A more powerful model of J57 was fitted, and the aircraft structure was lightened.
Since then, most aircraft structures have been specified in alloys of this type.
Despite their strength and low weight, composites have not been a miracle solution for aircraft structures.
The Council should be asked to study the phenomenon of metal fatigue in aircraft structures.
The aircraft structure is made from aluminum tubing, with foam wing ribs.
The investigative teams will include experts on, among other things, aircraft structure and systems, engines, air traffic control and human performance.
Integral tanks are areas inside the aircraft structure that have been sealed to allow fuel storage.
Since these tanks are part of the aircraft structure, they cannot be removed for service or inspection.
The aircraft structure was built from spruce, balsa and maple.
It is used in modern aircraft structures, generally replacing the older 2024-T4 alloy.
