A gas density control system for airships is provide. The system embodies a hybrid ballonet and low pressure gas storage tank combination for regulating the density and volume of the airship lift gas, wherein the ballonet is fluidly connected to the storage tank by a transfer hose. The base of the ballonet is also sealed along an exterior surface of the length curvilinear geometric shaped storage tank so that as the storage tank selectively rotates the ballonet either wraps or unwraps around the length, whereby the lift gas transfer to and from the storage tank to the ballonet, respectively. A transfer hose reel is provided to rotate with the storage tank so that as the ballonet wraps about the storage tank the transfer hose winds about the transfer hose reel, and vice versa. Thereby the system precisely adjusts the ballonet's volume, which in turn controls its lifting force.

A control system for an atmospheric balloon system includes a navigation parameter system having a meteorological characteristic input, a balloon kinematic monitor, an objective input and a parameter range generator configured to generate an altitude search range for the atmospheric balloon system based on air stream vectors, balloon kinematics, and a target balloon position. An onboard balloon control system is in communication with the navigation parameter system and includes a comparator to determine a course difference of a measured course relative to a course range. An altitude selection module selects a target altitude within the altitude search range having an air stream vector that decreases the course difference. A propulsion selection module is configured to select a propulsion value that decreases the course difference.

Aspects of the disclosure relate to an aerial vehicle. The aerial vehicle may include an envelope having a plurality of tendons and formed from a first plurality of gores. The aerial vehicle may also include one or more ballonets arranged within the envelope. An outer membrane may be arranged around at least part of the envelope and formed from a second plurality of gores. The outer membrane may include at least one panel attached at one side to the outer membrane between a pair of the second plurality of gores and attached at an opposite side to the envelope. The outer membrane may be arranged to improve aerodynamics of the envelope when the aerial vehicle is in flight.

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.

An earth to space transport method, system and apparatus. The earth to space transport system can include a main body; a plurality of storage tanks disposed in an inside of the main body, the storage tanks configured to store helium; one or more electric jet propulsion turbines coupled to the main body; a first inflatable cushion disposed at a top of the main body and a second inflatable cushion disposed at a bottom of the main body; a space capsule disposed above the first inflatable cushion; a power generator; and a rotor propeller. Such an earth to space transport system may be utilized to efficiently move humans, satellites and cargo from earth to space.

An airship includes a ballonet, a ballonet tracking system, and a vehicle management system. The ballonet is disposed within the airship and includes a ballonet surface. The ballonet tracking system includes one or more light emitters disposed within the ballonet at one or more fixed locations and one or more light detectors disposed within the ballonet at the one or more fixed locations. The ballonet tracking system measures a plurality of distances between one or more fixed locations and one or more locations on the ballonet surface. The ballonet tracking system also calculates differences between a predetermined set of expected distances and the plurality of measured distances. Based on the calculated differences, the ballonet tracking system calculates a volume of the ballonet. The vehicle management system is communicatively coupled to the ballonet tracking system and controls the operation of the airship using the calculated volume of the ballonet.
