Scott Dixon served as the test driver in INDYCAR’s simulation of the proposed Aeroscreen that will greatly enhance driver cockpit protection in the future. Dixon, a five-time NTT IndyCar Series champion and winner of 45 IndyCar races, tested a prototype manufactured by Roush Tuesday morning at the Dallara simulator in Speedway, Indiana.

The latest test comes just six weeks after INDYCAR announced a partnership with Red Bull Advance Technologies to design an Aeroscreen concept to protect drivers in the cockpit of their Indy car.

The simulator test allowed Dixon to provide feedback on entering and exiting the cockpit in addition to discuss the sight lines that will come from the framework of the Aeroscreen structure. The design of the Aeroscreen will enclose the cockpit but will be open on top. It consists of a ballistic Aeroscreen anchored by titanium framework.

Dixon’s test on Tuesday utilized the framework produced by Roush as the clear screen itself remains under development. The framework mounts in three areas around the cocking including the chassis centerline, two-rear side mounts and roll hoop integration – to provide enhanced load-bearing capabilities.

“It went pretty smoothly,” Dixon said on Tuesday. “This process has been ongoing, whether it’s the device we’re currently running to looking at the halo systems to the Aeroscreen to this partnership with PPG Aerospace and now Red Bull Technologies.

“It’s evolving. To actually have a piece we can use visually. The additions on this are some areas for cooling and the anti-fog system. We are just making sure the line of site isn’t impeded by any of these. It’s much like the current car with the AFP device. We are actually looking a bit higher out of the car.”

Dixon went through simulation programs that included running at the Indianapolis Motor Speedway, Barber Motorsports Park, Long Beach and Iowa Speedway.

An additional vane has been added to the outside of the screen to help the tipping point of the car after it hits the wall.

Although it is not the full construction piece, it gave Dixon an idea of extraction from the car.

“The extraction doesn’t seem to be any different than the halo,” Dixon said. “That was pretty easy. Visually, there is always the worry about not being able to see the flag stands, but it was actually almost the same as the AFP that we are currently running.

“It didn’t really impede my vision.

“I think the next step is to run the proper one, which I think is down the road in September on track.”

The Red Bull Advanced Technologies design will consist of a polycarbonate laminated screen that includes an anti-reflective coating on the interior of the screen, an anti-fogging device through an integral heating element and possibly tear-offs, all of which will be produced by integrated third-party companies. Another feature for the drivers will be a cockpit cooling option that will be designed by Dallara in conjunction with Red Bull Advanced Technologies.

The Aeroscreen is scheduled to be implemented for the 2020 NTT IndyCar Series season.

“The biggest concern, and it’s a bit of a myth about people talking about the halo and it not being useful for the Indy car because of line of site on the ovals,” Dixon said. “This design doesn’t impede that. What we have run in the past with the windscreen and how we run the angles and how it applies to the frame, there have been no issues previously. There will be an anti-fog system, as well, and that will help.

“Distortion and visual are the biggest things a driver looks at to make sure it doesn’t impede your vision or missing the flagstand. Those were all ticked off the list and there were no issues there.”

Dixon told NBC Sports.com the simulator was able to calculate the visual aspect of the actual clear Windscreen that will be mounted on the framework.

“I’m not sure which material they are going to go with, but there was no actual screen on there, but the additional pieces that will be added for the defog system was added,” Dixon said. “We’ll find out more about that on-track.

“I think it will visually be almost exactly the same as what we have. The AFP is pretty high, so it is exactly where the line of site currently is. The new system is the same in terms of thickness. Getting in the car is the only difference you will notice, but once you are belted in, visually, it will be about the same.”

Aerodynamic figures and center of gravity tests were also simulated during the test because the weight distribution of the car will change. Dixon expects more aero drag with the screen.

He also said the test included running with wheels missing, as well as crash and roll scenarios.

“It was a pretty in-depth test,” Dixon said. “They want to cover most of the bases before we run a lot of tests in the off-season to make sure we have looked at all scenarios.”

Actual on-track testing will be next later this year. INDYCAR intends to have the Aeroscreen on all cars for the 2020 NTT IndyCar Series season.

The addition of the Aeroscreen should dramatically protect the driver, but it won’t change a racer’s attitude.

