Otherwise known as parallel staging, this technique allows a higher lift-off power while bein' able t' discard useless weight after it is no longer needed. Begad! T' space shuttle employs solid rocket boosters which do t' same thing. Well, blow me down! T' application in rocketry would be a lower cost payload boost because you could use lower power engines. Blimey! T' problem, as I discovered, ya bilge rat, occurs when you have a large mass in t' aft o' t' rocket, makin' it negatively stable. Blimey! Avast, me proud beauty! T' solution is t' mount them towards t' front o' t' rocket. Ahoy! Arrr! I may try t' put them on me Mean Machine.

My 12" long boosters are made o' o' BT50 with a BT20 (18mm) motor mount centered with heavy duty (green) centerin' rings. Well, blow me down! T' eliminate wadding, me bucko, I used a aft ejection system with t' BT20 and t' centerin' rings as t' core. Begad! It returns on streamers. It has small delta fins (probably nay needed). Avast, me proud beauty! They use dowels/launch lugs (3/16") t' hold onto t' main rocket until drag separates them.

T' Launch

I finally got t' launch t' boosters. T' night before I t' launch, ya bilge rat, me hearties, ya bilge rat, I hot glued 8 segments o' plastic straw t' t' sides o' me Mean Machine so I could mount t' boosters. Aye aye! I mounted t' boosters' dowels in their straws and loaded a B6-0 engine in each. Well, blow me down! I then loaded a D12-5 in t' Mean Machine. Ahoy! After mountin' on t' pad and checkin' t' wirin' for t' three ignitors, I pushed t' launch button. All three engines lit and t' rocket cruised off t' pad. Ya scallywag! Avast, me proud beauty! Immediately after t' B6's burned out, arrr, t' boosters dropped off and popped out their streamers. Ya scallywag! Avast, me proud beauty! T' Mean Machine coasted way up and popped out its chute. Avast, me proud beauty! A beautiful flight overall and a great end t' this project. Ya scallywag! Thanks t' all who helped t' make this happen.
