Audi is running a flywheel in the R18.joseff wrote:I take it as a sign of the flybrid system not working at all.
Has anyone managed to get it to work in actual racing though? All I can find is a press release and a youtube video about Dyson Racing from 2012.
I think the Audi flywheel system transfers power to/from the transmission using electric motors, whereas the Nissan system is purely mechanical....?matt21 wrote:Audi is running a flywheel in the R18.joseff wrote:I take it as a sign of the flybrid system not working at all.

kooleracer wrote:I thought that all that talk about the Nissan project being a major cock up was fake. But this performance from Nissan is SHOCKING. To be 20 sec off the pole time and even been out qualified by the ByKolles car that has been a real dog the whole season. The Rebellion is atleast within 10sec of pole with far less resources. Nissan should pack up and save the embarrassment of being outpaced by LMP2 cars. The worst marketing for Nissan in years so far, this debacle. The even didn't build a engine for this project they just took the engine from the Super Formula project. Ben Bowlby please design a car that actually works...wannabe Gordon Murray. Don't understand why Nissan would tarnish they reputation in this major way. Should have skipped their entry this year after their poor test results.
The three Nissan GT-R LM NISMOs finished Thursday's qualifying practice sessions at Le Mans in 12th, 13th and 14th positions in LM P1. The #22 car was the top finisher in the hands of Harry Tincknell (GB), closely followed by Jann Mardenborough (GB) in the #23 car, which is the second full-time WEC entrant.
The three cars completed over 2,000kms during qualifying at Le Mans, gathering precious data and improving with every lap.
"We continue to make progress every time we go out on track," said Nissan's LM P1 Technical Director Ben Bowlby. "We've gone faster with each session, despite dealing with red flags, slow zones and changeable weather conditions. We got some good dry running in today though and this has helped us a lot. Remember that we are tuning the car for Le Mans and developing the car all at the same time. We've got to the end of qualifying with three cars in one piece and a tonne of data so I'm happy with that."
Harry Tincknell was on an even faster lap at the end of Thursday's final session but had to back off for yellow flags. The British racer was happy to report that many of Wednesday's problems have been solved.
"Thursday was much better than Wednesday," he said. "I think I was five seconds faster in the final session so we're definitely doing something right. The boys were mega as they changed the clutch for me in 30 minutes and in reality that should take an hour. It's good to be the fastest Nissan and I was up on that final run so we are definitely headed in the right direction. We still have a long way to go but I'm pleased with progress."
The race team has a full day today to prepare the cars for the 2015 Le Mans 24 Hours, which gets underway on Saturday at 15:00hrs.
BTW, are they allowed to put energy from HERS to the MGU at the wheels directly?Steven wrote:... while Porsche has a battery system, charged via HERS and KERS.
The Flybrid is a ully mechanical flywheel/cvt kers. It was raced in 2011 by Hope racing. The problem with the Flybrid system is its power/energy density don't make it attractive on a privateer budget especially when the factory teams race with 2-3 times the hybrid power.joseff wrote:The Audi flywheel is electric, so it's pretty much insulated from drivetrain shocks & vibrations.
Correct me if I'm wrong, but the Torotrak/flybrid system seems to be fully mechanical, with a CVT connected directly to the flywheel.
yes, but that energy is included in their allocation of 8 Mj/lap; it's not "for free" as it is in F1matt21 wrote:BTW, are they allowed to put energy from HERS to the MGU at the wheels directly?Steven wrote:... while Porsche has a battery system, charged via HERS and KERS.
I'm pretty certain they'll be making a song and dance about being the fastest, and best placed, FWD racecar at Le Mans after the race has finished....kooleracer wrote: Don't understand why Nissan would tarnish they reputation in this major way.

I'm sure they'll keep very quiet on the reason it is FWD is because half the power train doesn't work.machin wrote:I'm pretty certain they'll be making a song and dance about being the fastest, and best placed, FWD racecar at Le Mans after the race has finished....kooleracer wrote: Don't understand why Nissan would tarnish they reputation in this major way.

No i look for that option but you cannot bend the rules around. All MGU must in WEC 1st go to the ES and vice versa. So tehnicaly is energy flow ERSK<-->CE<-->ES<-->CE<-->HERS no like F1 ERSK<-->CE<-->HERSenri_the_red wrote:yes, but that energy is included in their allocation of 8 Mj/lap; it's not "for free" as it is in F1matt21 wrote:BTW, are they allowed to put energy from HERS to the MGU at the wheels directly?Steven wrote:... while Porsche has a battery system, charged via HERS and KERS.
