AES100 Turboshaft Engine Enters Small-Batch Delivery Phase

AECC Aviation Power disclosed on November 4 that the AES100 engine has obtained both type certification (TC) and production certification (PC) and has now entered small-batch delivery, with orders and market promotion progressing in an orderly manner. The AES100 is a 1,000 kW-class domestically developed civil turboshaft engine designed to power 5–6 tonne twin-engine helicopters, 3–4 tonne single-engine helicopters, and tiltrotor aircraft.

The engine received its TC from the CAAC in 2024 and its PC in April 2025. In June 2025, AECC signed sales and leasing contracts with United Aircraft Group for the AES100 to serve as the powerplant for the 6-tonne-class unmanned tiltrotor transport platform "Lanthanum Shadow R6000".
