Ferrari’s “Macarena Wing” – Innovation with a Structural Price 🏎️ But there’s one aspect that hasn’t really been discussed much: the structural side of it. Unlike a traditional DRS system, this flap doesn’t just hinge open slightly — it rotates a full 180°. At around 90°, the flap is effectively presenting its maximum projected frontal area to the airflow. In other words, there’s a sharp spike in drag at very high speed. The structure has to survive that transient peak load, and that’s no small ask. And that’s just part of the story. Mid-rotation, the aero behaviour becomes pretty aggressive. You’re likely looking at: • Strong flow separation • Intense vortex shedding • Significant oscillatory aerodynamic loading • A shedding frequency that keeps shifting as the car slows under braking That last point is the tricky one. As the car decelerates, the freestream velocity drops — which means the characteristic vortex shedding frequency changes continuously. So now you’re trying to avoid structural eigenfrequencies across a moving excitation spectrum. That’s a nightmare from a structural dynamics perspective. The obvious fix? Increase stiffness. But higher stiffness usually means more material. More material means more mass. And that mass is sitting high up at the rear of the car. Raising the centre of gravity has real consequences: • Increased lateral load transfer • Potential changes in cornering balance • Reduced transient stability So while you gain on the straights, there’s almost certainly a cost in the corners. Ferrari switching back to a conventional DRS configuration on the final day of testing might be a subtle hint that they’re still weighing that compromise carefully. My take? We’ll probably see a standard rear wing in Melbourne, and the “Macarena Wing” brought out selectively at true low-drag circuits like Baku or Monza — tracks where straight-line performance is king and any handling trade-off is easier to justify. What do you think — is the straight-line advantage worth the potential compromise in overall balance? #Formula1 #Aerodynamics #CFD #MotorsportEngineering #VehicleDynamics

🏎️💨 From razor-sharp downforce machines to brute-force racers muscling their way through turbulent air, every race vehicle tells a story of how design meets resistance. Formula 1 sits at the top with surgically precise airflow management, using wings, floors, and vortices to generate massive downforce with minimal drag. Close behind, Le Mans Hypercars strike a calculated balance between straight-line efficiency and high-speed stability for endurance racing. GT3 cars work within road-based silhouettes, relying on splitters and wings to maintain grip without extreme aero freedom. MotoGP bikes face a unique challenge altogether, where the rider’s exposed body becomes part of the aerodynamic equation, constantly disrupting airflow at 300+ km/h. At the other end of the spectrum, NASCAR stock cars confront the air head-on, boxy, powerful, and designed to race in packs where drafting matters more than slicing cleanly through the wind. It’s a visual reminder that in motorsport, speed isn’t just about horsepower — it’s about how intelligently you fight the air.

Drama pagi tadi di Cfd jembatan dukuh atas, Kronologi saya bertiga lari tiba-tiba dibelakang ada pesepatu roda rombongan teriak “ permisi2 “ dan sangat keras gak berselang lama runner dibelakang kita marah2 dan mau kejar pesepatu roda tsb ( baju oranye ) dia tidak terima karena di dorong, dan memang berbahaya kalau tiba2 di dorong ketika lari apalagi mereka pesepatu roda speed lumayan. Alhasil marah lah mas2 tsb, kita coba lerai, masih ada rombongan pesepatu roda yg provoke runner/pejalan.Injut 📹 : Treads/rp.nagara Via @jakpus.terkini -follow @jakartapusat.info untuk info seputar Jakpus #jakartapusat.info #CFD #Sudirman #JakartaUpdate #InfoJakpus DukuhAtas

Pemerintah Provinsi (Pemprov) Jakarta masih terus melakukan penataan Jalan Rasuna Said. Rencananya, kawasan itu akan dijadikan tempat pelaksanaan hari bebas kendaraan bermotor (HBKB) atau car free day (CFD). Gubernur Jakarta Pramono Anung mengatakan, pihaknya berencana memulai gerakan pemilihan sampah pada Ahad 10 Mei 2026 di Jalan Rasuna Said. Kegiatan itu akan dilakukan berbarengan dengan pencanangan HUT ke-499 Jakarta. Dengan dijadikannya Jalan Rasuna Said sebagai lokasi CFD, Pramono menyatakan, warga di Jakarta akan lebih memiliki pilihan untuk berolahraga. Namun, ia belum mengumumkan secara detail waktu CFD dapat dilakukan di kawasan Rasuna Said. Reporter: Bayu Adji.

Ferrari’s "Macarena Wing": A masterclass in aero-structural compromise. 8 to 10 km/h of extra top speed is an engineer’s dream. But in F1, you never get something for nothing. The physics of Ferrari’s rotating flap are fascinating and, frankly, a bit of a structural nightmare. Unlike a standard DRS that just cracks open, this flap rotates a full 180°. At the midway point (90°), it presents its maximum projected area to the airflow. That creates a massive, transient spike in drag and load at exactly the moment the car is at its fastest. The structure doesn't just have to be light, it has to survive that peak. Then there is the fluid dynamics of the transition itself. Mid-rotation, you aren't just losing downforce you’re dealing with: - Massive flow separation. - Intense, chaotic vortex shedding. - High-frequency oscillatory loading. As the car slows down, the shedding frequency shifts. This means your "excitation spectrum" is constantly moving, hunting for the structural natural frequency of the wing assembly. If they hit resonance, the wing doesn't just vibrate, it fails. The easiest fix is to add stiffness, but stiffness equals mass. And mass sitting that high and that far back is the enemy of lap time. It raises the center of gravity, worsens lateral load transfer, and makes the car feel "lazy" in high-speed transitions. Ferrari went back to a standard wing on the final day of testing. That tells me about the trade-off between straight-line gain and cornering balance isn't settled yet. It’s a "specialist" tool for Baku or Monza where the drag reduction outweighs the handling penalty. Aerodynamics never lives in a vacuum. Every aero gain has a structural price tag. If you ignore the aero-elasticity or the CG shift, your "fast" wing might actually make the car slower over a full lap.

Ferrari’s “Macarena Wing" One angle that hasn’t been explored enough is the structural challenge behind this concept. Unlike a conventional DRS, this mechanism doesn’t just slightly open — it rotates nearly 180°, making it far more demanding structurally. Around the 90° position, the flap sees its maximum projected frontal area, causing a sharp drag spike at high speed — meaning the structure must endure a sudden and extreme load case. And that’s only one part of the problem. During mid-rotation, the aerodynamic behaviour turns highly unstable, involving: Strong flow separation Intense vortex shedding Fluctuating aerodynamic forces Continuously varying shedding frequency as speed drops The real complication lies in this changing frequency. As the car decelerates, airflow velocity reduces, which means the excitation frequency keeps shifting, making it difficult to avoid resonance with the structure’s natural frequencies. From a structural dynamics standpoint, this becomes a highly complex and critical design problem. A straightforward solution would be to increase stiffness, but that comes with trade-offs: More stiffness → more material More material → higher mass Added mass positioned high at the rear This shift in mass distribution directly impacts vehicle dynamics: Higher centre of gravity Increased lateral load transfer Possible changes in cornering behaviour Reduced agility during transient manoeuvres So while straight-line performance improves, there’s likely a compromise in handling performance. Ferrari reverting to a traditional DRS setup during final testing could indicate that this trade-off is still under evaluation. My perspective: A standard rear wing is likely for most circuits The rotating concept may appear selectively at low-drag tracks like Monza or Baku, where straight-line gains outweigh handling compromises What’s your take — would you trade overall balance for straight-line advantage? #Formula1 #Aerodynamics #CFD #MotorsportEngineering #VehicleDynamics
