Abstract

The invention belongs to a method and a device for adjusting the buoyancy force of an airship, and particularly relates to a method and a device for adjusting the buoyancy force of the airship by adopting the thermodynamic cycling of gas. The method and the device for the simple, reliable and lightweight large-area buoyancy force adjustment of a modern high-performance airship such as a high-altitude stratospheric airship, a medium-altitude long-endurance unmanned airship and a low-altitude weight-carrying airship. The gas in a gasbag is used as a heat transfer medium, and is subjected to heat exchange with an external atmospheric environment to realize temperature adjustment. The method and the device have the advantages that the gas carried by the airship is used as a working medium, an open thermodynamic cycling mode is adopted, a system is simple and reliable, and a requirement on air tightness is low; and a refrigeration working mode and a heating working mode can be provided, the thermodynamic cycling efficiency is high, the gas in the gasbag can be cooled and heated to finally meet the requirements of suction, exhaust, temperature control, pressure control and the like during rising, residing in the air and descending.

Description

technical field [0001] The invention relates to modern high-performance airships such as high-altitude stratospheric airships, hollow-air long-endurance unmanned airships, and low-altitude load-bearing airships, in particular to a method and device for adjusting the buoyancy of airships using gas thermal cycles. Background technique [0002] In recent years, driven by the demand for green aviation, heavy-duty transportation, and information platforms, modern high-performance airships using new technologies and materials have flourished and can play an important role in many application fields. Judging from the current development focus, modern high-performance airships mainly include high-altitude stratospheric airships, mid-altitude long-endurance unmanned airships, and low-altitude heavy-duty airships. These airships have the outstanding characteristics of long stay in the air and heavy load, which put forward high requirements on the buoyancy control ability of the airshi...
