After setting it apart in Austria to additional refine the idea, McLaren has lastly debuted its model of the pivoting Method 1 rear wing. It’s an experimental prototype meant primarily for knowledge assortment, with the ultimate model anticipated to reach within the second half of the season. However McLaren’s thought for the pivoting wing is much extra complicated than it’d initially seem.
Curiously, whereas Ferrari’s pivoting wing and Pink Bull’s model share just about nothing in frequent – neither the course of rotation nor the best way the motion is achieved – McLaren’s resolution seems to borrow sure rules from each, earlier than distinguishing itself by way of its personal extremely refined and complicated engineering decisions.
The engineers on the Woking-based crew determined to not combine the actuator into the endplate, as Ferrari has achieved with its so-called “Macarena” wing. As an alternative, they retained a centrally mounted actuator that, by way of an ingenious three-link mechanism, permits each flaps to rotate into the deployed place.

In essence, the wing rotates backwards because it pivots open, very like the Pink Bull RB22 design. Nonetheless, McLaren’s engineers made a very fascinating alternative: they don’t elevate the outer fringe of the wing when it opens. This helps scale back the turbulence generated when the outer corners turn into uncovered, in contrast to Pink Bull’s resolution, which makes use of a fancy system of lateral pivots that themselves rotate throughout deployment.
On the McLaren, the lateral pivot factors are extra standard. Two free-moving pivot parts are positioned on the ends of the higher flap, permitting the movable wing parts to rotate whereas following the motion of the hydraulic actuator. This design retains the wing suggestions very near the endplates, limiting the formation of turbulence that may usually improve when the outer sections of the wing are uncovered.
Much more fascinating, nevertheless, is the design of McLaren’s central actuator. Whereas Pink Bull makes use of a sturdy metallic construction housing the actuator and connecting on to the rotating pivot that raises the wing, McLaren’s engineers have adopted a wholly completely different method: three interconnected hyperlinks joined by pivot pins that enable them to tilt and rotate freely. It’s a refined resolution that achieves the specified movement by way of a much more intricate kinematic association.

When the movable wing is activated, the primary hyperlink (proven in blue within the photographs above) is pushed by a piston extending from the actuator till it reaches an angle of roughly 45 levels. The second hyperlink (proven in white) strikes accordingly, extending into an nearly horizontal place. Lastly, the third hyperlink (proven in yellow), which is linked to the decrease of the 2 movable flaps, rotates upwards till it types an angle near 90 levels with the second hyperlink.
In abstract, the ultimate yellow hyperlink is the element that bodily lifts and helps the flaps, ending up in a vertical place. With this association, the pivot factors should not hooked up to a hard and fast assist construction as they’re on the Pink Bull – which required the development of a inflexible “cage” to accommodate the mechanism. As an alternative, the hyperlinks themselves function the load-bearing construction, possible providing a weight-saving benefit as nicely. It’s a extremely intricate but exceptionally intelligent engineering resolution.
