Russia's United Aircraft Corporation has unveiled the main system suppliers for the planned three-member MS-21 twin-jet family.

Contractors were selected following international tenders invited last year by airframer Irkut, which is steering the project and will act as a system integrator.

The bidding commission has awarded the following Russian and Western firms with mandates to supply 'first-level' systems:

  • Landing-gear: Hydromash
  • Auxiliary power unit and wing de-icing systems: Hamilton Sundstrand
  • Air conditioning: NPO Nauka, in conjunction with Hamilton Sundstrand
  • Fire protection system: Kidde Technologies' L'Hotelier and Hamilton Sundstrand
  • Hydraulic controls: Eaton, with 50% component production at Russian firms Voskhod, Teploobmennik, Tekhpribor and Znamya.

Irkut has selected Zodiac's C&D supply cabin interiors, as well as its Intertechnique division for the fuel management and oxygen system.

Intertechnique will also join with Hamilton Sundstrand on a neutral gas system, while Zodiac subsidiary ECE and Hamilton Sundstrand are to provide electrical systems.

The bidding commission has also shortlisted proposals from the following firms for further evaluation:

  • Engines: Pratt & Whitney and Rolls-Royce
  • Avionics: Rockwell Collins and Avionika
  • Integrated control system: Aviapribor Holding, along with Goodrich and Moog, and Liebherr Aerospace

Irkut is planning to complete selecting contractors to supply these three systems by 1 November.

Its MS-21 will comprise three models, the first of which will be the 150-seat MS-21-200. This will be followed by the -300 and -400 with 181 and 212 seats respectively. Irkut expects the first aircraft to be operational by 2016.
