Introduction
Feb. 29, 2016, ©. Leeham Co: In two articles we have been looking at the new Russian single-aisle aircraft, Irkut MC-21from United Aircraft. Now it’s time to analyze the new Russian engine, PD-14, which is offered as an alternative to the base engine for the aircraft, the Pratt & Whitney PW1400G. 
Summary:
- The PD-14 is a new engine designed by the Aviadvigatel company, a merger of the Soloviev design bureau with the Perm engine company.
- PD-14 is a modern 31klbf design aimed at several Russian aircraft, the first being the MC-21.
- The technology and performance of the PD-14 engine are approaching its Western counterparts, Pratt & Whitney PW1400G and LEAP-1A, but not quite reaching their level. We go through where it differs. Read more
Bjorn’s Corner: Flight tests
By Bjorn Fehrm
19 February 2016, ©. Leeham Co: Last week I described how Mitsubishi Aircraft Corporation (MAC) issued a press release on Christmas day communicating MAC would be doing structural reinforcements on their test airframes before continuing flight testing. MAC was perhaps overzealous when informing the world that they would do minor reinforcements to two ribs and a few stub spars in order to pass Ultimate strength tests for the aircraft.
I rightfully thought this is the Japanese culture at play; there must not be a big problem behind it.
There was one more area of that press release that intrigued me. Here what it said: “The first flight and the subsequent flight tests have confirmed the basic characteristics to be satisfactory. However, we also have recognized several issues as we attempt to accelerate our development.”
Time to decrypt this as well and compare to what has become standard industry practice.

Feb. 25, 2016: Embraer rolled out its E190-E2 to a series of fly-bys of EMB aircraft ranging from a crop duster to the KC-390, hundreds of invited guests and media and thousands of its employees.
Here are some photos from the rollout.

Luis Carlos Affonso, senior vice president of Embraer Commercial Aircraft, announced the change during media briefings in advance of the E190-E2 rollout tomorrow at the EMB plant here.
Airbus Group 2015 results: A330 increase to seven per month
By Bjorn Fehrm
24 February 2016, ©. Leeham Co: Airbus will increase the production rate of the A330
from six per month to seven beginning next year, it was announced today. The move comes after reducing the rate from 10 to nine and then to six per month as demand fell for the A330ceo ahead of the development of the A330neo.
Strong sales of the ceo resulted in the about-face to increase the rate.
The news came from the Airbus Group financial results for full year 2015 today in London.
In all other aspects it was a year of solid execution with revenue up 6% to €64.5bn. Profits stayed flat at €4bn despite record deliveries; the A350 and A400M ramp-ups are costly exercises.

Introduction
Feb. 24, 2016, ©. Leeham Co: Two weeks ago we started our analysis of the new Russian single aisle aircraft, United Aircraft’s Irkut MC-21. We looked at key design features and compared these to the Airbus A320.
We also analyzed the passenger capacity where we found that the model which will start flight testing, the MC-21-300, has a capacity between the A320 and the A321. The closest aircraft in capacity and performance in the MC-21 lineup versus the competition would be the MC-21-200 and A320neo.
We have therefore decided to do our efficiency analysis between these variants.
Summary:
- The MC-21 has a wider fuselage than the A320. This is a positive as it allows passengers to pass each other in the aisle of the cabin.
- The drawback of the wider fuselage is a bit higher aircraft drag.
- Coupled with a lower wing aspect ratio, the lighter MC-21 cannot open a fuel consumption advantage over the A320neo, despite being a more modern design.
