stress analysis of aircraft transparencies
anyone know of a reference book or paper on design and stress analysis of aircraft transparencies (canopies)?
do you have the book aircraft structures by david j. peery and j. j. azar?
look in the section for shear flow (5.5 of 2nd ed.). it is not directly canopy, but gives theory to determine stresses that would appear in the canopy.
published by mcgraw-hill 1982.

thanks,
i don't have that book, but someone at work might.
hi,
a canopy is basically a thin shell subject to distributed loads (internal pressure and external aerodynamic pressure.
it should therefore be analyzed as a shell. the best tool for this is finite element analysis.
a good article on this subject is "finite element modelling of a fighter aircraft canopy acrylic panel" by john l. labra in the journal of aircraft, vol 19, number 6 (1982).

check out the following references:
mil-hdbk-17 part-ii "plastics for aerospace vehicles, part ii transparant glazing materials.
mil-w-81752 "windshield systems, fixed wing aircraft..."
mil-c-81590 "canopy systems..."
