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.

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.

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.

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?

July 13, 2016, ©. Leeham Co, Farnborough Air Show: Mike Delaney, Boeing’s Vice president and General manager for Aircraft development in the Commercial Airplane division, promises unchanged delivery times despite late changes to the company’s 737 MAX line-up.
Delaney went through the changes for the MAX program as part of a larger presentation, outlining the status for all ongoing aircraft developments within Boeing at the ongoing Farnborough Air Show.
05 February 2016, © Leeham Co: In recent Corners, we looked into technologies which have made the new breed of airliners more efficient.
We’ve talked about how new engines can raise efficiency by about 15% and how aerodynamic improvements, like more efficient split winglets, can add another 1%-2% over single blade winglets. We have also looked into modern ways to manufacture the more resilient and lighter composites structures that designers want to use to increase aircraft efficiency.
There is one area which we have not covered: the aircraft’s systems and how these can be made more efficient. An improved system architecture can add the efficiency improvement of a split winglet. So let’s have a look at the trends in aircraft systems.
We start this week with power distribution.

Introduction
Aug. 31 2015, ©. Leeham Co: Last week we started to look at Boeing’s 767 to see if it can serve the passenger and range space which is not well covered by modern aircraft: the 225 passenger/5,000nm sector. Boeing calls this the Middle of the Market or MOM. Boeing recently said that there is some increased interest for the 767. We analyze why and what can be done to increase any chances of it having a new life as a passenger aircraft.
We started with comparing the 767’s different variants to the most likely MOM aircraft from our series “Redefining the 757 replacement requirement for the 225/5000-sector”. We will now continue and look at the 767 in detail, its strong suits and its less efficient areas. We will also discuss what can be made to address the less efficient areas.

10 July 2015, ©. Leeham Co: We have just witnessed the first solar electrical aircraft, Solar Impulse 2, cross the ocean from Tokyo to Hawaii. Today, Friday, Airbus Group will cross the English Channel with a battery powered electrical aircraft, the E-Fan.
How real is electrical flying? Real enough to make demonstration flights like the one to Hawaii and to Calais. Both these aircraft are technology demonstrators but it is symptomatic that they do these hops now, 2015.

We live in the years when electrical cars have gone from exotic one-offs to serial produced products, still expensive but more and more practical. Why should not the aircraft industry follow? Read more
