The PW4000 112-inch engine, an ultra-high-thrust model covering the 74,000 to 90,000 pound-thrust class, is the reliability, experience and Extended-range Twin-engine Operations (ETOPS) leader for the 777 aircraft, providing the best customer value.
The engine’s advanced, service-proven technologies including single-crystal super alloy materials, powdered metal disks, and Full-Authority Digital Electronic Control (FADEC) provide excellent operational performance and durability. These features contribute to the engine's excellent environmental performance, which meets with margin all current noise and emissions regulations.
The PW4000 112-inch engine retains the outstanding accessibility and component modularity of other PW4000 family members to reduce maintenance time and cost. For transportability, the engine can be shipped in a 747F aircraft as a complete engine. Also, the fan case is easily separated from the engine's core for split shipment without disturbing the bearing compartments.
Yes, we retrofit legacy systems (e.g., GE Frame 5, Siemens V94.2) with modern digital controllers, typically completing hardware integration within 4-8 weeks. Software migration requires additional validation time.
We recommend annual performance testing under ISO 3977-2 standards. Critical applications (e.g., offshore platforms) may require semi-annual tests with emissions compliance checks.
All rad-hard devices (e.g., FPGA, ADC) are QML Class V certified under MIL-PRF-38535 and tested to MIL-STD-883 Method 1019 for SEU tolerance. Full qualification reports are available upon request.
Our ASICs and power management ICs operate across -55°C to +175°C ambient temperatures, with derating curves provided in military temperature range (MTR) datasheets.
Our PMA parts (e.g., actuators, sensors) hold FAA/EASA Form 1 certification and match OEM form/fit/function. Installation requires SB/MB documentation per FAA AC 23.1529.
All NAS/MS fasteners include full DNA traceability: melt source (AMS 2301), heat/lot numbers, and AS9100-compliant MTRs with ultrasonic test reports.
AOG orders ship within 4 hours for stocked items (FAA-PMA, EASA Part 21G). Non-stock critical parts trigger priority manufacturing with 72-hour max turnaround.
