Critical altitude | 11,000 m |
Engine starting critical altitude: |
on the ground | up to 5,000 m |
in the air | up to 8,000 m |
D-36 engines and their modifications are highly reliable and economic. Among their main advantages are low specific fuel consumption, ability to take off in the extreme weather conditions, "hot and high" characteristics. These engines are simple to service and repair because of their modular construction. |
The exhaust section of the bypass duct is arranged to make it possible to equip the engine with a thrust reverser. |
Modifications |
Designers intended to create a family of aircraft based on the An-72/74P model. These airplanes were supposed to be designed for a variety of specific tasks, i.e. An-72PS for sea patrols, anti-submarine aircraft with a magnetic meter, firefighting aircraft and even floatplane with boat fuselage and underwing floats. There were also plans to create a ship airplane for aircraft carriers with a folding wing consoles. However, none of these modifications were built.
