BringBack those beautiful Y250's

The Y250 vortices were the aerodynamicists weapon to

1. Extract air from the edge of the floor, which resulted in additional expansion underneath the floor thereby increasing the suction.

2. Managing the front lower wheel wake by pushing it away from the car thus preventing the wake from being sucked into the floor (due to the low pressure present underneath the floor)

During my time at bellflight we tried using this concept on helicopter rotor hub wake to prevent it from impinging the vertical stabilizer (cool crossover of technology in industries )
