From what I could see,  the other tire was peeled off the rim from going sideways. It was heavily damaged. There were many photos taken of the track and tire marks from the point of the blowout to where the car came to rest.

That is a great accomplishment because so much could have gone wrong and she could have crashed big time. The dragster that was blocking the air friction was probably also providing rear thrust due to the vortice effect of the wind blocking fairing. So it is not so much as a great bicycling feat as it was precision riding and great engineering of the bicycle and dragster.

I know she's not thrust powered, but she is the fastest on a bicycle while riding behind another vehicle to break the wind drag. https://www.bicycling.com/news/a23281242/denise-mueller-korenek-breaks-bicycle-speed-record/

The top speed for a human-powered bicycle without any vehicle assistance is 89.6 mph, set on a recumbent bicycle fully enclosed by a bullet-shaped fairing. For a traditional upright bicycle without any aerodynamic assistance, the closest analogue to Mueller-Korenek's record is probably the 200-meter track time trial, which the current world record holder completed at a speed of about 48 mph.

  I wonder if they might have had a little bit too much downforce on the rear tires.  How did the other rear tire look?  I know the technology exists to measure the downforce in real time but I don't imagine that it is cheap (think Formula 1).  I wonder if anyone looked at the tire tracks just before the accident scene to examine the tire plant?
  Anyway, it was a beautiful car, looked great, sounded awesome and I hope they can fix-er-up!

Hi Mike.  The weather fiasco was not anticipated when I left Bonneville to go back east.  It is quite an adventure. 

Actually Stan, I was sucked.

The tunnel was operated by Geoff Eaker, the son of the firm's founder, Gary Eaker.  The streamlining has as close to a NACA shape as I could get and it provides plenty of clearance around the sides of the engine for future turbos, intercoolers, supercharger, etc, I explained to Geoff.

The first trial established a baseline to compare against during the future tests.  The tufts were analyzed along with a smoke test.  I looked through the center of the windshield like I do at Bonneville, with some clearance between my chest and the top of the tank.  About half to 3/4 of my helmet sticks out above the windshield.  Aero drag coefficient was 0.494.

I asked Geoff about the shape of the streamlining.  He said it is OK, except the top of the tail should be higher behind my butt.  It was higher until this year and I had to lower it 'cause of a rule change, I told him.

My plan is to get rid of those Stegosaurus plates and smooth out the finish, I said.  He said it works just great like it is and that effort is not needed.  Later this was discussed with Gary, too.  He said the plate and rivet texture is OK and gave me some sort of scientific explanation I could not comprehend.

Conclusion:  Do not monkey with the shape and leave the riveted plates as is.

I was going to cut aluminum from the top of the fairing and lower the windshield to reduce frontal area, I told Geoff.  The windshield is far more streamlined than me, he said, and it is best to leave it like it is.  Geoff said I need to lower my head.  My chest was on the tank and I just peeked at the horizon through the lowest part of the windshield for another trial.  Aero drag coefficient dropped down to 0.457.  My chest was on the tank for the next trials.

Conclusion:  Keep head down and behind windshield.  Tomorrow or the next day I will post something about the other trials.

...Until the pumping project really moves forward with positive salt lay down, we won't see any high speed FIA records set at Bonneville.

Well said  cheers and hope that happens,

Sumner

glad to read your assessment of Flash Point---there may be a reason why Speed Demon uses so many tires  soerta like "1 Run"
