Abstract: In some embodiments, an aircraft may have components with one or more channels configured to receive one or more rigid tubes passing through one or more components of the aircraft. A tube may be disposed within a first channel of a first component of the aircraft and may pass into and through a second channel of a second component of the aircraft. The tube may improve positioning and fit of the modular components of the aircraft, thereby improving stiffness and performance of the aircraft. The tubes also may improve efficiency when assembling the aircraft and coupling modular components of the aircraft to one another. Further, conductive wiring components of the aircraft may be routed internally within the tubes to achieve improved wire routing management and protection for wiring components.

Abstract: An antenna system is disclosed including a GPS antenna which is driven by an articulator in an opposite direction to aircraft roll. Aircraft roll is sensed by an onboard navigation system and translation module sends a signal to a processor which provides a drive signal to the articulator. As the aircraft rolls in one direction, the antenna is driven oppositely to maintain the vertical orientation of the antenna.
