereof

Abstract

The invention provides a long-flight-time stratosphere aerostat system and a power generation method thereof. The system comprises an aerostat capsule, a pod, a power generation subsystem and a powergeneration cable, the pod is hung at the bottom of the aerostat capsule, the power generation subsystem is hung at the bottom of the pod, the power generation cable is composed of a force bearing material and a cable and used for connecting the power generation subsystem with the pod, a height adjusting system is arranged on the pod and used for adjusting height of the power generation subsystem and comprises a height decision-making device, a winding motor and a cable storage barrel connected on the output end of the winding motor, and one end of the power generation cable is wound on the cable storage barrel for a plurality of circles and then connected with an energy source subsystem in the pod while the other end of the same is connected with the power generation subsystem. By hangingthe power generation subsystem at the bottom of the pod and adjusting the height of the same through the height adjusting subsystem, the power generation subsystem is enabled to generate power at a height where wind energy is probably more, so that energy utilization rate of a wind field is increased. The system is applied to aerostats and energy supply systems thereof.

Description

technical field [0001] The invention relates to an aerostat and an energy supply system thereof, in particular to a long-endurance stratospheric aerostat system and a power generation method thereof. Background technique [0002] The stratospheric aerostat operates at an altitude of about 20km and relies on the static buoyancy of the air to stay in the air. The long-endurance stratospheric aerostat has unique advantages in environmental monitoring, safety monitoring, high-resolution real-time regional monitoring, disaster prevention and mitigation, early warning and defense, and regional communications. [0003] The energy subsystem of the long-endurance stratospheric aerostat provides energy for the load, power, control and other subsystems, and is a key subsystem that restricts the flight performance and mission performance of the stratospheric aerostat. The main requirements of the long-endurance stratospheric aerostat for the energy subsystem include: high power and lon...
