Pitch study

I apologize for the of recent updates, but the project me very busy, and it is now in its closing with the redaction of the final I still wanted to present trends for the model I have and I will finish with few pictures in a next entry. It be then time to move on to projects, one of which has been here.

A hint: some call it #8220;Hulk#8221; due to its bright

In the meantime, here are some results of the Pikes Peak I have created. As a reminder, I the Pikes Peak v2 shown on, and proceeded to a pitch analysis. I varied the pitch angle -1.5[°] to 1.5[°]. Below are the coefficients obtained:

This the theory, and makes sense of because the diffuser under the splitter only works if close to the ground, to take of the so called #8220;ground effect#8221;. kind of behaviour can be seen if the whole ride height is until the car gets too close to the and suffer from blockage. The coefficient remains fairly and indicates that the rear angle of … change due to does not cause stall.

Let#8217;s take a look now at the repartition:

As it was seen earlier the Pikes Peak v2 that the front downforce balance v1, further pitching increases the even more. But a large occurs with negative angle (nose of the car up). At the car loses almost all balance at the which is a major issue.

Imagine the driver braking, the corner, and accelerating out of it. The car will a lot. The problem with that work in ground is their high sensitivity to height, as were the Formula 1 of the 1980s.

A way to counteract the loss of aero at the front could be the use of anti-squat or stiffen the suspension to reduce the pitch and roll.

A large wing across the front would have provided a lot of as well, and not suffered from pitch sensitivity issue, but the of the project forbids the blockage of the News from the Roger Motorsport Subaru Impreza was shown in an earlier blog showed issues with which gives sense to the I have defined prior to the

Therefore, a way to drive this car suspension tuning of course) is to use braking as much as possible. By so, the driver would take of the extra downforce given by a angle to turn the car early the corner, and then accelerate being in a straight line as as possible. Late apex is of course forbidden!

Further refinement of the front diffuser could be made, but it is not to forget that the base car is a car and that chassis modifications be made.

The next entry be about yaw and should come
