Just for fun, hovering helicopter

Some basic engineering (before I forget how)

In Prime 4.0

Before retiring, in what field of engineering did you work? 
Aerospace?

Most of my career was as a wind tunnel test engineer for Sikorsky.  They wouldn't let me near the "real" helicopters!

One solution in helicopter's field wthout animation is not a solution 😀

One solution in helicopter's field wthout animation is not a solution

As I'm sure you know Prime will not create animations despite your (and mine, and others') continued harassment.  I would also be challenged to determine how to animate a calculation that develops the performance curve of a hovering rotor.

Sorry!  😐

Dear Fred, would you mind to provide a pdf version of the worksheet?

Thanks in advance!

Thank you Fred. Highly appreciated

Aha.
And how Mathcad was involved in your job?
What did you do there in more descriptive terms?
