Cornelius XFG-1

[otftch]

This is a Cornelius XFG-1 expendable fuel transport glider. It would have been used for airborne transportation of fuel and towed behind bombers or long range fighters and cut loose when the fuel was exhuisted. Two prototypes were manufactured, with one crashing during tests. This effectively killed the project. Cornelius Aircraft corpoation went on to produce a couple more foward swept wing aircraft for the civil market.The kit is an old Airmodel vac-u-form to 1/72 scale. This guy was just to neat not to include in my collection.

Another 'out of the ordinary' subject - nice one. Certainly a strange little thing, and a rather odd concept too.

Nice Ed! You did a bang up job with that vac!

Nice work Ed!

 

[Wayne Little]

That's not bad at all Ed, haven't seen that one before!

WTF!? You constantly educate me, otftch. That was actually proposed to be towed behind a LR fighter or bomber? Was it supposed to be a small scale concept airframe? Looks too dang small for meaningful fuel content. I also assume the cockpit was only included during test validaiton for manual landing to minimize testing costs.

Off to Google/Wiki... again.

Here is some more info.....
The Cornelius XFG-1, developed under the project code MX-416[1] was an aerodynamically unusual aircraft intended for an unusual military role. George Cornelius had been experimenting with aircraft featuring differentially variable incidence since the 1920s.[2] His first two machines were otherwise conventional but the third, the Cornelius Mallard from 1943 was not, being without a horizontal tailplane and having low aspect ratio and strongly forward swept wings. Though very different in detail, the XFG-1 built on the Mallard experience. A 1/4 scale model of the XFG-1 was built for wind tunnel tests.[3]

The FG in its designation stood for fuel glider and its role was as a fuel transport. It was to be towed behind another aircraft rather like contemporary troop carrying gliders, but its two fuselage tanks held 564 Imp gal (677 US gal, 2,563 l) of aviation gasoline.[4][5] Unlike other troop carrying gliders like the Waco CG-4, the XFG-1 could be towed by modern bombers or transports at a cruise speed of 250 mph. Proposals seem to have included a piloted tow version behind a large transport, the glider landing loaded on skids having jettisoned its wheels after take off; or a pilotless version towed behind a B-29 bomber, disconnected and abandoned after fuel transfer was completed;[2][3] the intent of the scheme being for the glider to act, essentially, as a giant, winged drop tank for extending the range of the towing aircraft.[6]

The XFG-1 was a high-wing monoplane, its wing set far back towards its vertical stabilizer. The wing was quite high aspect ratio and of modest forward sweep. Though the earlier Cornelius aircraft had wings that had their incidence variable in the air, the incidence on the XFG-1 could only be adjusted on the ground, with two settings of 3° and 7°.[2][5] There was no horizontal tail. It had a simple fixed tricycle undercarriage and a conventional single seat cockpit; two examples of the type were built.[7]

Operational history

Two prototypes were built and 32 flights were made between them in 1944–45,[2] although the first was lost to a spin, killing the pilot. On many of the flights, but not the fatal one, the pilot was Alfred Reitherman.[8] The fuel glider concept was abandoned at the end of World War II.

Bizarre. Thanks for the post.
