Introduction
September 19, 2016, ©. Leeham Co: In Part 4 of the article series, we put together an assumed complete Chinese-Russian wide-body aircraft with fuselage, wing, engines, etc. It is now time to understand what kind of performance that can be expected, given the data we have from the wide-body partners, Russia’s United Aircraft Corporation (UAC) and the Commercial Aircraft Corporation of China (COMAC).

We will combine these data with the ones we have deduced as plausible to fill the gaps, given the time frame and technology level that UAC and COMAC intend to use.
Out will come a first estimate of what kind of performance such an aircraft can have in terms of efficiency and payload versus range capability.
Summary:
- We can use all the data we have gathered to make a first estimate of the efficiency of the Russian-Chinese wide-body.
- We also have enough information to do a first payload-range diagram and to compare that with the diagram for Boeing’s 787-9.

Introduction
September 15, 2016, ©. Leeham Co: In Part 3 of this series, we identified the type and size of wing we would have on a new Russian-Chinese wide-body. It’s now time to go through all the considerations around the engines for the aircraft.

The aircraft would enter the market around 2025. We would have to decide on what size engine that would be needed, what engines would be available at the time and could this project motivate any new engine developments.
Summary:
- The Russian-Chinese wide-body as outlined would require engines in the size class of the Boeing 787-9/10.
- GE and Rolls-Royce have been mentioned as engine suppliers. The question would be: will they offer updated 787 engines or new designs and will Russia compete with its announced engine project for the aircraft?

Introduction
September 08, 2016, ©. Leeham Co: Having covered the possibilities of reusing parts of the Il-96 fuselage for a new Russian-Chinese wide-body, it’s now time to look at the existing IL-96 wing and how far this is from a modern design.

The intent is not to propose that the existing wing is reused but rather to check the technology level against western designs and how big a leap it will be for the partners to make a modern high performance wing for the aircraft.
Summary:
- The IL-96 wing is roughly on the technological level of the Airbus A340-300 wing with a bit lower aspect ratio.
- The dimensions are close to what is needed for the new wide-body but sweep and aspect ratio needs to be changed for a new wing.
- A wing for a 2025 long range wide-body also need a more modern construction technology than classical aluminum alloys.

Introduction
September 01, 2016, ©. Leeham Co: In Part 1, we concluded that the existing Il-96 fuselage cross section would be suitable for a new Russian-Chinese wide-body. This means that a lot of experience and existing designs for fuselage sections can be re-used.

Most importantly, it means that mock-ups and cabin sections can be made early in the project to start work on new and better cabin equipment. This is an area where the partners really lag their western competitors.
We will now look at what aircraft capacities can be conceived with the existing Il-96-300 and -400 fuselages and what changes will be necessary to achieve the targeted sizes that Russia’s United Aircraft Corporation (UAC) and Commercial Aircraft Corporation of China (COMAC) have communicated.
Summary:
- The IL-96 fuselage can be re-used for a Russian-Chinese wide-body.
- The existing IL96-300 cabin is on the small side whereas the Il-96-400 cabin is a bit larger than needed.
- The project will likely choose an intermediate size fuselage to reach the targeted 250 to 280 passenger capacity.

Introduction
August29, 2016, ©. Leeham Co: We have now covered the capabilities of the joint venture partners for a Russian-Chinese wide-body and its possible market. Now we will look at what kind of aircraft such a cooperation can create, given technology and other constraints.

There have been bits and pieces leaked to media from Russia’s United Aircraft Corporation (UAC) and Commercial Aircraft Corporation of China (COMAC).
We will look at what has been said and combine that with our knowledge of existing and future technological capabilities of the parties to make predictions for what aircraft the project can produce.
Summary:
- The Russian-Chinese wide-bodywill be made to cover the “small wide-body”market.
- Initial size will be a 250-280 passenger wide-body
- The aircraft will be a twin with engines from either GE or Rolls-Royce.
- Range with 280 passengers will be 6,500nm.

