Chinski MA60 - Modem Ark 60

[polar_khan]

Czy ktos slyszal o Chinskim MA60 jest to turboprop produkcji krajowej mogac
pomiescic 50-60pax. Czy ma ktos jakies konkretne informacje o nim? Chodzi mi
czy maja zamiar sprzedawac go w EU np.? Z tego co wiem kosztuje okolo 11$USD
Czyli jeszcze tanszy od ATR72-500 Ktory chodzi po 14-18$USD...Tylko ze chyba
nie zaduzo osob ma zaufanie do samolotow czysto Chinskiej produkcji...

Oto kilka zrodel...po angielsku przeprasam...

According to the requirement of CCAR-25 and FAR-25,XI'AN AIRCRAFT COMPANY has
designed and developed a short-medium range aircraft MA60(Modem Ark 60)that is
a twin turbo-prop multi-role aircraft with a commuter services as its primary
roles. It has a maximum take-off weight of 21,800kg and a seating capacity of
up to 60 passengers in the high density version. With a pressurized cabin, the
aircraft possesses the level of comfort comparable to trunk aircraft. The
aircraft is well-suited to fulfil a variety of other roles such as executive
transport, light package carrier, remote sensing and aerial research services,
coast guard, border patrol, air ambulance and other community services, etc.

MA60 is a state-of-art design that can be a cost-effective solution in a wide
variety of roles.

The aircraft has the following features:
1. All weather,day/night night capability
2. Pressurized cabin
3. Operability from semi-prepared runways
4. Two-man operation flight deck
5. Operability from high altitude airfields on hot days with little or no
compromise on take-off weight
6. Cabin comfort level matching with that of trunk aircraft

POWER PLANT

MA60 is powered by two Pratt and Whitney Canada PW-127J engines driving two
247F-33.962m diameter 4 bladed propellers supplied by Hamilton Standard, USA.
The engines are mounted on wings. The power plant has the following features:
·Light weight
·Three axles free turbine engine
·EEC control system supplies accurate control and monitoring
·β control system
·Low fuel consumption, 30% lower than normal technology engine
·Max. Take-of power of 2,750SHP
·Power from free turbine is transmitted to the propeller through a reduction
gear box.
·propellers are constant speed, variable pitch (feathering to reverse)and auto
synchronized One turbo generator GTCP36-150,made by Honeywell, USA, as APU
·Air conditioning on the ground to improve the cabin environment
·Ground electric power supply and starting engines

FUEL SYSTEM

·Two integral wing fuel tanks (two groups)and two bladder-type tanks with
usable capacity of 5,200 liters. Single point pressure refueling offered
·Gravity reading is available
·Normal fuel supply by injection pumps
·Electrical pumps supply the fuel under the emergency condition
·Fuel can also be supplied by gravity now
·Electrically operated cross-feed valve ensures supply of fuel to a single
engine from both tanks or to both engines from single tank
·Capacitance gauging show contents of each wing tank and total contents
·Rate of fuel indicator for each engine

·Balanced take-off field length (MTOW) Sea level，ISA: 1,300m
H=1,219m,ISA+10℃: 1,600m
·Landing field length required (MLW) Dry runway，at destination Sea level，ISA:
1,400m
·Single-engine net ceiling (95%MTOW) ISA:3,200m
·Maximum operational cruise altitude: 7,620m
·Max cruising speed (TAS) 96%MTOW,ISA H=5486 450km/h STAGE PERFORMANCE ISA，
still air，Cruise altitude 6,096m,IFR reserves

Structure designed for 30,000FH,25000 take-off/landings,or 25 calendar years
servicing life.

Reliability

Achieving a high degree of reliability has been one of the major goals in the
design and this has resulted in selecting systems, sub-systems and other
equipment which are well proven, certificated and have established a good track
record of reliability. For example, the PW-127family of engines has estab1ished
over the years a reputation for extremely reliable engines. The integrated
digital avionics system has inherently a high level of reliability (MTBF is
8,000-12,000 flight hours)with practically no maintenance-intensive component
which might wear out or break down. Redundancy has been built into all critical
areas so that the overall system reliability is high.

Maintainability and Availability

Attention has been given right from the beginning for easy maintenance and thus
to increase aircraft dispatch rate.
Equipment needing inspection/maintenance have been provided with the easy
access, the PW-127 engine is of modular construction and thus easy to maintain.
Furthermore, the cowling is designed in such a way that the front and rear ends
are large and panels to have full access to servicing points on engine and
aircraft accessories. The avionics equipment, hydraulic system and the air
conditioning system bays, all have large doors for easy assess.

Zdaje się, że MA60 jest rozwinięciem Y7, czyli licencyjnej chińskiej wersji
rosyjskiego An-24/26. Trudno powiedzieć, co on jest wart.
