Abstract: A propeller comprising a hub, a blade, and a hinge is disclosed. In various embodiments, a blade includes a neck portion angled away from a plane of rotation of the hub, wherein the blade has a longitudinal axis extending through the blade and running from a tip of the blade to an end of the neck portion, and a dihedral angle of the blade is an angle of the blade relative to the plane of rotation of the hub. The hinge includes a pivotal link, and connects the blade to the hub, wherein the hinge has an axis of rotation that is offset from a line perpendicular to the longitudinal axis of the blade, and responds to forces acting on the blade to vary a pitch of the blade including causing the blade to be at a lower pitch and higher dihedral angle in a first mode.

Abstract: In an embodiment, a system includes a frame configured to support a load, a first set of wheels provided on the frame, a second set of wheels provided on the frame, and a controller. The first set of wheels is configured to descend or ascend in response to the controller, and is oriented to move in a first direction. The second set of wheels is configured to descent or ascend in response to the controller, and is oriented to move in a different direction from the first direction. The controller configured to control the descent and ascent of the second set of wheels and the first set of wheels.

Abstract: A hinged propeller comprising a hub and one or more blades is disclosed. In various embodiments, a blade is connected to the hub via a hinge, wherein at least a substantial part of the blade has a longitudinal axis that is substantially parallel to a line extending radially from a center of the hub, and wherein the hinge has an axis of hinge rotation that is oriented at a non-zero acute angle to a line that is perpendicular, in a plane of rotation of the hub, to said longitudinal axis.

Abstract: A multicopter with boom mounted rotors is disclosed. In various embodiments, a multicopter includes multiple rotors, each mounted substantially horizontally on a distal end of a boom. The multicopter further includes a plurality of boom extensions, each boom extension being associated with a corresponding boom and each boom extension being configured to extend an associated distal end of said corresponding boom by an amount determined based at least in part on a swept area associated with a rotor mounted at or near said associated distal end. The multicopter includes a material, such as netting, secured to the aircraft and of a size sufficient to reach a far end of one or more of said boom extensions.

Abstract: An aircraft includes a float which provides buoyancy when the aircraft floats on a surface of water. The aircraft also includes a rotor where the rotor is configured to rotate in a horizontal plane and blow a wake across a side of the float. The rotor and the float are positioned relative to each other such that there is no aerodynamic separation between the wake blown by the rotor and the side of the float.

Abstract: A float has a front-to-back length, a width, and a height where the front-to-back length of the float is strictly greater than the height of the float which in turn is strictly greater than the width of the float. At least a bottom portion of the float is watertight. The float includes an access panel to access the inside of the float. A battery is inside the float and is accessible via the access panel.
