Fuselage reference line. [1][2] The rudder is the primary control of yaw.
Fuselage reference line. It is usually along the plane of symmetry and at a convenient height. A positive yawing motion moves the nose of the aircraft to the right. These are abbreviated as F. FRL Aircraft Abbreviation FRL in Aircraft commonly refers to Fuselage Reference Line, which is a reference line used in aircraft design to establish the location of various components in relation to the fuselage. The fuselage reference line is denoted by FRL. , B. . Take reference point for the wing to be the aerodynamic center (roughly the 1/4 chord point)1 Consider wing contribution to the pitching moment about the c. Motion about this axis is called yaw. All three are given in inches from some arbitrarily chosen reference - so fuselage station 100 is 100 inches away from fuselage station 0. Assume that wing incidence is iw so that, if αw = αF RL + iw, then The straight line used as a reference from which basic dimensions are laid out and major components are located. Sep 16, 2019 · All fuselage station measurements are taken from the reference datum, extending aft along the centerline of the aircraft. Listed below are the numbering systems. Some manufacturers may refer to these as Body Stations (BS) instead of FS, but the principle remains the same. S. See fuselage datum An Example drawn by Nathan Kirschbaum A-A - Vertical Reference Plane B-B - Fuselage Reference Line C-C - Centerline Plane of Symmetry Note: this is the standard three-view layout format The main takeaway, Define the reference area for others! The reference trap wing Source: Stinton, (1927 – 2012), Design of the Airplane Comment: Reference Area(s) May 24, 2020 · $z_0$, the vertical position of the wing with respect to the fuselage transverse reference line $y_\mathrm {C}$. Key points: Airframe reference data, reference datum line, aircraft body, fuselage station numbers, body water lines, body buttock lines, buttock line, wings station numbers, panel numbering Fuselage stations (Fus. [3] These systems are used to locate specific wing frames, fuselage bulkheads, or any other structural member of an aircraft. Several types of systems are used. or FS) are numbered in inches from a reference or zero point known as the reference datum. Like the stations, water line 0 is generally a bit below the aircraft, possibly to have WL 100 at the center of the fuselage, or WL 0 could be at the bottom of the fuselage. and W. See fuselage datum. [1][2] The rudder is the primary control of yaw. This line is essential for ensuring proper alignment and configuration of the aircraft's structure and systems. The straight line used as a reference from which basic dimensions are laid out and major components are located. The yaw axis has its origin at the center of gravity and is directed towards the bottom of the aircraft, perpendicular to the wings and to the fuselage reference line. The contributions of fuselage, nacelle and the power plant are shown as moments about c. g. [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. Fuselage station 185 indicates a location that is 185 inches from the datum of the aircraft. Water lines (WL) designate location in the height of the aircraft, from ground up. Example: FS 137 indicates that the structure or component is located 137 inches behind the reference datum. L. You can probably guess by now that these are holdovers from the marine industry. The Wing Zero-Lift Direction in Aircraft Configurations Station Numbers and Location Identification on Aircraft A numbering system is used on large assemblies for aircraft to locate stations such as fuselage stations. Sta. The three basic references are called fuselage stations, butt lines, and water lines. and denoted by Mf,n,p. 2. yrb8 0tp 26p crofqn goxm6 ysc5mr vn pv nzxxsb jo
