Gravel Trap: Did Williams use active aero in Spain?

http://www.racecar-engineering.com/blog ... =hootsuite

...

Buxton’s theory which has reportedly been confirmed by sources within the team is that Williams has lost its way somewhat with the balance and setup of the FW38. The wing package used in Barcelona features adjustable elements front and rear. The movement of these elements was automated, controlled by an onboard computer, the computer was said to be responding to signals from a yaw sensor fitted to the car along with the steer angle, air speed and possibly torque demand.

The idea behind it is that the computer would react to the car if it was understeering or oversteering and adjust the wings elements to accordingly, this would at least in theory allow the Williams engineers to find a balanced aerodynamic setup on the car, once they had found the numbers the wings on the race car could be set or reworked accordingly to suit.

Active front wing was my assumption too, not much else the control arms could be for.

Having an active rear wing plus drs would be redundant though considering Williams weren't really chasing laptimes, the extra wing appears to be quite simple added downforce.

ok we could assume that flaps in front were operated by the jaw. But regarding rear as Buxton said they had adjustable rear. Could that be the reason why they ran this thick DRS actuator and was partially open. Does this thick DRS actuator operates with flaps?

Why are they still lugging the old nose/wing around...
Surely they have spares of the new design by now?

Honestly I think there is only one available for Massa and one for Bottas.
Let's hope they survive Monaco.

They had at least one spare since Felipe broke one at the guard rail.

My idea is that the extra wing will simulate the DF loss when the DRS is fully open. Then they can close DRS flap by incremental amounts to add levels of DF to test the balance. Because the actuator in race probably only has to positions, open and close, this one is a bit larger because it will possibly have the ability to control the angle of the opening of the flap and fine tune the angle of attack.

After running thursday without it, a monkey seat was put in the car in 11th hour.

Williams - Tech analysis

By: Giorgio Piola, Technical Editor
Co-author: Matt Somerfield, Assistant Technical Editor

It's fair to say that Williams is a little adrift of where it would expect to be this season, primarily because of the Red Bull resurgence, however, it has been suffering some of its own issues along the way.

Having set up a wet weather and low-speed working group last season, it is constantly trying to resolve issues it faced in the past. Based on these past discretions, you'd expect them to have struggled significantly on the wet low speed streets of Monaco, but it seems to have made some progress.



In order to change the airflow around the front of the floor and sidepod undercut, a revised layout and geometry of the fins attached to the front brake duct were used.

Meanwhile, in order to mitigate the cooling requirements for the low speed circuit changes were made, adding two slits behind the louvres, allowing more heat to be rejected.



At the rear of the FW38, a new monkey seat was employed to help change the point at which the exhaust plume and surrounding airflow upwashes under the wing, improving stability and increasing downforce.

The monkey seat was reminiscent of the one used on the FW37 but rather than being mounted on the crash structure it was hung from the rear wing support pylon from a central spar, primarily because of the placement of the two wastegate exhausts which run either side of the main exhaust this season.
