UTILIZATION, DEFINED.

The LEAP engine is the culmination of cutting-edge technology and unparalleled performance.

MORE UPTIME. LESS DOWNTIME.

A higher utilization of 96% means more flights and more flexibility to fly when and how you want.

SUPPORTS 25-MIN TURN-TIMES

Supporting 25-minute gate turnaround times, which means less time at the gate and more flying.

90 MILES PER GALLON PER PASSENGER

Delivering 20% fuel efficiency, flying with LEAP uses 66% less fuel than driving to your destination.

LONGER TIME IN THE AIR

Flying an average of 10 hours a day and up to 11 flight cycles, every day.

OPENS UP NEW ROUTES

Supporting longer flight legs, enabling flight options of eight hours or more.

A new standard in terms of sustainability

20 percent FUEL IMPROVEMENT

The LEAP delivers a 20 percent improvement in fuel consumption, compared to previous generation, and engines while  maintaining the same level of reliability and life-cycle maintenance costs.

RELIABLE BY DESIGN

Leveraging the successes and unrivalled experience of the CFM56 program, the LEAP engine is built for 99.94 percent departure reliability – which means more time in the air and less time on the ground.

LESS WEIGHT. MORE ROBUST.

Aerodynamically efficient. 3-D woven.  The LEAP engine’s fan blades are manufactured from 3-D woven RTM (Resin Transfer Molding) carbon fiber composites, an industry first for CFM. This technology results in fan blades that are not only lightweight but so durable that each individual blade is strong enough to support the weight of a wide-body airplane like the Airbus A350 or Boeing 787.

500lbs less
per engine

3D printed. Lighter yet stronger.

The LEAP engine is the first engine to use additive manufacturing to “grow” complex, fully dense yet lighter engines. Its fuel nozzles are 25% lighter than previous models and five times more durable than parts manufactured conventionally.

LEAN BURN. LOW EMISSIONS.

The LEAP engine features the second generation Twin-Annular, Pre-Mixing Swirler Combustor (TAPS II). TAPS II reduces NOx emissions by 50%* versus CAEP/6 standards. Unlike traditional combustors that mix fuel and air inside the combustion chamber, the LEAP nozzle pre-mixes these elements to provide what our engineers call lean burn combustion. We just call it revolutionary.

STAYS NEWER, LONGER.

The unique LEAP debris rejection system provides the best erosion protection, preventing sand, dirt, and other harmful particles from reaching the engine core. As a result, the highly durable, more efficient LEAP engine stays newer for longer.

PUSHED TO THE LIMIT

On its way to engine certification, CFM pushed its LEAP test program to the limit. To meet the performance and reliability expectations made to its customers, a total of 60 LEAP engines were built to execute the most extensive ground and flight test certification program in the company’s history.

 

The LEAP-1A, LEAP-1B and LEAP-1C engine models have all been jointly certified by EASA and FAA.

Aircraft Applications

LEAP-1A - Airbus A320neo

24,500 – 33,000 pounds thrust (35 000 at altitude)

LEAP-1B - Boeing 737 MAX

23,000 – 28,000 pounds thrust

LEAP-1C - COMAC C919

27,980 – 30,000 pounds thrust

A NEW ALL-TIME HIGH

CFM has produced and delivered the world’s largest fleet of jet engines in the single-aisle market.  To support unprecedented production rate , As CFM parent companies, both GE and Safran Aircraft Engines have added new manufacturing capability at sites throughout the U.S. and France, making a combined capital investment of more than $1 billion USD since 2005.
