The Boeing 787 was initially designed to offer two engine options, the General Electric GEnx-1B and the Rolls-Royce Trent 1000. However, this decision would have significant implications for the aircraft's market share and pricing strategy.
Aircraft manufacturers typically prefer to offer a single engine option on their models to reduce development costs and streamline production processes. Nevertheless, airlines often prioritize commonality with other aircraft types to negotiate better deals with manufacturers.
The GEnx initially struggled with fuel burn specifications, but was later rectified by the manufacturer. The Trent 1000 also experienced initial issues, which were quickly addressed by Rolls-Royce.

Despite these early challenges, both engines gained significant traction in the market. However, as time went on, the GEnx began to pull ahead of the Trent 1000 in terms of market share.
The shift in market dominance can be attributed to various factors, including aerodynamic improvements and reliability issues with the Trent 1000. The GEnx's triple-spool design provided a significant advantage during climb and descent phases, resulting in lower fuel burn rates on longer routes.
As the 787-10 variant was launched, Singapore Airlines opted for the Trent 1000, while United Airlines and Continental Airlines selected the GEnx. However, these early orders were later cancelled by Delta Air Lines.

The dominance of the GEnx in the 787 market has significant implications for Boeing's pricing strategy and overall revenue streams. With the majority of orders now committed to the GEnx, Boeing can confidently offer a more competitive price point for its aircraft.
In conclusion, the shift in engine market share on the 787 is a testament to the evolving dynamics of the aviation industry. As manufacturers continue to prioritize efficiency and reliability, airlines will be forced to adapt their purchasing strategies to remain competitive.
Engine failures and reliability issues can significantly impact an airline's operational costs and overall profitability.
