New single aisles on home stretch

By Bjorn Fehrm

16 Sep 2015, © Leeham Co.: Boeing released pictures yesterday of the first 737 MAX 8 being on the Renton Final Assembly Line (FAL) having completed the wing-to-body joins. With the Airbus A320neo now flying again with both Pratt & Whitney GTF and CFM LEAP test vehicles and Bombardier completing 85% on CSeries (having passed 2,400 hours of flight testing), one can say the new single aisles are on their home stretch.

Original planning had the CSeries entering service in December 2013, nearly two years before A320neo (October 2015) and four years before the 737 MAX (4Q2017). With the 737 MAX now on the FAL one can start to review the Entry into Service (EIS) for all three. It will be tighter than the companies have said.

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.

Summary:

  • Boeing’s 767 has the right cross section for passenger transportation in the 225 passenger/5,000nm segment.
  • It also carries cargo containers, not as efficiently this time. We show what the consequences are.
  • Finally the wing is not the slender wing of the modern aircraft. We show what impact it will have on overall efficiency.
  • Combined with engines from the 1990s, this gives less than stellar fuel economics. We investigate what can be done about this and how much of an impact it will have in today’s low fuel prices.

Aug. 20, 2015, © Leeham Co.: Conventional wisdom credits Bombardier’s CSeries with being the disruptor that prompted Airbus to launch the A320neo, which in turn caused Boeing to launch the 737 MAX and Embraer to launch its E-Jet E2.

But an academic paper by John Slattery, chief commercial officer for Embraer, reveals that David Hess, the former president of Pratt & Whitney, credits Mitsubishi rather than Bombardier as the catalyst for the dramatic changes that followed.

In a paper entitled Resources & Rivalry, A Case Study of The Single-Aisle Commercial Jet Manufacturing Industry, Slattery interview present and former executives of the Big Four airframe manufactures, the former CEO of ILFC and officials of P&W.

The paper provides a chronicle of thinking leading to decisions to move ahead with new airplane projects, including re-engining the A320 and 737 rather than proceeding with new, clean-sheet designs.

The interviews debunk some of the conventional wisdom surrounding the variety of programs. We’ll periodically report the findings of Slattery’s paper, starting with PW and Mitsubishi.

Introduction

04 Aug 2015, © Leeham Co.: Yesterday we started our deeper look at Mitsubishi Aircraft Corporation’s new MRJ90 and compared it with one of the aircraft that it aspires to replace, Bombardier’s (BBD) CRJ900. We outlined similarities and differences in architecture, dimensions, weights and payload capabilities.

We will now finish the analysis with a study of the fuel consumption performance of the two aircraft on a typical regional route network. Finally, we will discuss at what net price a MRJ90 would be motivated against the incumbent regional aircraft CRJ900 from BBD.

Summary:

  • The MRJ’s more efficient engines and more modern wing gives it a lower fuel burn than CRJ900.
  • A lower fuel cost can be compensated with a lower purchase price. We check at what value the per seat mile operating cost of the aircraft would be the same.

August 3, 2015, © Leeham Co.: Mitsubishi Aircraft Corp. today opened its Seattle Engineering Center jointly with local company AeroTEC in advance of the first flight of the MRJ90 in September or October. During the second quarter of next year, four of five MRJ Flight Test Vehicles will be domiciled in Moses Lake in Central Washington for the bulk of the flight testing over the following year. Entry into service is planned for 2Q2017 with launch customer All Nippon Airways.

The engineering center represents the first in Washington State for an aircraft OEM other than Boeing. Mitsubishi will assign 50 engineers from Japan to the new SEC, in South Seattle a short distance from Boeing Field. One hundred engineers will be hired locally.

AeroTEC and Mitsubishi began discussing working together only last January, said president Lee Human, who added that the seven months from January to the opening of the SEC today was remarkable for the speed in which negotiations, contracts, permits and hiring was achieved.

Introduction

03 Aug 2015, © Leeham Co.: Mitsubishi Aircraft Corporation, the company behind Japan’s new regional aircraft, is inaugurating an engineering center in Seattle today and presenting their testing facility at Moses Lake (WA) Grant County International Airport tomorrow. Against this backdrop we decided to look a bit deeper into the MRJ after having done a first comparison on our January article, MRJ90 vs. Embraer’s up and coming E-Jet 175 E2.

Now we compare the 90 seat version, MRJ90, to the aircraft that it aims to ultimately replace, the most efficient regional jet of the present generation, Bombardier’s CRJ900. With lower fuel prices, will the advantages of a new aircraft still be strong enough to create a compelling business case against the CRJ900?

We start with the examination of the two aircraft and will finish in Part 2 with an efficiency comparison over typical regional routes.

