I did not arrange this order, this is the order of adjectives from grammar textbooks.
E.g. "Little red riding hood"
[Attitude, color, purpose + noun]
Yes, you can write it the way you did.
But when you describe with adjectives a certain noun, and there is a line of adjectives before a noun and nothing else, then there is a definite order in English, is not there?
"Rotor" in my case is a big metal thing that is basically a cylinder in shape with a number of journals.
If the "rotor" is used in my context ("rotor model"), couldn't it be an ajective? (The term "scaled rotor model" is ok with our US customers.)
I thought it was a model to test the rotor, that is why I identified it as denoting the "purpose".
