Abstract: A rotor blade for a rotary wing aircraft includes a leading edge and a trailing edge defining a chordwise direction. The leading edge defines a forward end of the rotor blade and the trailing edge defines an aft end of the rotor blade. The rotor blade has a center of gravity and an aerodynamic center along the chordwise direction. The center of gravity is aft of the aerodynamic center.

Abstract: A computer-implemented method and system for transmitting power and data together in a rotorcraft using a slip ring assembly is disclosed. According to one example, a computer-implemented method includes providing a slip ring assembly comprising a stationary element coupled to an airframe of a rotorcraft and a rotatable element rotatable relative to the stationary element and coupled to a rotor assembly of the rotorcraft. Power is transmitted from a power source associated with the airframe to an electronic device associated with the rotor assembly, the slip ring assembly being configured to complete an electrical circuit between the power source and the electronic device to provide power from the power source to the electronic device. Data is transmitted from a first data transceiver associated with the airframe to a second data transceiver associated with the rotor assembly via the electrical circuit completed by the slip ring assembly.

Abstract: A rotor system includes a rotor hub, a plurality of rotor blades supported by the rotor hub, and a fairing mounted to the rotor hub. The fairing includes an external surface exposed to an external airflow and an internal surface defining an interior portion. One or more heat generating components are arranged in the interior portion. A cooling system is arranged in the interior portion. The cooling system includes a first heat exchanger thermally connected to each of the one or more heat generating components, a second heat exchanger mounted to the fairing, and at least one fluid conduit extending therebetween so as to remove heat generated by each of the one or more heat generating components.

Abstract: A blending system is shown and described herein. The blending system may include a base including a motor, a blade selectively and operably engaged with the base, where the motor rotates the blade, a container having an open end and a lid configured to cover the open end. The blending system may also include an optical interlock detector that may include a camera positioned on the base and indicia positioned at a predetermined location on a lid, wherein the camera detects the indicia and position of the lid to permit operation of the blender.

Abstract: A hub for a rotary wing aircraft includes a plurality of rotor blades, and a heat dissipation system including an aerodynamic faring arranged outwardly of the hub. The aerodynamic fairing has an outer surface and an inner surface defining a component receiving zone. An electronic component is mounted to the inner surface of the aerodynamic faring in the component receiving zone.

Abstract: A device for measuring the maximum flow rate of a single forced expiration, comprises an elongated hollow body with inlet and outlet ends, a vane mounted to a shaft and rotatable within the body from a defined rest position, and an indicator to indicate maximum displacement of the vane from its rest position. The vane is shaped such that airflow from the inlet end past the vane causes the vane to rotate away from the rest position with the plane of rotation preferably being at about 90.degree. to the airflow through the elongated body.
