What does KVF mean in UNCLASSIFIED
KVF stands for Kammtail Virtual Foil. It is a passive flow control device that improves the aerodynamic performance of aircraft by reducing drag and improving lift. The KVF is a thin, airfoil-shaped flap that is mounted on the trailing edge of the wing. When the aircraft is in flight, the KVF creates a virtual airfoil that extends the effective camber of the wing, thereby increasing lift and reducing drag.

For more information of "Kammtail Virtual Foil", see the section below.
How KVF Works
The KVF works by creating a virtual airfoil that extends the effective camber of the wing. This virtual airfoil is created by the flow of air over the KVF, which causes a low-pressure region on the upper surface of the KVF and a high-pressure region on the lower surface. The pressure difference between the upper and lower surfaces of the KVF creates a lift force that acts on the wing.
The KVF also helps to reduce drag by reducing the amount of flow separation that occurs on the wing. Flow separation is a phenomenon that occurs when the flow of air over a surface becomes turbulent and separates from the surface. This can lead to a significant increase in drag. The KVF helps to reduce flow separation by creating a smooth, laminar flow over the wing.
Benefits of Using KVF
There are several benefits to using a KVF, including:
- Increased lift: The KVF increases lift by creating a virtual airfoil that extends the effective camber of the wing. This can lead to a significant increase in lift, which can be beneficial for aircraft that need to carry heavy loads or that operate at high speeds.
- Reduced drag: The KVF reduces drag by reducing the amount of flow separation that occurs on the wing. This can lead to a significant reduction in drag, which can improve the fuel efficiency of the aircraft.
- Improved stability: The KVF can also help to improve the stability of the aircraft by reducing the amount of buffeting that occurs. Buffeting is a phenomenon that occurs when the flow of air over the aircraft becomes turbulent and causes the aircraft to shake. The KVF can help to reduce buffeting by creating a smooth, laminar flow over the wing.
