It has become tradition, apparently; one of my favorite tasks at work is still to organize, execute and support our famous workshops. After two successful workshop series about Formula 1 at the beginning of this year, we have offered a new workshop series about drone design.
The workshop series took place once a week, from October 15th until November 5th. In contrast to our former workshops, this time we have focused on makers and those who want to design or modify their own drone design.
During the 4th session, the participants investigated different development areas of an existing drone design from both perspectives—real world and simulation. The design was provided by Nathan Kau, a very talented young engineer, drone designer and high school student.
Curriculum of the Drone Workshop
The first session was about the optimization of the propeller. We investigated two different designs which differentiate the propeller’s shape and pitch, as well as its housing. A particularly conspicuous aspect is the dependency of the lift force from the pitch angle.
The second session of the workshop introduced our users to structural simulations of assemblies, which can be very challenging. The participants were introduced to the fundamentals of FEA and some advanced features like contact definition, ramping, and the influence of mesh refinement on the simulation result. From the designer’s perspective, we discussed how the load of the propeller will deform the drone’s arm.
Building on the knowledge gained in the previous sessions, the third session of the workshop covered virtual drop crash simulations. In contrast to the simulation that we set up before, a virtual crash test is a full transient simulation. Simulating the impact of the drone for several velocities helped us understand the critical falling velocity for our design.
Finally, in the fourth session, we investigated the impact of vibrations, which can have a negative impact on stiffness and maneuverability. The engine can cause periodic simulations because it contains a rotating body.
Thank you all for participating in our drone workshop, and stay tuned! We have many more challenges for you!
