2022年9月15日 · The 737-300 uses CFM56 turbofan engines. This increased thrust (up to 23,500lbf compared to 16,400lbf for the Pratt & Whitney engines on the 737-200), but led to a few design challenges. The larger engine diameter, and low ground clearance of the 737, meant they were placed ahead of the wing.

2023年7月26日 · Each generation of the 737 has been equipped with new and advanced engine families, revolutionizing the aircraft’s performance, fuel efficiency, and environmental impact.
