Our superbike reveal got a lot of media attention all over the world! We did a course on how to handle fire outbreaks and we had two cool filming moments. In the meanwhile, we continued working on our superbike to have it ready for its first dyno test! 

News

After the reveal on the 26th of May, it was time for us to continue working on our superbike to make everything ready as soon as possible. Last week we had a retrospective meeting to evaluate the past year and see what could be done differently next year. Besides that, we did a lot of filming. We filmed together with the University of Twente for a video clip that will be shown during the Opening of the academic year coming September. We also made a new movie with the other student teams of Twente, in collaboration with the Student Union.
With the reveal of the Delta-XE, we got a lot of media attention throughout the world! We did get a lot of publications in Europe, and especially in Italy. Among others, however, we also managed to distinguish ourselves with our new superbike in the United States, India, China, Russia, Malaysia, and Indonesia, which makes us really proud! 
As we are working with electricity and high voltage circuits, we of course need to think about our safety and the safety of others. Therefore some of our team members did a course on how to handle fire outbreaks. 

Partner highlights

K3D is one of our first-row partners this year. They evaluated and checked the design we made for the footpegs of the Delta-XE. After that, they 3D-printed both left and right footpeg (topology optimized) and they provided the materials needed to do this printing. 
We are happy to announce our partnership with Becker Watersnijtechniek. With their accurate water cutting technique, they cut the busbars we use in our superbike. With custom-shaped busbars, the current of the battery modules can flow over the shortest path. This made it possible for us to improve the current capacity and the compactness of the battery modules. 
For the first time this year, we collaborate with AFAM. They helped us in choosing the right sprockets and chain for our new superbike. Besides that, they provided us with components needed during testing and racing.

A word from our Chief Chassis

This month we have been very busy with testing, testing, and testing. We have seen on our dyno that the electric motor can handle the torque we designed it for. Lubrication of the gearbox also works as desired and the cooling systems can keep everything cool. We tested on full torque, but not on full power yet. This means that there is still some way to go. However, everything looks promising! In the last days of this month, we assembled the whole bike again. Now it is almost ready to leave for a big dyno test at one of our partners where we will test full power.

Not only are we aiming for better superbikes every year, but we also want to become more and more professional. For the chassis team, this means that we want to provide a great basis for the next team to build upon. And thus we are busy with finishing up documentation and updating protocols regarding designing, workshop safety, etc. This ensures that as little as possible of the knowledge is lost during the transition from us to the new team.

A word from our Chief Powertrain

We as powertrain have reached an amazing achievement this month by finalizing the testing of our electric motor on the dynamometer. We have done a characterizing test, which gives us loads of data about how the motor can be operated and where the most efficient and powerful regions are. From the data we collected, we can directly find the MTPA line, the most efficient operating points from low to medium speed. Now we are busy analyzing this data to find the MTPV line, which gives us the maximum amount of torque at high speeds as well. There was a lot of equipment necessary to make all this testing possible, which gave us a good opportunity to also test the supporting electronics and hardware.
We have had almost the entire bike laid out and functional when running the motor. This way, we were able to verify our communication, our charging, our battery management system, and much more. All this didn't work right away, of course, it took a lot of tinkering with the code and the connections between the boards to get everything to work together. Besides this, the chassis team has redesigned the battery casing and we are installing the batteries, BMS, and all other supporting as I am writing this. The coming month is a month in which we do a lot of testing and hopefully, see the bike on the track. We are super excited about seeing what the bike can do and we hope you are too!
