COMAC Receives Additional Orders of GE's CF34-powered ARJ21 Aircraft

COMAC (Commercial Aircraft Corporation of China, Ltd.) held a signing ceremony yesterday at the Zhuhai Air Show with China Aerospace Leasing Co., Ltd. (CASLC) for 20 firm and 20 options of ARJ21-700 aircraft powered by GE's CF34-10A engines. The engine order for the 20 firm aircraft is valued at $155 million USD at list price.

"GE's CF34-10A engines that power the ARJ21 have been operating very well since entry into commercial service in June 2016. The ARJ21 has been demonstrating very good economics and providing great comfort to passengers," said Weiming Xiang, president of GE Aviation Greater China Region. "We will provide our full support to the operator Chengdu Airlines as well as COMAC and look forward to seeing more aircraft enter into service."

COMAC launched the ARJ21 program in 2002, and GE's CF34-10A engine was selected as the powerplant in the same year. The aircraft received Type Certificate from the Civil Aviation Administration of China (CAAC) in late 2014.

The advanced technology of the CF34-10A engine, part of GE's CF34 family, is ideally suited to the design requirement of the ARJ21 aircraft and meets the demanding conditions of China's diverse environment, specifically the hot temperature and high altitude conditions experienced on many routes in Western China. The engine provides the thrust capability to meet aircraft performance requirements and offers customers low-cost operations with a highly reliable, easily maintainable propulsion system.

Based on the CF34-10E engine, the key CF34-10A design features include a wide-chord fan for higher thrust and high tolerance to foreign object damage; 3-D aerodynamic design airfoils in the high-pressure compressor for highly efficient, stall-free operation, as well as better fuel burn and higher exhaust gas temperature margins; a highly durable single annular, low-emissions combustor that meets or surpasses the most stringent emissions standards; and a single-stage high-pressure turbine for lower operating cost.
