Is there any way to calculate the thrust provided by a propeller, given only the geometry of the propeller and the windspeed.
Given:
Stationary propeller
Wind Speed = 30 m/s
Blades = 10
Propeller Geometry:
Constant Chord length (γ)
Square tip Propeller
Pitch at root = α
Pitch at tip = β
Advance ratio = 1.17
Propeller Rotation = ω
Blade Span = ε
Blade Diameter = μ
Hub Diameter = σ
Assume linear change in pitch
We do not know the downstream velocity therefore thrust calculation is complicated. Any ideas how to go about this problem? I am also starting to learn CFD calculations using Fluent but the mesh is very complicated. I must also check using some numerical solution. Ideas?
Thank you
