Why are bombs, the ones dropped from airplanes, shaped like an oval with fins on one end? Why aren’t they spheres so they just fall down onto the target?
In: 7
They are shaped to reduce drag during flight. Spheres are not very aerodynamic.
Then bombs are standard, rarely you see different designs for exterior and interior carried bombs. Most cases they make an exterior carried bomb and then used it for interior carrying too.
Then when you drop them you want the bomb to spin to retain accuracy, so you need a fin with a twist. Again sphere with fin is not practical. The more elongated the bomb is the less it aerodynamically mask the fin. Too elongated it becomes unstable during the spinning. So you see that 2 to 10 ratio in length to width. The most elongated, the 10, are made with fast jets carrying them outside in mind.
