Difficulty: MediumDirect Fact Retrieval

Read the following technical passage and complete the statement below based directly on the provided facts.

Answer:Hydraulic accumulators in heavy transport aircraft store fluid under pressure to operate emergency brakes and landing gear. A flexible synthetic rubber bladder separates the hydraulic fluid from a sealed chamber of dry nitrogen gas. During preflight maintenance, technicians measure the nitrogen precharge pressure using a dedicated Schrader valve while the hydraulic system is fully depressurized. If the nitrogen precharge drops below 1,500 psi, the accumulator cannot deliver sufficient volume during rapid emergency extension cycles.

According to the passage, the hydraulic fluid is separated from the nitrogen gas chamber by a 【synthetic rubber bladder】.

Answer

synthetic rubber bladder (or flexible synthetic rubber bladder / rubber bladder / bladder)
The passage explicitly states: 'A flexible synthetic rubber bladder separates the hydraulic fluid from a sealed chamber of dry nitrogen gas.' Therefore, the synthetic rubber bladder is the exact component that performs this function.
