Abstract
An altitude movement device comprising of a ballonet within an outer envelope with the ballonet configured to control buoyancy and an apparent wind generating device combined with the altitude movement device to generate an apparent wind to propel the vehicle laterally with respect to the direction of the jet stream.
Claims17
A lighter-than-air vehicle (“LAV”) for navigating a jet stream, the vehicle comprising:
- an altitude movement device comprising of a ballonet within an outer envelope expanding to a spherical shape with a neck near the bottom of the outer envelope and with the ballonet configured to control buoyancy;
- a tether attached to the neck of the outer envelope;
- an apparent wind generating device combined with the altitude movement device, wherein the apparent wind generating device is configured to generate an apparent wind;
- and
- a lateral movement device combined with the apparent wind generating device, wherein the lateral movement device is configured to move the LAV laterally with respect to the jet stream, wherein the tether attaches the apparent wind generating device and the lateral movement device to the altitude movement device.
A lighter-than-air vehicle (“LAV”) for navigating a jet stream, the vehicle comprising:
- an altitude movement device comprising of a ballonet within an outer envelope with the ballonet configured to control buoyancy;
- an apparent wind generating device combined with the altitude movement device, wherein the apparent wind generating device is configured to generate an apparent wind, wherein the apparent wind generating device comprises of a motorized propeller oriented to propel the LAV in the direction of the jet stream to generate apparent wind from movement in the jet stream;
- and
- a lateral movement device combined with the apparent wind generating device, wherein the lateral movement device is configured to move the LAV laterally with respect to the jet stream, wherein the lateral movement device comprises of a rotational motor connected to the outer envelope to spin the outer envelope in either a clockwise or counter-clockwise direction to move the LAV laterally with respect to the direction of the jet stream, wherein the motorized propeller is oriented in the direction of the jet stream to generate apparent wind while the rotational motor spins the outer envelope.
A lighter-than-air vehicle (“LAV”) for navigating a jet stream, the vehicle comprising:
- an altitude movement device comprising of a ballonet within an outer envelope with the ballonet configured to control buoyancy;
- an apparent wind generating device combined with the altitude movement device, wherein the apparent wind generating device is configured to generate an apparent wind;
- and
- a lateral movement device combined with the apparent wind generating device, wherein the lateral movement device is configured to move the LAV laterally with respect to the jet stream, wherein the apparent wind generating device is a drag balloon that extends at a higher altitude than the outer envelope.
A lighter-than-air vehicle (“LAV”) for navigating a jet stream, the vehicle comprising:
- an altitude movement device comprising of a ballonet within an outer envelope with the ballonet configured to control buoyancy;
- an apparent wind generating device combined with the altitude movement device, wherein the apparent wind generating device is configured to generate an apparent wind from movement of the LAV in the direction of the jet stream;
- and
- a lateral movement device combined with the apparent wind generating device, wherein the lateral movement device comprises of a rotational motor connected to the outer envelope to spin the outer envelope in either a clockwise or counter-clockwise direction to move the LAV laterally with respect to the direction of the jet stream.
A lighter-than-air vehicle (“LAV”) for navigating a jet stream, the vehicle comprising:
- an altitude movement device comprising of a ballonet within an outer envelope with the ballonet configured to control buoyancy;
- a means for generating apparent wind from forward or reverse movement in the direction of the jet stream;
- and
- a means for lateral movement with respect to the direction of the jet stream.
