Abstract: A tethered unmanned aerial spraying system comprising a tether line, a power source, a plurality of supporting beams and a plurality of pairs of motorized propellers, wherein each pair of motorized propellers is supported by the ends of a corresponding supporting beam, and a control unit configuredto control each motorized propeller. The tether line includes a flexible hose for delivering spraying agent and a power line, supplying electricity to the motorized propellers from the power source. At least a portion of the tether line is covered by a rigid frame and is carried thereby, wherein the supporting beams are attached to the rigid frame so as to be arranged longitudinally to one another, and the neighboring supporting beams of pairs of motorized propellers have unequal length. The system provides compact configuration of an easily deployable system having increased stability and improved lifting capabilities or energy-effectiveness.

Abstract: Methods and systems for unmanned aerial vehicles are provided. One method includes receiving, by a control system, sensor data from a mobile ground-based platform and sensor data from a ground-based radar surveillance system, the control system configured to communicate with a first UAV and a second UAV; detecting, by the control system, an object likely to impede the second UAV flight within a flight path, the object detected based on the sensor data received from the mobile ground-based platform, the ground-based radar surveillance system or both the ground-based radar surveillance system and the mobile ground-based platform; generating, by the control system, an indicator indicating an object in the flight path; and transmitting, by the control system, the indicator to the first UAV.

Abstract: A fixed wing drone comprises an air channel embedded therein. The air channel has an upstream an air inlet. A microcontroller mounted within the drone is configured to control navigation of the drone. An air scoop having a section positioned adjacent the inlet to the air channel is adjustable between a first position to capture and divert air into the inlet and thereby to air channel and a second position to block air flow into the air inlet. The air scoop is positioned to divert air flow into the air channel and to the gas sensor during forward flight of the drone. In one embodiment, the fixed wing drone comprises an aircraft having a fuselage and at least two wings. In another embodiment, the fixed wing drone has a flying wing construction, that is, is a tailless design.

Abstract: Towed aerodynamic platforms approach the behavior of flat plate airfoils to achieve high lift -to-drag (L:D) performance when operated at low pitch angles. A lead aircraft may tow multiple platforms to form train units. Low form drag and high L:D enable solar aircraft that are more robust and faster than approaches extending wingspan rather than extending the length of the aerial train. Applications extend beyond solar aircraft and include vehicles towed along an overhead monorail system and aerial drones.

Abstract: An airship comprising an envelope having a shape, a volume, and a frontal area. A lifting gas within the envelope. A propulsion system. A volume change mechanism arranged to change the shape of the envelope, wherein the change in shape of the envelope changes the volume of the envelope, the change in volume of the envelope causes a change in the buoyancy of the airship, and the change in shape of the envelope causes the frontal area of the envelope to change proportionally to the change in volume of the envelope.
