TsAGI experienced a promising model aircraft frigate Ekodzhet

The aircraft "Frigate Ekodzhet"  —  a new generation of wide-body passenger aircraft to be operated on routes near-and medium-range (up to 4500 km). The distinguishing feature of this aircraft fuselage geometry is a cross section in a horizontal ellipse.

Central Aerohydrodynamic Institute Zhukovsky (TsAGI) experienced a promising model aircraft "Frigate Ekodzhet."

The experts of aerodynamics TSAGI tested the cruise configuration of the model aircraft "Frigate Ekodzhet." Client work — JSC "Russian Aviation Consortium." The studies were conducted in a transonic wind tunnel T-106 TsAGI.

 
Tests have shown that the developed aerodynamic design with a lifting fuselage and wing of the large relative thickness achieves the design speed is cruising at a favorable character of the bearing and torque characteristics. The experiment demonstrated the ability to achieve the claimed level of aerodynamic qualities.

Data obtained from the experiment will be used for further aircraft design "Frigate Ekodzhet".

In 2012, the planned testing of the model "Frigate Ekodzhet" in the subsonic wind tunnel T-102 TsAGI. Aerodynamics of TsAGI will determine the characteristics of the aircraft on takeoff and landing in the longitudinal and lateral channels, including ground effects.

The aircraft "Frigate Ekodzhet" represents a new generation of wide-body passenger aircraft to be operated on routes near-and medium-range (up to 4500 km). The distinguishing feature of this aircraft fuselage geometry is a cross section in a horizontal ellipse.

Finding the optimal cross-section fuselage was conducted in the direction of ensuring the minimum size of the aircraft provided that they contain the fuselage 300-350 passengers in a three showrooms with three major passes.

The program "Frigate Ekodzhet" is to create a globally competitive family of commercial aircraft, integral performance indicators which 15-20 per cent will exceed the level achieved by the civil aviation technology at present.