“This will protect the driver’s head a lot more, but the impacts are still going to be the same,” Dixon said. “We, as drivers, don’t really think about that.

“We think about going as fast as possible.”

Supercross 2023: Results and points after Houston

0 Comments

Eli Tomac led all 23 laps of the Monster Energy Supercross race at NRG Stadium in Houston, Texas and the results show he now has three wins in the season and is one shy of tying Ricky Carmichael’s 48 for third on the all-time list. With this win, he takes a seven point lead in the standings with 12 rounds remaining.

For Tomac at Houston, it was literally a tale of two races. Both his heat and the main started the same with Tomac grabbing the holeshot, but he was passed quickly by Chase Sexton in the heat. Tomac faded quickly after getting passed and was trailing by almost eight seconds at the checkered flag, which caused him to retreat to the hauler and reassess his lines. Without making any adjustments to the bike, Tomac entered the Main with a new attitude, and simply rode better.

Sexton had so great a lead in his heat that one could not even use the cliche that he left Tomac in his dust. By the time the rider with the No. 1 plate crossed the same real estate as the No. 23, the dust was well settled. Sexton had a modest start on the initial gate drop and ended Lap 1 in fourth. He worked his way past Aaron Plessinger on Lap 3 and got around Jason Anderson three laps later. Sexton was able to catch Tomac and pressure him, but he picked a safe, i.e. slow line through the sand section and could never get alongside his rival.

After starting the season with back-to-back seventh-place finishes, Anderson now has a pair of podiums. He won his heat and was easily one of the top three riders in the field, ultimately finishing behind the riders who finished 1-2 in the other preliminary. Anderson was subdued on the podium – happy he was there, but disappointed he has not yet found a way around the riders he is chasing in the points.

In the early stages of the race, Plessinger appeared to have a bike capable of winning. He pressured Tomac on the first two laps and was setting up the pass just as a red flag waved for an injury to Dylan Ferrandis that brought out a red flag. He lost second to Anderson on the restart and eventually slipped to fourth to score his first top-five of the season.

Cooper Webb rounded out the top five. Along with Sexton, he is now one of just two riders with a sweep of that mark in 2023, but with Tomac’s three wins, he is beginning to slip in the points. Webb sits third in the standings, 12 points behind the leader.

Ken Roczen entered the race as the third rider with a sweep of the top five and progressively better results in the first three races of 2023. Had the pattern held, he would have finished at least second, but he struggled for most of the night, finishing fifth in his heat and eighth in the Main. There may have been extenuating circumstances, however. Ferrandis’ injury was suffered when he landed on the back of Roczen’s bike and potentially damaged the No. 94 Suzuki.

The 250 East division made their 2023 debut in Houston, but the name atop the board was familiar. Hunter Lawrence joined his brother Jett Lawrence as the early points’ leader in their respective divisions, but it didn’t come without a little anxiety.

Riding behind Supercross newbie Tom Vialle on the second lap, Lawrence was forced to take evasive action when the leader pitched his bike sideways to scrub speed over a jump. Lawrence veered left and landed off course, but he cleared the Tuff Blox and kept his bike straight. Lawrence made the pass for the lead on Lap 18 and never relinquished it.

England’s Max Anstie made the move from 450s to 250s this year after scoring a best result of 11th on the big bike at Anaheim 2 last year. It didn’t take anytime at all to find the front for Anstie, who finished second in both his heat and main.

It has been a while since Jordon Smith stood on the podium: February 23, 2019 to be exact when he finished that well in Detroit. A series of injuries kept him off the bike for much of 2020 and 2021, but he’s proving to be a factor when he’s healthy.

There was a lot of hype surrounding the debut of Haiden Deegan in the 250 class and he proved it was merited. He finished fourth in his heat and main. He was as far down as ninth at one point in the feature before slowly picking off riders on his way to the front.

Jeremy Martin finished fifth and now has a streak of three consecutive top-fives to his credit stretching back to last year. Unfortunately, his pair of strong runs in 2022 were interrupted by injury.

Making impressive debuts in the 250 division, Vialle recovered from a fall to finish seventh, Chance Hymas finished eighth, and Talon Hawkins just missed the top 10 with an 11th.
