With the lauch of the new Ferrari i remembered seeing this, one of the place where there is more freedom in 2021 is the engine cover if a understand corretly. So is the 2021 rules allowing some sort of "horns" like the Ferrari ones ?
Errr... as I read it, no. There is more freedom for the 2021 upper surfaces than the 2021 floor and wings, not that there is more freedom for the upper surfaces than in 2020. The bodywork between 20 and 150mm behind the face rear of the cockpit opening (Xc) has to be at least 50mm thick (i.e. 2x 25mm radii), the only exception is around the aperture for the air intake where there isn't a specified radius.
3.7.3 Engine Cover
Bodywork declared as “Engine Cover” must:
a. Lie within RV-RBW-EC.
b. Be arranged such that when viewed from the side, no part of RS-RBW-EC may be visible, with the exception of the opening described in Article 12.4.1.
3.7.4 Coke Panel and Engine Cover Shape
On each side of the car, the combined external Coke Panel and Engine Cover surfaces must:
a. On any X section, form one tangent continuous curve. Furthermore:
i. Outboard of Y=25 the radius of curvature of any such section must not be less than 75mm if convex, or 50mm if concave, with the exception of a rectangular region bounded in plan view by (XC=20, 175) and (XC=150,375) where the radius of curvature must not be less than 25mm.
ii. Between Y=5 and Y=25 the radius of curvature of any such section must not be less than 25mm.
b. Not contain any apertures ahead of XR= -55, other than those permitted in Article 3.7.6.
c. Not contain any surface parallel to a X plane ahead of XR= -55.
d. Rearward of XR = -300 and prior to the addition of any apertures, the X component of any normal to the external surface must not be negative.
The cameras (position 3) and mounting brackets defined in Article 8.17.8 will be exempt from the restrictions of this Article.
12.4.1 Principal Roll Structure
The principal structure must be at least at Z=958 at XC=35.
The principal roll structure must have a minimum enclosed structural cross section of 10000mm², in vertical projection, across a horizontal plane at Z=900. The area thus established must not exceed 200mm in length or width and may not be less than 10000mm2 below this point.
The principal structure must pass a static load test details of which may be found in Article 13.7.1. Furthermore, each team must supply detailed calculations, which clearly show that it is capable of withstanding the same load when the longitudinal component is applied in a forward direction.
In order that a car may be lifted quickly in the event of it stopping on the circuit, the principal rollover structure must incorporate an unobstructed opening, whose section measures 60mm x 30mm with internal radii of no more than R15mm, clearly visible in side view, to permit a strap to pass through it.
