Missile fuel printed on 3D printer was tested

U.S. startup researchers Firehawk announced a successful test of solid fuel for 3D-printer missiles, a new type of fuel that is much more stable and easy to transport.

Although today's rocket engines are technological and powerful, most of them use conventional volatile fuels. Developers have presented an alternative, a structured solid fuel grain. Unlike traditional types, it is easy and safe to transport, and it can also control combustion and drive.

For example, an engine on such a fuel can safely be slowed down, stopped and restarted several times; in the case of liquid missile fuels, the process is generally irreversible in the company: after launch, it must be fully developed to avoid explosion.

Developers note that for each specific task they can create unique fuel grain geometry with specified characteristics. Any such changes require minor changes to the software code and upload it to 3D printer.

During the tests that were conducted at Stannis Space Center under NASA supervision, the company demonstrated the operation of fuel and engines specially designed for it, and the results of the tests confirmed that the company was ready to launch into the atmosphere.
