In aircraft hydraulic systems, hydraulic accumulators utilize a compressed nitrogen pre-charge separated from hydraulic fluid by a flexible bladder or piston. During peak operational demands, such as landing gear extension, the compressed gas expands against the fluid chamber to deliver supplemental pressure and volume instantly. When the system operates under nominal conditions, engine-driven pumps recharge the fluid chamber, compressing the nitrogen back to its designated baseline pressure. This nitrogen cushion also absorbs transient pressure spikes generated by rapid valve actuation, protecting sensitive downstream components from hydraulic shock.
According to the passage, how does the nitrogen cushion safeguard hydraulic components?
- ABy generating transient pressure spikes that force the flexible bladder to close
- BBy allowing engine-driven pumps to expand against the fluid chamber during nominal conditions
- By dampening sudden surges in fluid pressure caused by quick valve movementsCevap
- DBy cooling the hydraulic fluid to prevent thermal expansion during landing gear deployment
Cevap
The nitrogen cushion safeguards components by dampening sudden surges in fluid pressure caused by quick valve movements.
The text explicitly states that the nitrogen cushion absorbs transient pressure spikes generated by rapid valve actuation, protecting downstream parts. The correct answer accurately paraphrases this fact by stating that it dampens sudden fluid pressure surges caused by quick valve movements.
