This patent discloses an improved dynamic seal for the longitudinal slot in a pressurized cylinder of an aircraft catapult system having a shuttle adapted to travel at high speed through the slot. The seal includes a flexible, elongated sealing strip extended along the slot in sealing relation therewith to close the cylinder, and a series of ball detents mounted along the length of the slot on each side thereof for urging inwardly against the sides of the sealing strip thereby providing support for the strip throughout the length of the cylinder. When the shuttle, adapted to guide the strip internally of the cylinder as it passes therethrough, travels through the slot, the ball detents maintain the strip in sealing relation with the slot thereby preventing whipping of the strip forwardly of the moving shuttle.
