MC-21

The introduction of innovative engineering concepts is poised to garner the MC-21 the best performance rating among airplanes of its class. The MC-21 will stand out from its counterparts due to its: reduced empty weight achieved through the use of composite materials and advanced metal alloys, combined with the introduction of next-generation airborne systems; more refined aerodynamics; and the use of an advanced engine. These and other improvements will enable a substantial reduction in fuel consumption compared to similar airplanes.

A customer-focused product development approach was implemented in the MC-21’s design process. It involves the engagement of potential customers in the airplane design process as early as possible in the project.
 

Due to the increased diameter of the MC-21 fuselage, airlines will be able to adjust the “seat width/aisle width” ratio to their needs in an optimal way. Airlines specializing in long-haul transportation will be able to offer passengers more comfort. Charter carriers and low-cost airlines will be able to reduce airport turnaround times due to the wide aisle. The larger fuselage diameter will also enable an increase in baggage rack space and the underfloor baggage compartment area.

Airplanes in the MC-21 family will meet all of the environmental-protection standards expected to be introduced in the future. It was determined that the cumulative level of perceived aircraft noise according to three-point measurements would have a margin of at least 15 EPNdB under the standard of the currently effective ICAO Chapter 4. Engine emission performance should satisfy the requirements of ICAO CAEP 6 by a 50% margin. The MC-21 will release 15-25% fewer CO2 emissions into the atmosphere per passenger seat than other airplanes operated today.

The ultimate operating-cost efficiency, international certification in accordance with the requirements of IAC AR, EASA and FAA, as well as the customized logistics support and supervision throughout service life to be provided under the program, will make this airplane a desirable product – both for Russian and international operators.

The MC-21 offers passengers a unique level of comfort while reducing flight fatigue due to the following features:

• Increased personal space for passengers, including seats near the window.
• Its interior design accommodates all current anthropometric trends towards an increase in passenger height and volume and makes flying comfortable for people with different body types. Its wide aisles facilitate passenger servicing as the walking space is not blocked by service trolleys, providing sufficient space for two passengers to pass freely at once and enabling higher quality service for disabled and physically-challenged customers.
  
• Large overhead baggage racks provide space for additional carry-on baggage.
  
• The level of natural lighting in the cabin is increased due to its large windows and specific interior design.      

The cabin environment has been improved by:      

• reduced cabin noise level;
  
• increased cabin pressure;
  
• installation of an air-humidification system;
  
• use of the latest biological filters;
  
• three-zone climate control system.
