• CFM56: The Best-Selling Aircraft Engine in the World

  

  CFM International’s CFM56 is the best-selling aircraft engine in the world. A few days ago, the 30 000th one rolled off the assembly line. Let’s take a closer look at this Franco-American success story between Safran Aircraft Engines and General Electric.
   

  

• Safran’s subsidiaries acquire new names

  

  In order to become more legible and visible in their various markets the ten companies in the Safran Group officially changed their names on 19 May. Snecma, for example becomes Safran Aircraft Engines.
   

  

• Jet engines: why evermore larger fans?

  

  On commercial aircraft in the last decade, the trend has been toward wider jet engines with diameters increased by 6 to 20 inches (15 to 50 cm). Why? To consume and pollute less.
   

  

• First series-production LEAP engines delivered to Airbus

  

  The first two LEAP production engines for the A320neo were delivered on 15 April to Airbus. The first plane equipped with this engine should enter service sometime in June.
   

  

• Engine location: below or above the wings?

  

  Today, most commercial aircraft are equipped with engines under the wings, unlike the 1970’s VFW-Fokker 614, which had them above. For what reasons? We went to find out from engine manufacturer Snecma, a Safran Group subsidiary.
   

  

• The LEAP will pulsate at Snecma

  

  By 2020, Snecma will be producing 1,500 units of their new LEAP engine per year. To do this, the engine ma nufacturer will integrate high-tech assembly lines at their Villaroche (near Paris) premises.
   

  

• What is a combat aircraft’s engine temperature ?

  

  High temperatures have always been one of the major challenges in the manufacture of jet engines. But what is the temperature inside an engine such as the M88 ?
   

  

• On take-off, at what speed does an aircraft engine fan turn?

  

  An aircraft engine fan rotates at such a speed that it can suck in anything that approaches it. To find out how fast a fan turns on take-off, we asked the engine manufacturer Snecma (Safran Group).
   

  

• LEAP makes first flight on the A320neo

  

  On 19 May, Airbus conducted the first flight of an A320neo equipped with LEAP turbofan engines. Developed by CFM International, this engine marks a technological breakaway from the CFM56.
   

  

• JPB Système : the specialist in Self-Locking Solutions

  

  JPB Système designs self-locking solutions for the major engine and airframe manufacturers. The SME has been developing and selling its technology since the company was created in 1995. We review the beginnings of this success story.
   

  

• Just how does a jet engine work ?

  

  The essential element of any vehicle lies in its capacity to create energy for it to move. The following is an overview of the function of a new high-bypass turbofan engine called the LEAP, developed by CFM International.
   

  

• When new technology arrives at the factory...

  

  ?To improve product design, manufacturing procedures, and controls, new technological tools are emerging, such as here on the premises of the engine manufacturer Snecma (Safran Group), in the Paris suburbs. Touchpads, robots, electronic wrenches, we took a quick look at the innovations in this part of the aviation industry...
   

  

• Snecma developing the engine of the future

  

  Aiming at a reduction of 30% in fuel consumption of aircraft, Snecma (Safran Group) is developing a revolutionary concept : Open Rotor. An engine that will mark a technological breakthrough around 2030.
