The vertical stabilizer is the fixed vertical surface of the empennage. A vertical stabilizer or tail fin [1] [2] is the static part of the vertical tail of an aircraft. [1] The term is commonly applied to the assembly of both this fixed surface and one or more movable rudders hinged to it. Their role is to provide control, stability and trim ...
A Boeing 737 uses an adjustable stabilizer, moved by a jackscrew, to provide the required pitch trim forces. Generic stabilizer illustrated. A horizontal stabilizer is used to maintain the aircraft in longitudinal balance, or trim: [3] it exerts a vertical force at a distance so the summation of pitch moments about the center of gravity is zero. [4]
It may still have a fuselage, vertical tail fin (vertical stabilizer), and/or vertical rudder. Theoretical advantages of the tailless configuration include low parasitic drag as on the Horten H.IV soaring glider and good stealth characteristics as on the Northrop B-2 Spirit bomber. Disadvantages include a potential sensitivity to trim.
The aircraft performance study indicated that when the vertical stabilizer finally detached, the aerodynamic loads caused by the first officer's actions produced 203,000 pounds-force (900 kilonewtons) of force on the rudder, meaning that the vertical stabilizer did not fail until far in excess of the 100,000 lbf (440 kN) of force defined by the ...
These codes comprise one or two letters or digits painted on both sides of the vertical stabilizer, on the top right and on the bottom left wings near the tip. Although located both on the vertical stabilizer and the wings from their inception in July 1945, these identification markings are commonly referred as tail codes.
A twin-tailed B-25 Mitchell in flight. A twin tail is a type of vertical stabilizer arrangement found on the empennage of some aircraft.Two vertical stabilizers—often smaller on their own than a single conventional tail would be—are mounted at the outside of the aircraft's horizontal stabilizer.
The rudder is typically mounted on the trailing edge of the vertical stabilizer, part of the empennage. When the pilot pushes the left pedal, the rudder deflects left. Pushing the right pedal causes the rudder to deflect right. Deflecting the rudder right pushes the tail left and causes the nose to yaw to the right.
Due to buffeting stresses, [2] the stabilizer shaft broke [1] and the B-52's vertical stabilizer came off the plane. It was found 1.5 miles (2.4 km) from where the plane struck the mountain side. [4] With the loss of the vertical stabilizer, the aircraft had lost its directional stability and rolled uncontrollably.
