McLaren has unveiled its 2019 Formula One race car, named MCL34. As with the 2018 car, the covers were taken off at the McLaren Technology Centre in Woking, UK.
Were those grooves along the top of the boomerang wing present in Barcelona?
They were added through the test, can't remember which day. What I didn't notice until that picture was how the grooves mirror the vane pattern underneath. Not too sure of the exact benefit of it, but the grooves would generate small vortices to prevent flow separation and reduce drag. It must somehow marry with the work being done by the vanes along the bottom.
CMIIW the groove on the boomerang was there for legality reason, not because aero reason. because no bodywork should appear if the car viewed from the bottom. so if there's a slit on the floor, there's a slit on the bodywork perpendicular above it.Xero wrote: ↑14 Mar 2019, 14:43They were added through the test, can't remember which day.

It has to as per the regulations... That’s why you see those grooves in all of the other cars in surfaces that are on top of the floors.Xero wrote:They were added through the test, can't remember which day.

Correct! It's called the silhouette rule.pisangkacau wrote: ↑14 Mar 2019, 14:55CMIIW the groove on the boomerang was there for legality reason, not because aero reason. because no bodywork should appear if the car viewed from the bottom. so if there's a slit on the floor, there's a slit on the bodywork perpendicular above it.Xero wrote: ↑14 Mar 2019, 14:43They were added through the test, can't remember which day.

No, they're for legality, which is why they match the slots below on all cars.Xero wrote: ↑14 Mar 2019, 14:43They were added through the test, can't remember which day.
