Abstract
A variable density airship lift chamber system for airships provides more efficient lift control. The airship lift chamber system includes at least one lift chamber filled with lift gas and configured to provide lifting force, a heat exchanger configured to heat the lift gas in the at least one lift chamber, a compressor unit configured to withdraw the lift gas from the lift chamber and to compress the withdrawn lift gas, a pressure tank configured to store the withdrawn compressed lift gas from the compressor unit, a refrigeration orifice formed in the lift chamber, and a valve that connects the pressure tank to lift chamber through the refrigeration orifice. The airship lift chamber system controls density of the lift gas in the lift chamber by heating the gas while removing the gas from the lift chamber and by supplying gas into the lift chamber.
