Abstract
The disclosed invention is a passive flow control device, mounted vertically forward of the helicopter launch and recovery area on a ship flight deck. The vertical flow control device reduces the airwake effect on the ship flight deck for safer operation of helicopters during launch and recovery missions from ships. The device is retractable to reduce the ships topside signature and increase the ship's military effectiveness. It can also be modified for maximum effectiveness based on a combination of the ship's topside features, the ship's operation speeds, helicopter operations, and environmental conditions.
