Pontifications: Hawaiian Air ponders A380
By Scott Hamilton
Oct. 31, 2016, © Leeham Co.: Hawaiian Airlines continues to ponder the possibility of acquiring one or two Airbus A380s, its CEO said on the third quarter earnings call—something that raises eyebrows and a lot of questions with industry officials.
Mark Dunkerley, responding to a question on the call, said there are two or three routes that could support the giant A380.
Bjorn’s Corner: Turbofan engine challenges, Part 1
By Bjorn Fehrm
October 28, 2016, ©. Leeham Co: Before we go into the details on the innards of airliner turbofans, we will look at some basics. We do that so that everyone is on the same page.
A turbofan engine generates thrust by pumping air out the back of the engine. This air has a higher speed than surrounding air. Air is actually quite heavy: it weighs 1.2kg per m3 at sea level. By kicking out air at an overspeed in relation to the aircraft, thrust is generated.
In a modern turbofan, the kicking gets done by the fan to 80-90% in the modern By Pass Ratio (BPR) 8-10 engines. A single aisle engine generating 10 tonnes of thrust throws around 350kg of air per second backwards at close to sound speed in a take-off situation. To drive the fan to do that, there is a lot of shaft horse-power needed, around 30,000hp.

These hp are generated by the core. The thermodynamic cycle to generate all these hp in a jet engine or turbofan core (we call both a gas turbine) is like the one in a normal car engine, Figure 1, with the difference that it is a continuous cycle.
We will now go through this cycle in steps. Read more
Counting down to 737-10, NMA
Subscription Required
Introduction
Oct. 27, 2016, © Leeham Co.: Boeing faces decisions in the near term on whether to proceed with the 737-10 stretch of the MAX 9 and the New Mid-range Airplane (NMA) to serve the Middle of the Market sector (MOM).
The 737-10 is intended to compete with the Airbus A321neo, stemming significant bleed at the top end of the 737 line.
The NMA will address the top end of the MOM sector, carry more passengers and have more range than the Boeing 757 and A321neoLR.
Boeing still has critical issues facing it before proceeding with either airplane.
Summary
- A simple stretch to create the 737-10 has technical and operational issues.
- The proposed date for entry-into-service still gives Airbus an insurmountable lead.
- The market for the 737-10 remains limited. Is the return on investment there?
- The market for the NMA is identified in the abstract—but price will be a key driver.
Visit to Bombardier for airBaltic CS300 roll-out
By Bjorn Fehrm
October 27, 2016, ©. Leeham Co: This week we have been at Bombardier (BBD) Mirabel Airport outside Montreal to observe the roll out of the airBaltic CS300 CSeries model and to later test fly the aircraft at BBD’s Wichita facility.
The preparation for the test flight and the flying experience will be described in subsequent articles.

airBaltic will take delivery of the first CS300 by the end of November. This event was for Baltic media to see the aircraft and its final livery for the first time. It was fresh from the paint shop. The group also was able to see the CSeries Final Assembly Line (FAL) and to ask questions to airBaltic CEO Martin Gauss.
Boeing beats estimates on one-time gains
Oct. 26, 2016: Boeing Co. beat analyst estimates on one-time gains but also reported that it raised earnings guidance for the full year.
The press release with full details is here.
Revenues were down 2% year-over-year to $72.1bn. Operating earnings fell 42% to $3.65bn but net earnings fell only 21% due to gains related to taxes. Commercial deliveries were down by 17 airplanes as Boeing transitions from the 737NG to the 737 MAX.
Airbus results depressed from continuing delivery delays
Oct. 26, 2016: Airbus Group reported that its nine months financial results continue to be depressed by delivery delays in the A320neo and A350-900 programs.
The Group reported revenues of €43bn for the period and charges that lowered profits.
Net cash fell by nearly €5bn from the same period last year. Earnings at the Commercial unit fell 59% YOY.

Pontifications: Rockwell buying B/E Aerospace: getting out while the getting is good?
By Scott Hamilton
Oct. 24, 2016, © Leeham Co.: An announcement Sunday by supplier Rockwell Collins (NYSE:COL) that it will acquire B/E Aerospace (NYSE: BEAV) for $6.5bn caught analysts by surprise. The price tag rises to $8.3bn when assumption of BEAV’s debt is included.
The surprise is not so much BEAV is selling itself. A few years ago, BEAV sold of one of its division and analysts since then believed an exit strategy was underway for the principal owners of the company.
The surprise is that the buyer is Rockwell, a supplier that has little in common with BEAV. A slide from Rockwell’s own investor presentation Sunday illustrates the point.
Rockwell will have an investors’ call Monday at 0830 EDT to further explain the merger.
Bjorn’s Corner: The Engine challenge
By Bjorn Fehrm
October 21, 2016, ©. Leeham Co: In our Corners on East bloc aeronautical industries, we could see that the hardest part to master in a new civilian airliner is the engine.
Both new airliners from Russia and China (Irkut MC-21 and COMAC C919) start their lives with Western engines.
Why is this so? What are the challenges that make engines harder to create than aircraft?

We will spend several Corners on the main reasons that airliner engines are harder to do than aircraft. Read more
