F1 » Red Bull to appeal Ricciardo exclusion


turbo compounding is the idea of combining the turbo and and electrical generator to increase efficiency of an ICE, which is used from some time ago in heavy machinery albeit with another turbo just spinning the generator (google is your friend). Or you just like being ignorant? And no this is my only alias, don't know the proffesor. @Mark Actually mass flow rate is the best way to limit power, if it was based on volume, it will be very inconsistent, because volume changes with density, which in term changes with temperature. Williams used to super cool their tanks long time ago, MotoGP bikes still do it I think. Mass stays the same regardless. Actually the 100kg per race and 100kg/h is pretty smart and when they get their measuring right will give an equal playing field for all PUs.

Why are they arrogant, because the won several championships in a row? Would your opinion be different if it was another team in the same situation. This DQ doesn't matter that much, what matters is that if all the flow sensors for all the team have some deviation (it won't be the same for every sensor) this gives a car an advantage over others. See it this way, if we have too equal cars, lets say both Mercedes, they both run with real 100kg/h fuel flow. Now in one of the cars the sensors registers a 10% higher fuel flow, that means, for the car to not be DQed, they should run at 90kg/h max, which if we are rather optimistic of the efficiency of the engine (this type of turbo-compounding is said to give 50% thermal efficiency), and we follow the rumors that the Mercedes's PU produce 900 hp, with 10% less fuel means 5% less power, going to 855 hp. Now the other car has a 10% fuel flow error giving it 945 hp with a total of 90hp difference between the too cars.

from stewards decision "b. The Technical Directive goes on to state: “If at any time WE consider that the sensor has an issue which has not been detected by the system WE will communicate this to the team concerned and switch to a backup system” (emphasis added.) c. The backup system is the calculated fuel flow model with a correction factor decided by the FIA." they never did actually tell RedBull to use the back up system
