Methods of making a composite aircraft primary structure include selecting a compression moldable composite sheet molding compound; preparing a first and a second layup with the compression moldable composite sheet molding compound to form a first and a second 3D preform; and compression molding the first and the second 3D preforms to form a first and a second component part. Further, the first component part comprises first geometric joint features, the second component part comprises second geometric joint features, and the second geometric joint features are complementary to the first geometric joint features such that the second geometric joint features are configured to mate with the first geometric joint features. The method further includes assembling the aircraft primary structure by joining the first component part with the second component part by aligning and mating the first geometric joint features and the second geometric joint features; and securing the same.

A composite hybrid gear assembly includes a gear hub formed from a composite material and a gear head assembly. The gear hub includes a shaft region having an axially symmetrical external profile and a hub web region having a flared profile extending from the shaft region. The gear head assembly includes a head web region and a teeth region where the gear head assembly is fixed to the gear hub. Additionally, the composite hybrid gear assembly includes a first sleeve fixed to an external surface of the shaft region. An associated method of making a composite hybrid gear assembly is also provided.

Environment isolation structures may include a frame and flexible panels at least partially covering, and attached to, the frame. The frame may include multidirectional node connectors including multiple locations for attachment. At least some of the locations for attachment may be located on different sides of the multidirectional node connectors. Poles configured to telescope to selectively fixable lengths may include connectors affixed to longitudinal ends of the poles. Each connector may be configured to selectively attach to a respective location for attachment on a given side of a respective multidirectional node connector to form the frame.
