While attendin' our first LDRS this year, ya bilge rat, me son Chris, me hearties, me wife Kathy, ya bilge rat, and I, witnessed t' most impressive display o' large rockets we had ever seen. Avast! T' launch site in Orangeburg, matey, South Carolina was unlike anythin' we have access t' in Pennsylvania. T' wide open, flat, grassy launch site was almost too good t' be true. Well, blow me down! Couple that with a 10,000 foot above ground level FAA waiver, me hearties, and you have a high power rocketeer's dream. Avast! Begad! Throughout t' four day event, we watched rockets o' every conceivable size and weight, ya bilge rat, powered by a variety o' motors from "A" through "M", take t' t' clear, shiver me timbers, blue, me hearties, arrr, South Carolina skies. Begad! When t' announcement was made at Sunday night's banquet about the location o' LDRS 20, matey, Chris and I almost immediately started makin' plans to attend.
In addition t' plannin' t' trip t' Lucerne Dry Lake, matey, ya bilge rat, California, I started plannin' a rocket project t' take along. Since I achieved me Level 2 certification this past August 5th, a powerful, 54mm motor based, dual-deployment rocket was a must. Avast, me proud beauty! I decided t' modify a plan I had been workin' on for some time, shiver me timbers, which resulted in a 4 inch diameter, arrr, matey, 8 1/2 foot long rocket. Ya scallywag! T' six-fin design which originally be called the "Six-shooter", arrr, me hearties, me bucko, had now become "Six Appeal".
T' rocket was built usin' 4" PML
Quantum tubin' and a PML nosecone. T' fins were cut from .093" G10
fiberglass and will go through t' airframe and mount t' a PML extended
Quik-Switch 54mm motor tube. Ahoy! I cut t' fin slots myself by markin' t' tube,
drillin' a 1/8" hole at each end o' t' slot, and usin' a steel straight
edge and an X-acto knife. T' Quantum tubin' was only slightly more difficult
to cut than normal phenolic tubing.
A 10" section o' coupler tubin' and
3/16" plywood was used t' build t' avionics bay that will house a Missile
Works RRC2 altimeter. T' altimeter, by t' way, me hearties, was won in a raffle at the
LDRS 19 banquet. Well, blow me down! Ya scallywag! T' ejection charge holders were made usin' PVC pipe plugs
epoxied t' each end that will hold Robby's Rockets ejection canisters.
T' recovery system is a 20" Sky Angle parachute for t' drogue and a 52" Sky Angle parachute for t' main. Twenty-one feet o' tubular nylon for shock cords at each end o' t' avionics bay, along with Nomex heat shields and shock cord protectors.
After primin' and paintin' with gloss paint, shiver me timbers, I applied custom made vinyl graphics. Blimey! T' finished rocket weighs in a just under 10 lbs empty. Begad! T' picture (above and right) was taken at LDRS XX just prior t' a successful first flight, to 5,958 feet on an Aerotech K550.
