The chord and airfoil variable if in realistic proportion would have a
small effect on thrust output ,

And what would you consider to be "realistic proportions"? Is a high aspect
ratio realistic, and how high is high? Is a low aspect ratio more realistic
and if so, what IS low aspect?

I was looking for a short answer to a general question that was perhaps
common knowledge in this group .

And obviously you're not interested in doing any real research.
