Efficiency optimisation of mass produced micro drone propellers.

Purpose and goal

The goal of this project is to deliver a reliable, balanced supply of efficient propellers that can be integrated into Bitcraze’s product offering at a competitive part price. The purpose of this initiative is to: - Better service Bitcraze’s clients who are needing longer battery life. - Reduce costs and time associated with quality control issues currently experienced with existing propeller suppliers. - Reduce vibration on the drones, which in turn reduces noise on the on-board control systems rendering it a more accurate research tool.

Expected results and effects

Bitcraze will work in collaboration with KTH University, RMIT University and RISE to set the parameters of a machine learning algorithm that will seek to generate a propeller design that balances torque, thrust and RPM to maximise efficiency. By leveraging RISE’s manufacturing expertise in combination with RMIT’s proven and proprietary methodology, Bitcraze aims to set up a supply of high quality, competitively priced propellers. Allowing Bitcraze to better serve the international research community and position themselves strongly in a burgeoning commercial space.

Planned approach and implementation

The project will unfold in 5 stages. Stage 1 - A document will be prepared that includes the recommended parameters for the optimisation algorithm. Stage 2 - The optimization takes place and is verified by real world testing of 3D printed prototypes. Stage 3 - The propeller is modified slightly to ensure it is able to be plastic injection moulded Stage 4 - A second round of printing and testing is performed to ensure performance after stage 3 changes Stage 5 - The tool is cut and the first production samples are tested. Small modifications to the tool are made if necessary.
