Embodiment Construction

[0021] 1 Overview

[0022] The present technology generally relates to unmanned aerial vehicles (UAVs) with pitched propellers, and related systems and methods. In a particular embodiment, the drone includes a spherical motor supporting one or more rotating propellers. Spherical motors can be used to tilt the propeller shaft without tilting the drone's body. The propeller shaft itself may be driven by the spherical motor, or by an additional propeller motor carried by one or more components of the spherical motor. This arrangement is expected to offer several advantages over conventional UAV propulsion systems, described further below.

[0023] For the sake of clarity, the following description does not set forth several details describing structures or processes that are well known and often associated with UAVs and corresponding systems and subsystems, but that may unnecessarily obscure some aspects of the disclosed technology. important aspect. Furthermore, while the fo...

Abstract

Unmanned aerial vehicles with tilting propellers, and associated systems and methods are disclosed herein. A representative unmanned aerial vehicle (UAV) apparatus includes an airframe (110), a plurality of spherical motors(120) carried by the airframe(110), and a plurality of rotatable propellers(163), with individual propellers(163) carried by corresponding individual spherical motors(120). Thespherical motors (120) can include a spherical or partially spherical rotor(126) supported relative to the airframe (110) with multiple stators(122). The spherical motors (120) can be used to tilt thepropeller shafts without tilting the airframe of the UAV.

Description

technical field [0001] The present technology generally relates to drones with pitched propellers, and related systems and methods. Background technique [0002] Unmanned Aerial Vehicles (UAVs) can operate autonomously or under the control of human controllers off-site. Accordingly, drones may perform a wide variety of tasks that would be dangerous, expensive, and / or otherwise objectionable to the performance of a manned aircraft. Representative tasks include crop monitoring, real estate videography, building and other structure inspections, fire and security missions, border patrol, and product delivery, among others. A representative task involves acquiring images via a camera or other image sensor onboard the drone. The challenge with acquiring this kind of imagery with a drone is that, since the drone is airborne, it can be difficult to stabilize the image, at least under certain conditions, including those in which the drone is conducting maneuvers. Accordingly, ther...
