Abstract:
Various embodiments provide a method for improving crosswind stability of a propeller duct. The method comprises defining an initial duct section based on a predetermined airfoil section having an initial value of a geometric parameter such that the geometric parameter of a portion of the initial duct section has the initial value. The method also comprises determining fluid flow paths around the initial duct section when subject to a crosswind having a predetermined crosswind speed. The method further comprises varying the initial value of the geometric parameter of the initial duct section to a threshold value which causes separation of fluid flow paths at a windward side of the initial duct section at and above the predetermined crosswind speed to form an improved duct section. Various embodiments provide a corresponding apparatus, system and/or computer readable medium.
Abstract:
A connector for connecting a supporting shaft to a member, comprising a male connector (12) provided with a male engagement element (16a, 16b) and a female connector (14) comprising a female engagement opening for engaging the male engagement element (16a, 16b) therein. The male (12) or female connector (14) being connectable to the member in use. The connector also comprises a receiver (28, 41) provided on at least one of the male (12) or female connectors (14) for receiving the shaft on use. A spring biased lock mechanism (18a, 18b) is also provided on the male connector (12) or the female connector (14) for locking the male (12) and female connectors (14) together when the male engagement element (16a, 16b) engages the female engagement opening.
Abstract:
Various embodiments provide a portable electronic device holder (400, 500, 600, 700, 900, 1100, 1400) for a passenger seat (202), including a longitudinal clamping structure (420, 520) having a generally L-shaped cross-section. The clamping structure includes a supporting flap (422, 522) forming an L-base of the generally L- shaped clamping structure and configured to support a portable electronic device, and a clamping flap (424, 524) forming an L-leg of the generally L-shaped clamping structure and configured to clamp the portable electronic device against a surface (650) abutting the portable electronic device. The portable electronic device holder further includes a mounting element (410, 510) for slidably or titlably mounting the clamping structure to the passenger seat.
Abstract:
Various embodiments provide a method for installing a seat suspension on a seat frame having a first side frame member and a second side frame member opposed to and spaced apart from each other. The method may include moving a retainer on a first side of the seat suspension in a direction substantially perpendicular to a plane defined by the first and second side frame members for fastening onto a support member on the first side frame member; and moving a retainer on a second side of the seat suspension in the direction substantially perpendicular to the plane defined by the first and second side frame members for fastening onto a support member on the second side frame member. The second side of the seat suspension is opposed to and spaced apart from the first side of the seat suspension.
