I recently saw two Kikka airframes at the Smithsonian Garber facility. The curator mentioned that one of the airframes, following aborted takeoff, was fished out of the Tokyo bay. It was later fitted with curious fairings over where the engines should be (see picture), but he could not tell me what the fairings where for.

Does anyone know? The only thing I can think of is flying qualities tests in powerless flight while towed behind another aircraft.

I saw the same Kikka during a visit to Garber some years back. Even at a distance, in a darkish, crowded hangar, the sheet metal work looked much too crude to serve any aerodynamic purpose. My thought was that someone tried to replace or hide missing components prior to some postwar display--the same way people painted swastikas on everything.

That's a possibility, and while I don't rule that out, my recollection is that the rear of the fairings ends in a streamlined shape. If you were trying to make something look like a turbojet, you'd leave a gaping hole at the rear.

My thinking was that whoever did the work had never seen a turbojet. They just had big empty tubes and tried to make them presentable--of course, it is just speculation on my part.

I remember the front of the nacelles as being covered by rough, irregularly shaped cones with small openings at the tip--a shape hard to reconcile with a serious attempt at fairing, especially if the rear of the nacelles are, as you say, closed. But it's been years and it was pretty dim in the hanger, so I could easily be wrong.

I know what you're talking about, regarding the lighting of that place. interesting bit you mentioned about front fairings. I can only hope some report or picture will be found in the archives that can clarify this.

Hi

We also know that a number of 2 seater variants of the Kikka were planned and a few Kikka-K variants were already constructed. I wonder if the Ki-201 would have had a two seater variant for training or reconnaissance purposes similar to the Me-262B.

Cheers

Hi Guys

My idea if what the Kikka-K would look like.

Cheers

Is it just me, or do several of those Kikka drawings look like made just by
modifying a Me 262 drawing, especially with regards to the fuselage cross
section ?   ;)

The images which look like the Me 262 are renditions of the Ki-201, which was to be the definitive Japanese version of the German jet.
