The Use of Active Flow Control to Increase the Acceleration of Airplanes on Takeoff and Reduce the Dependence on Rotation

Case ID:
UA20-050
Invention:

The technology is the utilization of active flow control (AFC) technology in the leading edge to improve the process of airplane takeoff. It will allow for airplanes to perform a take off without rotating. The AFC technology would allow for the airplane to take off with minimal rotation. The small rotation allows the ability to use smaller landing gear size and in result reduces the overall weight of the aircraft.

 

Background:
A notable challenge in aviation and in particular naval aviation is reducing the length required for takeoff and landing runs. Currently, flaps and slats are being used before and during takeoff procedure to increase the drag ratio. The adoption of active flow control technologies will propel the abilities of airplanes takeoff process and could alter the designs of future airplanes to lighter structures.

 

Applications:

  • Take-off and landing airplanes
  • Naval-based airplane operations


Advantages:

  • Reduce the dependence on rotation
  • Major reduction in landing gear size
  • Weight reduction
  • Faster take offs
  • Slower landings
