Re: Antonov An-2
An-2PF
A joint request from the Polish State mapping Agency (Panstwowe Przedsiebiorstwo Kartografi) led to Polish production of eight 'An-2PF' aircraft configured for photo-mapping/survey tasks with camera hatches protected by sliding hatches on the undersurfa ce of the fuselage.[Vous devez être inscrit et connecté pour voir ce lien]

Re: Antonov An-2
An-2SKh (Sel'skoKhozyalstvennyy - 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 18-22m(59–72 ft) to 34-36m(111–118 ft).
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 30m(98 ft) 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 6,000hr life, as opposed to a normal life of 12,000hrs, due to the corrosive effects of the chemicals.
The introduction of epoxy based corrosion protection systems partly alleviated the situation, allowing the agricultural An-2's 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.[Vous devez être inscrit et connecté pour voir ce lien]
