Abstract
Example active flow control systems and methods for aircraft are described herein. An example method includes supplying pressurized air to a plurality of nozzles. The nozzles arranged in an array across a control surface of an aircraft, and the nozzles are oriented to eject the pressurized air in a substantially streamwise direction. The method further includes activating the nozzles to eject the pressurized air in sequence to create a wave of air moving in a spanwise direction across the control surface.
Claims19
A method comprising:
- supplying pressurized air to a plurality of nozzles, the nozzles arranged in an array across a control surface of an aircraft, the nozzles oriented to eject the pressurized air in a substantially streamwise direction;
- activating, during a first time period, the nozzles to eject the pressurized air in sequence to create a single wave of air moving in a spanwise direction across the control surface;
- and
- activating, during a second time period, the nozzles to eject the pressurized air in sequence to create a first wave of air and a second wave of air occurring simultaneously and moving in the spanwise direction across the control surface.

An apparatus comprising:
- a plurality of nozzles arranged in an array across a control surface of an aircraft, the nozzles oriented to eject air in a substantially streamwise direction;
- an air source coupled to the nozzles;
- and
- a controller to:
- activate, during a first time period, the nozzles to eject air in sequence in accordance with a first wave pattern to create a narrow wave of air moving in a spanwise direction across the control surface;
- and
- activate, during a second time period, the nozzles to eject air in sequence in accordance with a second wave pattern to create a wide wave of air moving in the spanwise direction across the control surface.
