Blackhawk Intake Cowl De Ice System
That makes sense to me. I have the IPC and it is difficult to see what is under a cutaway in the cowl: I don't have enough detail. However, it appears that there is an RGB driving the rotor at the front of the engine, sitting on a shaf, and there wouldn't seem to be enough room for sufficient ducting off of the compressor to heat that cowl.
If you can a diagram of the piece, that would be appreciated: I'm waiting for one from Redstone Arsenal now ... but they can be quite slow.
I am making a different system, under an STC, for the S61 Sea King .. similar to systems I make for planes such as the Convair, Electra, C-130/L100, Fokker, Saab, and others. I'm looking for helicopter applications that utilize a heated mat system such as what you have described: That wire based system is substantially inferior to the system that we make, which utilizes a flame spray of metal that is wider and therefore more resistant to FOD.
