Abstract:
(EN) A mandrel for use in manufacturing a spar having a spar cavity is provided including a first component, a second component, and a center component. The first component is configured to define at least an interior first surface of the spar cavity. The second component is configured to define at least an interior second surface of the spar cavity and form a space between the first and second components. The second component has a second side arranged in contact with a first side of the first component. The center component is arranged within the space to separate the first and second components and to engage at least a portion of each of the first and second components to retain the first and second components in a desired position.
