TU-330 layout
Aircraft Design Bureaus of CIS are currently busy with building of transport aircraft of new generation.


TU-330 a/c is provided with government support by way of Government Resolution of the RF No.369 of 23 April, 1994 “On building of mid-class transport aircraft TU-330”. Russian Government showed comprehensive understanding of the situation in the field of air cargo transportation. According to GosNIIGA 2/3 of mid-range aircraft total cargo turnover falls in flight range of 1000 to 4000 km. From the other hand exactly this area is the most critical since main mid-range aircraft An-12 being currently in operation is now intensively written off because its service life is served out.
This principle was also used when designing a special purpose middle-class cargo aircraft TU-330 which is being developed on the basis of a large scientific, technical and production work already done in Russian industry during development and manufacturing of passenger airliners of the third generation TU-204, TU-214 and TU-334.



TU-330 aircraft is made as a monoplane with large aspect ration high wing provided with winglets. Two turbojet high by-pass ratio engines PS-90A are installed on pylons under wings. Tail is of usual layout with adjustable stabilizer and elevators. Landing gear is composed of six fully independent undercarriages - two brake wheels per each; and with one nose controlled undercarriage with two wheels. The landing gear provides operation from paved and unpaved RWY.

MAIN PERFORMANCE OF TU-330 AIRCRAFT
1. Maximal payload - 35 t
2. Cruising speed - 800-850 km/h
3. Maximal cruising altitude - 11000 m
4. Servicing flight range with payload of 30 t when operating from concrete airfields with RWY length 2200 m - 138-140
5. Flight fuel consumption for servicing range with max payload - 3000 km
GEOMETRIC CHARACTERISTICS OF TU-330 AIRCRAFT
1. Length - 42.0 m
2. Wing span - 43.5 m
3. Height - 14.0 m
4. Wing area - 195.5 m2

TU-330 A/C CARGO CABIN DIMENSIONS
1. Length - 19.5 m (23.5 m including ramp)
2. Width (on the floor) - 4.0 m
3. Height - 4.0 m (3.55 m under wing center section)
The aircraft is capable to operate on routs of 5600 km with payload of 20 t and for 3000 km range with payload of 30 t. Thus this aircraft can fully replace AN-12 a/c and partially IL-76 a/c on mid-range flights.


TU-330 a/c has been optimized to operate on mid-range routes wherein the aircraft has the best prime cost parameters.


Further important advantage of TU-330 a/c is a deep (up to 75%) commonality with certified passenger aircraft TU-204 and TU-214. Wide application on TU-330 aircraft the TU-204 and TU-214 a/c units and components tried out and tested during operation made it possible to cut down sharply the dates of research and development works and certification process for TU-330 a/c.


The aircraft will have more favorable market situation especially among airlines which operate TU-204 and TU-214 a/c. It also can be provided with engines of foreign production – Rolls-Royce, Pratt Whitney - which will facilitate its realization in western markets.


Airlines of Eastern and Western Europe, Middle East and South-East Asia express their keen interest in TU-330 a/c project during International Airshows.


TU-330 a/c Program has started the way of real solution of transportation problems in Russia regarding mass cargo transportation within the shortest periods and at the lowest expenses. In this case by its technical level TU-330 a/c is comparable with Passenger aircraft of new generation TU-204, TU-214. and IL-96M.
TU-330 a/c has no limitation regarding flight conditions and can be operated in any

climatic zone, under visual and instrument meteorological conditions, in day and night, at different altitudes; the aircraft can be operated from available airfields (including unpaved RWY). The aircraft does not require a new ground infrastructure since loading and unloading operations are performed autonomously by crew supported by aircraft transportation and cargo cabin equipment. High effective engines PS-90A used on the aircraft meet the most strict international noise level requirements and substantially do not affect environment.


TU-330 a/c aerodynamic cleanness is mainly defined by use of high-effective wing and power unit tested and tried out during long-term investigations carried out by TsAGI, TsIAM and LII scientists on TU-204, TU-214 and IL-96M a/c.


This will make the TU-330 a/c to be the most cost effective cargo aircraft in the world with specific fuel consumption of less than 140 g/g km. For example, the TU-330 a/c fuel consumption per one hour is two times less that of cargo IL-96 a/c being currently in operation.


For typical range of mid-class transport a/c non-stop flight equal to 1700 km and basing on existing network of cargo airlines (according to Gos NII GA estimation) the TU-330 a/c showed to be substantially two times more cost effective than that of Russian cargo medium capacity a/c An-12 by absolute fuel consumption per transport unit.


The most cost-effective operation of TU-330 a/c turned to be when making mass cargo carriage for 1500 – 4500 km range. In 85% of the events weight of goods to be transported does not exceed 25 t. In this case take-off weight of the a/c is less than 100 t which allows to use for take-off and landing RWY not exceeding 1800 m and typical transport task (20 t of cargo to be carried for 3000 km) can be solved in 75% of the events. In this case the landing gear design can provide operation from soft-surface paved RWY and from unpaved RWY with runway sub-soil strength about 7 kgf/cm2.


It does not mean that TU-330 a/c capabilities are limited by said figures. Maximal weight cargo carried by said a/c will make 35 t; typical cargo of 20 t weight the a/c is capable to carry for the range of 5 600 km; field length required being 2 200 m.


Cargo compartment dimensions make it possible to receive substantially entire range of cargo containers and pallets, packaged and long goods, most types of motor cars and other wheel and caterpillar machinery and also to carry military equipment and armament and to provide people and goods dropping.
Special attention is paid to improvement of a/c operational characteristics, in the first place of ground maintenance. In this case of great importance is unification with mass passenger aircraft TU-204 and TU-214: substantially the same set of spare parts, similarity of technological operation of TU-204, TU-214 and TU-330 a/c ground maintenance and overhaul can significantly facilitate its operation by airlines. Specific expenses for TU-30 a/c maintenance meet future world level.


Thus TU-330 a/c is a really mass medium-capacity which maximally meets Russian demands of main cargo flow with the most fuel and transportation effectiveness. In the first place Russia needs exactly such cheap and simple aircraft capable to optimal cargo re-distribution between various types of transport taking certain amount of cargo from motor, rail and river transport.


None of cargo aircraft built in the past and being built now is optimized by main parameters to provide mass transportation in Russia and can compete with flexible TU-330 a/c.


One more design particularity of the aircraft should be mentioned – its engines can operate on LNG (liquefied natural gas). This prospective trend of aviation wherein Tupolev Design Bureau is absolute leader is especially actual for Russia having rich reserves of natural gas, especially in northern regions.


Activities on TU-330 a/c are performed in view of building a baseline model with structural elements which allow conversion into aircraft of different purposes and use LNG as a fuel.


According to Customer request the aircraft can be produced in following versions: refueler, ambulance a/c, hospital a/c, ecological monitoring a/c, a/c for hunting industry and fishery, icing survey, a/c for initial exploration under extraordinary conditions, fire fighting a/c, tanker to carry liquefied natural gas, repeater a/c, special administrative a/c (cabin +two motor cars) etc.
