Could the renewed trend under the 2022 regulations of teams to enhance their rear wing performance with exhaust and wastegate gases be a contributory reason for the spins of Charles Leclerc in France and Max Verstappen in Hungary? F1.com technical expert Mark Hughes investigates...An often-overlooked part of an F1 car’s aerodynamics is the interplay between diffuser, beam wing, exhaust and wastegate exits. Some years ago, when the beam wing had been banned, teams were finding big compensating performance gains by directing the exhaust flow to the underside of the rear wing. This would have the additional effect of pulling the airflow around it in that direction too.

The FIA then stepped in and stipulated a longer exhaust outlet relative to the rear wing and a maximum angle for the exhaust outlet pipe, so reducing the effect. 2022 Hungarian Grand Prix: Max Verstappen recovers neat 360-degree spin Those restrictions are still there in the current regulations introduced this year but now the beam wing is back, and so it has become possible once more even within those exhaust restrictions to get an enhanced aero effect from the exhaust. The drawings below use the Red Bull’s arrangement of exhaust, beam wing, wastegate and diffuser as an example. With the exhaust angled upwards by the maximum permitted, even though its exit is almost level with the lower element of the beam wing, there will likely still be a powerful effect, pulling the airflow up towards the underside of the main wing. www.formula1.com/en/latest/article.tech-tuesday-could-this-2022-f1-design-trend-explain-those-strange-spins-for.6JxcwW1qoLJAwY7uxjveRZ.html
