Editing Antonov An-2 (section)

====An-2====
* '''An-2L''' (''Lesozashchita'' – forestry protection) – A fire bomber variant with three cassettes each holding 120 ampoules, containing 1litre (34 fl.oz.) of fire-retardant which were dropped as required. Trials revealed that this system was inefficient and further work was abandoned.<ref name = "An-2"/>
* '''An-2LL''' (''Letayuschaya Laboratoriya'' – flying laboratory) – Any of a number of An-2s used as testbeds for various equipment. One An-2SKh (RA-70547), modified by the State Research Institute of Aircraft Systems. (GosNII AS – ''Gosudarstvennyy Nauchno-Issledovatel'skiy Institut Aviatsionnykh Sistem''), for environmental research, had a lateral observation blister which has often caused the aircraft to be misidentified as an An-2PF.<ref name = "An-2"/>
* '''An-2LV''' (''Lesnoj Vodnyj'' – forest hydroplane) – A firefighting [[waterbomber]].<ref name = "An-2"/>
* '''An-2M''' (Polish:''[samolot] Morski'' – seaplane) – Polish production of the An-2V floatplane, designated An-2M, (not to be confused with the Soviet designation An-2M). Also known as the An-2W.<ref name = "An-2"/>
* '''An-2M''' (''Modifitsirovannyy'' – modified) – The designation An-2M was also used in the USSR for a much improved agricultural crop-sprayer/duster. The An-2M featured an all-duralumin welded and bonded fuselage, lockable tailwheel, enlarged fibre-glass hopper, Shvetsov ASh-62 radial engine with power take off to an auxiliary gearbox to drive the dusting/spraying equipment, an angular fin of increased area and a hermetically sealed cockpit with no access to the cabin/hopper area. The hopper capacity was increased 42% to 2,000 litres (440 Imp.gal.) delivering product through an outlet enlarged to {{cvt|400|mm|in|frac=2}} with dry product being fed to two dusting outlets at the tips of the lower wings. Due to lack of capacity at the Kiev factory and [[WSK-Mielec]] the An-2M was manufactured at DMZ N0.464 (''Dolgoproodnyy Machinery Factory No.464'') to the north of Moscow.<ref name = "An-2"/>
* '''An-2P''' (Polish: ''Pasażerski'' – passenger) (Russian: ''Passazhirskiy'' – passenger) – Soviet and Polish production of a standard passenger variant. Soviet production An-2P's had 10 permanently installed seats in a heated insulated cabin. Polish production aircraft had 12–14 seats, two jump seats for children and a baby cot. A total of 837 An-2P's were built.<ref name = "An-2"/>
* '''An-2P''' (''Protivopozharnij'' – fire-fighting with water) – A fire-fighting aircraft with a dumpable hopper filled with water and/or retardant.<ref name = "An-2"/>
* '''An-2PD-5''' (Polish: ''Pasażerski [samolot] Dyspozycyjny'' – executive aircraft's) – The production version of the 'An-2PD-6', featuring almost identical interior furnishings with a work table and reading light replacing one of the chairs.<ref name = "An-2"/>
* '''An-2PD-6''' (Polish: ''Pasażerski [samolot] Dyspozycyjny'' – executive aircraft's) – A prototype six seat VIP variant of the An-2P produced at WSK-Mielec in 1970, featuring a folding table, [[mini-bar]], pantry and toilet.<ref name = "An-2"/>
* '''An-2PF''' – Soviet production An-2 aircraft configured for photo-mapping/survey tasks with camera hatches protected by sliding hatches on the undersurface of the fuselage.<ref name = "An-2"/>
* '''An-2PF''' – A joint request from the Polish State mapping Agency (''Państwowe Przedsiębiorstwo Kartografii'') led to Polish production of eight 'An-2PF' aircraft configured for photo-mapping/survey tasks with camera hatches protected by sliding hatches on the undersurface of the fuselage.<ref name = "An-2"/>
* '''An-2PK''' – A polar research aircraft developed by WSK-Mielec with heated skis, insulated cabin and an additional cabin heater.<ref name = "An-2"/>
* '''An-2PRTV''' – A single Polish production An-2, (SP-TVN, c/n1G 15944), modified as a television broadcast relay aircraft for the Polish Radio and Television Co. (''Polskie Radio i Telewizja'').<ref name = "An-2"/>
* '''An-2R''' (Polish: ''Rolniczy'' – agricultural) – WSK-Mielec manufactured agricultural variant with tank for {{cvt|1300|kg|lb}} of liquid or powdered chemicals.<ref name = "An-2"/>
