What are buttock line stations?
buttock lines are distanced measured in inches, right and left from the vertical centerline of the fuselage. These lines run parallel to the vertical centerline. These lines are numbered just as fuselage stations are numbered.
What is a wing station aircraft?
Wing stations are measured from the centre line. of the aircraft and are also given in inches left or right of the centre line. Vertical position from a. ground line or horizontal datum can be known as a Water Line (WL) or Buttock Line, given as. a dimension in inches from the horizontal datum.
What is the difference between water line and buttock line in aircraft?
The Z-axis is positive pointing upward and is known as the water line (WL). To complete a right-handed coordinate system, the Y-axis is positive pointing along the plane’s right wing. The Y-axis is usually called the butt line (BL) but is sometimes referred to as the wing station (WS) as well.
What is a station number in aviation?
Fuselage stations (Fus. Sta. or FS) are numbered in inches from a reference or zero point known as the reference datum. [Figure 1] The reference datum is an imaginary vertical plane at or near the nose of the aircraft from which all fore and aft distances are measured.
What is buttock line in aviation?
buttock line (plural buttock lines) (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.
Where is the buttock line or Buttline of an aircraft quizlet?
Where is the buttock line or buttline of an aircraft? A width measurement left or right of, and parallel to, the vertical centerline.
What are the four stresses to be considered when building an aircraft?
Stresses on the wings, fuselage, and landing gear of aircraft are tension, compression, shear, bending, and torsion. These stresses are absorbed by each component of the wing structure and transmitted to the fuselage structure.
What is a water line called?
the line in which water at its surface borders upon a floating body. water level (def. 2). Also called watermark.
Is waterline a word?
Word forms: waterlines The waterline is a line, either real or imaginary, on the side of a ship representing the level the water reaches when the ship is at sea.
Where is the buttock line or Buttline of an aircraft?
