Intake issue already explained on pg.2.

...Engine will be uncowled (why hide all that detail) so there will not be an intake in the conventional sense.  The centrifugal compressor will draw air in through the inlets like those seen here (mesh covered) on this Rolls Royce copy of the original Soviet Klimov design.

Not sure how powerful the "suck" would be but Biggles might like to ensure he is strapped in.

"Radial flow"? 

Compressors of that sort are usually referred to as "centrifugal" flow and have been for a very long time and well before the invention of the turbo-jet engine. I don't believe I've ever seen one referred to as "radial flow" in any of my books about engines, aircraft, ground vehicle or marine, piston or turbine.

Hmmm, yes.
Very good technical description Rheged.


Having removed the jigs and offered up the engine I realised the main mounting point for it could be a pin fitted between a hole drilled in the back of the engine and the original rotary motors boss which is moulded on the back of the firewall.  This means that the engine subframe doesn't have to actually mount the engine securely, just look like it does.
This is a good thing.

Wonderful !!

Engine subframe roughed out.  Needs a few fillets on the corners but it's basically done.
Now to move on to the tail.

Every time I see this I smile.. it is a great wacky idea.

I really do like that engine, as you allude to... it would be quite useful in a lot of builds

"Bertie" Biggles asked "is that my armchair from the mess?"
"Yes old chap."  Bertie polished his monocle " The Professor said it was better used here than it was supporting your jolly old backside in front of the fire"
"That's debatable.  But why is it attached to that length of rail wth what look like a couple of pairs of roller skates?"

That looks scary Fred...love it 😅

Are you going to paint the engine cage so that it looks like bamboo?

Are you going to paint the engine cage so that it looks like bamboo? 

I am now.  Excellent idea Jon.   

[zenrat]

Airframe modifications are now complete and what little PSR that is required (mostly on the cockpit nacelle) has begun.  Carefully for this is one fragile build.
The straight sections of the engine cradle have been painted and look like either bamboo or over-ripe banananas.


"Bertie."
"Yes Biggles."
"Is that bamboo?"
"Bamboo?"
"Yes.  On the frame holding that, whatchermacallit, jet? engine  Is that bamboo?"
"Absolutely old bean.  Absorbs vibration according to The Professor.  Clever chap.  Remember theArt Deco Aluminium coffee service Mlle Yvonne used to use to bring us our coffee in bed every morning?  Well he melted it down and cast the fittings that holds the jolly old Chinese sticks."

This gets better every time I look at it ...............and it was an amazing idea in the first place.

Agreed and the size still gets me ..I'd destroy that if I hiccupped 
Great work Fred 👏 👍

[zenrat]

Thanks folks.

Have you thought that maybe I have really big hands?

The Professor engineered a gap in the rear bracing for the jet exhaust.
