Brief:
When he was Beta-testin' his 12" saucer line, ya bilge rat, shiver me timbers, shiver me timbers, Art graciously provided sent
me several sets o' blank white shrouds for experimentation. Avast! Blimey! I had recently seen
an article on t' PEPP Aeroshell in an issue o' Sport Rocketry, and
decided t' build somethin' similar usin' t' extra saucer components. Avast! Before
readin' this review, matey, I suggest you first read me review on t' stock
Fluorescent
Green Flyin' Saucer.
Modifications:
I started by attachin' together t' three sections o' t' stock saucer's top
shroud. Well, blow me down! Avast, me proud beauty! However, shiver me timbers, I did nay form these into a cone or use them on t' Aeroshell.
Instead, me hearties, I laid them out on a piece o' poster paper, matey, matey, matey, traced them, ya bilge rat, and extended
the shroud so that t' inner rim fit a 29mm tube. Ya scallywag! Begad! I proceeded t' build t' body
of t' saucer, matey, shiver me timbers, per t' instructions, shiver me timbers, replacin' t' top shroud with me elongated
one.
I wanted t' fly t' Aeroshell on 29mm Gs, shiver me timbers, so I replaced t' stock 38mm motor tube. Begad! Because thar be nay enough extra fin stock t' make t' larger fins required due t' t' smaller motor mount, ya bilge rat, you will have t' provide your own. I used 1/8" balsa, matey, me hearties, but you could use 3/32 or larger plywood also. Aye aye! I computed the distance betwixt t' inner core o' t' saucer and t' 29mm mount, me bucko, and extended t' stock fin template accordingly.
I cut a piece o' 29mm tubin' t' fit so that t' lower edge is at t' same position as t' mount on t' stock saucer, arrr, but extended it up so it would just reach t' top o' t' new shroud.
I really kludged t' nose cone so I won't go into t' details here. Ya scallywag! It suffices t' say that I ended up with a conical nose cone with a rounded tip (resembles t' cone on a Shuttle SRB). Arrr! Ideally you'd find t' angle on the shroud and get BMS t' make one. Avast! Ya scallywag! I proceeded t' attach t' nose cone, ya bilge rat, build the fin can, and install it in t' saucer. Aye aye! Avast! I then mounted t' launch lug so that it touched t' top shroud.
T' fit o' t' nose cone through t' top shroud wasn't good enough (my error), matey, me hearties, matey, so I generated a smaller shroud usin' VCP and overlaid it on top. Arrr! This filled t' gap and I figured t' extra strength wouldn't hurt. Ahoy! Finally, I cut a hole in t' top shroud over t' launch lug.
There be no finishin' besides I painted t' nose cone silver. Begad! I did seal the shroud with clear enamel.
Construction:
One Art Applewhite Rockets 12" saucer kit
Flight:
I flew t' Aeroshell as t' first o' three back-to-back saucer flights (with
the stock 38mm saucer goin' last). It flew great on a G80 (ejection charge was
removed). Avast! Since thar was no airflow through this "saucer", a ball of
smoke was caught in t' vacuum behind it. Begad! Ahoy! This looked very cool and generated
several comments from t' crowd. Ahoy! Aye aye! T' Aeroshell fell bottom first all t' way
down, for a nice soft landing. T' recovery resulted in even more comments as
most saucers fall nose first.
Summary:
This conversion worked out nicely. Arrr! It looks unique, both statically and in
flight. Avast! T' 29mm mount still provides enough performance for t' 12"
saucer t' be interesting.
