Default Skybolt ALBM (many links!!!)

Hello All,

Below are numerous links to photographs & videos of, and information on, the Douglas GAM-87 (later AGM-48) Skybolt Air-Launched Ballistic Missile (ALBM). Also, at the bottom of this posting are links to two model manufacturers who produce scale models of the Skybolt!

Only a small number of the solid propellant Skybolt ALBMs were launched from B-52 bombers over Cape Canaveral during the missile's short and controversial lifetime. The Skybolt came in at least three versions--a single-stage test variant with a long, rounded-tip conical nose cone, a two-stage version with a short conical nose cone, and an apparently rare two-stage version with a long, rounded-tip conical nose cone.

A pretty good Sport Scale model of the Skybolt (the two-stage intended operational version) could use the Estes Yankee kit's short conical plastic nose cone, a short length of BT-20 for the second stage, a length of BT-50 for the first stage (with a BT-20/BT-50 balsa reducer), and an Estes PNC-50K (the Alpha III plastic nose cone) for the Skybolt's drag-reducing tailcone that was jettisoned during the air-launch process. Here are the links:

That Skybolt is definitely a cool choice for a build.
I can envision having two different NC configurations to fly it with.
That tailcone arse-end with the extra fins is dynamite!
Hmmm...

Indeed! The tailcone definitely has multiple possibilities for flying scale models of the Skybolt (please see below).

The two-stage Skybolt versions could even have *live* second stages, using gap-staged upper stage ignition (which would *also* permit streamer or parachute recovery of the first stages, by using rear-ejected first stage motor mounts/vent tubes!). The flared conical Stage1/Stage 2 interstage adapter (or a portion of it) could serve as a conical stabilizer for the second stages. (The full-scale, two-stage versions of the Skybolt *may* have utilized the flared conical interstage adapter as a combination high-expansion upper stage exhaust nozzle *and* conical stabilizer, as the Aerobee 300/300A's upper stages did with their conical interstage adapters.)

For extra "Flight Points" in scale contests (*and* to give a Skybolt scale model a little extra "oomph" at launch), it could be launched with the tailcone *attached*, which would "pop" the model into motion up the launch rod at ignition (similar to the way a piston launcher does)! The tailcone's rearward-pointing tip could simply sit on top of the launch pad's jet deflector (with a small square of recovery wadding under the tailcone's tip to prevent the exhaust residue on the jet deflector from marring its paint finish). If a Skybolt scale model was launched from a radio-controlled (R/C) model airplane in flight, the hollow plastic tailcone would be ejected at ignition (just like the tailcone on the actual missile), and it could be recovered using a small aluminized mylar streamer, which could be packed between the model's motor mount tube and the inside wall of its body tube.
