Introduction: At the Paris Air Show, the world's largest aero engine manufacturer, General Electric, GE, said that if , Boeing 's intermediate market-level passenger aircraft 797 plans to choose more than two engine suppliers, GE will not be prepared to participate in because the current passenger aircraft market cannot prove its required investment and returns.
June 19, 2017, GE Airways President and CEO David Joyce said that if Boeing chose more than two engine suppliers, it would choose to abandon this project. The company still remembers the "scars" brought by the Airbus SE A330's choice of three engine suppliers 20 years ago.
Boeing's new aircraft is also called the Boeing 797 passenger aircraft. It is a new passenger aircraft proposed by Boeing in 2016. Boeing hopes to have a natural transition product between the Boeing 737 and the Boeing 787, between the narrow body and the wide body, and replace the Boeing 757 and 767 around 2025, which requires about 40,000 pounds-50,000 pounds of thrust engine. Currently, , Puhui, and Rolls-Royce are interested in providing engines to the passenger plane.
Last year's at the Singapore Air Show , Pratt & Whitney quickly negotiated with Boeing, and stated in an announcement that Boeing had fully accepted the concept of gear-driven turbofan engine GTF, and had discussed with Prat & Whitney's potential applications on Boeing's "intermediate market" new passenger aircraft, including aviation engine architecture and evaluation of the upgrade strategy of PW1100G: whether it is possible to support scalable engine design to adapt to the development of new passenger aircraft.
In April this year, Rolls & Rossell also said that it is comprehensively promoting its Ultrafan engine project and is paying attention to the "intermediate market" passenger aircraft proposed by Boeing, hoping to use the new Ultrafan engine as the supporting engine of the passenger aircraft.
A few days ago, on June 16, GE's partner on civil aviation engines Safran also expressed its intention to provide engines for the passenger aircraft, but Olivier Andries, head of Safran aircraft engine business, also said that this depends on Boeing's procurement model for the engine. He hopes that Boeing will adopt the only power engine supplier model, which will allow CFM International to provide greater discounts in pricing.
CFM International is a joint venture between GE, the United States and Safran, France, and is the only engine supplier of Boeing 737 Max passenger aircraft. CFM International is also one of the two engine suppliers of Airbus A320neo passenger aircraft, and GE is also the only supplier of Boeing dual-channel passenger aircraft 777X.
But Boeing has its own ideas for the engine plan of the new passenger aircraft. At the Paris Air Show, Kevin McAllister, head of Boeing's commercial aircraft department, said that Boeing is exploring the use of "three very interesting technical solutions" on the propulsion system of the next generation of new jet passenger aircraft .
This solution is obviously a bit broken industry rules. Joyce said: "What happened? This new passenger plane actually requires three of our companies to spend a lot of money to design a brand new engine. Look at the investment returns in the current engine industry. Unless you can find more application methods immediately, your investment may be wasted in the existing aviation market."
Joyce further explained: "Think about the difference between whether you are the only engine supplier, and then look at the past engine cases and investment reports. If two engine suppliers are used on the new passenger plane, then its investment returns are no longer so good, but now there are 3 suppliers on the new passenger plane." Eric Schultz, head of Rolls-Royce civilian engine, is required to use Eric (Eric) Schulz also expressed a similar view in an interview with Bloomberg: "It has been proven that it has not been very successful in the industry in the past. It is not certain whether it is better to choose an engine supplier or one."
Although Rolls-Royce has made huge profits in the wide-body passenger aircraft market with its Trent series aircraft engines and is also a supplier of some regional and business aircraft, the most popular sales in the aviation market are still narrow-body passenger aircraft, which is basically blank in Rolls-Royce's narrow-body passenger aircraft engines. Rolls-Royce also acknowledged the risk of overcrowding of its product line, so it "pursued" Boeing's new passenger aircraft. However, Rolls-Royce CEO Warren East also said that the premise is "correct business conditions."
Boeing CEO Dennis Mullenberg Muilenburg said in an interview at the Paris Air Show on Monday that the new aircraft had about 250 seats and a range of 5,000 nautical miles. He also said that the new aircraft may be dual-aisle and that "all options" are still under consideration.
Boeing's new passenger aircraft department head McAllister declined to elaborate on the aircraft's engine architecture, saying: "This is just beginning and the game is still early." ”
