Abstract:
An airship is provided. The airship includes a hull configured to contain a gas, at least one propulsion assembly coupled to the hull and including a propulsion device, and at least one aerodynamic component including a plurality of fairing structures including one or more slats, wherein the at least one aerodynamic component is associated with the hull and is configured to direct airflow around the airship.
Abstract:
Modern farming is currently being done by powerful ground equipment or aircraft that weigh several tons and treat uniformly tens of hectares per hour. Automated farming can use small, agile, lightweight, energy-efficient automated robotic equipment that flies to do the same job, even able to farm on a plant-by-plant basis, allowing for new ways of farming. A hybrid airship-drone has both passive lift provided by a gas balloon and active lift provided by propellers. A hybrid airship-drone may be cheaper, more stable in flight, and require less maintenance than other aerial vehicles such as quadrocopters. However, hybrid airship-drones may also be larger in size and have more inertia that needs to be overcome for starting, stopping and turning.

Abstract:
The invention relates to a multipurpose airship and, more particularly, to a hybrid dirigible. The airship comprises a body (2) having a parallelepiped shape and docking means (8) comprising four rods connected by a frame and designed to be extractable from the body (2), the ends of these rods being provided each with at least one vacuum cup for adhering to a substantially vertical surface of a building. The docking means (8) are provided with grips adapted to engage with the docking means (8) of another airship of the same design. The invention also relates to a set of airships including at least two said airships. The proposed airship does not require a lot of space for its takeoff and provides fast and secure evacuation of people from tower buildings. In addition, the invention provides the possibility of varying the airship payload directly in flight depending of specific needs.
Abstract:
A system comprising an unmanned aerial vehicle (UAV) having wing elements and tail elements configured to roll to angularly orient the UAV by rolling so as to align a longitudinal plane of the UAV, in its late terminal phase, with a target. A method of UAV body re-orientation comprising: (a) determining by a processor a boresight angle error correction value bases on distance between a target point and a boresight point of a body-fixed frame; and (b) effecting a UAV maneuver comprising an angular role rate component translating the target point to a re-oriented target point in the body-fixed frame, to maintain the offset angle via the offset angle correction value.
Abstract:
A hybrid VTOL vehicle having an envelope configured to provide hydrostatic buoyancy, a fuselage attached to the envelope and having at least one pair of wings extending from opposing sides thereof to produce dynamic lift through movement, and a thrust generation device on each wing and configured to rotate with each wing about an axis that is lateral to a longitudinal axis of the envelope to provide vertical takeoff or landing capabilities. Ideally, the envelope provides negative hydrostatic lift to enhance low-speed and on-the-ground stability.
Abstract:
A payload delivery and recovery system, having a payload including a data collection device arranged to collect data, and a controllable ascent vehicle comprising a controllable lighter than air (LTA) mechanism detachably coupled to the payload and used during an ascent phase to deliver the payload to a pre-determined altitude. The payload delivery and recovery system also having a controllable descent mechanism releasably attached to the controllable ascent vehicle and that can be used during a descent phase for reducing a rate of descent of the payload subsequent to release of the payload at the pre-determined altitude and including a control system for navigating the payload to a desired ground location during a recovery phase.
Abstract:
The present invention is a variable geometry lighter-than-air (LTA) aircraft that is adapted to morph its shape from a symmetric cross-section buoyant craft to an asymmetric lifting body and even to a symmetric zero lift configuration. The basic structure is a semi rigid airship with movable longerons. Movement of the longerons adjusts the camber of the upper and/or lower surfaces to achieve varying shapes of the lifting-body. This transformation changes both the lift and drag characteristics of the craft to alter the flight characteristics. The transformation may be accomplished while the craft is airborne and does not require any ground support equipment.

Abstract:
Lighter than air apparatuses include at least one ballast container having an electrically insulated and fire resistant, an envelop containing a gas and a plasma generating and heating assembly, where the containers provide lift by generating a plasma within the envelop. In certain embodiments, the envelop includes an expandable portion.
