Austral Launch Vehicle
Hello All,
Here’s a Concept Scale prototype for an interesting “cross-over” model—the Austral Launch Vehicle (ALV, see: http://heliaq.com/ and https://www.google.com/#q=Austral+Launch+vehicle ). This mostly reusable, "3STO" (Three-Stage-To-Orbit) launch vehicle design utilizes a V-tailed or T-tailed rocket-powered first stage whose high-mounted, straight wing is stowed atop its fuselage during launch. After the reusable winged second stage separates, the first stage re-enters the atmosphere as a hypersonic glider and then (after slowing down considerably) deploys its pivoted wing. Then a piston engine (mounted inside the nose) starts, turning a propeller whose deployable blades are folded against the first stage’s nose during launch, and the nose tip serves as the propeller’s streamlined spinner hub. A small expendable third stage injects the payload into orbit. Also: A scramjet-powered second stage is being studied for the ALV. The studies also include clustering multiple units of the ALV’s reusable first stage around a conventional two-stage expendable rocket core vehicle (the "placeholder" core vehicle looks like a Falcon 9...), to increase its payload capability. (The propeller-driven first stages would be able to loiter near the landing runway so that the multiple first stages could land one at a time, then taxi off the runway so that the still-waiting first stage [or stages] could then land.) An ALV Concept Scale model depicting the three-stage, mostly-reusable version could have an electric motor-driven propeller with folding blades on the first stage (the scramjet-powered winged second stage model could use an EDF [Electric Ducted Fan]), and both winged stages could be radio-controlled. I hope this information will be helpful.

Looks something like the Russian "Baikal" flyback boosters, which also have rear fins that act as tail surfaces in recovery flight, and a swing wing that deploys to fly the booster back to a runway landing, under jet engine power, with the jet located in the nose cone of the rocket, running on residual kerosene from the rocket fuel tank.
