The overall systems engineering project leadership is housed at the University of Colorado, Boulder. The task is to assure streamlining all technical work done by all four teams and assure smooth system integration of the Unmanned Aerial System (UAS). Individual students assigned to select sub systems work with the teams at the partner universities to develop the correct system interface documents.
On the technical side, the Boulder team (University of Colorado at Boulder) is responsible for the UAS Power and Propulsion. The propulsion system is a high powered electric motor capable of turning a large diameter (or multi-blade) propeller. The propeller is a folding prop to allow versatility in landing as well as an option for decreased drag gliding. The motor/propeller system is a pusher configuration with propeller mounted to the rear of the fuselage. Additional studies are being performed to optimize the propeller for silent flight while still providing the requisite performance to meet flight mission requirements. The power system is comprised of two primary LiPo battery packs; one for the flight systems and the other for payload systems. There will also be a secondary power source used as contingency power to primary systems (communications, control servos, and the motor) to allow for safe and recoverable landing if the primary packs fail or run out of energy. A power distribution board and voltage regulators is currently being designed to provide regulated power to all components.
