Abstract: A rotor assembly for helicopter vehicles for providing an easy way of controlling pitch, roll and lift of the aircraft by respective servo actuators. The rotor assembly has a rotor shaft, at least two rotor blades, a rotor head, and a non-rotating swash plate. The rotor assembly also includes a pitch hinge for each rotor blade connecting each rotor blade to the rotor head. The rotor assembly also includes a guide member for each rotor blade. As the rotor assembly rotates, the guide members are in substantial contact with an upper surface of the non-rotating swash plate. Forces such as magnetic and/or an aerodynamic forces are applied on the rotor blades and are sufficiently strong to create a valve effect on the pitch hinge, which in turn maintains contact between the guide members and the non-rotating swash plate.

Abstract: A rotor assembly for helicopter vehicles for stabilizing the aircraft and thus providing an easy way of controlling pitch and roll of the aircraft by respectively associated magnetic actuators. The rotor assembly comprises a rotor with two flexible rotor blades, a rotor head rotationally coupled to the rotor shaft, a rotating swash plate, with at least three fly bars extending therefrom. The swash plate is rotationally coupled to the rotor shaft and adjusted to tilt in all directions relative to a plane perpendicular to the rotor shaft. The rotor head is hinged to the rotor shaft in one direction so that the rotor head and the rotor blades jointly are not able to tilt around their transversal axis. The coupling between the rotating swash plate and the rotor head provide synchronized tilt movements between the rotor head and the rotating swash plate around the longitudinal axis of the rotor head.

Abstract: The embodiments herein disclose a personal UAV kit for storing, preparing and remote control of micro UAVs (40). The UAV kit includes a base unit (10), a control unit (30) and at least one UAV. The UAVs can typically be a winged aircraft with foldable wings or a helicopter with a two-bladed or foldable rotor. The base unit comprises UAV compartments for housing at least one UAV, bay (14) for storing the control unit, batteries and electronic components for charging, communication, control and processing and storing of data. In addition, the system includes an eye near display device for viewing system information and sensor data, typically live video, transmitted from the UAV.

Abstract: Local wind fields can be predicted if both the airspeed and the ground speed of the helicopter are known. An aircraft that uses an inertial navigation unit, autopilot and estimator allows a measure of ground speed to be known with good certainty. The embodiments herein extends this system to allow an estimate of the local wind field to be found without actively using an airspeed sensor, but instead combining the measurements of an accelerometer and a drag force model and a model of controlled aerodynamics of the aircraft to estimate the airspeed, which again can be used to estimate the local wind speed.

Abstract: The present invention discloses a control stick for controlling an UAV formed by a bar with buttons on the bar head and a GUI displaying airplane like icons providing feedback of current steering control status of a UAV.

Abstract: The embodiments herein disclose a method and a remote control for controlling and monitoring surrounding areas of an Unmanned Aerial Vehicle (UAV) by an operator with a remote control comprising a flight display. The embodiments disclose a surprising advantageously effect for the purposes of controlling and monitoring the surroundings of a UAV by combining the image captured by a UAV camera with a transparently overlaid positional and navigation map providing a perception enabling the operator to have a complete overall view of the situation, utilizing a common screen section of a flight display and thereby not having to shift eye view. Viewing images and positional and navigation information in the way described has shown not to interfere with each other, rather on the contrary.

Abstract: A method and device for precise control of and controller design for aircrafts consisting of at least one spinning part and at least one non spinning part is provided. The required torques for control of the spinning parts and for the non-spinning parts are continuously and individually calculated. All torques are combined to get the correct torque for the complete aircraft. Doing this, it's possible to continuously apply the correct torque, both correctly distributed among the roll and pitch axes (correct angle), and correct magnitude. The result is a decoupling of the roll and pitch axes, simplifying controller design to a design of two single input single output controllers, one for each axe.
