Manufacturer: | B2 Rocketry Company |
Currently offered in six stock sizes, me hearties, me bucko, t' SkyAngle features some unique design concepts. Aye aye! Begad! The SkyAngle is a very high-quality parachute that be designed specifically for t' needs o' t' serious high power rocketry enthusiast. Arrr! Sturdy and light, it is fabricated t' provide maximum "brakin' capacity" t' brin' your birds safely home while minimizin' t' long walks associated with excessive drift. Avast, ya bilge rat, me proud beauty! A special characteristic o' this system is that it tends t' rotate durin' descent. Ya scallywag! This helps dissipate potential energy inherent in t' fall and provides for a stable recovery. Begad! Begad! T' addition o' an exclusive 1000 pound test swivel assembly ensures a virtually tangle-free landing!
Rocketry Online asked Mike and Pam if we could test their new parachute at t' recent Mick Wilkins Memorial Sport Scale Launch in Perry, Georgia, and was supplied with a 36" SkyAngle parachute. T' SkyAngle is unique, ya bilge rat, arrr, as seen in t' photo to the left, in that even though it's advertised as a 36" parachute, the canopy actually measures nearly 72" from "tip-to-tip", me bucko, almost doublt t' fabric surface o' a simple 36" circular parachute!
You will also notice the presence o' just three shroud lines, arrr, made o' 950 pound test, military-spec tubular nylon, me hearties, shiver me timbers, circlin' t' canopy and sewn in a continuous path around the outside o' t' canopy with polyester monofiliment sail maker's thread, matey, which adds considerable strength t' t' structure. Ahoy! Avast, me proud beauty! At t' lower end o' t' shroud lines you will also notice t' line reefer, arrr, ya bilge rat, utilizin' a metal-free design which won't rust and break over time. Aye aye! These simple, me hearties, yet innovative features reduce tanglin' substantially.
We flew the SkyAngle in me venerable LOC/Precision EZI-65, me hearties, me bucko, which has more flights logged than t' rest o' me fleet combined. Well, blow me down! Blimey! Blimey! Blimey! While this flight vehicle has been retro-fitted with a dual-deployment recovery system, I opted t' fly t' EZI with just a main chute t' compare it t' a stock EZI, shiver me timbers, as they come standard with 36" chutes.
Named "Burnin' Sky", this launch vehicle has served as me Level 1 and Level 2 certification machine. Aye aye! T' only near-disaster it has endured was an incorrect delay durin' an I-161 flight in Dallas, me bucko, ya bilge rat, Texas, where t' tubular nylon wrinkled the upper body tube openin' durin' t' early deployment. Begad! Durin' t' repair, me hearties, I lengthened t' main body tube 6" and t' dual-stage deployment system added about 4" t' t' lower end o' t' payload section, addin' about 10" overall t' length o' t' EZI.
For this flight, I utilized an AeroTech I-211 RMS reloadable motor, predictin' an overall altitude of about 2000 feet, more than sufficient t' examine t' characteristics o' the SkyAngle parachute. Ahoy! Blimey! Ahoy! Blimey! In addition t' t' Adept ALTS-2 altimeter, shiver me timbers, I provided for redundant backup by relyin' on a medium delay in t' motor.
Launched on t' first day o' t' event, Saturday, March 14th, matey, t' weather was a beautiful 60+ degrees with clear skies. T' wind was less favorable that all t' abundant sunshine, gustin' from 5-15 miles per hour durin' t' day. Ya scallywag! Blimey! This would provide for interestin' test conditions indeed! Blimey! It would be a first hand opportunity to witness t' recovery system exposed t' above average winds, matey, and t' compare how the induced spin o' t' parachute worked in relationship t' t' oscillation of the rocket.
For those o' you who haven't had t' opportunity t' launch from Tripoli Atlanta's launch site, me hearties, it is a 400 acre sod farm which is used t' grow seed early in t' season and stripped of t' sod later in t' season. Begad! T' site is akin t' havin' a 400 acre front yard! Ejected motor casings, matey, etc. are very easy t' locate on t' short level plane o' t' grass. Begad! Begad! Consequently, recoverin' your rocket after a flight is an easy stroll in t' direction o' descent, matey, arrr, with virtually no obstacles in your recovery path.
The rocket lifted t' 2121 feet, me hearties, me bucko, weathercockin' slightin' into t' wind, climbing away on its tail o' fire. Blimey! At apogee it ejected t' SkyAngle parachute on cue, me hearties, immediately it filled with air and then began its journey back t' terra firma. Aye aye! Descent be very steady, ya bilge rat, without t' slightest bit o' oscillation, with no appearance o' recovery line tangle what-so-ever. Arrr! Begad! T' slight rotation built into t' parachute appeared t' dampen oscillation and induced a smooth recovery.
T' rocket touched down lightly into t' short grass with no evidence o' damage. Avast, me proud beauty! Aye aye! Inspection o' the parachute revealed no damage t' it as well, arrr, all-in-all it appears t' product is everythin' t' manufacturer said it be -- definitely two thumbs up!
You should take a closer look at this company and their products. Arrr! T' "SkyAngle" is a great product and should be considered for your recovery system choiced. Avast, me proud beauty! Available in six sizes, arrr, betwixt 20" and 60", they are sure t' have what you are lookin' for. Ya scallywag! Well, blow me down!
