What is 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 a wing station?

The wing stations are perpendicular to the leading edge. Wing station zero is typically where the leading edge meets the fuselage. Wing ribs are typically parallel to the wing station. … The wing buttlines are parallel to the airplane buttlines, which run down the length of the aircraft.

What is aircraft station number?

Fuselage or Body Stations Fuselage or body stations help to locate longitudinal points along the fuselage of an aircraft by reference to a zero datum line (usually at or near the forward portion of fuselage). Station numbers forward of datum line are negative (-) and aft of datum line are positive (+) #2.

What is aircraft waterline?

The waterline is the line where the hull of a ship meets the surface of the water. … In aircraft design, the term “waterline” refers to the vertical location of items on the aircraft.

What are the types of aircraft wings?

Number and position of main planes

  • Low wing: mounted near or below the bottom of the fuselage.
  • Mid wing: mounted approximately halfway up the fuselage.
  • Shoulder wing: mounted on the upper part or “shoulder” of the fuselage, slightly below the top of the fuselage. …
  • High wing: mounted on the upper fuselage.

What are the four typical loads on an aircraft?

There are four main load sources acting on an aeroplane – aerodynamic forces, inertia, ground reactions and thrust. The goal of the current work is it to determine its critical combinations.

What is ATA in aircraft?

Definition. A numerical technical classification of all the systems and sub systems on an aircraft which is universally used in aircraft engineering and aircraft maintenance. It was developed by the former Air Transport Association (ATA) since renamed Airlines for America (A4A).

What is the shape of the waterline?

What is the shape of the waterline? The waterline is a curve shape. This curved shape is called the meniscus. Always read the volume at the bottom of the meniscus.

Is it waterline or water line?

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 of an aircraft?

Body buttock lines ( BL ) are measurements left or right vertical plane runing through the aircraft’s longitudinal axis. Expressed as LBL or RBL the may tu be used for fuselage locations, particularly in wide bodied aircraft and also wing location on smaller aircraft.

What is the best wing shape?

The elliptical wing is aerodynamically most efficient because elliptical spanwise lift distribution induces the lowest possible drag.

Why do wings fly?

Airplane wings are shaped to make air move faster over the top of the wing. When air moves faster, the pressure of the air decreases. So the pressure on the top of the wing is less than the pressure on the bottom of the wing. The difference in pressure creates a force on the wing that lifts the wing up into the air.

How many types of wings are there?

There are four general wing shapes that are common in birds: Passive soaring, active soaring, elliptical wings, and high-speed wings. feathers that spread out, creating “slots” that allow the bird to catch vertical columns of hot air called “thermals” and rise higher in the air.
