Boeing Yellowstone Project

from Wikipedia, the free encyclopedia

Passenger capacity of existing and future Boeing airliners

The Yellowstone project of the US aircraft manufacturer Boeing aims to replace the product range of civil aircraft with technologically advanced aircraft in the long term. New technologies include an airframe made of composite materials , the replacement of hydraulic systems with electronic systems, as well as more fuel-efficient ducted turbines (such as the Pratt & Whitney PW1000G engine, General Electric GEnx , the CFM International LEAP56 , and Rolls-Royce Trent 1000). The term “Yellowstone” generally refers to the process technology, while “Y1” to “Y3” refer to the respective aircraft.

Yellowstone is divided into three sub-projects:

  • The Boeing Y1 is intended to replace the Boeing 737 product line. It is intended to cover the market for aircraft with 100 to 200 seats and, if introduced, will compete against the Bombardier CSeries , the Embraer E-Jets aircraft family and the planned Airbus NSR family . Whether it will be developed as the second aircraft in the Yellowstone project will be decided in early 2011.
  • The Boeing Y2 is to replace the Boeing 767 and the 777-200 . Y2 originally referred to the Sonic Cruiser . It has been in service as the 787 since 2011 and covers the aircraft market with 220 to 320 passengers, which means it competes with the Airbus A330 , A340 and the A350 family.
  • The Boeing Y3 is set to replace the 777-300 and 747 product lines and serve the market with 300 to 500 passengers. It is also assumed that it will be the last aircraft to be developed in the Yellowstone project and, in addition to the Airbus A380, will also compete against the largest version of the A350 family expected for 2015 , the A350-1000. Even if the Boeing 747-8 can be understood as part of the Y3 program, it is an improvement on the existing Jumbos. In June 2010 it was reported that Emirates, the major operator of the 777, was in talks with Boeing about a new development to replace it.
