Esteban Gutiérrez has qualified 10th for the 2016 Italian Grand Prix. He is the first driver to take a Haas F1 car into the third qualifying round for any race.
The team rolled out a special wing for the Italian Grand Prix. The leading edge of the wing is shaped in the form of a “W”.
Mercedes is utilizing a wing with a leading edge shaped like an elongated V. But the Haas design doubles this form factor in a waving fashion. Visually the two wings look different from the standard flat plank the Haas team and most others run. But what is the advantage of the wave in the wing? How does this help the car go faster? Does it provide more or less downforce then a standard wing? These are the many questions I was asking, and not a single NBC analyst dared to tackle the design impact, including Steve Matchette. I was disappointed.
The new wing on the Haas F1 car has two intended purposes; greater downforce and better stability in high speed turns. Down force is not the only application of Bernoulli’s principle at work here, and not what Haas and AMG Mercedes are chasing with their designs.
Building curves into the wing effectively makes it longer. Just as a shoe lace looks shorter while in the package, it stretches out when you unwind it. In the same way both Haas and Mercedes have done this. Adding a second wing is an alternate approach to lengthening the wing. So why the wave? Wouldn’t a wave increase the drag? Well yes is does to an extent. And it creates vertical down force. But the teams are chasing another aeronautical dynamic, the vertical component of lift.
The vertical component of lift is what allows air planes to turn. Ailerons on the wings is how the pilot controls this force, along with their rudder and elevator. As the pilot turns his wheel to the left, the aileron on the right drops down, which causes the wing to go up. The lift which raises the plane can be directed sideways and cause the plane to turn. To assist in turning an airplane, some wings are not flat but have an upward bend built into it, or dihedral. Remember that a race car wing is like an airplane wing, but upside down . So the AMG Mercedes uses a single bend inverted design or dihedral. The Haas wing has 2 bends on each side, polyhedral.
So as the Haas and AMG Mercedes cars are driving in a straight line there are downward forces coming off of the wing, perpendicular to the wing surface. The AMG Mercedes wing spreads it’s down force in the shape of an umbrella. The downward forces on the Haas wing spread in an even more lateral or sideways direction. As the car enters a turn the down forces on the back of the car will become asymmetrical. The vertical component of lift can be used to help get the car around the corner. I suspect that these aerodynamics are only beneficial at high speeds. So at a track with high speed turns, like Monza, the benefits can be realized. On a slower track the beneficial vertical down force may be negligible and drag inducing. It would require a conversation with the design team to fully understand the aerodynamic nuances… wouldn’t that be cool! I digress…
So the new Haas wing is exciting. The car is faster and lookes very stable…
From the beginning I’ve been touting the reliability of the Haas Team… reliability… race craft… over and over. Well today Esteban Gutierrez essentially addressed my point in an interview with Will Buxton, and i paraphrase, ” since we’ve been consistent we’ve then been able to focus on things that will help us”. The reliability s paying off. After all of those 11th place finishes, he has broken into the top 10.
Grosjean qualified 12th but will start 17th due to a 5 place penalty for his transmission swap. Yes I call it a transmission, not a gearbox. My 5 speed Honda Accord has a gearbox!
Again it comes down to the start. Esteban and Romain have both had good starts and escaped turn 1 unscathed. Let’s believe the same is going to happen. Dare I say they could have not one but two cars in points? I believe Esteban Gutierrez will score his first points for Haas F1. And if Grosjean can manage his tires, I believe he can move up. Points are not out of the question for both drivers. The car’s were especially fast in qualifying. The Team did not post a time for Gutierrez until the very end of Q3, which concerned me. But I believe they were conceding the effort. P10 puts him on the outside of the track and a safer vantage point into turn 1. It was a safe play…
Can the team maintain it’s advantage throughout the race? Have the Haas cars improved? It sure looks like it. A single mistake by a competitor could make the difference. The Haas Team has not made any significant mistakes on race day. This is going to be an exciting and fast race.
Go Haas F1 Team!!!!
It’s Monza… and the Americans are in the house!!!
