The addition of energy harvesting is investigated to determine the benefits of its integration into a small unmanned air
vehicle (UAV). Specifically, solar and piezoelectric energy harvesting techniques were selected and their basic functions
analyzed. The initial investigation involved using a fundamental law of thermodynamics, entropy generation, to analyze
the small UAV with and without energy harvesting. A notional mission was developed for the comparison that involved
the aircraft performing a reconnaissance mission. The analysis showed that the UAV with energy harvesting generated
less entropy. However, the UAV without energy harvesting outperformed the other UAV in total flight time at the target.
The analysis further looked at future energy harvesting technologies and their effect on the energy harvesting UAV to
conduct the mission. The results of the mission using the advanced solar technology showed that the effectiveness of the
energy harvesting vehicle would increase. Designs for integrating energy harvesting into the small UAV system were
also developed and tests were conducted to show how the energy harvesting designs would perform. It was demonstrated
that the addition of the solar and piezoelectric devices would supply usable power for charging batteries and sensors and
that it would be advantageous to implement them into a small UAV.
