double helix shaped turbine

my idea, which i have no clue if its effective or even feasible, is to shape compressor blades like a double helix or similar form. my original idea was inspired by an old school push-type "reel" lawn mower, the kind with the barrel shaped set of spinning blades.

in my compressor idea the the blades would similar to the shape of the lawn mower blades --air would be compressed by the vanes against the engine housing (traditional cigar or tube shape)-- and the blade itself would get smaller from one end to the other. fuel could be supplied by ports farther down the housing that get exposed as the vanes spin.

in theory the turbine i describe would be hollow in its core, but i suppose you could use multiple sets of concentric vanes to fill in, maybe spining the other direction.

not sure if this would work or how it would affect effeciency, complexity, etc. or even where it could be used effectively (i like the idea of using a small turbines to power electric motors for cars though)

EDIT: i added the pic "more like this" to give a general idea
