Opening communication lines between propulsion and airflow poses new questions

On the runway to more fuel-efficient aircraft, one alternative propulsion scheme being explored is an array of electrically powered ducted fans. The fans are distributed across the wing span or integrated into the wing. Researchers have gained new understanding in how the fans and especially their precise placement on the aircraft can affect the cross-conversation between propulsion and the airflow around the wing.
