The concept for the Flybrid flywheel Kinetic Energy. Recovery System (KERS) was originally developed by Jon Hilton and his team when he was technical. The race to develop regenerative braking technology is on and UK-based Flybrid Systems look to have come up with the first workable solution. Solution 1 – the. F1 KERS: Flybrid How KERS Works (the basics) Flybrid. When Max Mosley announced at the British Grand Prix in that he wanted F1 cars to develop.

Rob Thring of Loughborough University’s department of aeronautical and automotive engineering wonders if that’s a fair question.

And with this in mind they have developed flywheel designs that, whilst sacrificing a small percentage in efficiency, massively reduce their stress and become much cheaper to manufacture. Provided the FIA keeps to its guns, every F1 team will have to have regenerative technology if it is to be competitive in The Porsche Hybridintroduced inuses a battery system, in contrast to the previous Porsche GT3 R Hybrid that used a flywheel system.

SMMT runs a series of exhibitions, shows, seminars and missions abroad. Flybrid is unlikely to be used as a retarder on a heavy double-decker bus — Wrightbus has it on trial on the StreetLite single-decker.

WilliamsF1 developed their own flywheel-based KERS system but decided not to use it in their F1 cars due to packaging issues, and have instead developed their own electrical KERS system.

Several automakers have been testing KERS systems. The KERS boost can provide drivers with an additional 80 bhp for up to 7 seconds a lap. In fact, teams were so convinced of the advantage of KERS that many of the teams competing for the constructors title changed their cars mid-season to stay competitive in the title race.


To deliver up to 60 kilowatts of power despite their low mass, they spin at centrifuge-like speeds of up to 60,rpm. Conversely, if you move toward a ratio that would slow it down then it releases energy.

Bosch also offers a range of electric hybrid systems for commercial and light-duty applications. To a Formula 1 car, that means that all the energy that the car possesses while reaching speeds of mph must be transferred to other forms of energy when the car intends to go slower. Opting to develop the flywheel solution they sat down and roughed out the basics of a design. Its resulting containment solution is very robust and was inadvertently tested during the bearing failure mentioned earlier.

Mazda’s regenerative braking system switches batteries for capacitors.

F1 KERS: Flybrid

Retrieved from ” https: The job of KERS is to harvest a portion of this energy and redeploy it into the car as extra horsepower, providing ksrs performance advantage to its driver. Flybrids may also be comparatively cheap to buy.

However, with the current freeze on engine design it would not be possible to re-design the crank to take the extra power. There have also been concerns about the safety of the systems.

The electric KERS was what many teams started off trying to implement into their cars. Drivers have been using it out of slow corners to help reach their top speed sooner as dlybrid as on straights to actually go past what would usually be their top speed.

Retrieved 31 October InMazda flbyrid announced i-ELOOP, a system which uses a variable-voltage alternator to convert kinetic energy to electric power during deceleration. So when does Knichel think we’ll see them on sale? Batteries aren’t the only way to store kinetic energy, though. All other rights, including commercial rights, are reserved to the author.

Webarchive template wayback links CS1 maint: Their second KERS equipped car finished fifth. Retrieved 31 August However, the battery used to store the energy is very prone to battery fires and can cause electric shocks.

Often that would be the driver. Then inAudi Sport’s flywheel hybrid, the R18 e-tron quattro became the first hybrid car to win the legendary Le Mans hour endurance race.

Torotrak has also developed a CVT transmission licensed to Allison in the US for bus and truck applications and has come up with a variable-ratio supercharger. The implementations are similar to that what is used by hybrid passenger cars.

Some passenger car manufacturers have talked about using a KERS implementation in their cars. Xtrac and Flybrid are both licensees of Torotrak’s technologies, which employ a small and sophisticated ancillary gearbox incorporating a continuously variable transmission CVT.

This is an important part of kefs reliability strategy and units can be assessed in the car with accelerometers attached to look for tell-tale signs of impending failure.
