Default OSC Pegasus paper model

Hello All,

I just found this (see: http://www.orbital.com/LaunchSystem...per_Pegasus.pdf ) downloadable, flying paper (110# cardstock) model of OSC's (Orbital Sciences Corporation's) Pegasus air-launched satellite launch vehicle (see: http://www.orbital.com/LaunchSystem...hicles/Pegasus/ ). With low-powered (13 mm mini motor- or 18 mm "A" motor-powered rockets), this Pegasus model could be carried aloft like the old Estes Firefly parasite boost-glider.

Thank you--those can change over time. I was just thinking--a "stick fuselage" OSC Pegasus glider (like the Estes Firefly parasite glider [the one whose wings and tail surfaces looked like--and may have been--from the Mini-Bomarc, making it a "SPEV boost-glider" if that was the case]) could fit closely atop a BT-20 fuselage with a Pegasus-like BT-20A nose cone, which could serve as a streamer-recovered booster. (A BT-50 booster with the similar-looking stubby BT-50 nose cone [the one used in the Estes Meanie kit, among others] could be used for a larger-scale Pegasus boost-glider model of this type; even larger ones could use the Big Bertha's BT-60 tubing and nose cone, or the Quest "Big Betty" [35 mm diameter, I think] tubing and nose cone.) Also:

If necessary for sufficient stability during boost, an extra, clear plastic ventral tail fin (for an original Pegasus model) or clear plastic "extensions" of the normal three Pegasus XL tail fins (which are evenly spaced) could be used. Such semi-scale models of the AQM-37 Jayhawk and AQM-81 Firebolt could be built the same way.

I made a BT50 based model using a cardstock plan with a foam core 'wing'. I used the vacu-formed PNC-50 from Apogee. With a couple sinkers glued into the nose, it flies great as a rocket. Simple streamer recovery. I didn't try to make it glide.

That sounds promising. Estes, Quest, or one of the smaller companies could produce a detailed scale Pegasus or Pegasus XL kit, which could--like the Citation Bomarc--be either parachute (or streamer) recovered, or could be a rear-motor boost-glider (with a rear-ejection, parachute- or streamer-recovered internal motor pod).
