Title: Convair 880 and 990
Post by: ysi_maniac on October 12, 2013, 11:19:32 AM

Supersonic Coronado

Would it be possible to reach supersonic speed in a Coronado just with aerodynamic refinements. I mean without afterburners.

Wouldn't you need some form of area ruling?  Carrots, anyone?  ;D

Didn't the Convairs have carrots already?

Looks a bit like Myasishchev tried to make an airliner variant of their M-50 project.

As another variation in this, what about merging the wing etc from the B-58?

Yes that was my first idea. That idea existed in Convair.

But  I am thinking in moderately supersonic, about mach 1.2 or 1.4 Still an interesting advantage against 0.8 of normal liners.

Fair 'nuff

How would you reengine Convair 880 or 990 with modern high bypass turbofans?

The 990 Coronados had Whitcombe carrots on the trailing edges of the wings, but the 880s didn't.

As it was they were REALLY fast, at the time the 990 was the fastest airliner in the world. I had the pleasure of flying from Birmingham to Majorca in a Spantax 990 in 1979 but I think I was the only passenger aboard who appreciated the fact.  :)

Back in 1972, I flew one of Delta's Convairs (I think it was an 880) from New York-Kennedy to Houston Intercontinental (formerly Jetero and now Houston-Bush) and it was a very nice ride.
