Aerodynamic Seals

Kirkhill has pioneered the design & development of thousands of aerodynamic seals over the last 70 years.

These seals have been utilized for many years to close gaps on fixed portions of airframe sections. Essentially, they are static seals used to control airflow between fixed portions of airframe sections such as the fuselage and wing. In addition, they also take up variable gap dimensions due to manufacturing tolerances and reduce chafing between adjacent airframe structures. Aerodynamic seals on aircrafts consistently become more complex due to the increase of use of high lift devices, aerodynamic balance board systems, and movable control structures. The primary function of these seals is to reduce drag by reducing turbulent airflow at these intersections and to control the flow of air over lift elements.
