longeron

(lŏn'jər-ən) pronunciation

A major structural member of an aircraft fuselage, running from front to rear.

[French, from Old French, beam, from long, long, from Latin longus.]

[名]((通例~s))《空》(飛行機胴体の)縦通材, 縦梁(じゅうりょう).

longeron
Interior of a Boeing/Stearman PT-17 showing small channel section stringers.

In aircraft construction, a Longeron is a thin strip of wood or metal, to which the skin of the aircraft is fastened. Longerons are attached to formers (also called frames), in the case of the fuselage, or ribs in the case of a wing, or empennage. In very early aircraft, a fabric covering was sewn to the longerons, and then stretched tight by painting it with dope, which would make the fabric shrink, and become stiff.

Sometimes the terms "longeron" and "stringer" are used interchangeably. Historically, though, there is a subtle difference between the two terms. If the longitudinal members in a fuselage are few in number (usually 4 to 8) then they are called "longerons". The longeron system also requires that the fuselage frames be closely spaced (about every 4 to 6 inches). If the longitudinal members are numerous (usually 50 to 100) then they are called "stringers". In the stringer system the longitudinal members are smaller and the frames are spaced farther apart (about 15 to 20 inches). On large modern aircraft the stringer system is more common because it is more weight efficient despite being more complex to construct and analyze. Some aircraft, however, use a combination of both stringers and longerons.[1]

Cracks in F-15s at US Base in Japan

TOKYO (AP) — Cracks were found in two F-15s deployed in Japan during an investigation that followed the crash of the fighter jet in the United States last month, the U.S. military said Thursday.

The cracks were in the upper longerons — parts near the canopy — on two of the aircraft, which were among 30 inspected F-15s deployed at the Kadena Air base on Japan's southern island of Okinawa, the Air Force said.
