hello does anyone knows how the old planes like the connies and the dc6 dc7 were presurized i mean using bleed air form the engines or if they had a separate compresor. I know the modern planes uses bleed air from the engines but the new planes are made out of plastic I do like the old heavy ones those were really planes.

The prop liners bled air off the turbochargers used to boost engine performance.

Some of the aircraft had shaft driven compressors to pressurize the cabin. When jets came in they removed the shaft and attached a turbo and called it a turbo-compressor and used freon cooling for airconditioning (just like your car). Turbo-compressors were on such aircraft as 707 and DC-8.
