Thought I knew pretty much every Miles project but once again this proves that the more one thinks one knows, the less one does!

Thanks to Tophe (though he no longer visits here) and hesham for sharing this.

The shape of this flying wing patent reminds me the "boomerang airliner" project from Flight 1946

Just a note: The third picture in the first post appears to be upside down.

The feature that is the subject of this patent is a tailplane that normally sits flush with the lower wing surface but extends when the flaps and UC are deployed. The purpose is to counter the strong pitch-down effect on a flying wing when the flaps are lowered. An alternative canard arrangement is also described. It isn't strictly correct to refer to it as a twin-boom.
I doubt that the flying wing itself was a true Miles project, just a sketch to show the extendable tailplane in operation. It looks to be a generic concept based on Northrop and Lippisch designs. The timing of the patent coincides with the setting-up of the Tailless Aircraft Advisory Committee by the Ministry of Aircraft Production, Miles probably patented the idea quickly to establish priority in case the committee suggested something along these lines.

Actually I'm going to amend my comment. A further Miles patent was for a hinged wingtip that they say was particularly suited to tailless aircraft, so it appears that they may have done a little work on flying-wing-type aircraft. I wonder if there is any more information hidden away somewhere?
