Critical Design Review (CDR)

To complete the Critical Design Review Aerojet Rocketdyne had to validate its production processes, including the use of 3D printing. With the technology often cited as difficult to certify in comparison to conventional manufacturing techniques, if not purely for the fact it is more contemporary, passing this milestone was a significant feat.

In order to pass the review, Aerojet Rocketdyne may have benefited from its recently announced partnership with Sigma Labs. Sigma Labs is the creator of PrintRite software which can certify additive manufactured parts thereby making validation easier. By passing this latest CDR, the engine design team has now completed 22 component reviews leading up to the final engine qualification aimed for 2019.

CEO Eileen Drake explains that this milestone means the engine design is now finalized and confirmed before stating the company is “ready to build our first engine for qualification and certification.”
