1946. Anybody can help?[/font]
 
I'm not sure, is this it? ???

Interesting.... an American glider version of the German Arado Ar-232?

It's not, but it's quite an interesting image nonetheless. Will have do dig deeper to find out what it is.
Meanwhile, I've merged the posts about the XCG-19. You can now see a three-view arrangement of it further up in the page.

Just found it. It's the J-19 "Skyway Express" proposal by the California Aero Glider Co., Inc., of Los Angeles.

Interesting bit of info is that the J-... prefix in the above design indicates the type was designed by Volmer S. Jensen, as can be seen here:

Ha! We already had the J-19 on the forum without knowing it (along with the VJ-21). They can be found here in the "Patents" section:

1) Attached below is the article from Aviation News  dated August 1945, featuring photos not previously posted here.




2) Also, from the June 1945 issue of Aviation News is the following article, which sheds a lot of light on the project:

Quote

Jet Takeoff Planned for Glider Designed to Carry 10,000 Pounds
Cal Aero Glider expects completion of civilian model by 1946; price set at $65,000; designed to takeoff in 500 feet when grabbed by twin-engine tow plane.

Jet takeoff is planned to make practical a 10,000 lb. payload transport glider designed by California Aero Glider Company of Los Angeles.
Release of military restrictions that have been imposed on the design since January 1944 has resulted in the announcement by A. V. Marchetti, company president, that construction of a civilian prototype is expected to be completed early in 1946.
Marchetti estimates that production models can be sold for $65,000.
Preliminary specifications indicate that two, and possibly three, fully loaded gliders might be "snatched" and towed successfully by a two-engine tow plane, such as a C-47, C-53, C-46 or Lockheed Lodestar, with the gliders launched and brought to cruising speed by jet assisted takeoff units.
Heretofore the utility of heavy cargo gliders has been minimized by the problem of taking off from reasonably small fields.
Provision has been made, in the design, for installation of three jato units under each wing to enable a 500-ft. takeoff. Contact of the tow plane's snatching hook with the glider tow rope will close a switch firing the jato units.
Plywood construction is proposed by the glider's designer, Volmer Jensen.
A quick-loading feature is the use of four light-weight cargo stowing bins which will be attached to loading boards that will slide into position on roller racks installed on the floor of the fuselage. Locking pins in the racks will secure the cargo containers once they are in position.
Plans for the transport glider (J-19) are from the "future shelf" of California Aero Glider Company, which was cited in AVIATION NEWS of October 18, 1943, as an organization unique in its readiness to "stockshelve" its various projects while maintaining financial independence through enterprises offering immediate returns.
To minimize capital assistance that will be brought into manufacture of the civilian transport glider, which will represent an investment of $150,000, C.A.G. has converted its Los Angeles plant into a furniture factory and has opened a small factory in Temple City, near Los Angeles, for production of its "Penguin" pre-flight trainer.
Since opening, the Temple City plant has produced 150 "Penguins"; sold to schools and airport operators, and is in production of an additional 100 at this time.
"With profits from our 'Penguin' production, and furniture manufacturing we should be able to complete the transport glider mockup within a few months. Actual construction of the prototype should be completed within five months after construction begins," Marchetti said. Still on the C.A.G. "stockshelf" are projects for the commercial production of an advanced pre-flight trainer (J- 16) and a gas-powered sport sailplane (J-10). Several J- 16s were produced and delivered to the Army on an experimental order. An experimental J-10 is expected to be in flight by the middle of this year.





Model of Proposed Transport Glider: Shown are models of California Aero Glider's proposed J-19 transport glider, emphasizing clean lines and construction simplicity. Three jato units under each wing are proposed to facilitate fly-away pick-up. Quick loading is a feature of the proposed craft with four cargo units as standard equipment. Mounted on cargo platforms they slide into position upon roller tracks on the fuselage floor. Note the single-boom mounting of control surfaces.
