The invention relates to an air-transportable device (100) for projecting pressurized liquid over a surface, comprising a rotating washing head and an inspection system (11) with LED bulbs and cameras. The air-transportable device (100) is secured to an aircraft (200, 500) by the upper surface thereof or by means of straps and can be configured for different uses such as cleaning wind and photovoltaic facilities, extinguishing fires or cleaning insulators.

A transportation system and method serve passenger-conveying VTOL air vehicles (AVs) at a vertiport. The vertiport has a flight deck including at least one landing pad, a passenger terminal, and a dynamic partition arrangement that defines a capsule for receiving one of the AVs at a time. The dynamic partition arrangement assumes a first open state in which it is open to the flight deck and closed to the passenger terminal and a second open state in which it is closed to the flight deck and open to the passenger terminal. A robotic system includes a handling robot that automatically approaches and docks with the AV after landing, and conveys the AV between the landing pad and the capsule via an opening provided by the first open state of the dynamic partition.

In various embodiments, specialized vehicle launch systems and methods are provided to enable personnel to launch and operate one or more UAVs from the safety of a vehicle or other mobile location. In various embodiments, a launch system comprises a launch device and an operator terminal. The launch device is adapted to be mounted on an exterior surface of a vehicle and is communicably coupled to the operator terminal, which is operable from the interior of the vehicle. The vehicle launch system allows an operator to control one or more UAVs from inside the vehicle, without requiring the operator to step outside of the vehicle to interact with the UAV or launch device.

A helicopter includes a propulsion system, gimbal assembly, and a controller. The propulsion system includes a first and second rotor assembly, wherein the first rotor assembly comprises a first motor coupled to a first rotor, the first rotor comprising a plurality of first fixed-pitch blades and the second rotor assembly comprises a second motor coupled to a second rotor, the second rotor comprising a plurality of second fixed-pitch blades. The second rotor is coaxial to the first rotor and is configured to be counter-rotating to the first rotor. The controller is communicably coupled to the gimbal assembly and is configured to provide instructions to at least one of the first or second gimbal motors in order to orient the plurality of first and second fixed-pitch blades into a position that permits wind to rotate the first and second fixed-pitch blades and thereby charge the power source.

An unmanned aircraft system has a vertical takeoff and landing flight mode and a forward flight mode. The unmanned aircraft system includes an airframe, a rotor assembly rotatably coupled to the airframe and a propeller rotatably coupled to the airframe. The rotor assembly including at least two rotor blades having tip jets that are operably associated with a compressed gas power system. The propeller is operably associated with an electric power system. In the vertical takeoff and landing flight mode, compressed gas from the compressed gas power system is discharged through the tip jets to rotate the rotor assembly and generate vertical lift. In the forward flight mode, the electric power system drives the propeller to generate forward thrust and autorotation of the rotor assembly generates vertical lift.

Aspects may provide navigation assistance to guide a robotic vehicle through a course defined by a plurality of gates each including a fiducial marker that encodes a location, an ordering, and a pose of the corresponding gate. In some implementations, an optimal trajectory may be generated through the course and used to determine whether to provide navigation assistance to the robotic vehicle. The optimal trajectory may include a reference path that extends through openings formed in center portions of the gates, and may be used to create a virtual tunnel indicating a maximum distance that the robotic vehicle may deviate from various points along the reference path. If the robotic vehicle deviates from the optimal trajectory by more than the distance while traversing the course, navigation assistance may be provided to the robotic vehicle.

A system includes a signal monitor to monitor a time rate of change of a revolution per minute (RPM) trim signal that is received from an RPM command path to control a velocity of a helicopter rotor. An icing detector detects for the presence of ice accumulation on the helicopter rotor by comparing the time rate of change of the RPM trim signal to a predetermined threshold for the time rate of change.
