Many people talk about the Airbus’s new “NEO” family, but what exactly is it? You have probably seen the easyJet onboard advertisement, giving you a few facts about how it cuts down on noise and fuel emissions, but let’s face it, there’s so much more to the plane than just the name…
- How Does It Cut Down On Noise? The A320NEO uses a pair of Pratt and Whitney PW1100G-JM turbofan engines. Which are half as quite as its predecessor, the CFM56, which can reach up to 95.2 dB. Anything above 85dB, with enough exposure to the sound, is loud enough to cause temporary, or permanent hearing loss. The PW1100G-JM is about 15dB, which is roughly 80dB, better for the mechanics working around the engine, and the people that may live close to a flight path and hate the sound…
- How Does It Cut Down On Fuel Emmisions? The PW1100G-JM “PurePower” engine has a margin of 50% to CAEP/6,( Local Air Quality and ICAO Engine Emissions Standards), so for every 1Kg of fuel burned, there must be no more than 3160g of CO2, and 15g of NOx*. Meaning that the PW1100G-JM engine outputs about 1580g of CO2. The engine also has a margin of 35% to CAEP/8, which means it has about 7.5g of NOx per 1KG of fuel burned
- What Does NEO Stand For? NEO stands, quite simply, for “New Engine Option” In fact, we should now be calling the aircraft that do not have “NEO” in the name, CEO, which stands for “Current Engine Option”
- Which Airline Owns The Most NEOs? You may think that it is easyJet, or Lufthansa (Lufthansa where the “first to fly NEO”) But no, it is in fact, AirAsia. AirAsia in June 2011, put in 304 orders for the A320NEO, and 100 orders for the A321NEO, and as of the 30th of June, 2017, have received 8 A320NEOs. Currently, it is IndiGo who possess the most NEOs, with 22 a320NEOs
- What Makes The NEO So Special? Apart from the fact that it’s better for the environment, and that it less noisy, it is also incredibly fuel efficient along with the wingtips. The fuel efficiency of an aircraft is based upon three factors, the drag contributed by the airframe, fuselage, wings, and induced drag from aerodynamic effects such as wing tip vortices, which is why the new A380 has the new wingtips. It also is made up of less parts, meaning that it is easier for the maintenance crew, and less resources are used.