* '''An-2RA''' – A projected up-graded Agricultural aircraft, based on the An-2R, developed at WSK-Mielec.<ref name = "An-2"/>
* '''An-2RT''' (Russian: ''Rele Translyator'' – relay translator) – A single An-2 was converted to a telemetry relay station, for missile development work, relaying telemetry from test missiles to a ground station.<ref name = "An-2"/>
* '''An-2S''' (''Sanitarnyy'' – medical) – The An-2S was an adaptation of the standard An-2T cargo plane with up to six stretcher patients or three stretchers and six walking wounded along with attendants and support equipment.<ref name = "An-2"/>
* '''An-2SKh''' (''Sel'skoKhozyaistvennyy'' – agricultural) – The agricultural version optimised for crop-spraying and crop-dusting. A metal construction chemical hopper was installed in the cabin near the centre of gravity, feeding a spreader through a 300mm orifice. The original spreader was replaced in 1975 by a standardised RTSh-1 three channel spreader which increased distribution width from {{cvt|18|-|22|m}} to {{cvt|34|-|36|m}}. Liquid chemicals could be sprayed using an interchangeable system which delivered chemical to spraybars via a ram air turbine driven regulator pump to give coverage {{cvt|30|m}} wide. Powdered or granulated chemicals were loaded through a hatch in the roof of the cabin and liquid chemical through a special connector on the port side of the fuselage. Early An-2SKh's were typically limited to a 6,000-hour life, as opposed to a normal life of 12,000 hours, due to the corrosive effects of the chemicals. The introduction of epoxy based corrosion protection systems partly alleviated the situation, allowing the agricultural An-2s to continue flying for much longer. Five An-2SKh aircraft were converted to firefighters, from 1954, by pressurising the hopper filled with water and/or retardant and ejecting it from a nozzle in place of the dusting/spraying equipment, single aircraft were allocated to Civil Air Directorates across the country but proved relatively ineffectual.<ref name = "An-2"/>
* '''An-2T''' (''Transportnyy'' – cargo) – The baseline first production model for cargo and mail carriage.<ref name = "An-2"/>
* '''An-2TD''' (''Transportno-Desantnyy'' – cargo/paratrooper) – paratrooper version with 12 seats, static line attachment cables and drop signalling lights.<ref name = "An-2"/>
* '''An-2TP''' (''Transportno-Passazhirskiy'' – cargo/passenger) – A convertible passenger/cargo version, with [[tip-up seat]]s for ten, released in 1949.<ref name = "An-2"/>
* '''An-2TPS''' (''Transportno-Passazhirskiy Sanitarnyy'' – cargo/passenger medical) – Polish production of ambulance aircraft derived from An-2TP aircraft with three stretchers each side and two medical attendants.<ref name = "An-2"/>
* '''An-2V''' (''Vodnyy'' – water-based) – A seaplane version of the baseline An-2 fitted with twin floats supported on wire-braced struts at the undercarriage attachment points and rear fuselage. Floatplane An-2s manufactured in Kiev were designated An-4 but there is little evidence that this designation was widely used. At least one An-2V.<ref name = "An-2"/> [https://www.youtube.com/watch?v=kyhapPe2Fic AN-2V Video]
* '''An-2V''' (''Vysotnyy'' – high altitude) – Six aircraft were built, at the Kiev factory, as weather reconnaissance An-2V's for use at high altitude. Powered by the ASh-62IR/TK turbo-charged engine, they differed from the 'An-6 Meteo' by not having the observers cockpit forward of the fin.<ref name = "An-2"/>
* '''An-2VA''' – water bomber.<ref name = "An-2"/>
* '''An-2W''' (''Wodnosamolot'' – seaplane) – Polish production of the An-2V, also sometimes designated An-2M (not to be confused with the improved variant).<ref name = "An-2"/>
* '''An-2ZA''' (''Zondirovaniye Atmosfery'' – atmosphere sampling) – The initial designation for a high altitude meteorological research re-designated as the 'An-6 Meteo'.
* '''An-3''' (first use of the designation) – A radical redesign of the An-2A to intercept reconnaissance balloons from US intelligence assets, over-flying the USSR. With a high aspect ratio monoplane high-set wing, turbo-charged ASh-62IR/TK and a combined searchlight/gun turret mounted on top of the rear fuselage.<ref name = "An-2"/>
