Development and types of aircrafts used after the second world war?

Question

i want to no wat kind of aircrafts came in
on commercial level

Answer 1

well there was a glut of military transports that were converted to civil use. The constellation and DC-4 and 6 and of course the DC-3. Some bombers were converted to civil use like the Lancaster which was used as an airliner. There were new planes like the Baragon an interesting plane with eight engines powering four counter rotating props. Then came the comet the 1st jet liner that sank the baragon. Small plane ownership exploded after the war due to excellent designs like the piper cub. The B-29 went through several massive redesigns that produced the stratoliner and the massive cargo plane the guppy. In the area of flying boats Britain produced the huge princess class of liners also with counter rotating props but the glut of land based airports spelled the doom of flying boats.Helos started to be really useful especially the bell -47 which you see in shows like MASH. This would be the 1st truly successful civilian helo. In Russia they produced the IL-12 to 14 these being basically DC-3 with tricycle landing gear and were very successful in the Warsaw pact nations for years. I am not including jets as they didn't really hit the civilian market until 1957. I am not sure you want to go that far.

Answer 2

There are a lot of WW2 bombers and transports that were used after the war in civil transports.
Dc-4, Constellation
Also in Italy a lot of military planes of the war were used or had a civil version.
For example Fiat G.12, Siai-Marchetti S79, Sm-82, were used in civil transport also in other countries(S79 in Lebanon), also the strategic bomber Piaggio P108 had in 1942 his civil version with a pressurized fuselage for 32 passengers.
I'm Italian, so I told you about Italian planes because I'm sure that someone will tell you about American or British planes but none will do about planes from other countries.
