A new year brings a new challenge, this year the MVRC has continued from last year with only slight changes to the rule book.
Last year the Mercury Motorsport car showed potential and went through many major changes and in the end came 6th over all in the challenge.
This year the goal is to improve even if it only means 5th outright at the end of the season. This year the challenge has expanded with the intro class of cars who may also be occupying the mid-field just to make things harder. The design of this year’s car has been simplified with the focus on cooling and making sure we have the required 3m^3/s through the heat exchangers.
Many CFD tests have been run on the car with the sole purpose of improving the cooling. Some of the results are shown below in order.
(figures below are for half the car only and need to be doubled)
As can be seen from the results initial flow was not enough and was being impeded by the initial design of the front of the car. while redesigning the front of the car the top elements of the front wing were removed and we say a massive jump in the number to 1.16 m^3/s, work then began on the main plane of the front wing developing an airfoil shape that actually directed air from under the wing up and towards the cooling intakes. at its peak we can see we got the cooling flow up to 1.83 m^3/s well above the requirements, development then began on the additional flaps of the front wing to aid in the downforce department and suspension cover to meet the rule book requirement, unfortunately, this had a negative impact on the cooling flow bringing it down to half our peak production. in the final test we implemented a wider opening at the front of the car for the front wing with the hope of driving more air under the wing and in to the cooling ducts, this solution has had the effect we were after and we hope our results match the official testing as this is what we have submitted for the first round.
