Did Mr. Hewson go on to design the YF-32?

Ah, but, the leading question.....do we know if it ever actually flew ?
Thread Starter
Many thanks!!
Don't think it flew - he's a concept designer (who did the QF 380 interior) not an aeronautical engineer - from his website:-
"Inspired by his lifelong interest in aviation, Marc set out to create a small jet-powered airplane that would restore excitement to the experience of civilian flying. This concept jet is named after Lord Kelvin, the nineteenth century physicist and mathematician known for his research in thermodynamics and absolute temperature, and the main character of Andrei Tarkovsky's film Solaris, another source of inspiration.
For Marc, the Kelvin40 is a very personal object, resulting from his obsession with the technology, materials, and processes that derive from the aerospace industry, where precision is of foremost concern and technology is constantly changing. He also believes the jet engine to be one of greatest inventions, unsurpassed to this day.
In aviation, form follows function and so Marc created an aesthetic object that is a direct result of the mechanical requirements of aeronautical design. He involved himself in all aspects of the design and production of this concept jet plane. Its wingspan measures almost twenty seven feet and corresponds directly to its length. Likening the plane to a sculptural object, Marc emphasised the customised elements such as the handmade panels that were carefully adjusted and riveted over the course of a year, the deep blue plush upholstery, and the red detailing at the air intake of the airplane that alludes to a mouth."

could have been a BD-10 if they'd ever tried to build it .............

I would call him a stylist, rather than a designer. An industrial designer integrates functionality with aesthetics (and manufacturability, if they're really good). A stylist sticks a skin of a fashionable kind on top of the working parts. Newson styled a camera for Pentax which was universally panned for its ergonomics (and its toy-like looks) and only stayed in production for a year.

The Kelvin 40 was discussed on Secret Projects back in 2007, plenty more photos!

I think you could ask the same question of the B-47 and the B-52
PDR
For the B47 & B52 it was a design trade-off. The aircraft were so long that any significant rotation would have required very long undercarriage legs, with attendant issues for ground dynamics (let alone weapon loading, maintenance and hangarage). So they designed the aeroplanes to NOT rotate - take-off flap gave them sufficient lift coefficient to just lift off "flat". You can see the side-effect of this when a B52 does a low pass in landing config. It's travelling faster than the normal over-the-hedge speed so it has to fly with the fuselage attitude several degrees nose down.
You wouldn't make this kind of trade-off with a small aeroplane on a relatively long undercarriage - aside from the difficulty in rotation it would be severely directionally unstable.

and the B-47 often required a lot of JATO to get off at all

Brilliant design but optomised for flying - not landing or taking off........................ and they built over 2000 of them.......
