Abstract: A rotor-blade weight-carrier system includes a weight carrier positioned within a rotor blade and a plurality of weights positioned within the weight carrier.

Abstract: A method of designing a rotor blade for a rotary aircraft includes establishing a target thrust-weighted solidity of the rotor blade, calculating a reverse flow circle of the rotor blade at a target forward speed of the rotary aircraft, inboard of the reverse flow circle, decreasing chord of the rotor blade relative to a baseline rotor blade possessing the target thrust-weighted solidity, and outboard of the reverse flow circle, increasing the chord of the rotor blade relative to the baseline rotor blade. The rotor blade possesses the target thrust-weighted solidity of the baseline rotor blade and improved stall margin or speed margin at the target forward speed relative to the baseline rotor blade.

Abstract: A combination suction and irrigation device for a medical procedure. The device includes an elongated body having a proximal end and a distal end and defines an open channel that extends from the proximal end to the distal end. The open channel is open at both the proximal end and the distal end. A suction port is in communication with the open channel and is connectable to a source of suction. An irrigation port is in communication with the open channel and is connectable to a source of irrigation fluid. A valve selectively opens and closes the open channel to flow relative to the suction port and to the open proximal end, and to flow relative to the irrigation port.

Abstract: A balance weight assembly for a rotor blade of a rotorcraft. The balance weight assembly includes a balance weight pocket formed by a balance weight tray and a cover. The balance weight tray has an upper surface including a lip region extending outwardly from a projected region with an outboard boss. A balance weight receiving cavity is recessed from the upper surface and contains a plurality of balance weights. The projected region is disposed within an opening in a hollow blade spar such that the outboard boss of the balance weight tray has a contact relationship with an outboard surface of the opening. The cover is coupled to the balance weight tray such that the lip region of the balance weight tray and at least a portion of the cover have a clamping relationship with the blade spar, thereby coupling the balance weight pocket to the blade spar.

Abstract: Methods and articles of manufacture for treating patients with degenerative bone are provided. The methods are useful to improve bone quality in a localized area of a degenerative bone (e.g., osteopenic or osteoporotic bone), such as by improving BMD to be substantially similar to BMD in an average, healthy individual at the age of peak BMD. The methods can comprise forming a void in a localized area of the degenerative bone and filling the void with a bone regenerative material that causes generation of new, healthy, natural bone material. The articles of manufacture can comprise kits formed of various materials useful in the inventive methods for improving bone quality.
