Introduction

February 12, 2018, © Leeham Co.: In the fourth article about the Chinese/Russian wide-body, CR929, we analyzed the engine selection for the aircraft. Now we continue with a first performance analysis of the CR929 against its main competitors, the Boeing 787-9 and Airbus A330-900.

We will use the preliminary data we have collected for the CR929 and compare this to the data for the 787-9 and A330-900. It’s the first analysis, on preliminary information. But there is enough knowledge of the key parameters to use our performance model to draw the first conclusions about the CR929’s positioning in the market.

Summary:
  • The CR929-600 is modeled closely after the 787-9. The technology for structures, systems, engines and aerodynamics are similar.
  • With a similar payload capacity, the fuel consumption should be better as the CR929 is defined with a lower maximum range.
  • It’s wider cabin eats up the weight and drag advantage, however. There will be little difference between the efficiency of the 787-9 and the 15 years younger CR929.

Pontifications: Airbus easily leads narrow-body backlog, Boeing ahead in wide-bodies

By Scott Hamilton

Feb. 5, 2018, © Leeham Co.: Two thousand seventeen is over and the numbers are in.

Airbus continues to have a commanding lead over Boeing for single-aisle, neo v MAX backlog.

Although Airbus got pounded by Boeing in wide-body orders last year, the backlog tilts only slightly in Boeing’s favor.

Introduction

February 1, 2018, © Leeham Co.: In the third article about the Chinese/Russian widebody, CR929, we looked at the challenges the aircraft poses to the involved manufacturers. Now we continue with analyzing the project’s engine needs.

The CR929 is sized to use engines from the Boeing 787 project. Both GE Aviation and Rolls-Royce got Request for Proposals (RFPs) on 22 Dec. 2017. In addition, the Russian and Chinese engine industry wants to develop an engine for the project.

Summary:

  • The Chinese and Russian widebody program needs engines in the 75,000lbf thrust class.
  • The project’s engine specification is closely modeled after the engines available from the Boeing 787 project.
  • In addition to the available 787 engines, the Chinese and Russian engine industry is trying to unite behind a joint engine proposal.

Introduction

January 25, 2018, © Leeham Co.: In the second article about the new Chinese/Russian widebody, CR929, we looked at the size of the aircraft and its passenger capacity. The CR929 can be best described as a shorter range version of Boeing’s 787-9. We also presented the chosen technologies for the project.

Now we continue and look at the challenges the aircraft poses to the involved manufacturers. Neither of them (COMAC of China and United Aircraft of Russia) have developed and certified an aircraft like the CR929 before.

Summary:
  • The Chinese and Russian widebody program has high ambitions. The structure shall be composites and the systems state of the art.
  • We now go through the aircraft’s chosen technologies and review what experience base the Chinese and Russian aeronautical industry has and what challenges they will face. Read more

Introduction

January 18, 2018, © Leeham Co.: In the first article about the Chinese/Russian widebody, the CR929, we described the route to a joint program company and the launch of the project.

We now analyze the aircraft, based on available information. With the information, it’s possible to model the aircraft in our performance model and get the first understanding of performance and efficiency.

Summary:
  • The CR929-600 is closely modelled after the Boeing 787-9. The overall design and dimensions are similar.
  • The major difference to the 787-9 is in cabin width, allowing comfortable nine abreast seating, and the Maximum Take-Off Weight (MTOW).
  • The decision to design CR929-600 for a lower MTOW has restricted range to 6,500nm with the nominal cabin capacity of 280 passengers.

Chinese and Russian Widebody Project takes shape

Introduction

January 15, 2018, © Leeham Co.: The Chinese and Russian Widebody program started in earnest over the last year. After signing a joint venture agreement in 2016, the project now has a joint management company, CRAIC, formed 22nd of May 2017, and standing for China-Russia Commercial Aircraft International Corporation.

The company will have final assembly and management located in Shanghai.  The aircraft has also got its final name, CR929-600. It will hold 280 passengers in a three-class cabin with a range of 6,500nm, Figure 1.

Summary:
  • The Chinese and Russian widebody program has taken off after the joint company was established spring 2017.
  • The organization of the company is set, with the Chinese taking the rudder by the power of a five times larger market and economy and a 10 times larger population.
  • The joint company, CRAIC, issued its first vendor RFP to GE and Rolls-Royce before Christmas for the aircraft’s propulsion system.

Pontifications: 2018 is a year of Transformations

By Scott Hamilton

Jan. 8, 2018, © Leeham Co.: This is going to be a year of transformations.

This might be viewed with puzzlement by some. After all, only minor-modification models will be entering service this year: the Airbus A350-1000, the Boeing 737-9, the Airbus A319neo and the Boeing 787-10. The first flight of the 737-7 should occur.

Flight testing continues for the Mitsubishi MRJ90, the COMAC C919 and Irkut MC-21.

The proposed deal between Airbus and Bombardier should receive government approvals this year. Talks between Boeing and Embraer may or may not result in a combination of some kind.

The Big Deal, however, resides in Everett (WA).

United Aircraft’s and COMAC’s eventful year

By Bjorn Fehrm

January 03, 2018, ©. Leeham Co: Both United Aircraft Corporation (UAC) and COMAC got their single-aisle airliner projects into flight test during 2017. The MC-21 and C919 had their first flights within less than a month of each other, with the Chinese C919 first at 5th of May, followed by the Irkut MC-21 on the 28th of May.

Superficially the aircraft and projects are similar. Both are 150-220 seat single aisle projects in the mold of Airbus’ A320neo and Boeing’s 737 MAX programs. Looking a bit closer, they are different. One is extending the state of the art in several areas; the other is playing safe.

Introduction

June 15, 2017, ©. Leeham Co: We continued the comparison of Irkut’s MC-21 and COMAC’s C919 last week with an analysis of the cabins and systems. The week before, we compared project time plans, structures and aerodynamics.

Now we finish with an analysis of the economics of the aircraft.

Summary:
  • The MC-21 is the more advanced aircraft of the two. It uses carbon composites for the wings and empennage.
  • Coupled with more refined aerodynamics, the MC-21 offers a higher efficiency than the more classical C919.
