SOLID PROPELLANTS [PDF]

open access: greenRubber Chemistry and Technology, 2019
ABSTRACT Solid propellants are energetic materials used to launch and propel rockets and missiles. Although their history dates to the use of black powder more than two millennia ago, greater performance demands and the need for “insensitive munitions” that are resistant to accidental ignition have driven much research and development over the ...

Propeller Flaps

open access: yesIndian Journal of Plastic Surgery, 2022
AbstractA propeller flap is an islanded flap that reaches the recipient site through an axial rotation around its vascular axis. The degree of rotation varies from 90 degrees to 180 degrees. It is a highly reliable local reconstructive option. These flaps are simple, single-stage, easy to harvest, and not constrained by routine length-to-width ratios ...
