Hi,

maybe Mr. Alexander Kartveli had many unknown Project in earlier period of his career ?.
 
The project depicted is not the 'Uncle Sam' designed and constructed
by Kartveli ,Thieblot and Cagniard for Mr.Levine.

Uncle Sam was an all metal , underpowered single engined prototype.

Perhaps the illustration shows a planned future concept for Mr. Levine
 
a bit more...

The "Uncle sam" was designed by Alexander Kartveli, Armand Thieblot and Edmund Chagnaird.
It was intended to set some long distance records so that funds could be raised for

'an even more ambitious 50 ton , 50 passenger trans Atlantic liner'

Eliptical shape of the wing would reappear in later Kartveli designed Seversky and Republic products.
Kartveli and his felloiw engineers has specified the use of a Farman engine, whit which they were familliar
but Levine,in a typical move, insisted that they use a Packard2A-1500 engine.
As a result , Uncle Sam, was terribly underpowered..

So far : Walt Boyne in "Wings" , June 1980. p.43.

The illustration found by Hesham shows the 50 ton trans Altlantic I guess..
 
OK my dear Lark,

and I was asking about if there was unknown Project in early period to Kartveli ?.
 
Hi

Edmund Chagniard was my grand father.

I recently found some pictures and data from his collaboration with Kartvely.

This wing project was devellop by Edmond Chagniard as designer and airplane constructor, and Alexander Kartveloff as technical engineer .

Plane was suppose to be produced in France but at that time they didn't had any serious offer except from Charles Levine ( Columbia Air Liners )
They travel in october 1927 to Long Island were they integrate the Uncle sam plane project.

Unfortunatelly 1929 crisis arrived and stop the project, so my grandfather travel back to france

Amazing and brilliant,thank you Lulu105,and welcome aboard.
 
So the term LCK-1 means the three names mentioned Levine-Chagniard-Kartvely No.1?
 
Hi Lulu105,

can I ask you of your grand father,Mr. Edmund Changiard had anther Projects or little known airplanes,not published ?,
and thanks in advanced.

his name is chagniard (and french surname Edmond)

Well he also participate to build the famous uncle sam. I have many pictures from its construction
My uncle will visit me this weekend : i'll ask him if he heard about something else...

I'd like to see a three-view drawing or other plans of the aircraft, if you have them. These huge commercial aircraft projects from the golden age of flight are among my favorite subjects.

I've picture from uncle sam plane

I'll open a new discussion on it...
 
Sorry to resurrect another old thread....

The Columbia Aircraft Corporation was an American aircraft manufacturer, which was active between 1927 and 1947 and originally founded by Giuseppe Mario Bellanca and Charles A. Levine.

An interesting proof-of-concept project for the company was the "Uncle Sam". Main participants were John Carisi as the engine specialist, Edmond Chagniard, French designer and constructor, and Alexander Kartveli as technical engineer.

The "Uncle Sam" was an all-metal single engine high-wing monoplane transport with an enclosed cabin and heavy V-struts. The sole example carried the US experimental registration of X305E with a c/n of 101. Pilot Roger Williams first flew the aircraft on 18th April 1929. It was powered by a Packard 2A (450hp), had a wingspan of 60 ft and had a speed of 125 mph. The aeroplanes radiator was built into landing gear.

Only the prototype was built for a planned future multi-engine version transoceanic transport to carry around 50 people (see first item in this thread).

The aircraft was built in 1929 and was sold at auction in 1931 to pay back hangar rent charges. The "Uncle Sam" and two other aircraft was destroyed shortly afterward in a Roosevelt Field hangar fire.

Reportedly cost $250,000 to build in 1929 it was auctioned off for only a fraction of that massive outlay.

Hi,


The Columiba Aircraft Corporation and the designers,Edmund Changiard and
Alexander Kartveli created the Uncle Sam,it was a transoceanic transport all
metal aircraft,with cantilever wing looks like a blended wing,and powered by
three engines,all details are in Les Ailes journal and in Aerofiles site;

Dear Hesham,

Personally I would rather see 5 engines because we see 2 cones at the trailing edge of the wings. For me it would surely be two motor shafts for two pusher propellers. And this would fit well with the power needed for a fifty-ton (metric?) plane... Did I rock it ?

Respectfully
 
I would second this opinion. Tried a reconstruction some years ago, and I chose 5 engines, too, though
maybe at least some of those five props were driven by coupled engines ? Compared to the Junkers
G38, which had 4 engines, but only about half the weight, not even 5 of the then most powerful aircraft
engines seem to be enough.

Agreed with that my dear Tonton-42.

Brilliant work my dear Jemiba,many thanks.

Uncle Sam 1929 = ChwM; 450hp Packard 2A; span: 60'0"; v: 125. Edmund Chagniard, Alexander Kartveli (P-47 designer), Armand Thiebolt (PT-19 designer). POP: 1 prototype for planned 50p transoceanic transport [X305E] c/n 101; ff: 4/18/29 (p: Roger Q Williams). All-metal; cantilever wing; radiator built into landing gear. Test-flown into 1930, but production of the plane, seriously underpowered, was cancelled. Reportedly costing $250,000 to build, it was auctioned 1/19/31, for only $750, but destroyed in hangar fire two weeks later.

I understand that this is not an easy matter. Onako, for the fullness of the story, would be eye-catching. I want to make drawings of A. Cartvelly's planes.
