Where to find information?

[Bidule]

Good morning,

I am (only) an airplane guy. However, as I have time available at this moment (:)), I would want to use it to better know the helicopter world.
Would you recommend any website, book where i can find general information on the helicopters world (various types of aircraft, aerodynamics, propulsion, utilisation of the helicopters, various optional equipment for different missions - winch....)?
Thanks for your reply.

Try this for technical but easy reading
https://www.amazon.co.uk/Principles-Helicopter-Flight-W-J-Wagtendonk/dp/1560276495/ref=sr_1_17?crid=IR8DEGI8GXNX&dchild=1&keywords=helicopter+aerodynamics&qid=1588663018&sprefix=Helicopter+ae%2Caps%2C149&sr=8-17
And this is widely regarded by RW people as the finest book written on helicopter operations
https://www.amazon.co.uk/Chickenhawk-Robert-Mason/dp/0552124192/ref=sr_1_1?crid=3TTFW09Q7KWH0&dchild=1&keywords=chickenhawk&qid=1588663204&sprefix=Chickenhawk%2Caps%2C155&sr=8-1
