The milestone keeps the AR1 on track for certification for flight in 2019 as a replacement for the Russian RD-180 engine that is used today to launch most
"This important milestone keeps AR1 squarely on track for flight readiness in 2019," said
The CDR not only focused on the AR1's detailed design to ensure that it meets the rigorous performance requirements of a booster engine prior to full-scale manufacturing, it also validated the production processes that will be used to produce the flight engines. The comprehensive review was attended by government and industry experts who are independent of the program. These experts viewed and assessed the program's readiness and confirmed the technical effort is on track.
"Completing the CDR is a significant milestone for the AR1 program. It means that we have finalized our design and confirmed that it meets the diverse set of operational requirements necessary for national security missions," added Drake. "Leading up to CDR, we manufactured major components at subscale and full-scale dimensions and completed hundreds of tests to confirm that we are ready to build our first engine for qualification and certification."
The system-level CDR is the culmination of 22 incremental CDRs and critical subsystem testing, such as full-scale performance testing of the preburner and staged combustion system. Additionally, more than 200 engine system-level design requirements have now been established and verifications are in place.
"Using our proven development methodology that has been honed during decades of designing booster engines such as the RS-68 and RS-25,
