Question about the front wing's flaps !

Post

hello guys,
hope you all doing great,
i would like please to know info about the flaps which is :
1- how many degrees the flaps move ? is it 6 degrees up ?
2- what is the standard degree between the cord and the main plane ?
3- where is the servo motor that is used to make the flap changes degrees, placed ? is it in the nose ?

if you have any technical pictures that shows the mechanism would you please send it
thanks in advance :)

There arent any servo motor to make flap changes on current cars. It was dropped before the 2011 season with the introduction of DRS.

ah you mean the front wing is static !?

i was checking how the drs work well it's a hydraulic system and not servo mechanism ! damn it !

technically both front and rear wings do have flaps of the slot type .
sure you could make the adjustment hydraulically or vía servomotors but the question is if the extra weight and complication is a net advantage .
The DRS is a completely separate functionality altogether as it usually lifts the leading edge of the flap up so to not only reduce angle of attack but also effective chord length and cross-section creating a whole new wing at the rear - no wonder teams have found out the transition between DRS deployed and closed is mechanically quicker done than airflow is sorting itself out .so a swift mechanism is not really the goal it must be a reliable robust construction. The advantage of using the hydraulic system is the sophistication and quality of parts available and teams have a lot of experience and expertise in this field (gearbox and suspension ) whereas minature electric drives are not really available off the shelf in a quality necessary for the harsh environment of formula 1 ..(think about it:brushless motor needs a brain and power electronics to be driven...then you need a lot of cables as well...it seems unlikely you can save a lot of weight with that approach give´n you have the hydraulic power alread on board and a minature servovalve and piston and a positionsensor could do the job .

thanks for the info but about the servomotor well it's really easy to put it for DRS easier than sophisticated hydraulic system and very less parts to use but ! it's shape won't work to have a very small with less drag shape so they prefer to go with the hydraulic with small parts

but my question was, is the front wing still dynamic or it became static after introducing DRS ? and about front wing if it's a servo should it be in the nose with a cable system ?

The front wing is static ever since DRS has been introduced.

ok and how many degrees is the angle between the horizontal and the cord of the main flapof the front wing ?

well i was reading about the angle of attack but in aircraft so talking about lift, the maximum angle at which maximum lift is generated is 15 degrees but this may vary depending of the airfoil so this means damn it another problem ! lol
