Why do airplanes have vertical stabilizers?
The stabilizers’ job is to provide stability for the aircraft, to keep it flying straight. The vertical stabilizer keeps the nose of the plane from swinging from side to side, which is called yaw. The horizontal stabilizer prevents an up-and-down motion of the nose, which is called pitch.
What is a Strake on an airplane?
Strakes are small blade-like devices mounted on aircraft that enhance aerodynamics by directing airflow over certain control surfaces at specific angles of attack. Usually located on the upper surfaces of the engine’s large fan section, these devices produce bands or ribbons of smooth airflow at high angles of attack.

What does a strake do on an airplane?
In aviation, a strake is an aerodynamic surface generally mounted on the fuselage of an aircraft to improve the flight characteristics either by controlling the airflow (acting as large vortex generators) or by simple stabilising effect. In general a strake is longer than it is wide,…
Why does an airplane have a vertical tail?
If an airplane encounters strong winds, the vertical stabilizer will prevent it from shifting off under the force of the wind. Technically, airplanes don’t have a vertical tail; they have a vertical stabilizer, which is found on the tail. The purpose of the vertical stabilizer is to stabilize the airplane during flight.
Where are the ventral strakes located on a plane?
One or two ventral strakes are sometimes positioned under the fuselage, as large vortex generators, to provide a better tail surfaces efficiency. Typical examples can be seen on the SOCATA TB family or the Lockheed F-104 Starfighter .
Why are strakes used on supersonic and subsonic planes?
On both supersonic and subsonic types, smaller strakes are sometimes applied to the forward fuselage to control the fuselage flow at high angles of attack; for example, the Concorde SST had small nose strakes “to get a better directional stability”.
