Team Leader’s Remarks “Imagination and Knowledge Are keys, to the door that is Motivation” Vítor Teixeira Yes it’s true, PSEM’s not only developing a couple of the most advanced vehicles in Greenpow- er, but is also working as a mentor to the younger generations. Obviously, we know that we’re in a competition for the top places of the table, but the objective is not to teach other teams how to build a competitive or winning car, or reveal secrets of our intellectual property. In fact, our goal is to give them the necessary theoretical and practical basis for them to develop their critical thinking and find out ways to improve the performance of their current vehicles and design better cars from scratch. With friendly competition, open learning and knowledge sharing, the technological advances are far greater and faster. We’re all students and whatever our Greenpower status, there are always new/different things to learn. Imagination and knowledge are two keys to the door that is motivation. And if we give young students the knowledge key, with their imagination and motivation they’ll be able to do anything, and they will surely be more committed to learn autonomously and will perform better at school. 2

Siemens Innov Carbon Tub The latest vehicles’ monocoques developed by our team were produced by assembling multiple carbon fibre bulkheads to the bottom of the vehicle’s bodywork with structural adhesive. How- ever, for our newest prototype, we decided to venture out into the creation of a carbon tub (or a carbon monocoque). This structural component is separated from the aerodynamic bodywork, the last being assembled (and not glued) to the bottom and top of this structure. Therefore, in the future, each of these components can be opti- mized and updated without compromising each other. 3

vation Another advantage of the carbon tub is the greater rigidity, which combined with an optimiza- tion of the thickness of the core between the carbon layers, will allow us to minimize the weight of the vehicle to record values, without compromising its rigidity or safety. Regarding the rollbar, we were able to optimize the dimension and posi- tion of the steel tubes, in order to have the best of the three worlds: high safety and rigidity, regulation-compliant system and minimum possible weight. 4

alexandre Freira #teammates Beatriz Silva I am a 22-year-old Mechanical Engineering student and part of the Electronics Department. Luís Lopes I have learnt a lot in PSEM, from general workshop skills, such as milling and carbon fibre infusions, to various programming languages and soldering of electrical components. The best moments I lived in the team were the trips to England, in particular the first that I went on. I believe that GP21 can compete for 1st place in all races and the next model will be even better. I am in the 5th year of Electronic and Computer Engineering and I love music. I joined PSEM at the beginning of the 19/20 season and have been a part of the Electronics Department since then, having been re- sponsible for the development of the telemetry system. Being part of PSEM has been a very positive experience, since I learned to work with new programming languages ​a​ nd devel- oped other skills such as soldering. In this season I would like to have the opportunity to participate in the competitions, as it would be rewarding to see our car compete. I am Luís and I joined PSEM immediately after entering IST, in the Aerodynamics Department. I am a fan of football and Formula 1. Being on the project improved my skills in more complex CAD and simulation programs, however I think the social and team- work skills were the most important to be developed. One of the tests we did on GP19, in which the cooling system passed with excellence, was the most remarkable moment I lived in the team. I hope that with the end of the pandemic it will be possible to take the cars to competitions and win, as a reward for the team’s effort. 6

Greenpower Track Rockingham Motor Speeday is a racing track situ- ated in Northamptonshire, England with a 2,38km length. It was inaugurated in 2001 and since then became a place for competitions such as BTCC, Formula 3 and CART (until 2007). Furthermore, 9 it is a very special place por PSEM since it was in
