READ TOP TO BOTTOM IN EACH COLUMN
T' initial concept, rendered in Rocksim.. T' rocksim export, next t' a picture o' t' actual Rocket I tested several battery configurations t' determine t' lightest possible reliable combination. Begad! Well, blow me down! Apparently, 3
AAA cells is sufficient t' light an Estes ignitor if they are fresh. Avast, me proud beauty! I was also testin' t' perfectflight timer that
will be used t' ignite t' sustainer(I hope)
![]() T' humble beginnings o' t' booster, me bucko, pretty simple, a bulkhead placed in t' bottom o' a short piece o' fibre
glass tube, shiver me timbers, with a short piece o' coupler t' attach it t' t' sustainer. Ahoy! 5 minute epoxy holds it all together... Different angle, me bucko, arrr, same part.. Well, blow me down! Blimey! I will likely nuke this page later, shiver me timbers, as it adds no content.. Wow, ya bilge rat, a picture o' t' fin placement template! I bet this one gets deleted too! Well, since it is here, I
measured t' circumference o' t' tube(OD), Divided by 3, and marked a pice o' paper in t' appropriate locations, the
marks were then transfered t' t' sustainer, and t' booster, arrr, t' located t' fins and t' booster motor tubes.. T' almost finished booster...T' motors(24mm) will be retained with maskin' tape, me bucko, matey, and use a maskin' tape thrust rin' as well. T' booster has 3 24mm motor tubes, and should provide enough power t' get it off the pad safely. Avast, me proud beauty! T' nose cones will be attached with 12" nylon cord scavenged from ear plugs. MMM, more angles.. All put together..You can see t' sustainer motor assembley next t' it, arrr, wow huh!

This be t' 24mm sustainer motor mount. As it is aft eject, arrr, ya bilge rat, it is removable. Blimey! Blimey! You may notice t' clips on the
bottom, hopefully they will carry t' current which will light t' sustainer motor. Begad! Ya scallywag! Blimey! At apogee, ya bilge rat, t' engine assembly will
be ejected, pull t' chute out t' bottom, shiver me timbers, and carry it safely back t' earth...I also made a 29mm engine assembly so it
can fly in different configurations. Arrr! Each o' t' engine assemblies also features an eyebolt t' attach it t' t' shock
cord. Well, matey, blow me down! Blimey! They were constructed with wood glue, as opposed t' epoxy. This would be t' battery bay, ya bilge rat, it will fit all t' batteries I want, me bucko, along with t' perfectFlight Timer, with
loads o' room t' spare. This is inserted in t' top o' t' airframe, matey, ya bilge rat, and held in with a piece o' coupler (glued
inside), and secured on t' other side by t' NC, me hearties, which is held on with 2 screws for flight. You may notice, ya bilge rat, thar is
an eyebolt attached, shiver me timbers, as this is where t' shock cord is attached t' t' rocket. There was really no need for t' bulkhead on top, but who knows..I wouldn't want t' batteries t' be able to
leap up into t' NC anyway... This would be t' inside o' t' airframe. Avast! Notice t' couplers, one basically acts as a thrust ring, while the
other keeps t' battery bay in t' airframe. MMMM Fillets...the airframe was roughed up quite a bit prior t' applyin' t' epoxy. T' bottom was removed from t' NC t' provide a little more room. Just after bein' primed, t' rocket took on a little damage, matey, shiver me timbers, a la kidsamine... Begad! All better now... All ready t' go, also in t' picture is a 29mm motor mount, shiver me timbers, so t' sustainer can fly on it's own.. This would be t' 29mm Motor mount all by it's lonesome. Blimey! Begad! All o' t' wood and paper parts were bonded with wood
glue, as opposed t' epoxy. Another VERY excitin' timer test.. I needed somethin' t' light a cluster..so I guess this came with t' project.. Flight Report |
