Are modern sport prototypes less likely to takeoff and fly?

[g-force_addict]

If so why less likely to fly? By which design changes?
Or just less likely because most racetracks reduced straight lengths and thus top speeds?

Why mostly 1990s+ prototypes began to fly?

Maybe as they banned/limited venturi tunnels thus mandating flat bottoms with less downforce.

Would Nascar style roof flaps prevent them from going flying?

Are open top prototypes less likely to take off?

The 2005/2006 rule change mandated a highly regulated floor which reduced lift in events of high yaw. Also recent years saw the introduction of large holes in the fender(to reduce pressure build up in the wheel well) and the shark fin(which kills lift under high yaw)

These blow over events are possible to happen at any speed, either due to collision or any other incident. Higher speeds only make these matters worse.

Where would you want to place those? LMP's are quite different from each other, adding such a requirement is impossible without retaining the uniqueness of every LMP

Richard Westbrook escaped injury following a massive accident Tuesday at Daytona International Speedway in TUDOR United SportsCar Championship testing.

The Englishman’s No. 90 Spirit of Daytona Corvette DP suffered an unidentified failure while braking into the high-speed Turn 1 section on the 3.56-mile oval/road course, sending the car airborne and into a series of rolls, according to multiple eyewitness.

Westbrook was treated and released from the infield medical center but could not be reached for comment.

The car sustained considerable damage to all four corners, which has resulted in the Troy Flis-led squad packing after completing just a few hours of testing with its newly upgraded DP.

Sportscar365 will have more on this developing story as it breaks.


Analysis say it happened due to a tyre failure
