My dear PaulMM,

with all respect,why we put this topic here ?,it was built only as a prototype,the better place is the Postwar section.

I hadn't seen this posted here before and so I thought I'd post it for the benefit of anyone who hadn't seen it before.

Not having the benefit of an education in aerospace, what is the meaning of the V Limit Design and V Max Design lines on the first envelope chart?

Hazegrayart has put out this interesting what-if video about the B-70 being used as a launch aircraft:

Alternate concepts for the XB-70 ranged from cargo and personnel transport, supersonic tanker and reusable launch vehicle to name a few. Some topics have enjoyed brief coverage in previous publications, yet most of what you will find resides in the archives of the Air Force Materiel Command History Office, a research facility located at Wright-Patterson Air Force Base in Dayton, Ohio. Research revealed a variety of gems in these archives, many a simple mention or illustration in an obscure report while others came from archived materials supplied by the manufacturer.

i’ve never posted this in here until now because it’s been a while since mydads put it together. but like the title says, this is the rough model of the Valkyrie that NAA brought to the pentagon to pitch the XB-70. my great grandfather worked for NAA and worked on the XB-70 project. he took this home one day when they were cleaning old stuff out of the office. pretty neat piece of history

the model that North American brought to the DOD to pitch the XB-70

Hazegrayart has put out this interesting what-if video about the B-70 being used as a launch aircraft:

I checked the XB-70 dimensions and tried to extrapolate the size of that big belly fairing as seen in the video. Would have been huge: 8 feet deep by 80 feet long. Maximum width near the 6*J93s : 30 feet; and probably 15 to 20 ft near the air intake.
Imagine the rockets to be rolled inside that belly, to be dropped beyond Mach 3.

The XB-70 would have been one huge bomber that is for sure Archibald, it is a pity that it never got built because of the MIG-25 Foxbat. But even so they would have countered the threat with the F-108 which in itself was a beast armed with huge GAR-9 or AIM-47 missiles.

The weapons bay doors would have to be re-designed. The two prototypes used a single large door which unlocked, lifted then actuated as one single large unit I think aft. In some of the books I have on the XB-70, this door design did not work for M3 flight.
