Red Bull F1, points expected to evolve in 2023 F1 machine “RB19″[F1-Gate.com]

RacingNews365.com technical analyst Paolo Filisetti analyzed elements from this season’s machine that will be installed in Red Bull F1’s 2023 F1 machine “RB19”.

The Red Bull RB18 has become one of the most dominant cars in F1 history. If a car is clearly dominant, there is an implicit rule that is always respected that the next car is simply its evolution.

The Red Bull RB18 represents arguably the best interpretation of F1’s technical regulations for 2022, as well as being the least affected by the mid-season regulation changes (implementing Technical Directive No 39, which came into effect from the Belgian Grand Prix). It was also a machine.

A defining characteristic of the Red Bull RB18 was its excellent control of the ‘porpassing’ phenomenon that has reappeared in F1 cars this season as a legacy of ground effects. Aerodynamics such as floor geometry, front suspension geometry and visual simplicity allowed the RB18 to manage impact-inducing effects. This effectively neutralized the bouncing that was common in Ferraris and Mercedes.

To simplify the concept, we mechanically approximated the effect of active suspension, which is prohibited in line with current technical regulations.

The RB18’s performance was based on a perfect integration of aerodynamics and vehicle dynamics with the Honda RA622H power unit. The factor that ties the two together is that he was over the 798kg limit at the start of the season, which led to a lighter car.

Under the direct supervision of Adrian Newey, the team of designers led by Pierre Washet quickly intuited that one of the factors capable of producing performance was the controlled management of the midsole stiffness. It was very important that the lateral peripheral section not undergo deformation. This prevented the floor from creating an aerodynamic block at very low ride heights and did not induce destruction of the airflow structure under the car which could increase porpassing.

Throughout 2022, Red Bull Racing focused on weight reduction and gradual updates to the floor. At least 16 versions of the floor were created.

Even on the floor introduced at Silverstone, where there was little positive feedback, the information gathered throughout the season allowed the technical office to lay the groundwork for the RB19 while maintaining the priorities that characterized the development of the RB18. rice field.

At the heart of the RB19 project is the overall weight reduction of the car. Also, the rear lower chassis is shaped to allow for partial housing of the cooling system.

Details of RB19
While maintaining the strong ‘family feel’ of Red Bull’s cars, the RB19 follows two guidelines that characterize its profound redesign. Weight saving was the cornerstone of the project’s original objectives, already starting with the idea of ​​a lighter chassis that was widely discussed over the summer and never actually adopted.

The RB19 monocoque is about 3kg lighter than the previous model. Thanks to the new regulations, the elbow (the part that connects to the venturi channel) is 10mm higher and the side profile in front of the rear wheel is 15mm higher. Suppresses deformation of the periphery.

The arrangement of the gearbox case and suspension elements should be characterized by increasing and narrowing the lower venturi channel section.

In terms of upper aerodynamics, the overall layout of the sidepods is characterized by a revised cutout below the sidepods that creates a ‘double floor’ effect while maintaining strong contact points with the 2022 model year. The sidepods extend to the rear of these cutouts.

Visually, the RB19 is not surprising in terms of geometry, and while the structural solutions and vehicle dynamics of the RB18 are similar, it will be a very big evolution.

RB19 side view
The similarities between the RB19 and its predecessor are striking. Highlighted in the image above is the profile of the channel below the sidepods, becoming more extreme towards the rear.

side pod inlet
The sidepods retain the characteristic shape of a square inlet with a lower lip forming the lower front upper edge of the sidepod channel.

floor
Like the RB18 (see Silverstone evolution diagram), the floor is the cornerstone of the RB19’s aerodynamic concept. The areas of greatest intervention concern the central area following the reduced flexibility allowed by the new regulations and the elbow of the diffuser. Rumor has it that engineers have managed to keep the weight of this element lower than the latest version for 2022.
