Originally a concept for a VTOL military liaison aircraft, considered for exec role, centre fan lift.





Two SR.177 based concepts.

Nice one Jon - good call.

Looking at alternative/early bizjet concepts, I always wonder whether the 'normal' layout we have nowadays, with two podded engines at the rear and a high tail, is really the best, or is it just the convention that everybody's used to? Burying the engines in the rear fuselage would almost certainly reduce drag, just as it does on a fighter jet, but would the increased speed and/or decreased fuel consumption be worth the extra maintenance headaches? How bad would those be anyway, with proper detailed design?

The main issue with buried engines is replacing them with newer,
improved, more efficient engines as engine technology improves.
It's a hell of a lot more expensive than developing a new nacelle
design.

The very minor difference in drag isn't worth it for aircraft that don't
spend long periods of time in the speed ranges where it makes a
difference, as with fighters etc., which is the reason that strut mounted,
podded engines, became the standard configuration for commercial
aircraft, and will remain so for the foreseeable future.

Length: 38' 6"
Wingspan: 40'
Height: 13'

Based on the data it seems that P-51D wings would be a perfect basis.
Good catch.

Looking at the drawings I can't help wondering what they were smoking or drinking on the Isle of Wight back then. 

There's not a single Saunders Roe design that was in any way conventional, and it seems that went for the civvie designs as well as the military ones!

More SARO, two of the different configurations studied during the P195 & P202 design
process.


Four engines buried in the rear fuselage, tiltable for short takeoff.



Indeed you are correct Kit, From Sea to Air by Tagg & Wheeler has 18 pages
of post-war concept drawings, with two to eight drawings per page.

Apart from everything else, doesn't putting the engines in external pods make things a bit quieter inside the plane?
Also less vibration.

Seems an appropriate place to leave this screenshot from Twitter...

Bottom of this page from the Flight archives, model of Lockheed trijet concept for a successor to the JetStar. Same configuration as the TriStar with underwing engines and S-duct in the tail but on a stretched JetStar fuselage.

Handley Page HP.113.  One of my favourite early bizjet designs, tidy looking.  I believe it eventually morphed into the Jetstream.





Earlier boundary flow research aircraft with Canberra style goldfish bowl canopy.
