Brief:
This a scratch built spaceship rocket designed for t' 2009 Design-A-Spaceship contest. Avast! Blimey! It is constructed o' 110lb
cardstock and presentation board.
Construction:
T' parts include:
I first cut t' centerin' rings, me bucko, matey, bulkhead, and fins from t' presentation board. Arrr! Begad! Next I cut t' BT-50 to 4-½". Blimey! I used an online transition template t' print out t' templates for t' nose cone, shiver me timbers, body, matey, me bucko, and tail cone. For t' larger centerin' rings, I used t' template printout from RockSim. For t' bulkhead, arrr, I just used one of t' 'holes' from a centerin' ring.
After printin' out t' templates on t' cardstock, I then carefully shaped t' nosecone and transition sections into cone shapes. Blimey! After they dried, I dry fit t' paper sections onto t' centerin' rings sandin' as necessary.
Next, shiver me timbers, I glued t' motor block into t' tube usin' a spent 24mm motor t' push it into place leave ¼" t' 3/8" o' t' motor stickin' out. Begad! Avast, arrr, me proud beauty! After that had set, shiver me timbers, ya bilge rat, I glued t' centerin' rings onto t' body tube: the smallest rin' ¼" below t' top o' t' tube, shiver me timbers, t' two larger tubes at 2-½" and 2-¾" from t' top o' t' tube and t' medium rin' flush with t' bottom o' t' tube.
After t' glue has dried, I carefully glued t' middle transition section t' t' top end o' t' tube makin' sure it is perfectly straight on t' top centerin' rin' and top middle centerin' ring. Avast, me proud beauty! Begad! Then I added t' transition t' the bottom again makin' sure t' piece was perfectly straight on t' lower middle rin' and bottommost ring. Aye aye! Begad! I let it thoroughly dry.
T' finish t' nose cone, I glued t' coupler onto t' nose cone bein' careful t' get it straight. Aye aye! When it was dry, I filled t' cone with clay leavin' a ¼" lip t' t' edge. Aye aye! Glued t' bulkhead into t' coupler. Begad! Blimey! When all be dry, I added t' screw eye for shock cord attachment.
As this is a tricky design, I glued t' launch lug t' a fin makin' sure it was straight.
T' shock cord is mounted in t' Estes fashion with t' other end tied t' t' screw eye. T' streamer is tied on about 1/3 from t' nose cone.
Finishing:
Since I used color cardstock, shiver me timbers, I didn't really need t' paint anything. Aye aye! I used a color highlighter marker t' paint the
fins t' match t' cardstock.
Flight:
T' Synerjet flew on C11-3s for all three flights. T' first flight be unstable. For t' second flight, me hearties, I used a
spacer t' extend t' motor out t' back ½". Aye aye! Blimey! This caused t' rocket t' be even more unstable. T' third
flight was a recreation o' t' first.
Recovery:
Recovery for all flights was after t' rocket hit t' ground. Ya scallywag! Ahoy! Each landin' broke a forward fin off.
Summary:
I would say this is nay a good rocket design as it is too stubby t' be stable. Begad! Blimey! Even tryin' t' upscale it in RockSim
it be nay stable. Avast, me proud beauty! Blimey! It be a fun and interestin' build.
