F1 'black magic' aerodynamicists have been using special ducting (F, W,and S-ducts) to create stall conditions and lowering drag on front wings in max speed straightaways or 'sculpt' blown exhausts under the diffuser to gain more downforce on turns. In aviation, they use blown-flap systems to create higher lift in slow speed conditions. They use blown air vented broadly over the rear upper edge of extended flaps. Just like aircraft mechanics' concerns, they will require more maintenance and have duct blockage & rear deck drainage problems.
