Ok! This one has been on my mind lately for some reason, so here goes!

Here are the clues:

1) Innovative aircraft designed to support Naval operations without an aircraft carrier, established a notable “first”.
2) Two engines.
3) The concept behind it’s use was based on a late WWII Axis design.
4) It was a member of a particular “class” of aircraft with three unique features (for the time).

Name the aircraft, Convair XF2Y SeaDart
the “first”,supersonic interceptor seaplane
the Axis design concept, ???
and two of the three unique innovations incorporated in the aircraft. 1 The aircraft took off and landed on a pair of retractable hydro-skis
2 The aircraft was fitted with a set of dive brakes on the lower rear fuselage which also doubled as water brakes and as a water rudder while taxiing on the surface 3 The aircraft was fitted with a set of dive brakes on the lower rear fuselage which also doubled as water brakes and as a water rudder while taxiing on the surface


Enjoy!

Darrell, sorry, no, not the answer, but you’re getting warmer. Again, some of the features of what I’m looking for are subtle. In fact, the Sea Dart does share at least one of those features, as well as some other operational “commonality”.

The last two pages don't work for me. Anyone else with the same problem?



They seem to be covered by the “reply/comment blocks”, but your response went to the right place. I select the page number (215) from the colored background posting on Kitmaker. You are in the right place, maybe an editor can shorten the pages at the bottom of the block. But I’m not sure anyone is paying attention. This subject has been a rather long one, and I notice not very many new folks are “playing” anymore, seems it’s just the same five or six of us over the last few pages. Time to retire it?
VR, Russ



OK, somehow I've got it work. I don't think the thread should be retired - it will retire itself anyway if there will be no players. Maybe we should make it more attractive in some way...?

Nope, not a drone. Time for another clue I guess: Initially piloted by a USMC Reservist, who had some unusual assistance at first.

I’ll give you another clue: The Axis design concept never made it to the prototype stage.

Wild, wild guess - some form of jetpack?

Nope, no “Rocketeers” here. This is an aircraft, piloted, that actually flew, originating in Axis ideas, with a few contemporary (for the time) features (and a few not so contemporary features). The concept technology was fleeting though, and wouldn’t be seen again for nearly 30 years in a different form, but even that concept was preceded by another form in a different country altogether.

I’m sensing we’re hung up here on one or two points— 1) Axis (as in German), and; 2) power-plant. Both points are not widely known about this unusual aircraft. What the Germans couldn’t do, this aircraft actually did.

I have a feeling it may be some sort of hovercraft, or something that uses "Ground Effect" enabling high speed at very low level.

Cheers

Nope, not a hovercraft or ground effect craft. This is an aircraft, which actually flew, has several “operational concept ancestors” existing today (though not of the same design or manufacture), with two of these “ancestors“ actually been used in combat operations, and are still actively serving.

Time for two more clues: 1) The aircraft in question was cancelled in favor of more “conventional” jet aircraft, and partly due to handling characteristics and pilot training requirements. 2) Look at the original posting again—especially the “designed to support naval operations WITHOUT an aircraft carrier”. What type of aircraft can do that today?

The Convair XFY Pogo?

Israel, you’ve got it! Over to you my friend! But before we go, here’s some interesting facts on the XFY-1 Pogo:

1) Based on research conducted by the Germans in developing a point defense VTOL fighter, namely the Focke-Wulf Triebflugel ram-jet wing point defense fighter concept, Convair and the US Navy developed the Pogo as a fighter capable of operating from small ship platforms without requiring an aircraft carrier.
2) The first flights by LTC “Skeets” Coleman were made in a airship hanger, tethered and assisted by a second pilot manning a winch.
3) On November 2 1954, Coleman made the first ever transition of a fixed wing aircraft from vertical to horizontal flight, while in flight. He would make several more flights to follow up.
4) The Pogo was powered by two Allison T-38 turboprop engines, combined with a massive gear box to operate two 14ft contra-rotating propellers. This was called the Allison YT-40. If you look closely, The Pogo has two separate exhausts for each T-38, there is no other outward indication of two operating engines.
5) Besides it’s unconventional landing gear and powerplant , it has a pilots seat on gimbals to allow it to be flown in both vertical and horizontal attitudes, and with a 52 degree Delta wing, it was the only Delta-winged propeller driven aircraft of its day, and became part of the Convair “Delta family“ (XF92, Sea-Dart, F-102, F-106, B58 and Pogo).
6) The pilot had about 25 feet of rope in the cockpit to climb in and out if the Pogo had to land away from support facilities. It was fast too— exceeding 300 mph.
7) The Pogo’s legacy lives on in aircraft like the AV8 Harrier, V22 Osprey, and now the F35, which operate on a similar VTOL/STOL concept. (There were others too, like the Hiller X-18). But the Pogo was first to accomplish what the Germans only dreamed of.

Here’s the story from the Smithsonian:

Over to you.

Which cargo plane was the first to introduce a swing-tail design for easier loading?

Ok, this should be relatively easy....

The Antonov AN-22 a very large prop driven plane. However, it's prop blades are eclipsed in size by what aircraft?

Hmmm...I'll give it a shot-- but I think more definition is needed. The Link-Hoffman III failed German WWI bomber had a 22ft+ diameter propeller. But I think the largest propeller ever is the V22 Osprey's 38ft diameter "prop-rotor"--does that count?

Thanks Gary, I was expecting a longer break. Here in the States, when we play (American) football, the defensive players always like it when the offensive line plays longer, that means the defensive players get a longer break to rest (can you tell I just finished watching the Kansas City Chiefs play the San Francisco 49ers?). But now, I guess I’m off the bench and back into the line. I have a question in mind, but need to do a little more research to make sure I’ve got my facts right. I’ll post tomorrow.

Ok, here’s the next Aircraft Trivia question: We know WWII started in September 1939 with the German invasion of Poland. But the US didn’t become a combatant in the war until December 1941. Do you know the date of first US aircraft attack on an enemy vessel as a combatant? Please give the aircraft type, date and location for this one. Neutrality Patrol doesn’t count. Bonus point if you can name the aircraft unit.
