This page shows the different variations of the Ster strumieniowy from an Icons8 icon pack. Feel free to resize and recolor the icon, and then download the icon in PNG format for free. Icons are available in PNG and vector.
The icon is a simplified depiction of a rocket thruster, used to provide propulsion in vacuum, microgravity environments. The nozzle points to the south-west of the image, connected by a narrow fuel pipe to the body of the thruster, an egg-shape ending in a point to the north-west.
