Abstract:
The present invention provides 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 and at least two rotor blades coupled to a rotor head which in turn is connected to the rotor shaft. The rotor assembly further comprises a non-rotating swash plate through which centre the rotor shaft runs, being adjusted to tilt around its entire radial axis. A respective pitch hinge for each rotor blade connecting said respective rotor blade to the rotor head is provided, wherein a hinge axis which the pitch hinge rotates around is generally parallel to and is positioned in front of the longitudinal centre axis of the respective rotor blade in the rotational direction. A respective guide member for each rotor blade is connected to an inner blade tip. The inner blade tip is positioned in front of the hinge axis in the rotational direction, and the guide member is adjusted to follow an upper surface of the non-rotating swash plate when the rotor assembly rotates. One or more forces, e.g. a magnetic and/or an aerodynamic force, are applied on the rotor blades being sufficiently strong to create a valve effect on the pitch hinge pressing the guide members downwards against the non-rotating swash plate, whereby movements of the non-rotating swash plate are transferred to blade pitch movements of the rotor blades.
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:
The present invention relates to a system and a method for measuring and determining the depth, offset and translation in relation to one or several features in the field of view of an image sensor equipped UAV. The UAV comprises at least an autopilot system capable of estimating rotation and translation, processing means, height measuring means and one or more imaging sensor means. Given the estimated translation provided by the autopilot system, the objective of the present invention is achieved by the following method; capturing an image, initiating a change in altitude, capturing a second image, comparing the images and the change in height provided by the sensor to produce a scale factor or depth. If depth is estimated, then calculating the scale factor from the depth, and calculating the actual translation with the resulting scale factor.
Abstract:
The present invention provides 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 coupled to a rotor head which in turn is rotationally coupled to the rotor shaft, a rotating swash plate through which centre the rotor shaft runs, with at least three fly bars extending from and being distributed around said centre provided with a weight element on respective outer tips. The swash plate is further being rotationally coupled to and synchronized with the rotor shaft and adjusted to tilt in all directions relative to a plane perpendicular to the rotor shaft, wherein the rotor head is hinged to the rotor shaft in one direction so that the rotor head and the rotor blades jointly are able to tilt around their concurrent longitudinal axis, but not around their traversal axis. The rotating swash plate is also coupled to the rotor head by two tilt links being hinged to both the rotating swash plate and the rotor head, one at each side of the longitudinal axis of the rotor head, providing 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 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:
Den foreliggende oppfinnelse angir en fremgangsmåte og en fjernkontroll for styring og overvåking av omkringliggende områder fra en Unmanned Aerial Vehicle (UAV) av en operatør med en fjernkontroll som inkluderer en flykontrollskjerm. Utførelsesformene viser en overraskende fordelaktig effekt ved styring og overvåkning av omgivelsene til et UAV ved å kombinere bildet tatt av et UAV-kamera med en transparent overlappende posisjons- og navigasjonskart som tilveiebringer en persepsjon slik at føreren skal ha en komplett oversikt over situasjonen, ved å benytte en felles del av en flykontrollskjerm slik at det dermed ikke er nødvendig å skifte øyefokus. Visning av bilder og posisjons- og navigasjonsinformasjon på måten som er beskrevet har vist seg ikke å forstyrre hverandre, snarere tvert imot.
