how to design small diameter high static thrust rotor?
Fixed wing aircrafts use i some cases winglets on the wingtips to prevent air escaping from the high pressure side underneath the wing to the low pressure side over the wing. This makes the wing more efficient. With a propeller, or a rotor, with winglets, wouldn't that act as a ducted fan with...- permagne

I doubt that it's possible to make an UL plane human powered. Im flying an zephyr 2000 UL which has a glide ratio to...- permagne

Blast analysis on A335 P11, yield stress
Hello I'm doing an analysis on a system using A335 P11 pipe at 400'C (app. 750'F) and 33barg. Whan doing blast analysis I exceed the pipes allowable stress, but as criteria for blast analysis the material can be utilized for 0,9*yield stress of the material. In tabel A-1 (B31.3) allowable...- permagne
