  • Aerial vehicle takeoff and landing system, aerial vehicle takeoff and landing apparatus, and aerial vehicle
    Patent number: 11905037
    Abstract: An aerial vehicle takeoff and landing system, an aerial vehicle takeoff and landing apparatus, and an aerial vehicle capable of reducing the influence of the ground effect and capable of taking off and landing smoothly even in a comparatively small and limited space. A pair of rails are arranged side by side with a gap therebetween, and are arranged with a space in an extension direction on at least an under side and one end side. An aerial vehicle has a suspension portion provided at an upper portion thereof so as to be inserted between the rails from the one end side. With the suspension portion is inserted between the rails, the aerial vehicle can be suspended at a predetermined landing position of the rails, and the aerial vehicle suspended at the landing position can take off.

  • PASSIVE GUIDANCE MECHANISM AND FLYING OBJECT LANDING SYSTEM
    Publication number: 20230045539
    Abstract: A passive guidance mechanism enables smooth guiding to a desired position; and a flying object landing system enables smooth guiding to and landing at a desired position. A pair of guide rails are arranged side by side with a space therebetween, and are provided so that the space increases toward one set of tips of the guide rails. One guide rail is supported so as to be rotatable about a first shaft extending in a direction perpendicular to a plane including the guide rails, at or near the tip of the guide rail. The other guide rail is supported so as to be rotatable about a second shaft extending in a direction perpendicular to the plane including the guide rails, at or near the tip of the guide rail.