Summary:

  • The MRJ90 and CRJ900 are the same size, around 90 seats single class or 80 seats dual class
  • The CRJ900 has an advantage in that it fits in the present Scope Clause for 76 seats regional operations for mainline carriers. The MRJ is too heavy.
  • The MRJ has by virtue of more efficient engines and a more modern wing a lower fuel burn. With today’s lower fuel price, will the difference be large enough to motivate a higher acquisition cost?

Rolls-Royce and Safran, major European engine OEMs with different fortunes.

By Bjorn Fehrm

July 30, 2015 © Leeham Co. Rolls-Royce and Safran, the parent company of CFM partner Snecma, released their Q2 and first half 2015 earnings today. It is interesting to compare these companies as they are in different strategic situations in their dominant business segments, civil turbofan engines.

Civil turbofans constitute 52% of Rolls-Royce total business whereas it makes 54% of Safran’s turn over. Rolls-Royce’s focus has been widebody engines to the point where it exited its part of International Aero Engines, which makes the single aisle V2500 engine, three years ago. Safran on the other hand is heavily invested in the single aisle market through its 50% part in CFM through its Snecma subsidiary.

The present situation and the future outlook for these two companies are intimately aligned with this strategic difference. We look at why and how this will affect their immediate future.

Summary:

  • Rolls-Royce is experiencing migration problems in its widebody turbofan business. Its bread and butter Trent 700 engine is on its way out and it takes until 2018 for the replacement, Trent 7000, to kick in.
  • Other programs are only growing slowly: the Trent 1000 for Boeing’s 787 or Trent XWB for the Airbus A350.
  • Safran civil turbofan business Snecma is enjoying record sales and deliveries through its CFM joint venture with GE.
  • Despite sharing its revenue 50:50 with GE, the business turnover is the size of Rolls-Royce turbofan business today and larger tomorrow. Profit margins are three times higher.

Bjorn’s Corner: hot summer, hot engines

By Bjorn Fehrm

By Bjorn Fehrm

17 July 2015, ©. Leeham Co: It is summer in south of Europe and we have had over 30°C/86°F for weeks. It makes one realize the conditions where the engines have to work over their flat rating point in the Middle East.

Aircraft engines are a bit fidgety. They don’t like temperature although they are made to sustain that their hottest parts, the nozzle and first turbine after the combustor, gets scalded to 1700°C/3,092°F or more.

Go down to the very back end of the engine and we come to where the key engine parameter, EGT (Exhaust Gas Temperature), is measured. It determines a lot of things, among them the time the engine stays on wing. Things are typically 700°C/1,832°F cooler here and this is where a reliable temperature measurement probe can be placed. Based on its values, the total health of the engine’s core is determined. It is also a key input whether the engine shall be throttled back in a hot take-off like in the Middle East.

Pontifications: ExIm reform

By Scott Hamiltn

By Scott Hamilton

July 6, 2015, © Leeham Co. The US ExIm Bank authorization expired last week. As readers know, I’m a strong advocate of renewal of the authorization. Boeing, and other companies, hope reauthorization can be achieved this month.

I won’t restate the reasons I think ExIm should be reauthorized, nor my utter disdain for the right-wing Republicans and Tea Party types who don’t get that the Bank helps Boeing sell airplanes and sustain or create jobs. I’ve written about this many times, and the competitive disadvantage Boeing will have vs Airbus, whose European Credit Agencies will take full advantage of this.

But there are some points on the “other side” to revisit.

CSeries performance improvement demystified

By Bjorn Fehrm

Subscription required

Introduction

July 6, 2015, © Leeham Co. Bombardier presented a slew of new data for their CSeries aircraft during Paris Air Show. Listening to Bombardier (BBD) officials it sounded like there was only positive news: increased range, better fuel economy, better field performance and lower per seat costs.

We have commented on the released information in two articles when at the Paris Air Show, “Bombardier makes it official: CSeries exceeds advertised numbers” and “CSeries range even better than Bombardier revealed.” We now follow up these articles with an analysis of the furnished figures to reveal how these improved performance figures were achieved.

Aircraft programs use sophisticated modeling tools to understand what performance a finished aircraft will have. A 10% range increase with standard payload from 2,950nm to 3,300nm does not come from any miscalculations with such tools. Nor does it come from claimed lower fuel consumption due to lower airframe drag alone.

There are other contributing factors. Using our proprietary model to identify the factors, we explain how BBD has achieved the claimed higher performance.

Summary:

  • We analyze where the range increase come from and how it affects other performance parameters
  • We also analyze where the improved per seat costs of the CSeries comes from. Lower aircraft costs or other factors?
  • Finally we look at the promised future performance improvements and discuss where these are to find and if they are plausible.
