The TECH56 program, created in partnership between Snecma and GE in 1998, was designed to lay the groundwork for future generations of CFM56 turbofans, through advanced R&T work on all major components of commercial aircraft engines. The primary objectives were to improve fuel consumption, efficiency, environmental-friendliness, maintenance costs and reliability. Technology demonstrations of engines operating under actual conditions were successfully completed in 2004.
Based on some of the technologies validated by the TECH56 program, Snecma and GE then set up an improvement program specifically targeted to the CFM56-5B and -7B engine models. The two main objectives of this program are to reduce maintenance costs and integrate the upcoming CAEP/6 emission standards.
In 2005 Snecma and GE launched a new technology development program, dubbed LEAP56™, to identify and validate the propulsion solutions needed for future generations of single-aisle jetliners.
The LEAP (Leading Edge Aviation Propulsion) program develops the technologies needed for new or even revolutionary propulsion concepts, to be incorporated in LEAP, a new-generation engine for the next generation of single-aisle jets.
