In 2022 a group of students from the UNSW Faculty of Engineering proved a theory first proposed over 100 years ago: that ancient boomerang technology could be used for vertical flight.
Now participants from the project are teaming up with the new UNSW First Nations Engineering and Science Society (FNESS) to showcase Indigenous innovation and inspire the next generation of First Nations students.
The idea that the boomerang could be adapted for vertical flight was proposed by First Nations inventor and Ngarrindjeri man David Unaipon in 1914.
Unaipon is perhaps most well-known for his modern mechanical sheep shears that revolutionised the wool industry and generated economic windfall for Australia, leading to him being immortalised on the Australian fifty dollar note.
However, Unaipon was also fascinated by perpetual motion and aerodynamics, and theorised that two boomerangs working together could generate vertical take-off, effectively conceptualising the modern helicopter.
It was this theory that the team from UNSW Engineering sought to prove, in a challenge filmed for an SBS NITV and Channel 10 series (aired in 2023) called The First Inventors which explores and celebrates the knowledge and innovations of First Nations peoples.
The team recognised that the boomerang shares many characteristics with the modern-day aerofoil – the design behind the wings of jets, propellers, engine blades and helicopter rotors – and worked to combine these ancient design principles with modern drone technology.
Using 3D printing to prototype and produce models for testing, the team found their drone design to be successful.
Dr Sonya A Brown, Senior Lecturer in Aerospace Design at the UNSW School of Mechanical and Manufacturing Engineering, led the challenge in 2022.
At the time, she said the team had “demonstrated that boomerang technology can lead to propulsion, particularly vertically taking off and landing on the ground,” proving Unaipon was decades ahead of his time.
