thrust
Sorry,I'm late to the party.On the closing pages of Paul Valkenburg's Race Car Aerodynamics I believe,he showed a Corvette with an engine-driven suction-slot at the base of the rear windscreen.By applying suction,they were able to pull the flow onto the rear deck without separation,cutting drag,without the longer roofline so loved by classical aerodynamicists.The bummer was that the power requirements to run the pump exceeded the power reduction attributed to the drag reduction.Is this germain to the issue of thrust? Has there been a breakthrough in pump design? Or is it a function of where the air is harvested? Help?
