The present technology is directed to a remotely controlled aircraft that can be transported without the risk of damaging certain components, such as the arms and / or propellers. In one non-limiting example, the remotely controlled aircraft technology described herein provides a housing that allows the arms of the remotely controlled aircraft to extend and / or retract through openings in the housing. When retracted, the arms and propellers are protected within an area of the structure of the housing, and when extended, the arms and propellers are operable to make the remotely controlled aircraft fly.

A remotely controllable flying machine, such as a remote control ultralight helicopter, has at least one rotor blade (104), the pitch (α) of which may be adjusted. The adjustment of the pitch (α) of the at least one rotor blade is achieved by means of a force, such as a torsion force directly applied to the rotation axis of the rotor blade. The force is generated by a magnetic field, variable by the electrical control of at least one coil (196) which is not part of an electric motor.

A method for remotely guiding a refueling boom of a tanker to engage with a fueling receptacle of an aircraft while the tanker and the aircraft are in flight. The method comprising: transmitting a polarized RF scanning pattern from one of the refueling boom and refueling receptacle; detecting the polarized RF scanning pattern at one or more cavity sensors disposed on the other of the refueling boom and the refueling receptacle; and controlling a position of the refueling boom relative to a position of the refueling receptacle based on the detected polarized RF scanning pattern at the one or more cavity sensors.

An aircraft navigation system and navigation method. The system comprises a civil-certified GPS-receiver for determining first position information based on C / A-GPS-signals, and a military-type GPS-receiver for determining a second position information based on P(Y)-GPS-signals. A monitoring unit detects a first abnormal condition during jamming conditions within the C / A-GPS-signals. The unit compares the first position information with the second position information and detects a second abnormal condition when a difference between these position information is larger than a threshold value for more than a threshold duration. Upon detecting an abnormal condition, an alert procedure is initiated. In remotely piloted aircraft, Command & Control link-loss is also monitored and during link-loss, a transponder code automatically indicates communication failure. When in such situation an abnormal condition is additionally detected, a transponder code indicates airborne emergency and, subsequently, the aircraft navigation system is switched to navigating based on position information from the military-type GPS-receiver.

A cellular type communications system for cellular telephone networks to operate, control and communicate with unmanned aerial vehicles and remote piloted vehicles, the system including a first near-ground region to communicate with devices near the ground, as well as one or more layers covering roughly the same areal extent as the ground region but which are separated from each other and also elevated above ground substantially, and within which an aerial vehicle may rely on communications using the cell-based communications network.

The invention provides a solid rocket carrying device carrying a remote-controlled aircraft, which includes: a rocket body, a fairing, a parachute, a carrier cabin, an anti-spray piston, a solid propeller, an empennage and a controller; the invention utilizes a solid rocket carrying a remote-controlled aircraft The carrying device carries the remote control aircraft to a certain height, and then throws the remote control aircraft out of the carrying compartment. The remote control aircraft starts to work after leaving the carrier cabin, which saves the energy consumed from the ground to the air, prolongs its endurance, and returns to the ground under its own power after the work is over; Back to the ground, and can be used repeatedly.

The invention discloses a remote-controlled aircraft with a cold-proof function, which relates to the field of unmanned aerial vehicles, and solves the problem that if the current unmanned aerial vehicle is used in a cold area, after the unmanned aerial vehicle lands for too long, its landing gear will be damaged. Hazard of freezing on the ground. The present invention includes the UAV body, outriggers, water tank, motor cabin, motor, landing gear, sprinkler head, cold water pipeline and hot water pipeline, the water in the water tank enters the motor cabin through the cold water pipeline, and then the water in the motor cabin passes through the heat The water pipe is transported to the water spray head at the bottom of the landing gear; when used in cold regions, the present invention can realize the cooling of the motor and the thawing of the landing gear at the same time; water cooling can be carried out to a specific motor as required, and it can also be used in the Hot water is output from four water spray heads for thawing.
