TsAGI scientists make preparations for model tests of the MC-21 with the PD-14
4 September 2017
Specialists of the Zhukovsky Central AeroHydrodynamic Institute (TsAGI, a member of the National Research Center" Institute named after N.E.Zhukovsky") are preparing to study a model of the MC-21 with PD-14 engines.
The scientists will define aerodynamic characteristics of the platform in configuration with the power unit after measurements by electromechanical balances. The testing will take place at TsAGI’s transonic wind tunnel and include work at high angles of attack. It will allow simulation in both takeoff and landing modes.
TsAGI specialists created a model of the MC-21 for the testing. According to research results, the scientists will be able to identify aero-coefficients vs. Mach numbers and angles of attack.
The PD-14 is a promising turbojet engine (lead developer — JSC “UEC-Aviadvigatel”), the main feature being the use of a unified generator. The PD-14 is one of the two engines for the MC-21 produced by PJSC “Irkut,” the second being the PW-1400G.
