B-70 supersonic cruise follow-on

[Skybolt]

Browsing in the NASA technical reports I found a score of wind-tunnel tests regarding a supersonic cruise bomber that seems linked to some unknown B-70 follow on specification from late '50s (report is from 1961). Some photographic reproductions of the models are practically unviewable, but there are some designs. One is clearly derived from the XB-70 shape, other (one posted here) are different. Hope someone has more infos.

This is the design more similar to the B-70. Differences are clear, however

Hi Skybolt. If possible, please include details of the NASA report you found it in, it will help others help you finding more info.

Regarding NASA technical reports, research isn't always for a particular program,so it helps to know for example if it was a joint study with a particular company rather than a NASA-only study.

Yep:
"An exploratory investigation at Mach numbers of 2.50 and 2.87 of a canard bomber-type configuration designed fro supersonic cruise flight" RM L58B28 dated April 15th 1958 classified as confidential

"Low speed investigation of effects of vertical tails on the static stability characteristics of a canard-bomber configuration having a very thin wing and slender elliptical fuselage" NASA TM X-436 dated January 1961 classified as secret.

In his 1995 book Dark Eagles, the late aviation writer Curtis Peebles notes that the alleged "Brilliant Buzzard" mothership is actually the Rutan Long-EZ homebuilt aircraft, and it is possible that alleged mothership for the rumored "Blackstar" spaceplane dubbed SR-3 in the AWST article was actually be a B-1B with its wing fully swept back, because the B-1B can fly above Mach 1 when the wings are swept back at 60 degrees (much like Curtis Peebles considers the triangular aircraft seen over the North Sea in August 1989 to be an F-111 with its wings fully swept back).

Both seem to be generic NASA research configurations rather than company designs.
