SuperDraco

The SuperDraco is a liquid rocket engine developed by the American space company SpaceX with a thrust of 73 kilonewtons. It's an evolution of the Draco engine and about 200 times bigger. Like this, it works with the hypergolic fuel mixture methylhydrazine and dinitrogen tetroxide , which react spontaneously with each other when brought in contact.

SuperDraco in the Dragon V2

Eight SuperDraco engines, each arranged in pairs, are installed all around the bottom of the side wall of SpaceX's manned spacecraft Dragon V2 . On the one hand, they are used as a launch rescue system and thus replace the classic rescue rocket, and on the other hand, the spaceship should be able to land “anywhere in the country with the precision of a helicopter”. Even if this is still possible according to new information, the landing ability will not be implemented because safety certifications would be too time-consuming and no longer fit into the company's current course.

Manufacturing

The SuperDraco rocket engines are completely manufactured using the 3D printing process laser sintering with devices such as EOS 3D . This makes them the first ever engines to be manufactured entirely using this process.

Inconel , a highly heat-resistant nickel -based alloy from Special Metals Corporation , is used as the material for laser sintering .
