摘要:
A system for controlling yaw associated with an airship may include one or more vertical control surfaces associated with the airship, a first power source and a second power source, each configured to provide a thrust associated with the airship, and a yaw control configured to receive an input indicative of a desired yaw angle. The system may further include a controller communicatively connected to the yaw control, the one or more vertical control surfaces, and the first and second power sources. The controller may be configured to receive an output signal from the yaw control corresponding to the desired yaw angle and to generate a control signal configured to modify a state associated with at least one of the one or more vertical control surfaces, the first power source, and the second power source, such that the airship substantially attains the desired yaw angle.

The present invention relates to a method for controlling land surface temperature using stratospheric airships and a reflector. In the method for controlling land surface temperature using stratospheric airships and a reflector, four corners are connected to a lower end of support lines coupled to be disposed vertically downward from a plurality of airships, and sunlight is reflected by a reflector unfolded into a tetragonal shape in the air, wherein the reflecting surface of the reflector plate is maintained at an angle to remain perpendicular to an incident angle of sunlight to shield, or redirect, the land surface from incident sunlight.

The present invention is a stratospheric-airship-assisted orbital payload launching system that features with high reusability ratio, low cost, short launch-preparation time and robust reliability. The system consists of an airship-based stratospheric launch platform (1), a stratospheric-launched suborbital shuttle (2, SLSS) and an upper stage (3, a modified version of conventional upper stage or a spaceplane). The airship-based stratospheric launch platform (1) employs hydrogen and helium to provide buoyancy in its ascent and high-altitude cruise stages. Given the substantially lower ambient pressure, the usage of hydrogen at high altitude is much safer than on the ground. The SLSS (2) is mounted beneath the platform (1), and an assembly of payload (4) and upper stage (3) is loaded in the cargo bay (2B) of SLSS (2). In a typical orbital payload launching mission, the airship-based stratospheric launch platform (1) ascends to a predetermined altitude in stratosphere, where the air density is much lower than the sea level and wind is relatively slow and steady comparing with the upper troposhere, and then launches the SLSS (2) in a predetermined position and time. After the SLSS (2) is launched, the platform (1) vents hydrogen lifting gas to swiftly unload the extra buoyancy. Subsequently, the platform (1) descends and returns to its ground base. Meanwhile, the SLSS (2) rockets to a predetermined velocity and altitude (above the atmosphere), opens its cargo bay doors (2D) and releases its cargo (i.e., the assembly of upper stage (3) and payload (4)). The upper stage (3) ignites and propels the payload to a predetermined space orbit. At the same time, the SLSS (2) re-enters, and decelerates via aerobraking. It is finally recovered via a conventional wheel landing.

A system for airship hull reinforcement and in-situ repair includes a sensor for detecting a leak in the airship hull of a lighter-than-air airship and a repair mechanism inside lighter-than-air airship for dispensing repair material to seal the leak. A durable airship hull includes an inner gas barrier, an outer gas barrier, and a microlattice layer sandwiched between the inner gas barrier and the outer gas barrier.

The present invention is a variable geometry aircraft that is capable of morphing its shape from a symmetric cross-section buoyant craft to an asymmetric lifting body and even to a symmetric zero lift configuration. The aircraft may include variable span, length, and camber. The variability of the structure and the flexible envelope allows the aircraft to adjust its aspect ratio along with the camber of the upper and/or lower surfaces to achieve varying shapes. This transformation changes both the lift and drag characteristics of the craft and may be accomplished while the craft is airborne.
摘要:
A system for efficiently transporting hydrogen from where it can be economically made to where it is most needed using specially designed airships. Technologies such as geothermal, wind, solar, wave tidal or hydropower can be used to generate electricity in-situ or very near to the primary energy sources. This electricity can then be used to produce hydrogen directly from water through various methods known in the art. Hydrogen can be delivered from the place where it is produced to the place where it is needed using an airship. The hydrogen can provide propulsion energy and serve ancillary needs. In other embodiments of the invention, the airship of the present invention can be used to dramatically reduce the cost of transportation of freight, the cost of passenger transportation, and to save on the area required for landing at the points of loading/unloading and embarkation/debarkation.

In one example, a tethered airship system for high altitude long endurance missions includes a first airship configured to be equilibrially buoyant in a first altitude range and a second airship configured to be equilibrially buoyant in a second altitude range, such that the first airship is at least five kilometers above the second airship. The first airship and second airship are connected by a tether.

A hydrogen airship for efficiently transporting hydrogen from where it can be economically made to where it is most needed using specially designed airships. Hydrogen can be delivered from the place where it is produced to the place where it is needed using an airship in which the hydrogen gas can also be used for generating lift, providing propulsion energy and serving ancillary needs. A unique docking system can use a remotely piloted unmanned aircraft flown from the mother craft to carry a guide line into a receiving attachment point.
摘要:
An air vehicle such as an airship is provided, having a rounded top portion, and the bottom portion of which has a substantially planar shape, including a region having a smaller inclination, which is referred to as a bottom surface, and the surface area of which is larger than that of an intermediate region having a greater inclination, referred to as an intermediate surface. The general shape produces, due to relative wind, a resulting overall downward force near the ground. The vehicle also includes a device for anchoring same to the ground, the anchoring device being stationary or controllable from the vehicle, located at the front portion of the vehicle, and projecting downward, in particular a ram including a portion which can be expanded by applying a bar against a translatably movable shoulder. Also included is a landing method implementing such a vehicle.
