After more than two years of testing and development, IndyCar is preparing for the first on-track test of its windscreen prototype Thursday at ISM Raceway near Phoenix. The test will coincide with the Verizon IndyCar Series' preseason open test next week at the raceway.

The windscreen will be affixed to the car of four-time IndyCar champion and Chip Ganassi Racing star Scott Dixon. In a news release, IndyCar said the primary goal of the test will be to "validate visual acuity for the driver in various lighting conditions – under full sun, at dusk and at night under track lighting."

The test is scheduled for 3-7 p.m. ET.

The windscreen is made of proprietary Opticor advanced transparency material by PPG, the same material the company uses in its production of fighter jet canopies. According to IndyCar's director of engineering and safety Jeff Horton, who has led the development of the windscreen along with IndyCar medical consultant Dr. Terry Trammell, the "material has shown to be stronger, lighter and more impact-resistant than polycarbonate previously used."


The prototype windscreen already has undergone numerous tests in the wind tunnel and racing simulator at Dallara, but as IndyCar President of Competition Jay Frye is fond of saying, "(Testing) doesn't drive."

"The wind tunnel says this or that, well, that’s not exactly driving the car," Frye told IndyStar recently. "Once we get it on a car, we’ll see how it affects vision and the handling of the car.

"We’ll try to do a back-to-back type of thing. We'll run a car in morning with a windscreen then a little later without it, and you can collect the data and see how it affected the car. That will make it better and better."


The most basic goal of a windscreen, of course, is to enhance driver safety without negatively affecting the driver's vision or the performance and look of the car. Frye and his team also have to consider the different venues IndyCar visits and all the variables that come with them, including lighting conditions, aerodynamics and heat.

"Any piece we put on an Indy car must work for multiple types of venues and different lighting conditions," Frye said. "It has to be versatile.”

Frye has made it clear that despite the upcoming test, there is no timetable for implementation of the windscreen. In fact, there's not even a guarantee it will be implemented. He simply wants to learn all he can from testing before making any decisions about the future of the windscreen.

While hardly anything is unanimous in the world of motor sports, Frye's windscreen is expected to have plenty of support of the paddock. Since development began, many have encouraged IndyCar to explore any and all measures that enhance driver safety.

"A couple years ago at Indy, a mirror came off a car and just missed Graham’s (Rahal) head and dented the rear suspension," Bobby Rahal, Graham's father and Rahal Letterman Lanigan Racing co-owner, told IndyStar. "And that’s just a mirror. You can imagine what something heavier than that will do. So anything you can do to make it better, safer, why not?"

Graham Rahal also is a proponent of the screen. Though he is particularly wary of the potential visual impairments or distortions it could cause, he applauded IndyCar's efforts to enhance driver safety. He said he has faith that much like with the 2018 IndyCar, Frye and his team will deliver something everyone can be happy with and proud of.

"I think IndyCar is doing it the right way, having a glass screen," Graham Rahal said. "I think that’s the right way to do it versus the halo or others. There’s a lot of aspects that go into this, so we got to make sure that all sorts of those things work as well, but I’m excited for it."

This probably isn't the exact 'right' time / or way to mention this but here goes:


I've often wondered why NASCAR, Drag Racers (several different classes) are all covered where the drivers sits - and the Indy Cars are much more closer to the ground to
enclose the bottom of the cars without much of a "bubble" over the driver. They all seem pretty concerned about breaking the "wind-barrier" by spending oodles of time in
wind tunnels on their designs ... /think /think /think

I can remember when "Big Daddy" Don Garlits first showed up with a big canopy-like cover at the "U. S. Nationals" drag races. It seemed like the more trips down the strip,
the faster he got. It wasn't long afterward that more and more racers had a canopy to help break the barriers to get more speed down that 1/4 strip ... :) :) :)

Y'all know I'm not an Indy Car designer ~ But I always wondered if some type of "larger-canopy-type design" would help the drivers get more speed. I'm pretty sure they've
spent multiple hours in wind tunnels; Maybe just maybe not quite enough on a canopy related issue ... /facepalm /facepalm /facepalm

Just talkin' out loud & most likely completely out of turn ... /doh /doh /doh

Later,

Steve

Steve, the windscreens for both IndyCar and F-1 cars are more for safety then for gaining more speed. Although if more speed resulted.... But it's mainly for safety and if the cars gained more speed then they'd have to combat the issue of the cars flying when hit. And that rarely ends up good with IndyCars (or F-1)
