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