<div dir="ltr">The Soviet rocket had 24 engines on one hull, and tried to regulate everything with extremely clever plumbing and fluid dynamics.<div><br></div><div>Three hulls with 9 engines per gives a lot more flexibility to dampen out the vibrations that made the Soviet design unworkable, and the control electronics on the SpaceX hulls are much more responsive and flexible than anything you could build in the 60s. The precision on the mechanical components is probably dramatically superior too.</div></div><div class="gmail_extra"><br><div class="gmail_quote">On Wed, Jan 3, 2018 at 11:51 AM, Dave Sill <span dir="ltr"><<a href="mailto:sparge@gmail.com" target="_blank">sparge@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><div class="gmail_extra"><div class="gmail_quote"><span class="">On Wed, Jan 3, 2018 at 1:35 PM, Dylan Distasio <span dir="ltr"><<a href="mailto:interzone@gmail.com" target="_blank">interzone@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr">I'm curious, does anyone here know why they took the approach of many smaller engines versus much fewer larger ones?</div></blockquote><div><br></div></span><div>Scalability?</div><span class="HOEnZb"><font color="#888888"><div><br></div><div>-Dave</div></font></span></div></div></div>
