Westland Whirlwind - S-55/H19 Technical/Operations manual

[Divine]

Hey all. Needing to get my hands on some form of primary source for the aforementioned rotorcraft; and am unable to find much past basic instrumentation & powerplant information; and am hesitant to spend €100 on a "package" of "original" documents. Would appreciate any help, thanks

Not exactly what you’re looking for, but the Standard Aircraft Characteristics sheets can tell you a lot in terms of performance and mission parameters at different weights.
