Report 2 from Giorgio

From Dr. Giorgio Rizzoni:

Friends of the Buckeye Bullet:
This is the second of a series of daily reports describing the progress of the Buckeye Bullet 2. The BB2 is a hydrogen fuel cell land speed vehicle designed to break the speed record for electric vehicles at the Bonneville Salt Flats in Utah. It is designed and built by Ohio State University students out of the Center for Automotive Research in Columbus, Ohio. More details may be found at:

August 18th – Tech inspection
The technical inspection was completed without any problems.

August 19th – First run!
The team spent a good part of Tuesday taking care of body details, and the Bullet 2 was eventually ready to get in line for the first run. Here is the report from Kevin Ponziani:

We just made our first run on the track of the week, and we got up to about 210mph, and were able to shift up into third gear. At that point the car shut down, likely as a safety measure. We're investigating why it shut down as we speak, and will have some photos up soon.


And here is the late evening report from Don Butler.

THE BB2 MADE THE FIRST RUN AT 5:00 THIS AFTERNOON. THE CAR ACCELERATED QUICKLY AND BETTERED ITS PREVIOUS SPEED THROUGH THE FIRST MILE BY 45 MPH. ROGER SAID THE BB2 SHIFTED SMOOTHLY FROM 1ST TO 2ND WHILE MAINTAINING POWER. THE CAR REACHED 218 MPH WITH AN AVERAGE SPEED OF 210 BEFORE LOSING POWER AS HE APPROACHED MILE 3. THE BB2 SLOWED TO 180 MPH AND THEN ROGER BROUGT IT TO A STOP WITHOUT POPPING THE CHUTES. "THE CHUTES AREN'T VERY EFFECTIVE BELOW 200 MPH, SO I JUST USED THE BRAKES. I DIDN'T WANT THE TEAM TO HAVE TO REPACK THE CHUTES." THE FIRST INDICATION IS THAT THE HELIOX VALVE CLOSED AND THE FUEL CELLS SHUT DOWN. THE TEAM WILL ANALYZE THE DATA THIS EVENING TO CONFIRM THE PROBLEM AND IDENTIFY A SOLUTION. ROGER ALSO NOTED THAT THE GEAR RATIOS ARE ALMOST PERFECT SINCE THERE WAS NO TIRE SLIP DURING THE SHIFT.
THE TEAM REFILLED THE HYDROGEN AND HELIOX TANKS AND RETURNED TO THE PIT TO CLOSE UP FOR THE NIGHT AND PREPARE FOR TOMORROW'S RUN(S).


Two photos attached. Stay tuned for another update tomorrow. I will be joining the team later today.
