I don't mean to hate... But your wing is completely separated. Normally a double element wing in closed configuration should produce a c_L of at least -4 with a c_D of not more than 0.1
typically such a car already has a hydraulic system working elsewhere, it's easier and cheaper to install an actuator which you can plug into the central system. it's why koenigsegg found it lighter to make those fancy doors they have. also actuators don't use energy to hold position so even without the weight gain, it's a far simpler and reliable system to make. not to mention the forces it can generate are much higher than a similar weighted motor setup.

When i grew up racing formula cars in the 1960's and 1970's (which had dual element wings like this one in the video), the FIA banned all "movable aerodynamic devices" because they were "too dangerous". Now, the FIA mandates, controls and issues movable aerodynamic devices with their DRS, creating a "cheater" way for the following car to pass....what an 'effen joke.

The angle seems extremely low to be THAT separated at 35m/s freestream also. I would question the CFD parameters here.
Why it looks like both the configuration have the serious flow separation?
Because is for show and no go.
I want to do my own drs carbon spoiler now it inspired me
What made you choose an actuator in lieu of something like a stepper motor?

@@gaerootthats a penumatic actuator
What kind of part controlling the drs named?
Dude made his own Drs
😅
You mounted rear wing from the lower side? Before active aerodynamics, you should ve get that sorted out.
more popular for FSAE it depends on many many factors
Hi I’m ready interested to know what mechanism of the wing if you happy to share your knowledge
What is the name of the actuator?
Why not use stepper motors instead of pneumatic actuators? Not enough power?

What program do you use for the drag coefficient etc???
A computer-aided design (CAD) program can used to perform that type of analysis -- it's computation fluid dynamics (CFD).
what's that song resp. track?
Hi guys , which software did u use to calculate drag coefficient and lift coefficient
I was thinking same but fuck i study management :=)
I use ANSYS
Nice video. I would request you to explain its mechanism in the next video.

formula student allows for active ground effects while fsae does not, from my understanding of t.7.1.2 and t.7.1.3, this is still allowed
This will run but produce more drag and causing more unstable during high speeds, work of a noobs..!
Wow, such criticism coming from a CAD jockey.
