Convair XB-46 - hmmmm Martin XB-48 - a jet powered B-26?These
airplanes, along with the later Martin XB-51, show just how difficult
it was to find a place, for, among other things, the engines.
They were installed in the same places that piston engines had
been installed, or buried in the fuselage, or hung from it. Martin XB-51
Some major design decisions
A 35 degree wing sweep was selected as optimal for performance - about the sweep widely used in follow-on airplanes.
The B-47 hung the engines from both short and longer wing pylons - a configuration used universally ever since.
A swinging motion called Dutch Roll was solved using an active rudder control system called a yaw damper.
High speed nose pitch up resulting from outboard wing boundary layer separation was solved by vortex generators.
Aileron reversal due to flexing of a flexible wing was solved by using wing spoilers for both roll control and as speed brakes.
(Although designed and tested on the B-47, spoilers found their first home on a Boeing airplane on the B-52.)
Long landing field lengths were addressed with tail mounted ribbon parachutes, and a powerful anti-skid braking system.

The B-47 also pioneered airborne refueling technology widely used in subsequent airplanes.
And much more.......
Some more pictures of the Museum's B-47
Our airplane - 35 years -- waiting for greatness...............
WB-47E 51-7066 arrived at Boeing Field in October 1969 marking the last flight of a weather Stratojet.
The Museum, as we know it, did not exist. It would be a long time for her to achieve the prominence she deserved......
longer than she was in service.....but, .....all good things come to those who wait
For, literally, decades, she sat in an obscure corner of the Boeing military ramp.......
forlorn, but, nonetheless, saved, and awaiting her place of honor
Today, she has arrived at her rightful place in history
Glorious, simply glorious
