The United Engine Corporation (UEC) reported on the progress of testing the latest PD-8 aircraft engine. The total operating time of prototypes exceeded 6,100 hours: this is higher than the performance of comparable engines at the same stage of development, Perviy Technicheskiy was told in the UEC press service.
This year, Superjets with PD-8s have made long flights to Arkhangelsk, as well as to India and back. In total, three aircraft are participating in the certification test program, which have already made more than 140 flights. In recent months, they have successfully confirmed gas-dynamic stability, rate of climb, operation in natural icing conditions, reaching a large angle of attack, and the level of noise in the cabin.
Operating time is one of the main indicators in preparing an engine for certification. It includes flight tests in various modes, factory checks, and testing on a flying laboratory.
PD-8 is a Russian two-spool turbofan engine created at the UEC-Saturn Rybinsk enterprise. It is designed for the short-haul Superjet and the Be-200 amphibious aircraft. The engine was developed in broad cooperation with UEC enterprises using new domestic materials and components.
