Gents, for who is interested, the Simla, big son of the Oldest Taurus on Earth.

To redesign I often use solver calculations I can program in my Hewlett Packard calculator.

When I have too much input variables to calculate or, if I want to archive the calculations, I make these calculations in Excel.

A typical example to use solver calculations is to redesign the Simla, all data packed in a lot of valuable pictures and plans.
Only when use all the important data in one calculation model it is possible to recalculate the dimensions with accuracy.
Making the program that can do the job is the first challenge and a separate project,
Making a “model” that can do all the different calculations for that is a kind of reversed computed added design. (RCAD?)

It’s all classic pattern flying, so my hobby, and for that I did start.

First results: dimension sketches and some detailed construction plans.
Because making the top of the fuselage is time consuming I already start with making the plug, see picture 1.
To see results, picture 2, the Oldest Taurus on Earth, study picture with a “photo shopped” side mounted engine, enlarged canopy and Simla painting scheme on the fuse. Just a picture.

Don’t forget, the Simla isn’t on the top of the list, first priority, only to have a (nose wheel?) brake some times and to learn.
And when will the Simla project will be finished?
Only when I see the compare pictures and I am content just as with the crate picture and the Oldest Taurus on Earth because telling all this interesting stuff is no prove!!
Or is it?
