The ATR 72 is a twin-engine turboprop, short-haul regional airliner developed and produced in France and Italy by aircraft manufacturer ATR. The number "72" in its name is derived from the aircraft's typical standard seating capacity of 72 passengers. The ATR 72 has also been used as a corporate transport, cargo aircraft, and maritime patrol ...
The engine series will premiere as the standard powerplant on all new ATR 42 and ATR 72 aircraft, with a launch order from Air Corsica using the PW127XT-M engine model. The PW127XT-N variant, which is designed for the ATR 72-600, has the same mechanical power rating as the PW127XT-M but has a higher thermodynamic power rating. [7]
The ATR 72 is a twin-engine turboprop, short-haul regional airliner developed and produced in France and Italy by aircraft manufacturer ATR (Aerei da Trasporto Regionale or Avions de transport régional), a joint venture formed by French aerospace company Aérospatiale (now Airbus) and Italian aviation conglomerate Aeritalia (now Leonardo S.p.A ...
The 900th aircraft, an ATR 72-500, was delivered to Brazilian airline TRIP Linhas Aéreas on 10 September 2010. [20] During 2011, Royal Air Maroc took delivery of the first ATR 72-600. The 1,000th aircraft was delivered to Spain's Air Nostrum on May 3, 2012. [21] On 15 June 2015, Japan Air Commuter signed a contract for ATR's 1,500th aircraft.
The causes that led the French-built ATR-72 turboprop plane operated by regional carrier Voepass to plunge in a flat spin to the ground have yet to be established.
For this reason turboprop engines are not commonly used on aircraft [4] [5] [6] that fly faster than 0.6–0.7 Mach, [7] with some exceptions such as the Tupolev Tu-95. However, propfan engines, which are very similar to turboprop engines, can cruise at flight speeds approaching 0.75 Mach. To maintain propeller efficiency across a wide range of ...
This is the case on many large aircraft such as the 747, C-17, KC-10, etc. If you are on an aircraft and you hear the engines increasing in power after landing, it is usually because the thrust reversers are deployed. The engines are not actually spinning in reverse, as the term may lead you to believe.
In addition, both ATR-42 and ATR-72 aircraft had their deicing boots modified to extend the boot area to reach back to 12.5 % of the chord. Previously, they had extended only to 5 % and 7 %, respectively. In theory, that should solve the problem of the tendency of ice ridge formation at the 9% chord position of those obsolete sharp-stall airfoils.
