What Is the C-3 Project?
The C-3 Project (Combat Climate Change) is an industry supported quadruple-helix student project between KTH Royal Institute of Technology in Stockholm, Sweden, and Universidad EAFIT in Medellín, Colombia to develop an unmanned aircraft for atmospheric measurements for climate change research.
Mission Profile
The aircraft is designed to complete an ambitious mission to fly for up to 20km on a constant climb attitude, complete a power-off spiral glide between 0.5hr and 3.0hr collecting atmospheric data and ground images, and complete the mission by flying up to 20km to base.
Aircraft Design
A key characteristic of the aircraft was the use of a fully electrical propulsion system to respect the sustainability and climate change requirements, pushing the boundaries of the design space of an electrical aircraft to complete the mission.
A conventional aircraft configuration was selected with high aspect ratio slender wings for aerodynamic efficiency and an inverted V-tail for control efficiency and structural weight reduction.
