Kōkako, Human Powered Aircraft

Kōkako is the University of Auckland’s first attempt at designing and building a fully human-powered aircraft, an ambitious project that pushes the boundaries of ultra-lightweight engineering, aerodynamics, and mechanical efficiency. The aircraft is a 30-metre wingspan carbon fibre monoplane weighing under 40 kg, designed to fly using only the pilot’s pedalling power.

As Transmissions Lead, I head a team of 10 responsible for designing and building the entire drivetrain, from the pilot’s pedals through to the propeller hub. Our focus is on maximising power transfer efficiency while keeping weight and friction to an absolute minimum. We’ve prototyped and tested multiple drive systems, including belt, chain, and custom cable mechanisms, and are currently building a full-scale test rig and simulator for fine-tuning our design.

The project has challenged me to work across structural design, mechanical simulation, material selection, and team coordination. It’s a rare opportunity to apply real-world engineering skills to a truly unique goal: powered, sustained human flight, using nothing but clever design, composite materials, and the strength of one person.
