The aero updates include a revised and wider engine cover, a modified floor body, floor edge and diffuser, new sidepod inlets, and changes to the mirrors.
Explaining the floor modifications, the Italian team noted that the “forward floor edge changes lower static pressure local to the floor edge and helps draw increased mass flow under the forward floor between the fences,” adding that the “diffuser modifications enhance the strength of the rear floor edge vorticity, giving a local load gain within the diffuser.”
At the rear, the suspension shrouds have been re-profiled, and the brake drum scoop inlets redesigned.
Regarding the latter change, the team says that it “reduces losses incident onto the upper rearward wing cascade, thereby increasing their local load.
The revised scoop exit also allows these wings to generate more load by causing less aerodynamic blockage.”
In addition the suspension shroud changes create “a better interaction with the new rear brake drum geometry, increasing local load generated by the wing elements of the drum assembly.”
Tsunoda is anticipating that a step in performance will be evident over the Singapore weekend.
