Team Hare Sponsorship- What are Aerodynamics?
As you probably already know, metals4U are sponsoring the Formula Student team from the University of Huddersfield for this racing season. We are delighted to be able to put our name to this amazing endeavour. The team of young men and women are working around the clock to ensure that every element of this year’s car is performing to the highest standard.
Last week, Team Hare revealed the new chassis design for the competition, here is the CAD presentation to give you an idea of what the final build will look like.
Now we can see what the final build will look like, we can start to appreciate just how much work has already been done this season.
The design of the aero package (front and rear wings, nose cone,sidepods, floor diffuser and bodywork) is not just to look good, every single element has to ensure that the car is subjected to minimal drag and maximum streamlining for optimal performance…Think bullet rather than parachute!
The aerodynamics team have been busy during the planning stage to see how they can work with the drag and lift forces that are created when air passes around and over an item- particularly when that item is travelling at speed- they need to be able to create a perfect balance of keeping the car securely on the road, while minimising the drag forces that will slow it down unnecessarily or create instability.
Due to the costings of the bodywork construction and not having a full size wind tunnel, Team Hare have come up with a solution to testing the aerodynamic performance without creating a full size body kit. ‘Experimental Designs’ have 3D printed a 10th scale model of the aero package to enable Team Hare to test in the windtunnel to ensure their CFD (Computational fluid dynamics) predictions are accurate before investing in the full size, and full cost, componants.
This week we caught up with the aerodynamics team led by Charlie May and Rafael Doherty to see how they were getting on, they had this update for us;
“The Aerodynamics department has focused on ease of manufacturability this year whilst also ensuring a beneficial aerodynamic performance package is created. Due to struggles within the manufacturing of aerodynamic components in recent years, simplified yet effective designs have been implemented. A huge amount of work has been spent tweaking aerofoil angles and analysing airflows over the vehicle to ensure each component is as effective as possible, and this simplified approach has allowed the aerodynamics department to work towards the ‘Aero on a budget’ award at Formula Student Silverstone, with the front wing, sidepods, rear wing, nose cone, bodywork, and floor diffuser all aiming to be manufactured for under £1800. With materials beginning to be delivered, it’s time to get our hands dirty and get building ready for the new HARE-19 vehicle.”
Charlie is the Aerodynamics and Bodywork Team leader. Currently studying for his Automotive and Motorsport Engineering MEng, he is responsible for the design of the aero package, the manufacture of the bodywork, and composite material elements of the vehicle build.
Rafael is an exchange student from Brazil studying at the University of Hudderfield for 6 months as he works towards his Mechanical Engineering MEng. Rafael is reponsible for designing the front wing, nose and the rear wing using CAD and CFD analysis.
