Viktiga resultat som projektet gav
This project aims to design a ~ 55mm diameter drone propeller with improved efficiency, production quality and reduced noise, resulting in longer battery life and quieter drones. This has delivered a approximate 20% reduction on the amount of torque required to produce 10g of thrust at 19k RPM. The project has also facilitated a closer relationship between Bitcraze and a new propeller supplier who can offer a higher propeller production quality and variance.
Långsiktiga effekter som förväntas
The goals for the projects can be divided into two broad categories, propeller performance and manufacturing quality. The newly designed propeller offers 20% torque reductions over the 17k to 19k RPM range. The delivered propellers are now better balanced. This reduces vibration, which in turn reduces signal noise on the on-board control systems and renders the drone a more accurate tool for Bitcraze’s in-house software developers and their clients.
Upplägg och genomförande
This project unfolded in 4 stages. The first stage, allowed all parties to collect information and share processes, to determine if anything in the respective workflows was going to incompatible. The second stage saw RMIT work with the collected information to devise a testing and simulation program to optimise the existing propeller and maintain manufacturability. In the third stage Gemfan took the optimised propeller and prepared it for mass manufacture. In the fourth stage, the tool is cut and the first run of injection moulded, optimised propellers come out of the tool.
