Light all-purpose transport and VIP aircraft Antonov-74 is designed for medium-hall airlines. Its reliability has been proved by the ability of different models to operate in all possible weather conditions and climates: it can operate at -60С and +45С as well as in high-mountain regions.
Turbofan engines D-36 of 2A and 3A series used in the aircraft are suitable for long-life operation, they are fuel efficient and comply with ICAO noise and emission certification standards.
Advantages of the aircraft:
- two powerful engines 6500 kgf thrust each and highly mechanized wing allow to shorten takeoff and landing and perform flights involving curved and steep approaches, which is of great significance when operating on short runways or runways with ice surface;
- high trafficability of landing gear and overwing engines located high above the ground make it possible to operate the airplane on wet, snow-covered runways with unpaved, sodded, peas and ice surface;
- multiple redundancy of principal systems and high manoeuvrability both in the air and on land make Antonov-74 aircraft highly competitive in operating in extreme environmental conditions and emergency situations.
Design Specifications
Overwing Engines:
- increase the airflow by 30 % thus boosting lift due to the Coandă effect;
- together with powerful high-lift devices reduce the required length of runway by 1.6-1.8 times;
- are protected from penetration of different particles (like r pebbles, ground pieces, ice, dust, etc.) during takeoff and landing.
- tricycle landing gear with low-pressure tires;
- highly mechanized wings (slats, flaps, spoilers and other elements increase the wing area and wing curve much more than in other aircraft models);
- possibility of self-location up to 100 hours per month;
- cargo hatch abaft;
- two-position ramp;
- cargo handling equipment.
The high thrust-to-weight ratio allows this airplane to continue its flight at a height of 8000 meters at the maximum payload with one engine inoperative.
Technical Data:
- Life time 40 000 hrs, 20 000 landings, 40 years;
- Line maintenance makes after 300 ± 30 hrs, there are 12 line maintenance forms;
- Moreover, there are Heavy forms (equal C-Check), first heavy form makes after 4 years, from form 1 to form 2 — 6 years, from form 2 to form 3 – 4 years, from form 2 to form 3 – 6 years.
