New Axiam White Paper Demonstrates Significant Fuel Savings for Airline Jet Engines

“Fuel costs consume some 40% of an airline’s operating budget," Donald Lohin

Axiam, Inc– --provider of repeatable, integrated engine core assembly processes for commercial turbine engines--announces the availability of a new white paper explaining in detail a significant new approach to engine re-building resulting in substantial fuel consumption savings.

In the new white paper, available free from Axiam, Donald Lohin, Axiam President, describes the continuing problem engine shops have faced for decades:

“The Engine Manual assembly process is a ‘Trial-and-Error’ method developed in the 1950s,” he says in the paper. “It builds rotors to a maximum allowable run-out limit for rotors by offsetting the high points of alternate stages. This procedure often results in relatively ‘bowed’ rotor assemblies, creating performance issues. The addition of weights does not straighten a bowed assembly. The extent to which an engine core is ‘bowed’ determines how quickly performance deterioration and excessive vibration appear.”

Core structure bowing eventually results in common engine issues:
high fuel consumption, low EGT Margin, EGT margin deterioration, low wing time, excessive vibration, high gas emissions, engine surge(s), excessive engine wear, oil leakage/coking, excessive parts failure, bearing failure, blade tip rubbing, shaft rubbing, high spares usage, high turn time, rebuilds, test cell rejects, inconsistent schedules and high test cell trim time. All of which results in subpar engine performance, subpar quality and high costs.

Complete with full-color diagrams and charts, the white paper examines both the need for substantial reduction in fuel costs for every commercial airline, and presents in clear, precise detail how airline management–from CEO to COO and CFO--can achieve real, measurable fuel savings.

“Fuel costs consume some 40% of an airline’s operating budget. Because fuel costs continue to soar–with no end in sight–it is vital for commercial airlines to control their fuel costs, reducing consumption as much as possible while still providing acceptable levels of customer service, safety and operational excellence.

“Recently, Flight Sciences International, the airline industry’s leading designer of successful, commercial aviation fuel conservation programs and Axiam, undertook to develop a new approach to jet engine core builds,” Mr. Lohin added. “This paper describes the successful development of an to approach reduce fuel consumption and related costs, while not compromising performance, TBO and engine efficiency.”
