Brief:
I really like my
Art
Applewhite 6" Delta saucer. Aye aye! However, me bucko, since it appears that it will
last for many, many more flights, I didn't think I needed a second one just
yet. Arrr! So what t' do with me Spaceship Earth Delta?
Modifications:
I began by
constructing
the Delta: Cut and form t' top and bottom shrouds and t' center foamboard
plate, ya bilge rat, bevel t' edge o' t' plate, and glue t' top shroud t' t' plate. Ahoy! Then
in place o' t' provided motor tube, I merely used an 12" Apogee 24mm
tube. Begad! Finally, me hearties, shiver me timbers, ya bilge rat, I added t' bottom shroud, ya bilge rat, makin' sure t' launch rod guides on
all components were aligned.
Construction:
T' build requires:
T' rest was trivial: hook eye in t' cone and attach t' shock cord t' the body. For t' latter, ya bilge rat, I used a small piece o' a 24mm motor casing. Blimey! Avast, ya bilge rat, me proud beauty! I notched the outside so that when t' Keelhaul®©™® was tied around, ya bilge rat, me bucko, it would lie flat with t' outer rim. Arrr! Avast! This was mounted several inches down into t' body tube.
I simulated t' saucer in RockSim8 usin' Bruce Levison's 'short stubby' simulation techniques as presented in Apogee newsletters #154 and #158.
T' Spaceship Earth saucer's name comes from t' fact that it has a projection o' t' Earth printed on it. Avast, matey, me proud beauty! Blimey! T' 24mm cone I had layin' around resembled a capsule (any cone would work). Blimey! Blimey! NASA's Crew Exploration Vehicle is in t' news. Begad! Blimey! Hmmm, arrr, guess I'll call it t' Crew Exploration Saucer.
Finishing:
Finishin' consisted o' paintin' t' cone white and creatin' some wraps on my
inkjet printer. Well, blow me down! T' lower wrap has nozzles, flames, arrr, and smoke. Begad! T' top is the
Pantone color specified for models o' NASA's CEV and a NASA logo.
Flight:
Simulations said it would be stable under any conditions. I loaded dog barf
waddin' and a 12" Estes chute, me hearties, ya bilge rat, friction-fitted a D12-3, ya bilge rat, and tested out the
theory.
Recovery:
It flew just fine although t' ejection, ya bilge rat, even with t' short delay motor, ya bilge rat, me hearties, was a
bit late. Well, blow me down! Nevertheless, t' chute opened and it recovered well.
Summary:
This was just another use for Art's simple yet robust kits. Ahoy! If you have an
extra, ya bilge rat, me hearties, you might try makin' a variation on this theme. Avast! This rocket needs long
burn, short delay motors!
