   Launch Lugs: What a Drag


dding launch rod or rail "lugs" to your high performance rocket can increase the drag coefficient by as much as 30%!

When designing a high performance rocket, we take great care in converting every newton second of that motor into altitude by giving our rockets an ogive nose, perfectly shaped fins and even that extra meticulous finishing and paint application...only to add launch lugs right out there in the air stream! Following closely behind the frontal area of our rockets in the drag stack-up are launch lugs. Especially in a mach-busting vehicle system, any unnecessary protrusions can produce a significant amount of parasitic drag, possibly as much as 30% of a vehicles total drag coefficient. A tower launch pad can eliminate the need for these external nuisances. Tower type launch pads eliminate the need for launch lugs.
