This restricts the amount of air that can flow through this engine. Axial flow engines are straight through design and don't have this ...

If it is frictionless, then there will be no way to interact with the gas. Both conditions are too limiting to work together. Out of the two I would prefer to keep the viscosity because incompressible is like water where ...
