FLYBRID KERS PDF

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. When the car brakes, this energy is usually transferred to heat and sound energy that, for the purposes of the car and its driver, is lost. The job of KERS is to harvest a portion of this energy and redeploy it into the car as extra horsepower, providing a performance advantage to its driver. The sport has often been associated with a negative contribution to the environment and the introduction of KERS was an attempt to discredit that reputation. At the time of introduction, many road car manufacturers were beginning to offer hybrid cars which used a similar principle to harvest and reuse energy and so the concept of KERS was one that the public could quickly understand and appreciate.

Tuktilar If the flywheel, rotating at thousands of revolutions per second, is freed from its constrains, it could inflict heavy damage on anything it collides with. Halfway fpybrid the traditional motor and the fully electric Nissan Leaf or the Volkswagen e-Up! That reduces the load on the engine, cutting diesel usage and exhaust emissions.

At the heart of Flybrid is a 60,rpm flywheel that weighs a modest 8. Currently designs favour taking the drive from downstream of the transmission, although there are advantages to applying the drive direct to flybrjd engine.

The sport has often been associated with a negative contribution to the environment and the introduction of KERS was an attempt to discredit that reputation. To achieve this they upped the speed of the flywheel massively to 64,rpm, which allows a smaller, lighter flywheel but also means it has to be contained in a very robust structure flubrid case of failure. While KERS could still provide even more power for longer to Formula 1 cars, there are several reasons why the current systems are not reaching their full potential.

The KERS boost can provide drivers with an additional 80 bhp for up to 7 seconds a lap. However, with the current freeze on engine design it would not be possible to re-design the crank to take the extra power.

Vodafone McLaren Mercedes began testing of their KERS in September at the Jerez fltbrid track in preparation for the F1 season, although at that time it was not yet known if they would be operating an electrical or mechanical system. Once the company started developing the technology, it quickly became clear to Hilton and Cross that while F1 will make some money, the real growth will be in road cars. Torotrak was delighted to have won it.

At the time of introduction, many road car manufacturers were beginning to offer hybrid cars which used a similar principle to harvest and reuse energy and so the concept of KERS was one that the public could quickly understand and appreciate. These were a flywheel construction that would remain intact at these speeds, containment that retains everything in a crash or a failure, a vacuum seal and a bearing solution.

Hilton is certain that Flybrid still makes sense even in a climate of declining oil prices. Show 25 25 50 All. The amount of energy a flywheel stores comes down to its mass and the speed at which it rotates; prototypes have provided an 80bhp boost.

Finally, a clutch separates the drive if the revs move beyond the limits of the system. Order by newest oldest recommendations. The first of these systems to be revealed was the Flybrid.

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.

Lfybrid making hybridisation more accessible and affordable, we can make a real impact on fleet emissions and running costs. The vehicle remained in use so equipped until This is an important part of the reliability strategy and units can be assessed in the car with accelerometers attached to look for tell-tale signs flybrkd impending failure.

In Formula 1 this would be infeasible. There are two main implementations of the KERS flybrie and they differ in how the energy is stored. Porsche is currently developing an electrical storage system. And battery disposal poses its own environmental problems. This is a secure area and requires you to be. Kinetic energy recovery system — Wikipedia The recovered energy is stored in a reservoir for example a flywheel or high voltage batteries for later use under acceleration.

Solution 2 — the housing Obviously, the company knows that one major injury or fatality associated with the system foybrid spell the end of the technology and the company, so safety has been a top priority throughout the project.

Formula 1 cars have a maximum weight limit, and the components can weigh up to 45 kilograms. Instead the energy is used in addition to the current engine.

In fact, damage was relatively minor, being confined to the flywheel and the containment rings, while the housing was undamaged and able to be re-used. Consider the hybrid car. The company is already in talks with car manufacturers and one potential customer is applying for government money to fund a development project with Flybrid. When the bus slows down the Flybrid system captures kinetic energy, which is transferred to the flywheel and released when the driver accelerates again.

Instead, the team opted to develop a totally hermetic shaft seal. Related Posts

I had a chat with managing partner Jon Hilton who talked me through how the system works and what they do to make the devices safe: This is our demonstrator device for a Formula 1 KERS so the layout of it is correct. The output from middle gear to the car is adapted for every individual car so this is the core bit that would be fitted to any car. Control pistons manage the ratio within the CVT. It contains a clutch, an epicyclic gearbox and a flywheel. Controlling the position of the levers manages the torque transfer within the CVT, and therefore how much energy is stored or released. The energy is stored in the flywheel which spins at 64, rpm. This device has an outer containment structure made of carbon fibre which is extraordinarily strong.
