Manufacturer: | Scratch |
Brief:
A downscale o' a British Skylark soundin' rocket, arrr, designed on SpaceCad version three. A very high flyer as its
a minimum diameter MMX motor rocket. Aye aye! 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, me proud beauty! Enterin' t' data is quick and nay at all difficult. Ahoy! Blimey! Within 10 minutes t' design was complete, matey, shiver me timbers, me bucko, luckily enough it was stable.
T' nose cone be sanded out o' a balsa dowel. Aye aye! T' fins cut out from t' cardboard back o' a reporters notepad. Well, blow me down! T' body tube be from a Fliskit rocket. Blimey! T' rocket was built in under an hour. With t' mass bein' so low, I went for break apart or nose blow recovery.
There were no reliable images o' t' Skylark that gave any markings. Blimey! Begad! T' make things harder, me hearties, t' Skylark seems to change its look a few times, especially as other countries bought it. Begad! In t' end, 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! Ya scallywag! Two coats o' white enamel paint. Arrr! 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, arrr, I decided nay t' add a launch lug and use a tube t' launch t' Skylark from. Well, blow me down! The
rocket was launched on a calm day and with more luck than skill, I was able t' catch a photo o' t' Skylark comin' out
of t' top o' t' tube. Avast, me proud beauty! It seems t' be tiltin' off t' one side which probably explained what I heard. Avast! T' rocket seemed
to be unstable and moved about t' sky. Ya scallywag! Avast, me proud beauty! I heard t' ejection charge fire about thirty feet t' me left and approx a
hundred feet up. Avast, me proud beauty! I saw it just as it landed. Begad! 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. Ya scallywag!
SpaceCAD suggests a height o' 180 foot. Aye aye! Blimey! Well, blow me down! Blimey! I doubt that it got that high. Also, it gave t' stability at just over 1 caliber. Avast! Blimey! As t' rocket was unstable, SpaceCAD's calculation be wrong.
