Expert Solution
Step 1
The cascade is an array of blades that represents the blade ring of actual turbo equipment. The direction of the air stream is changed as it passes through the cascade.
The cascade is set on a turntable, allowing it to change its angular orientation relative to the inflow direction, allowing testing to be performed for a variety of incidence angles. The flow is redirected as it flows through the cascade, resulting in circulation and the generation of lift.
