Musk Heavy vs New Bezos


Suspect because it was a terrorist attack, the cause of the last Falcon 9 explosion won't be disclosed until after the election & H-Rod already had the talk with Musk Rod, for his sake. It'll be quite the stir when he finally reveals it right after H-Rod's election, but maybe Americans will just think it was politically correct for ISIS to blow it up. More of a stir would be if Emirates, Quatar, & Etihad airlines immediately got into the space tourism business, just like how the Islamic airlines took over the industry after 9/11.


In other news, I was intrigued by the fact that the fictional New Bezos would be larger than the fictional Musk Heavy, yet would make 1.5 million lbs less thrust. Musk's strategy was always to clear the tower as fast as possible. Every second of the liftoff burns enough fuel for 9 seconds of the landing. So he puts out 2 million more lbs of thrust than the weight of the rocket.

The liftoff mass of New Bezos was never given, but it would be comparable to Musk Heavy. A lot more propellant would be burned to clear the tower, so all that size would probably end up giving the same payload capacity as Musk Heavy.

7 Bezos-4 engines would make 3,850,000 lbs of thrust. The Musk Heavy would make 5,200,000 lbs of thrust to hurl 3,200,000 lbs.

New Bezos would offer a much bigger payload fairing. The payload volume on a 3 cored rocket is the same as 1 core, limiting the benefit to manely higher orbits of the same payloads or reusability. That's why they emphasize Mars missions instead of bigger satellites. The Falcon 9 core is narrower than the Delta IV.

Anyways, despite Jeff's powerpoint slides, Musk was a lot closer to reality with the manufacturing of a complete Raptor engine before the explosion. It was a lot of money with only 1 purpose: the Mars colonization rocket. It was the most anyone ever committed solely for a lofty goal. He seems to have mastered Autodesk Inventor more than anyone else, taking much bigger leaps based on simulation rather than building unit tests.

Autodesk Inventor seems to be the industry standard. Where improvements in the movie business could be traced directly to the evolution of Maya, every leap in the space program could be traced to the evolution of Autodesk Inventor. Gone are the days of buying a bunch of servos & building something to test a robot. It's all done in simulation.
