From formula1.com: This drawing shows Mercedes clever 'double DRS' system in its entirety. Air is sucked into holes in the rear wing endplates (left inset) which are exposed when the DRS system is activated. Using similar channelling (highlighted in yellow on car profile) - but in reverse - to that utilised two seasons ago for the now-illegal F-duct, the airflow is routed into the beam wing, across the top of the deformable rear crash structure, along the side of the engine and then through the chassis (centre inset) before it exits through the front-wing pillars to blow onto the front-wing flaps (right inset), stalling the wing, cutting drag and boosting top speed. I enlarged the diagram so it's a touch more legible: Image Unavailable, Please Login
All I need is some soft copper tubing, a soldering gun, some zip ties and a drill with a unibit and I think I could make it work.....it won't be pretty, but neither are this years F1 cars. My F1 team has an awesome set of tools (said in the voice of Jeff Spicoli)
http://smibs.tv/the-flying-lap/china-bahrain-2012-f1 Have a look at ~9:00 minutes into the video. The photographer must have had a camera mounted on his shoe to get such a good shot of the underside of the Merc front wing. great stuff. I hate to give Peter Windsor any accolades but his debrief show with Scarbs is always outstanding.
