The Frigate Ecojet (in Russian: Фрегат Экоджет, transliterated as Fregat Ekodzhet) is a program for the development of a new wide-body medium haul civil aircraft using new aerodynamic, and design configurations.[1] The project started in 1991 as the Tu-304 under the leadership of Valentin Klimov (then chief designer of Tupolev design bureau) and initially was projected to carry up to 500 passengers. Since 2004 the project is carried out by a new design bureau, led by Valentin Klimov and instituted as a daughter company of Tupolev headed by Valentin Klimov's son, Alexandr Klimov.[2]

The primary goal of the Frigate Ecojet program is the development of a range of new wide body medium-haul aircraft which will be operational by 2018.[3]

In 2015 the company and project engineers were relocated from Moscow to an undisclosed non-EU European country in order to seek flight certification from EASA rather than Russia, this offered savings due to the host country determining certification authority. Russian standards are lower and not yet harmonized with EASA/FAA and if it was based in Russia it would have to repeat at least 30% of qualifying flights for EASA to receive a European flight certification as well as meeting more stringent design standards while if the company was based in an EASA country it could receive EASA and FAA dual certification from a single test program. Sergey Grachev, director of marketing sales for Frigate Ecojet said 'It is impossible to develop and create this kind of aircraft here'. The company still intends to perform first flight in 2018 or 2019 and enter into service in 2021.[4] In moving to Europe the company will also seek to harmonize cockpit design with a competitor to reduce pilot training costs.

In January 2016 the company announced that it had completed wind tunnel trials in Germany in partnership with ThyssenKrupp and that the first 15 (unofficially first 45) would be manufactured and certified in the EU in a location to be announced Feb 2016, believed to be in the short list are Germany, Czech Republic and Slovakia. The performance specifications were also frozen as 352-400 passengers in all economy seating, MTOW 123t, a range of 2340km with a payload of 33.4t and 4500km at 24.7t, a minimum runway length of 2375m and a speed of Mach 0.8.[5]

Initial Technical characteristics[edit]

The new wide body aircraft uses an oval fuselage configuration. The chosen form ensures minimal dimensions for the aircraft with 300-350 passengers in three cabins, three main aisles, no less than 500 mm (20 inches) wide and spaces between seats no less than 810 mm (32 inches). In an all-economy layout, the number of seats can be increased to 400. The aircraft can accommodate 302 passengers in a basic three-class layout (Business Class, Premium Economy and Economy).[6]
