longeron
Definition
- Noun:
- Structural component: A "longeron" is a main longitudinal structural member of an aircraft's fuselage or wing, running lengthwise to support the frame and bear loads. It is typically a thin, strong beam or spar.
Usage Examples
- Noun:
- The aircraft's fuselage is reinforced by several longerons that run from the nose to the tail. (The main longitudinal beams supporting the body of the plane.)
- During the inspection, the engineer found a crack in the left longeron of the wing. (A structural defect in a key supporting beam.)
Advanced Usage
"Main longeron": the primary longitudinal beam in an aircraft structure.
- The main longeron bears the majority of the bending loads during flight. (The central beam handles stress from bending forces.)
"Longeron failure": a structural breakdown of the longeron, often critical in aircraft accidents.
- A longeron failure can lead to catastrophic loss of structural integrity. (The beam breaking can cause the aircraft to collapse.)
Variants and Related Words
Longeron-like (adj): resembling or functioning like a longeron.
- The bridge design used longeron-like beams for support. (Beams similar to aircraft longerons.)
Longeron assembly (n): the set of longerons in a structure.
- The longeron assembly was riveted to the skin panels. (The group of longitudinal beams attached to the outer covering.)
Synonyms
Spar: a main structural beam, especially in a wing (though spars are often transverse, while longerons are longitudinal).
- The wing's main spar is similar in function to a longeron. (Both are load-bearing beams.)
Stringer: a longitudinal member in a fuselage or wing, often lighter than a longeron and supporting the skin.
- Stringers run parallel to longerons but are smaller. (They work together with longerons.)
