Honored Pilot Criticized the Re-equipment of Superjet with PD-8 Engines: A New Aircraft Needs to Be Built

Re-engining the Superjet-100 with domestic PD-8 engines instead of foreign SaM146 seems to be a completely unprofitable undertaking, as the aircraft will have to be completely redesigned. This opinion was expressed in an interview with "The First Technical" by Honored Test Pilot, Hero of Russia Alexander Garnaev.

According to him, the experimental design work will affect the power component of the airframe and the load-bearing structure of the aircraft.

The specialist noted that after the work, the aircraft with PD-8 will have to undergo a full cycle of certification tests, as a completely new aircraft.

Aviation expert Andrei Velichko explained to "The First Technical" that re-engining the Superjet with PD-8 is possible, but everything comes down to the issue of funding for the work.

Main technical characteristics of PD-8:

• Total pressure ratio - 28

• Thrust - 8,056 kgf (at maximum take-off mode)

• Specific fuel consumption - 0.61 kg/kgf·h (in cruising mode)

• Length (with mixer) - 3,589 mm

• Fan diameter - 1,228 mm

It will also be necessary to significantly increase the production of PD-8 engines, which are also intended for import-substituted SJ-100s and Be-200 amphibians. In addition, these power plants were also planned to be installed on business jets based on the revived Tu-324.
