9 commentsIncredibly impressive if true. But below quote makes it sounds like they purchased a company with mostly ready design and made a prototype. Still pretty awesome.
> The successful development and testing of the dual-mode ramjet in such a short period of time was made possible through the collaboration of GE Aerospace’s team of engineers, Innoveering – a company acquired by GE Aerospace in 2022 that specializes in hypersonic propulsion – and GE Aerospace’s Research Center.
Now I want real engineering / everyday astronaut like breakdown of how it works.

They really seem to love to talk about how fast they move except wait:

Per the above in 2019 they had been developing RDE technology for 5 years.
Now developing the tech is different then building a prototype but it's good to take these timetable numbers with a large dose of salt.
It is interesting to see RDE's getting alot of headlines recently. Really cool tech that works off of a principle known for a long time but only just recently hitting an inflection point in terms of development.
Cool video from Scott Manly talking about RDE's: https://www.youtube.com/watch?v=rG_Eh0J_4_s
The waverider program was a huge success, then suddenly funding stops and nothing is heard about it anymore. That was over 10 years ago, and now we have a commercially-developed dual cycle engine in under a year.
It’s my personal opinion that the technology was developed further internally for weapons and surveillance platforms like the SR-71 was back in the day. The technology just has too much potential.
Supersonic has been DoA for a while because post-deregulation airlines are only interested in ever more fuel efficient aircraft. (It’s also why major states like Japan, China and Russia have for the most part failed to build a competitive airliner against the duopoly.)
It's a waste of money though as the Ukraine war showed that the Russian Kinzhal missile have limited utility and can be intercepted.
Naval drones and long-range drones are not only cheaper but also more effective.
