Evening Ken,

First look in of the day, I didn't have a chance to look for this last night and I find its still here, so another quiet day by the look of things!

I think it's an Albatros L 68A ?

Yes it really does appear very quiet at present. Hopefully its just a lull.

Evening gents. Too slow I see, just finished a kit plane, although this looks like a hammer and nail job as well. Dare I say it, European Trevor?

Lots of questions here mate.

Parasol wing with another wing between the undercarriage legs? Pilot somewhere behind the engine in a fuselage that appears to be supported between the wings with wires/struts?

Finally, did she fly?

(Long shot, but Ken had "Ellehammer" in the cryptic thread recently - I wonder if...)

That'e a pretty good analysis mate! The lower wing joins the triangular wheel fairings, the top wing has only a single post from each undercarriage fairing to support it, and yes the fuselage is supported entirely by the wire bracing, now have a closer look and see an unusual feature that will make it easy

Did she fly??, there's no good evidence to say she did!

Nothing to do with cryptic clues!

Dunno mate. Two engines? Pusher-Puller arrangement?

Two engines? yes (you can see them), but only one prop as you can see. The designer claimed that one engine could be cut in flight, but seeing that it never flew !

Well, no idea mate, as usual. I first thought it was a prehistoric version of the Fieseler Fi-333 where the long undercarriage allows you to pick-up/deposit a load, but I guess the bottom wing would prevent that.

Gotta go. Don't stay up too late mate...you've got an early start tomorrow, I'm sure.

Just looking in at coffee time to see what's going on! Nothing much it seems , so a little clue to add to my previous hints, it had a quite an unusual (possibly unique) engine layout with two Gnomes and a single four-bladed propeller!

Hi Martin, I see you on the list; where are you now, still away?

No perhaps frontlefthamster, it is the 1911 Coanda Biplane

Coanda's second aircraft which appeared at the Concours Militaire (at Reims), where it raised some sharp dispute even to this day, it shows what remains... and what was given up from his first machine of 1910 (which appeared on SC, page 30 in 2008). What was given up: the turbopropeller ("turbo-propulseur" (sic)) and the wooden wing-skinning, as well as the wooden fences to ease the regular fluid flow. What remains: the aerofoil section, the structure, and the general shape of the fuselage. All very interesting, but built somewhat differently.




Links below to the earlier "Jet" of 1910 and very interesting information of the man himself. His aeroplanes may be long forgotten, but they pioneered many new ideas and the discovery of the "Coanda Effect" will give his name a degree of immortality in the field or fluid dynamics!

Hi Trevor!

Two motors driving a single prop through a diff?

Yes, still on the move. Arrived Mumbai this morning at 01:00 and leaving for home tonight!

Hi Martin,

You're quite right about the diff, but just too late as I expect you'll have seen by now!!

I've just finished the construction and packing of two new machines that are off to Mumbai tomorrow with two of our guys (or one if the other's visa doesn't turn up later today )!!

Have a good trip home mate

Unfortunately courtesy of a desperately slow internet today not had the opportunity to look in until now
Good call on the Coanda 1911 frontlefthamster....quite an impressive looking aircraft for the period.

Taking advantage of the OH, here's a somewhat different looking machine:

Evening Ken. Looks like you painstakingly silhouetted the French Givaudan?

Well, not painstakingly....just found a suitable image and darkened it over and over, then touched up some of the tatty bits

Yes it is of course the rather unsuccessful Givaudin "aircraft: of 1909.