Introduction
August 25, 2016, ©. Leeham Co: Having dissected the players behind the Russian-Chinese wide-body, it’s time to look at what market such an aircraft aims to capture.

The project participants, Russia’s United Aircraft Corporation (UAC) and Commercial Aircraft Corporation of China (COMAC), say they intend to make a 250-280 seat aircraft with a 6,500nm range.
We will look at what market such an aircraft can address from its Entry into Service (EIS) 2025 and over the next 10 years. We will also discuss the constrains that emerges with UAC and COMAC entering the market as new players.
Summary:
- The Russian-Chinese wide-body covers a market segment called “small wide-body” in the Global market forecast made by Airbus and Boeing.
- Based on data in these forecasts, the dominant market during the first 10 years after a 2025 Entry into Service (EIS) would be a captive Chinese market.

Introduction
August 21, 2016, ©. Leeham Co: The discussions around a joint Russian and Chinese development of a 250-300 seat wide-body has been going on for years.
The project got a more concrete form at President Putin’s visit to China in June. On the 25th of June visit, an inter-governmental agreement to develop and market the aircraft was signed.

At the same time Russia’s United Aircraft Corporation (UAC) and Commercial Aircraft Corporation of China (COMAC) agreed to establish a joint venture for the program.
What market is this aircraft trying to address and will it become a serious player in the wide-body market? Will it give the duopoly Airbus/Boeing something to worry about?
We will address these questions in a series of articles. Before going into the questions around the wide-body program, we will look at the players, UAC and COMAC. Are they up to the job of making a competitive wide-body aircraft?
Summary:
- Russia and China enter the wide-body project with widely different knowledge bases.
- China’s first airliner project, ARJ21, just received local certification after years of delays.
- Russia has produced over 10,000 airliners and has made two generations of wide-body aircraft in the size category.
- The latest wide-body aircraft, Ilyushin IL-96, is on the level of Airbus A340-300 from a technological basis.
Pontifications: Twelve new designs in 10 years spurred orders
By Scott Hamilton
Aug. 8, 2016, © Leeham Co.: The book:bill for Airbus and Boeing this year will be hard-pressed to reach one. Airbus has a better shot, given lower production rates. But the recent years of record-setting orders are over for now.
Unlike some, this doesn’t represent a bursting bubble to LNC. Rather, it’s a natural progression of the cycles that are historically seen.
It’s necessary to put some context into the recent years of these unprecedented number of orders.
Bjorn’s corner: Farnborough week
By Bjorn Fehrm
July 15, 2016, ©. Leeham Co, Farnborough Air Show: We have been at Farnborough Air Show this week, the highlight of the year for an aircraft geek like me. This year there were several interesting aircraft that visited the show for the first time.
Embraer brought over the brand new first prototype of the E-jet 190-E2 and the prototype of their military transporter, the KC-390. Bombardier had their first customer/production CS100 from Swiss to visit the show in addition to their Flight Test Vehicle (FTV) no 5. And Lockheed Martin had the F35B, the vertical landing version, come and hover over the airfield the days that were reasonably rain free in the afternoon.
One thing is clear with the new generation of Single Aisle aircraft: their high bypass engines dominate the visual appearance. Figure 1 shows the 73 inch version of the Pratt & Whitney GTF on the E190-E2 prototype. Huge diameter engine on a not so huge diameter aircraft.

Introduction
July 4, 2016, © Leeham Co: The Farnborough Air Show begins next Monday and predictably, focus will be on orders.
With new airplanes from Airbus and Boeing past their development stages, conventional wisdom says there won’t be much new in this arena.
Don’t be so sure.
Bombardier is now on an upward trajectory, but don’t look for a big splash at #FIA16 (for those looking for this year’s Twitter handle). Embraer will have its E190-E2 at the show.
It’s Boeing’s 100th Anniversary and the company is rolling out the history for the show.
Summary
- No new products from Airbus.
- Boeing may have a surprise.
- Low number of orders anticipated.
