Random Musings from the Warped Minds of Jonathan Goff, Ken Murphy, John Hare, and Kirk Sorensen. Like Father, Like Son (Jonny Bloggin Edition). A Depressing Implication →. November 12, 2007. So what are the implications of this technology for a rocket design? It allows you to make a rocket that gets excellent Isp in vacuum and excellent T/W ratio on the ground (though your Isp is going to be mediocre on the ground, and your T/W ratio with only the core flow isn’t going to be anything to write home ...
