I am reminded of the NASA propultion enginners that refused to believe a specification for a rocket motor developed in the 60's in the USSR. When they observed it during tests exceeding the spec they realized they were 40 years behind... Many military /research rockets now use this motor under licence in the USA...
Yeah, engineers get stubborn. Good thing I'm not an engineer!
BTW. Do you have any link or articles that deal with these new impellers and diffusers? I'd like to read about them.
