A team of researchers in China has unveiled what they describe as the world’s first open-source flight control system designed specifically for bamboo-frame drones, helping the push for low-cost, eco-friendly unmanned aerial vehicles (UAVs).
The system, developed by researchers at Northwestern Polytechnical University’s school of civil aviation, aims to solve a long-standing bottleneck in sustainable drone design: integrating non-traditional materials such as bamboo with high-performance autonomous control.
Unlike conventional airframes made of composite materials, bamboo structures introduce low-frequency vibrations – typically in the 8-20 hertz range – that standard flight controllers struggle to handle.
The wings are made from bamboo, making it 20 per cent lighter and considerably cheaper than a carbon fibre device, according to state news agency Xinhua. The bamboo-based material used in the unmanned aerial vehicle costs about a quarter of the price of carbon fibre cloth. The UAV completed its maiden flight in northern China last month, reaching speeds of 62 mph during its first flight. The project explores how natural materials can be combined with modern engineering to create lighter and more sustainable aircraft structures.
During the initial test flight, the drone demonstrated stable performance and aerodynamic efficiency while reaching high speeds. The experiment highlights how bio-based materials could play a role in future aerospace manufacturing, reducing reliance on carbon intensive materials used in many aircraft components.
Bamboo fibre is known for its exceptional strength-to-weight ratio, making it an attractive alternative to traditional composite materials. By processing bamboo into high performance fibers and combining it with advanced structural design, engineers were able to create a drone frame that is both durable and environmentally friendly.
