In early aircraft, a tailskid made of metal or wood was used to support the tail on the ground. In most modern aircraft with conventional landing gear, a small articulated wheel assembly is attached to the rearmost part of the airframe in place of the skid. This wheel may be steered by the pilot through a connection to the rudder pedals ...
The empennage of an Atlas Air Boeing 747-200. The empennage (/ ˌ ɑː m p ɪ ˈ n ɑː ʒ / or / ˈ ɛ m p ɪ n ɪ dʒ /), also known as the tail or tail assembly, is a structure at the rear of an aircraft that provides stability during flight, in a way similar to the feathers on an arrow.
The landing gear represents 2.5 to 5% of the maximum takeoff weight (MTOW) and 1.5 to 1.75% of the aircraft cost, but 20% of the airframe direct maintenance cost. A suitably-designed wheel can support 30 t (66,000 lb), tolerate a ground speed of 300 km/h and roll a distance of 500,000 km (310,000 mi) ; it has a 20,000 hours time between overhaul and a 60,000 hours or 20 year life time.
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 in yaw (also known as directional or weathercock stability).
In aviation, a tailstrike or tail strike occurs when the tail or empennage of an aircraft strikes the ground or other stationary object. This can happen with a fixed-wing aircraft with tricycle undercarriage , in both takeoff where the pilot rotates the nose up too rapidly, or in landing where the pilot raises the nose too sharply during final ...
10 wheels [1x2]+[2x4] A Boeing 757-200 from British Airways: 777: 14 wheels [1x2]+[2x6] A Boeing 777-200 from United Airlines. Using 6-wheel bogies, instead of the common 4-wheel bogies (reminiscent of earlier generation Tupolev Tu-154), was visionary for contemporary aircraft at the time of the design of the 777: B-52 Stratofortress
The tail fin, beginning with the E series, is massive. It is 19.17 feet (5.84 m) tall. The stabilizers are of standard T assembly. [5] The tail gunner is located below the fin. All B-17s have a retractable tail-wheel landing gear. The B-17G weights 32,720 pounds (14,840 kg) empty.
Tricycle gear is a type of aircraft undercarriage, or landing gear, that is arranged in a tricycle fashion. The tricycle arrangement has one or more nose wheels in a single front undercarriage and two or more main wheels slightly aft of the center of gravity. Tricycle gear aircraft are the easiest for takeoff, landing and taxiing, and ...
