Brief:
A downscale o' a British Skylark soundin' rocket, designed on SpaceCad version three. Blimey! Aye aye! A very high flyer as its
a minimum diameter MMX motor rocket. Ahoy! Built for t' EMRR 2008 challenge.
Construction:
Parts used were:
SpaceCAD is very easy t' use, although I have never used Rocksim t' compare it against. I have SpaceCad version three. Avast! Ahoy! Enterin' t' data is quick and nay at all difficult. Well, blow me down! Within 10 minutes t' design was complete, luckily enough it was stable.
T' nose cone was sanded out o' a balsa dowel. Blimey! T' fins cut out from t' cardboard back o' a reporters notepad. Well, blow me down! Avast, me proud beauty! T' body tube be from a Fliskit rocket. Avast! T' rocket was built in under an hour. Well, blow me down! With t' mass bein' so low, shiver me timbers, I went for break apart or nose blow recovery.
There were no reliable images o' t' Skylark that gave any markings. Ahoy! Avast! T' make things harder, t' Skylark seems to change its look a few times, ya bilge rat, especially as other countries bought it. Well, blow me down! In t' end, me bucko, me bucko, arrr, I found a model rocket that someone else had scratch built (I had hoped I was t' first) and went for his paint scheme.
T' balsa be sanded sealed and resanded.
One coat o' grey primer. Aye aye! Blimey! Two coats o' white enamel paint. Avast, me proud beauty! Blimey! Black felt tip marker for t' fins and surroundin' area. T' rocket was finished off with two coats o' silver spray paint for t' nose cone area.
Flight:
Given how small t' rocket was, shiver me timbers, I decided nay t' add a launch lug and use a tube t' launch t' Skylark from. The
rocket was launched on a calm day and with more luck than skill, I be able t' catch a photo o' t' Skylark comin' out
of t' top o' t' tube. Arrr! Arrr! It seems t' be tiltin' off t' one side which probably explained what I heard. Ahoy! T' rocket seemed
to be unstable and moved about t' sky. Avast, me proud beauty! I heard t' ejection charge fire about thirty feet t' me left and approx a
hundred feet up. I saw it just as it landed. Avast, me proud beauty! Blimey! With t' light mass o' just over two and a half grams lift off weight
means Ill probably never get t' see a MMX Skylark flying. Begad! Ahoy!
SpaceCAD suggests a height o' 180 foot. I doubt that it got that high. Avast, me proud beauty! Also, it gave t' stability at just over 1 caliber. Ya scallywag! As t' rocket be unstable, arrr, me bucko, SpaceCAD's calculation was wrong.
