Sorry to disagree, the layout of the flight IS a drawing problem requiring triangulation. By doing this you find the true size of the inside and outside "diameters", and as you say a little twist and a weld.
Working with grain elevators and harvester equipment (imported) one collects a number...

Maybe you'd like to start with a model V8 plans and castings available on my site.
We have managed to get 3.2HP at 5000RPM.
Specification 1/2" bore, 3/4" stroke approx 1/6 scale. Length 5 5/8", width 6 5/8", height 7/78" over air cleaner, 6 1/8" under bonnet...
aerobab,
Perhaps, in answering MRM's question, you would like to explain, briefly, in simple terms, what changes occur to the airflow over an aircraft as it approaches the speed of sound.
Was I wrong in saying that "The atmosphere follows those principles when a body is travelling through...
Bernoulli's principle is valid for all fluids. The atmosphere follows those principles when a body is travelling through it until the airflow reaches the speed of sound.
Air acts as a fluid and therefore is incompressable at speeds below the speed of sound but when a body travels at speeds...
The most acceptable formula for calculating bend allowance, and used throughout Aussi aviation industry is
BA= 2 pi x (inside radius + half thickness) x angle of bend in degrees / 360, as a formula 2 x 22/7 x (R + T/2) x A/360 if you are working on outside radius formula becomes 2 x 22/7 x (R -...
