Manned Aerodynamic Reusable Spaceship. Presented by Douglas in 1962 for the Aerospaceplane (ASP) contest. Clearly, someone at Douglas had watched "When Worlds Collide" a few too many times. This was designed not as a true SSTO, but as a twin-ship formation... one carrying payload, the other carrying extra propellant. They would meet up at a speed of Mach 6.5, and the mission aircraft would be refueled. That would, undoubtedly, be entertaining.

This vehicle will be described in greater detail in an ASP article in the V2N5 issue of Aerospace Projects Review.

...One has to wonder if someone at Douglas hadn't watched When Worlds Collide just one too many times :-\

OKay, so you're going to pump large quantities of highly flammable/cryogenic fuel and/or oxidiser through a relatively small bore pipe bathed in the
aerothermal heating from a Mach 6.5 airflow??? ??? :eek:

cheers,
Robin.

That top one (and it's other views) looks pretty interesting.

I can just hear the ground controllers as they are watching:

"Ooooooh" "Ahhhhhhhh" "Ooooooooh"

Hmmm, that would make an interesting little CG project. Bodies of revolution and fillet-less fins = easy to model. I'm slightly confused by the engines, though. Are the inlets round or rectangular with a wedge shaped centre body?

I thought it might be a staring point. Before ventral fins became popular.

Hello all

See attached two documents... seems that "supersonic refueling" studies in 1959 considered the "wing tip to wing tip " method. Now what is intriguing, is that the exact same method was considered for Aerospaceplane and "hypersonic refueling" some years later - see the pictures in the first post here. Douglas Model 2235 was to use that trick.

Was there any connection between the two ?
