Now open to all readers.
Introduction
April 6, 2015, c. Leeham Co. The next 15 years may well be the last new airplane programs of major airliners that look like today’s tube-and-wing aircraft because demands for new efficiency will require go beyond what engines can do within a reasonable size, says Alan Epstein, VP of technology and environment at Pratt & Whitney.
- Part 1 of our interview with Alan Epstein looked at the next new airplane, the Middle of the Market aircraft (MOM). Today’s Part 2 looks beyond MOM (and it’s not DAD).
Major changes to the airframe will have to provide added efficiency gains in combination with new and evolving technology from today’s engines.
The next new airplane, the so-called Middle of the Market (MOM) aircraft, will look like today’s airplanes. The next plane after that, the replacements for the Airbus A320 and Boeing 737 families, will probably be the last iterations of the planes of today. After that, new designs are likely to emerge, Epstein says.
Summary
- Tomorrow’s airplanes need to revise the fuselage design to increase efficiency.
- Airplanes after 2030 may look different than the tube-and-wing configurations of the past decades.
- Four engine airplanes may make a return.

Introduction
Maria Della Posta, SVP Sales and Marketing, Pratt & Whitney Canada
April 5, 2015, c. Leeham Co. Pratt & Whitney Canada (PWC) continues to develop the next generation turbo prop engine despite little interest from Bombardier for a replacement for its slow-selling Q400 or from Airbus, 50% owner of ATR, dominant producer of this type of aircraft.
Maria Della Posta, SVP of sales and marketing, said PWC is confident demand will prevail over the current lack of interest to see a new airplane program launched as early as 2016 or 2017–though she hedges that this could slip a year or two.
Summary
- In the meantime, PWC continues to undertake Performance Improvement Packages (PIPs) for its ubiquitous PW100 series that is now in its 38th iteration.
- Emerging market ambitions could create new opportunities for PWC to put its next engine on new entrant turbo prop producers.
- Airlines seek a new, larger turbo prop than the Q400 and ATR 72.

Introduction
April 2, 2015, c. Leeham Co.: Even as Pratt & Whitney prepares for the entry-into-service of its new
Alan Epstein, vice president of technology and environment, Pratt & Whitney
Geared Turbo Fan engine on the Airbus A320neo, it’s looking ahead to the most likely all new airplane that could be launched as early as 2018 with an EIS in 2025: the Middle of the Market (MOM) airplane, also most popularly known the as Boeing 757 replacement.
Except that this new airplane really isn’t a 757 replacement, but one that is more accurately a replacement for the Boeing 767-200 or the Airbus A300: a twin aisle, 250 passenger airplane with 4,000nm-5,000nm range.
Alan Epstein, vice president of technology and environment for Pratt & Whitney, believe a derivative of the GTF will be on this new airplane.
Summary
- The next new airplane will be lighter and capable of using smaller engines than those used on the 767-200 and A300.
- The MOM will look much like today’s tube-and-wing airplanes.
- The GTF by then will be 8%-10% more efficient than today’s GTF.
- Geared engines will become more common.
Pratt & Whitney sees long-term aviation growth, airline profits

April 2, 2015: Paul Adams, president of Pratt & Whitney, provided an “state of the business” of PW during the second day of the Media Days. We follow our usual format of recapping his comments in paraphrased form.
- We have been in a significant investment phase over the last three years. The biggest is the GTF, We are transition from development to entry into service, first with the A320neo and then the Bombardier CSeries and then the other programs.
- We’ll be driving to increase the aftermarket service.
- 2014 was a transformational year, certifying nine engines (GTF and non-commercial engines). 2015 will be an extremely busy year with flight testing with 10 airframers on four continents.
- The health of commercial aviation is healthy and will continue well into the future. This is driven by urbanization and that only 17% of world’s population has been on an airplane.
- Oil cost has helped make the airlines profitable and so has consolidation.
Pratt & Whitney: material considerations in next generation of engines
April 1, 2015:
- Panel discussion on Manufacturing and Product Technology at the Pratt & Whitney Media Days.
Ed Colvin (EC), VP, New Product Development and Introduction, Alcoa
Lynn Gambrill (LG), PW Chief Engineer, Manufacturing Engineering and Global Services.
Frank Preli (FP), PW Chief Engineer, Materials and Processes Engineering.
Jimmy Kenyon (JK), PW next-generation fighter engine general manager.
JK: We are seeing years of investment and technology starting to deliver new products and technology to the market (referring to the GTF): double digit fuel efficiency, 75% noise reduction. 20 years of technology investment. There are advancements in the engine core. At same time ramping up F35 engine. This is the world’s most powerful fighter engine but at the same time can adapt to vertical takeoff and landing.

Pratt & Whitney at inflection point
April 1, 2015:
- We’re at the Pratt & Whitney Media Days today and tomorrow. We’ll be posting running information in our usual format of paraphrased synopses for such events.
This is PW’s 90th year.
Panel Discussion: “Big Data”
Lynn Fraga (LF), analytics manager in PW Services Group.
Larry Volz (LV), VP and chief information officer.
Matthew Bromberg (MB), president of PW aftermarket unit, providing MRO services, parts customer support.
MB: Big Data is a buzzword in the industry that has mixed connotations and emotions. PW has been in data monitoring business for decades. 13,000 engines have monitoring systems. We are accelerating and doubling down on a challenging path going forward. Read more
Bombardier CS300 analysis vs A319neo, 737-7

Introduction
March 29, 2015, c. Leeham Co: Bombardier’s big bet in the aeronautics sector, CSeries, is well into flight testing, now more than half way toward the 2,400 hours required by Transport Canada before certification can be granted. The first aircraft to be certified will be the smaller 110 seat CS100 but the market is most interested in the larger 135 seat CS300, which has 63% of present orders and commitments, Figure 1.

Bombardier’s new CEO, Alan Bellemare, told reporters last week that the CS100 would be certified during 2015 with entry into service slipping into 2016. The CS300, which is a direct challenger to Airbus’ A319neo and Boeing’s 737-7, should follow six months after CS100. With the CS300 in flight testing and going into service next summer, we decided to have a deeper look at CS300 and its competitors.
Summary
- A319 and 737-7 are shrinks of the market’s preferred models, A320 and 737-8, and as such not the most efficient models.
- The CS300 is the series center-point and it shows. The modern design beats the Airbus and Boeing designs on most counts.
- Part of the modern concepts in CSeries is the well-conceived Pratt & Whitney PW1000G geared turbofan.
- PW’s 73 in fan version of the PW1000G for CSeries is slightly less efficient that the 81 in version for A319neo but CS300 lower weight makes sure this is more than compensated for.
Bjorn’s Corner: Intro, LCC long range and CFM’s LEAP
By Bjorn Fehrm
March 19, 2015: This is the first version of my Corner where I will comment on the aeronautical world as I see it. It will be a mix of tech things (I am an engineer) and my view on things from my European vantage point. Enough on reason and style; lets get started.
LCC goes long range: After AirAsiaX and Norwegian, now Ryanair is going long range, according to Irish Times (or not; the latest news from Robert Wall of The Wall Street Journal is that the board has not approved a long range business plan).
Be that as it may with Ryanair, the key thing is that what happened to the majors on short haul is about to hit them on long haul as well. Short haul LCCs brought about a change in airline economics and in single aisle aircraft. The LCCs, followed by Ultra LCCs, started the trend to denser and denser configurations where the latest trends are sub 29 inch pitch slim-seats and lavatories that started at 37 inch getting slimmed to 31 inch. It has also brought about changes in galleys and emergency exits configurations, all leading to aircraft with higher and higher capacities.
