The Ongoing Mystery Aircraft Thread Part Deux.

[lefty]

You got it, Rob, S.E.4 she is. Moses' photo shows the original inverted-vee gear with the wheels at each end of a leaf spring - this, unsurprisingly, was soon substituted by the more normal arrangement in my pic.

When you resurface, old boy (I do hope you are pacing yourself ?) we look forward to a new horror........

sticking to a theme ( and because I can't get a good pic of the one I wanted)

4-bladed props on hollow spinners and tailskid...

Attachment 46043

I'd imagine less of a challenge than the last

[Moses03]

Looks to be a Beardmore W.B.2.

Edit: Might be away for a bit and feeling pretty sure about the Beardmore. Moving along with another 4-blader. Please press on if ya know it.

Boulton and Paul P.9

Still smarting at not getting a rare chance at a Scottish aeroplane (the Beardmore) !

Here's something completely different -

[wout]

Hi Mike,
the Saunders Aircraft Corporation (Canada) ST-27/28 modification of the DH Heron. Could your photo depict the only ST-28 with the larger cockpit windows (and reportedly the only new built airframe)?. Although..... are the props 4-blade (ST-28) or 3-blade (ST-27)

[lefty]

It's the only prototype ST-28 - C-FYBM-X - and those look very much like three-blade props to me, Walter, although production models were to have 4-bladers as you say.

Here's another pic.

[srgalahad]

I really MUST get on with scanning all my old slides... the ST-27 was part of my late teens and I have pics dating back to the arrival of the first pre-conversion airframe. Nice to see one I wouldn't have to research to identify

[wout]

Mike, thanks for the nice pictures of the ST-28. The bigger cockpit windows are evident.
For the new one, photos possibly do not exist or are somewhere in a safe.
This PoC/Technology demonstrator is said to have flown in 1986 (my guess is 13 August 1986). There is quite some info on the net, but NO PHOTOS

Citation meets Starship.. hmmmmmmmm

[Moses03]

I think you might be chasing a ghost Walter.

Some discussion here:
http://www.cessnacitationforum.com/f...showtopic=1796


Page 60-61 of this study has drawings of said Cessna.

So, Kevin does not name the rumoured Cessna Advance Turboprop Test bed, but it's included in his links.

Since many others have already come up empty, I'd be thinking this was hidden deep in the landfill, in spite of heresay about "photos". Between the horrendous development costs of the Starship and the Avanti struggles, it's no wonder Cessna kept lips sealed tight.

In today's world there is a bit more 'successful espionage' as pointed out by the pics of the test hack single-turboprop Cessna Mustang http://www.avweb.com/eletter/archive...ll.html#203559

[wout]

The sketch indeed depicted the alleged/rumoured Cessna ATPTB.
May i invite Kevin to draw the next straw?

[Moses03]

Morning all. New mystery is served-

[srgalahad]

Nice one Kevin... sneaking into my backyard to grab pics! (somehow the pics ended up in the Canada Aviation and Space Museum data bank -- and NONE on Aerofiles)

The Adkisson SJ-1 Headskinner

"The wings were from a 1946 Luscombe 8, cut and re-formed into the gull-wing configuration, while the cabin and forward fuselage section were formed of steel tubes. A Luscombe tailcone was attached to the aft end of the steel-tube frame, and standard Luscombe tail surfaces were used (with their tips squared off). Cessna spring-steel main landing gear springs were used. They planned on using a Warner radial engine of 125 or 145 hp, but settled for a 65 hp Continental with Beech-Robey controllable propeller in the initial installation."

Right on. And before Wout could sneak in.
