CIAM completed the next stage of engineering testing to support PD-14 engine certification

The Central Institute of Aviation Motors after P.I. Baranov (part of National Research Center «Zhukovsky Institute») has successfully completed the next stage of the ground testing of the Russian PD-14 engine for the new short- and medium-haul passenger aircraft MS-21. The goal of the testing was to experimentally determine the impenetrability of the fan casing if the blade breaks.

CIAM's test stand T14-01B underwent major re-engineering to enable the full-scale testing of the PD-14 engine fan. Extensive work was conducted for a year to revamp the stand’s armored chamber to enable the testing of a high by-pass turbofan engine fan module, including the total replacement of the vacuum system, the installation of a new measurement system, and the provision of equipment for high-speed video recording of the destruction process.

The "dress rehearsal" in the process of preparation was preliminary testing, simulating blade breaking at the engine's operating speed. The testing proved the functionality of the re-engineered test stand systems and structures developed by CIAM specifically for testing the PD-14 engine fan.

The test results established the absence of non-localized fan casing breakdown; the trajectories of the broken blade fragments, the rotor behavior after blade breaking, as well as the condition of the adjacent blades hit by the broken blade were recorded.

The tests proved the impenetrability of the engine fan casing under the expected operating conditions.

The next stage of ground testing of the PD-14 engine fan on the T14-01B stand will involve a single bird-strike resistance test. The design and construction work for the new test stand process systems and equipment is currently underway to enable this testing.

CIAM has the unique experimental facilities to provide research support and conduct the special testing necessary for PD-14 engine development. Thus, integrated testing of the full-scale combustion chamber of the 5th generation engine was conducted at the UV-13 and Ts5-2 test stands; icing tests of a model of the engine nacelle air intake were conducted on the Ts-2 stand; and a number of tests of a scale model of the fan with S180-2 booster stages were conducted on the Ts-3A stand. A large number of strength tests are also being carried out.
