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.Â
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 AerospaceÂ
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.
