Where is the buttock line or buttline of an aircraft? A width measurement left or right of, and parallel to, the vertical centerline. Where is fuselage station No. 137 located?
What is the buttock line of an aircraft?
(aviation, ship-building) A curve indicating the shape of an airfoil or nautical equivalent in a vertical plane parallel to the longitudinal axis of the craft or vessel.
What is aircraft waterline?
In aircraft design, the term “waterline” refers to the vertical location of items on the aircraft. This is (normally) the Z axis of an X × Y × Z coordinate system, the other two axes being the fuselage station ( X ) and buttock line ( Y ).
Where is the fuselage located?
fuselage, central portion of the body of an airplane, designed to accommodate the crew, passengers, and cargo. It varies greatly in design and size according to the function of the aircraft.
What is the purpose of stall strips on airplane wings?
Stall strips are usually located near the inboard leading edge area of the wing. Their purpose being (supposedly) to cause the inboard area of the wing to begin to stall first. This, theoretically, provides a more gradual stall and enables the ailerons to be effective longer.
What is the line that divides the buttocks called?
The intergluteal cleft or just gluteal cleft, also known by a number of synonyms, including natal cleft, butt crack, and cluneal cleft, is the groove between the buttocks that runs from just below the sacrum to the perineum, so named because it forms the visible border between the external rounded protrusions of the
What are aircraft zones?
Zones are designated physical areas of an aircraft that identify where maintenance activities occur. A maintenance task can span multiple zones. In the Zones application, you can create, delete, or activate zones on an aircraft.
Where is the center of gravity located on an aircraft with a tricycle landing gear?
Tricycle gear airplanes are built in the ‘Delta’ configuration, with the airplane’s center of gravity slightly forward of the main gear.
What is datum line in aircraft?
Datum (reference datum)—an imaginary vertical plane or line from which all measurements of arm are taken. The datum is established by the manufacturer. Once the datum has been selected, all moment arms and the location of CG range are measured from this point.
Which area of the aircraft is subject to hoop stress?
Pressurisation of the cabin for high-attitude flying exerts an internal tensile (hoop) stress on the fuselage. Figure 3.6 shows the property requirements for fuselage materials. Important properties for fuselage materials are stiffness, strength, fatigue resistance, corrosion resistance, and fracture toughness.
What is a space inside the fuselage where the crew sits?
Cockpit. a space inside the fuselage where the crew sits.
What are the 3 types of fuselage?
4 Common Types of Airplane Fuselages
#1) Truss. Also known as truss structure, truss is a common type of airplane fuselage. #2) Monocoque. Some airplanes have a monocoque fuselage. #3) Semi-Monocoque. In addition to monocoque, there are semi-monocoque airplane fuselages. #4) Geodesic.
What comes out of the back of an airplane?
Those white streaks planes leave behind are actually artificial clouds. They’re called contrails, which is a shortened version of the phrase “condensation trail.” Airplane engines produce exhaust, just like car engines do. As hot exhaust gases escape from a plane, the water vapor in the fumes hits the air.
What is a Dutch roll in an aircraft?
Answer: Dutch roll is a natural aerodynamic phenomenon in swept-wing aircraft. It is caused by the design having slightly weaker directional stability than lateral stability. The result is the tail of the airplane seeming to “wag” or move left and right with slight up and down motion.
What is a stick shaker on an aircraft?
A stick shaker is a mechanical device that shakes the control column to warn of the onset of stall. A stick pusher may be installed in association with a stick shaker system in aircraft which are susceptible to the deep stall phenomenon.
What is vortex generator on aircraft?
A vortex generator (VG) is an aerodynamic device, consisting of a small vane usually attached to a lifting surface (or airfoil, such as an aircraft wing) or a rotor blade of a wind turbine. VGs may also be attached to some part of an aerodynamic vehicle such as an aircraft fuselage or a car.
