Sounds are generated by an aerial vehicle during operation. For example, the motors and propellers of an aerial vehicle generate sounds during operation. Disclosed are systems, methods, and apparatus for actively adjusting the position and/or configuration of one or more propeller blades of a propulsion mechanism to generate different sounds and/or lifting forces from the propulsion mechanism.

Aerial vehicle adaptable propeller blades

Described are apparatus and processes for reconfiguring aerial vehicles, such as unmanned aerial vehicles (UAV) during navigation of the aerial vehicle between a maneuverability configuration and an efficiency configuration. When an aerial vehicle needs to be able to quickly maneuver in any direction (vertical, horizontal, pitch, roll, yaw) it is operating in a maneuverability configuration. When configured to operate in the maneuverability configuration, the primary function of the aerial vehicle configuration is to increase maneuverability of the aerial vehicle. When the aerial vehicle is navigating in a direction that is substantially horizontal, for example when navigating between locations, it may be configured to operate in an efficiency configuration. When configured to operate in the efficiency configuration, the primary function of the aerial vehicle configuration is to increase efficiency of the aerial vehicle and reduce power consumption.

Configurable aerial vehicles

Sounds are generated by an aerial vehicle during operation. For example, the motors and propellers of an aerial vehicle generate sounds during operation. Systems, methods, and apparatus may actively adjust the position and/or configuration of one or more propeller blades of a propulsion mechanism to generate different sounds and/or lifting forces from the propulsion mechanism.

A dual protection inner seal washer employs a radially outward metallic portion having a dielectric coating and a radially inward polymeric portion engaging the metallic portion at an interface with an interference fit. The polymeric portion has at least one tapering compression surface to engage a surface of a structure proximate a hole and further has a fastener element contact surface to engage a mating surface on a fastener system element. Torqueing of the fastener element compresses the at least one compression surface inducing a predetermined pressure in the polymeric portion in a joint created by the fastener element and structure.

A two-piece, one-sided-installation fastener system may have an internally-threaded sleeve having a shank and a sleeve head. The fastener system may include an externally-threaded core bolt having a frangible driving provision and a core bolt head.

Delivery area guidance may be provided to an unmanned aerial vehicle (UAV) via one or more delivery area guidance vehicles. For example, a UAV may be programmed to fly to a delivery area (e.g., a neighborhood, a block, a large residential or commercial property, and/or another area associated with landing and/or a delivery). Approaching the delivery area, the UAV may deploy one or more delivery area guidance vehicles. A guidance vehicle may be configured to maneuver a distance from the UAV, and to assist in guiding the UAV into the delivery area to the UAV.

Deployable delivery guidance

A switch for switching power to a load of a vehicle may be described. In an example, the switch may include a number of members configured to move between switch positions in a predefined order such that a load and a power source are electrically coupled or electrically decoupled via the switch based on the predefined order. In particular, a first member may be configured to move to a first switch position and form a first electrically conductive path having a first electrical property. A second member may be configured to move to a second switch position and form a second electrically conductive path having a second electrical property different from the first electrical property. A third member may be configured to move the second member based on movement of the first member to the first switch position such that movement of the second member to the second switch position may occur based on the movement of the first member to the first switch position.

A fastener system for composite structure providing electromagnetic energy protection has a shank with a threaded portion on a first end of the shank terminating in a lead-in portion. A head is present on a second end of the shank. The shank is adapted for intimate conductive contact with an inner surface of an interference fit hole.

Modified shank fasteners for electromagnetic effect (EME) technology

Fasteners are inserted into a stack of members and terminated with parts having at least one of a dry dielectric coating and a dry dielectric seal at select locations to protect against electromagnetic effects (EME).

Fastener systems that provide EME protection

Fasteners are inserted into a stack of members and terminated with parts having at least one of a dry dielectric coating and an inner dry dielectric seal at select locations to protect against electromagnetic effects (EME).

Structural blind fastener and method of installation

A fastener system for composite structure providing electromagnetic energy (EME) protection incorporates a fastener having a head with an engagement surface and a shank having a threaded end. A nut is received on the threaded end of the fastener, with the nut also having an engagement surface. At least one of the head engagement surface and the nut engagement surface incorporates a reduced area portion for engagement of a first mating surface or second mating surface, respectively.
