What is Keel Beam in an Aircraft System? - Click Aerospace
2022年12月13日 · In the realm of aviation, the keel beam is a structure that runs across the belly of the fuselage, connecting the front and rear portions of the aircraft underside. Additionally, the keel beam is also attached to a central wing box, and the entire assembly will have a U-shape as it follows the orientation of the aircraft body’s lower portion.
What does "Keel Beam" mean? - GlobeAir
The Keel Beam is a fundamental structural element in an aircraft's fuselage, providing essential support, rigidity, and load-bearing capabilities. Its robust construction, precise engineering, and strategic integration contribute to the overall safety and performance of the aircraft.
Keel effect - Wikipedia
In aeronautics, the keel effect (also known as the pendulum effect or pendulum stability [1]) is the result of the sideforce-generating surfaces being above or below the center of gravity of the aircraft. Along with dihedral, sweepback, and weight distribution, keel effect is one of the four main design considerations in aircraft lateral ...
Crashworthiness study of a keel beam structure - ScienceDirect
2010年5月1日 · In this paper, crashworthiness of the energy-absorbing keel beam that could be used for sub-floor of an aircraft was numerically studied using finite element software (ABAQUS/EXPLICIT). Effects of various parameters, i.e. web thickness, radius of everting stringer, and friction coefficient, were investigated and the conditions under which the ...
A lightweight energy-absorbing keel-beam concept was developed and retrofitted in a general aviation type aircraft to improve crashworthiness performance. The energy-absorbing beam consisted of a foam-filled cellular structure with glass fiber and hybrid glass/kevlar cell walls.
