*the following applies to cars at high speeds*
the usual traditional way of slowing a car down would be to use
brakes or a down shift in gear.
would it be feasible to use an increase in drag aerodynamically to
achieve that effect? for example by install speical roof flaps on
the car to spoil the aerodynamics and to slow it down. beside
reducing the stress on the brakes when down shifting it also
reduces the stress on the engine. it could also act as an emergency
brake. for example, travelling at 130km/h suddenly the driver jams
brake, the ECU would be able to know that the driver is trying to
do an emergency brake, it automaticallly pops the roof flap open
increasing the aerodyamic drag.
other then juz slowing down, instead of juz anyhow putting the roof
flaps, is it possible to calculate an angle where the angle where
the flap is erected produces a lateral turning effect in the car.
an example would be the rudder of an aeroplan. will this lateral
turning effect help when racers turn? in this way racers dont have
to slow down that much as the roof flap reduces speed
too.
