This is a picture of a jet engine and you can see the fan going around. it has a circular center with spokes all around it. the rim of the engine can also be seen.
This is a Jet Engine icon. We've made it in iOS style
, first introduced in iOS version 7 and supported in all later releases up until now (at least iOS 11). This style is based on thin two-pixel lines and is optimized for 50x50 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 13,300 icons, all in the same style and quality.
