15 January 2016, ©. Leeham Co: Last week we looked back on what happened in 2015 on the airframe front. We finish the retrospective by looking at what turbofan engine technology came to market in 2015. New engine technology is vital, as it is on the engine side that the quest for higher fuel efficiency has the largest successes.
While advances on the airframe side might bring an additional 5% per generation, the engines typically increase their efficiency per new generation with up to three times that value. Fuel efficiency per delivered thrust unit was improved with a whopping 15% over the engine it replaces for the Pratt & Whitney Geared Turbofan (PW GTF). It was certified for use on the Airbus A320neo in Q4 2015
The competing CFM LEAP-1A shall deliver the same improvement level to the A320neo once it is certified in the summer of this year. This engine has a smaller sister that started ground tests last year, the LEAP-1B, which is developed for the Boeing 737 MAX series.
The engine that is easily forgotten is the Rolls Royce Trent XWB. It entered service on the Airbus A350-900 during the year. It brings an improvement level of around 10% compared to the engines of the aircraft that the A350 replaces (Airbus A340/A330ceo and Boeing’s 777-200 range).

Introduction
01 Feb 2015: Six years ago Tom Enders, then-CEO for Airbus (when the parent was named EADS), threatened to stop the A400M project. He then played hardball to get eight European states to understand they had to pay 5bn Euro more or get no plane. Airbus existence could be threatened by a project that its management when the program was launch (CEO Jean Pierson) did not want but that the politicians convinced Pierson’s successor, Noel Forgeard, to do.
Now Tom Enders is CEO of Airbus Group and has to apologize to the same governments that he struck a deal with then to finish the project if Airbus got the money and a consent to three years of delays. Now Airbus can no longer fulfill the terms and the airplane is still falling short of performance specifications. Deliveries have been delayed further and promised capabilities will be delivered later than said. Like then, heads are rolling at Airbus and tighter control is being applied.
