A satellite dispenser is disclosed. In various embodiments, a satellite dispenser as disclosed herein includes a dispenser body defining an interior cavity configured to receive a payload; and a composite guide rail comprising a groove configured to receive at least a portion of a payload, the composite guide rail having an orientation that substantially aligns a longitudinal axis of the groove with an ejection axis of the dispenser.

A composite transmission shaft includes a shaft portion, and a flanged end fitting. The flanged end fitting comprises a flared sleeve comprising a tubular portion and a flared portion, and a reinforcement portion fixed to the flared portion of the sleeve. The flanged end fitting and shaft portion have been resin transfer moulded together to form the transmission shaft.

Disclosed is a thin-wall bonded self-lubricating plate, the composite material structure thereof being composed of a surface self-lubricating layer, an intermediate bonding layer, and a metal backing layer. The surface self-lubricating layer includes polytetrafluoroethylene, ultrahigh molecular weight polyethylene, etc. The surface self-lubricating layer thereof is thicker than an ordinary sintered self-lubricating material, thereby reducing vibration and prolonging the service life. Components, such as bushings, gaskets, sliding plates, composite bearings and other special-shaped members, made of the thin-wall bonded self-lubricating plate, have broad application prospects in low-speed rotation and relative sliding parts of vehicles, general machinery, office furniture, etc.

Provided is a sliding member for a journal bearing. The sliding member includes a back-metal layer and a sliding layer, and has a partially cylindrical shape. The sliding layer includes a synthetic resin and has a sliding surface. The sliding layer has a linear expansion coefficient KS in a direction parallel to a circumferential direction of the sliding member, a linear expansion coefficient KJ in a direction parallel to a center axis direction of the sliding member, and a linear expansion coefficient KT in a direction perpendicular to the sliding surface, and the linear expansion coefficients KS, KJ, and KT satisfy the following relations (1) and (2): Relation (1): 1.1≤KS/KJ≤2; and Relation (2): 1.3≤KT/{(KS+KJ)/2}≤2.5.

Provided is a sliding member for a thrust bearing. The sliding member includes a back-metal layer and a sliding layer, and has a partially annular shape. The sliding layer includes a synthetic resin and has a sliding surface. In a center line region of the sliding layer, the sliding layer has a linear expansion coefficient KS in a direction parallel to a circumferential direction of the sliding member, a linear expansion coefficient KJ in a direction parallel to a radial direction of the sliding member, and a linear expansion coefficient KT in a direction perpendicular to the sliding surface, and the linear expansion coefficients KS, KJ, and KT satisfy the following relations (1) and (2): Relation (1): 1.1≤KS/KJ≤2; and Relation (2): 1.3≤KT/{(KS+KJ)/2}≤2.5.

A curable composite bush for an aircraft joint comprising a generally hollow cylindrical body formed from a matrix material impregnated with a reinforcement material substantially composed of fibers, the fibers being oriented in a generally circumferential direction about a longitudinal axis of the bush. The body may define a plurality of corrugations extending between an inner and an outer diameter of the bush to improve the compressibility of the bush in a direction substantially collinear to a longitudinal axis of the bush.

A flexible composite driveshaft is formed by modifying the shape of a preliminary composite driveshaft. A fiber tape is applied to a temporary mandrel using automated fiber placement to form a preliminary composite driveshaft having a flexible shaft element with an initial geometry. The temporary mandrel from the preliminary composite driveshaft is removed and the initial geometry of the flexible shaft element is modified to form the flexible composite driveshaft having a flexible shaft element with a final geometry.
