STRUCTURES

lightweight structures

- a more concrete interpretation of "design".

- not my specialty, certainly the static structures are not.

- I won't talk about domes and bridges ( traffic vs. trains ).

- still a few remarks on lightweight design, for the love of airplanes.

tension and compression

- tents.

- concentrate compression (against buckling).

- spread tension (cable endings have volume).

- early aircraft

- torsion - don't let the canary out.

- biplanes and sesquiplanes.

- torsion.

shear and the thin wall

- thin-walled structures

- similar in modern aircraft and in ships.

- shear.

- torsion.

- stressed skin (compression).

- fail safety.

- Gordon - "New Science of Strong Materials" - ship's caulking.

aero engines

- limit myself to aero engines, as machines go.

- radial engines.

- sleeve valve engines.
