Aircraft was designed by Oleg Konstantinovich Antonov at Kiev for
utility transport
use requiring short field performance.
HA-MKF was manufactured in 1980 by PZL-Mielec in Poland.
Power Plant:
WSK-PZL-Kalisz (Wytwornia Sprzetu Komunikacyjnego-PZL-Kalisz)
Shvetsov ASz-62 IR Geared 9 Cylinder 1823 Cu. In. Radial Engine, rated
at 1000 HP max, driving a 4 blade AW-2 Propeller.
Take-Off Power 1000
HP at 2200 RPM = 110 gallons/hr = 500 litres/hr 5 minutes max.
Rated Power 820 HP
at 2100 RPM
Max. Continuous 738 HP at 2030
RPM
75% Power 615 HP
at 1910 RPM
50% Cruise 410 HP at 1670
RPM = 45 gallons/hr = 200
litres/hr
Propeller Gear Ratio
0.637 to 1 11:16
Normal Operation:
1800 RPM and 800 mm Hg manifold pressure for typical climb.
1600 RPM and 700 mm Hg for typical cruise.
Use 100 Octane Aviation Grade minimum.
Airframe Construction:
The wings are of an unequal span single bay biplane design, all metal
construction, with fabric covering. The wing area is 770 square feet
total. Note: wings have full length leading edge slats and ailerons
droop with flap actuation to provide great STOL performance. The
fuselage is of all-metal stressed skin semi-monocoque construction.
The tail is a braced all metal structure with fabric covering.
Controls:
Ailerons, rudder, and elevators are all manually controlled with
pushrods and cables. Flaps and trim electrically operated. Automatic
leading edge slats provide excellent slow speed safety and high lift.
Landing Gear:
Conventional configuration (tail wheel design) with split axle, long
stroke oleo shock absorbers on the main mounts and a fully castoring and
self centring tail wheel. Brakes are pneumatically operated.
Crew: Normally two pilots, may be
flown single pilot when no passengers are aboard.
Dimensions:
Length = 41 feet, 9 inches; Wing Span = 59 feet, 8 inches; Height
= 13 feet, 2 inches (tail down). Total Wing Lift Area = 256.6 sq.
ft. (156.2 upper, 100.4 lower). Cargo compartment = 13.5 feet long
by 5 feet wide by 5.9 feet tall (398.25 cubic feet). Cargo door
opening - 4.5 feet wide by 5 feet tall.
Weights:
Empty = 7,600 lbs.; Max Take Off = 12,125 lbs.; Max Landing = 11,574
lbs.;
Max fuel = 2,000 lbs. (312 USG);
Oil Qty.= 22 Gallons / 100 litres Max. (13 Gallons minimum to 18 Gallons normal.)
Useful load with max fuel= 2,525 lbs. (3500 lbs with half fuel carried).
Systems:
Compressed Air System: 8 litre (490
Cu.In.) Air Cylinder at 49 bars (711 PSI) maintained
by engine driven AK-50M compressor and AD-50
relief valve. Pressure gauge is on pilot's
left hand console. A pressure reducer supplies 10 bars (145 PSI) for the
main brakes.
The Air Pressure is required for the
pneumatic main wheel brakes, but can be used to
charge the landing gear shock absorbing
oleo-pneumatic struts when dry nitrogen is not available. A fitting is
also available to fill the tires from this system. The 8 litre
air cylinder can also be charged from
appropriate ground support equipment.
Electrical System: 24v DC battery with engine driven
generator to maintain charge.
Voltmeter and Ammeter on Instrument Panel. The 28v DC generator
requires at least 900-1000 RPM to kick in. 36v 3 phase 400hz AC
power, supplied by two converters, is used to power the Russian
Gyroscopic compass, Artificial Horizon and ADF.
CO2 Fire Extinguishing System with automatic fire detector:
Nine fire detectors are located throughout the engine compartment. If
the Fire Warning Lamp light, the CO2 system can be activated by breaking
the safety seal and pushing the button. The CO2 bottle has an
electrically activated pyrotechnic cartridge to release the CO2 into the
collector. Portable CO2 Fire Extinguishers are normally installed in
the cockpit and cabin as well.
Oil Cooling System: The Oil System consists of a 125 litre (33
gal) Max. permitted
22 gal. tank, suction pump and an external Oil Cooler with electrically
controlled shutters.
Use Aeroshell 100 Oil.
PERFORMANCE:
The following data applies to all An-2s except float versions which
have reduced performance and load capacities. Data is based on a typical
weight of 11,600lbs.
Red Line Speed: V-NE 162 kts = 300 Kph
White Line Flaps: V-FE
70 kts = 130 Kph

65 kts = 120 Kph
Maximum Speed: 139kts or 160mph
or 257Kph (120kts / 220Kph more typical)
Economy Cruise Speed: 100kts or 115mph
or 185Km (95kts / 175Kph more typical)
Minimum Speed: 49kts or 56mph
or 90Kph
Take-Off Speed: 43kts or 50mph
or 79Kph (15 degrees of flap).
Landing Speed: 46kts or 53mph
or 85Kph (30 degrees of flap).
