bulkhead
- Definição1
- (1) A fireproof barrier separating the engine into various temperature zones. The cool zone houses the fuel, oil, hydraulic, and electrical components, along with their associated systems. The zones may be maintained at different pressures to prevent the spread of any fire from the hot zone. (2) Any transverse partition in the fuselage at a right angle to the longitudinal axis to the body, serving to strengthen, divide, or help give shape to the structure. In the process, it divides the body into two parts.

- Contexto
- The reason why the aft pressure bulkhead was ruptured in flight is estimated to be that the strength of the said bulkhead was reduced due to fatigue cracks propagating at the spliced portion of the bulkhead's webs to the extent that it became unable to endure the cabin pressure in flight at that time.
- In 1985, a Japan Airlines Boeing 7473 suffered a rapid decompression in flight when an improperly repaired rear pressure bulkhead failed (a latent failure, probably with L-H and L-S mismatch involved). The subsequent overpressurization of the empennage and expansion of shockwave due to the explosive breakage of the spherical pressure bulkhead caused control system failure and the destruction of the aircraft with great loss of life.
