  •  They've already launched 5 times with 9 engines (2+ / 0-)

    Falcon 1.0 had the 9 engines in a tic-tac-toe arangement.  And yes nozzle interaction is something to worry about.  But it's not intractable and they have it working just fine.

    with the circular arangement the nozzles are actually less tightly packed now, so the effect on this rocket will be less than they've already delt with.

    As for Falcon Heavy, they have computer simulations based off actual experience, and they will do full 3 minute burns on the ground before ever launching.  If there's a problem, they will find it and fix it on the ground.

    But no, it's not that severe.  And we are way past the early Soviet era.  We're not talking slide rules.
