초록 ▼

A lighter than air apparatus is provided with a gas impermeable sheeting material having a pathway either extending through the apparatus itself or adjacent to the apparatus. One or more control surfaces are provided proximately to an aperture in the pathway for deflecting air passing through the pathway. A propulsion unit with the pathway propels air through pathway. The pathway, the control surfaces, and the control unit allow the lighter than air apparatus to control its bearing and efficiently maintain its position over the Earth.

대표청구항 ▼

A substantially spherical lighter than air apparatus having a quantity of lighter than air gas disposed therein providing the lighter than air apparatus with a desired buoyancy and capable of maintaining its bearing and position relative to the Earth, comprising: a flexible sheeting material having an outer surface of a substantially spherical shape when filled with a quantity of lighter than air gas, the sheeting material having first and second apertures in the outer surface; a pathway coupled within the sheeting material, such that the pathway is coupled between the first and second apertures, the pathway permitting air to flow through the first and second apertures; at least one control surface coupled proximately to one of the first and second apertures and the pathway, the control surface deflecting air passing through the pathway, such that the control surface controls the bearing of the lighter than air apparatus; a propulsion unit coupled within the pathway, the propulsion unit propelling air through the pathway to the control surface, such that the propulsion unit controls the position of the lighter than air apparatus relative to the Earth; an air ballast pump coupled to the lighter than air apparatus; at least one second ballonet disposed within the sheeting material and coupled to the air ballast pump via a first valve, such that gas having a density at least that of air is pumped into the second ballonet by the air ballast pump via the first valve; a second valve coupled to the ballonet, the second valve purging the gas in the second ballonet outside of the lighter than air apparatus; a station keeping system coupled to the control surface, the station keeping system monitoring a position and altitude of the lighter than air apparatus relative to the Earth and controlling the control surface to maintain the position; at least one Global Positioning System device coupled to a power source, such that a position of the lighter than air apparatus can be determined; at least one ballast tank coupled within the sheeting material; a pump; and line coupled between the pump and the ballast tank, such that the pump moves liquid to and from the ballast tank to change a center of gravity of the lighter than air apparatus; wherein the station keeping system comprises: a compass indicating a bearing of the lighter than air apparatus; an altimeter providing a measurement of an altitude of the lighter than air apparatus; an external anemometer coupled to an exterior of the lighter than air apparatus measuring wind velocity impinging upon the lighter than air apparatus; an internal anemometer coupled within the pathway measuring velocity impinging upon the pathway of the lighter than air apparatus; a wind vane measuring wind direction impinging upon the lighter than air apparatus; and a computer coupled to the control surface, propulsion unit, Global Positioning System device, pump, compass, altimeter, internal and external anemometers, and the second ballonet, the computer outputting signals to control the propulsion unit, the inflation and deflation of the ballonet, deflection of the control surface, and pumping of ballast from and to the ballast tank based upon readings from the compass and comparisons of actual values of the wind velocity, wind direction, altitude and position from the internal and external anemometers, wind vane, altimeter, and Global Position System device and preselected values of the wind velocity, wind direction, altitude, and position to maintain the lighter than air apparatus at a desired position and altitude.
