The first start of the certification-profile D-436-148FM turbofan
The first start of the certification-profile D-436-148FM turbofan engine was made on December 9th, 2015.
This was preceded by a large scope of stand experimentation and analytical research into optimization of the engine structure to support specified requirements.
The D-436-148FM is intended to power the An-178 short – haul military transport aircraft with carrying capacity of about 18 tons. The engine features higher thrust values at all operating conditions, and improved emission characteristics, compared to the basic D-436-148 turbofan.
To reduce the noise, efficient sound-absorbing structures are integrated into the engine profile.
