PneuDraulics, Inc. (PDI) designs and manufactures aerospace hydraulic accumulators used in commercial and military aircraft hydraulic systems. Aircraft hydraulic accumulators store energy using pressurized nitrogen to maintain system pressure, support emergency operation, and stabilize hydraulic performance during peak demand or temporary system shutdowns.

PDI offers a range of aircraft hydraulic accumulator designs in volumes from 10 to 400 cubic inches. These aerospace accumulators meet the latest Part 25 requirement of four times operating pressure for burst strength and can be supplied with charging valves and pressure gauges for maintenance monitoring. Some accumulator models incorporate a PDI proprietary equalization device that minimizes pneumatic pressure loss over the life of the aircraft.

Certain designs also integrate LVDT position sensing, allowing the accumulator to function as an accumulator with LVDT sensor for precise monitoring of hydraulic fluid volume and system performance.

PDI aerospace hydraulic accumulators are used worldwide on aircraft including Bombardier CRJ NextGen, COMAC ARJ21, Gulfstream G450/G550, Gulfstream G650, and Sukhoi Superjet 100. Known for high reliability and durability, PDI accumulators support critical aircraft functions such as braking systems, hydraulic pressure stabilization, and emergency hydraulic reserve capacity.
