What WW2 Russian aircraft engine had an unusual design and what was it?
Hint. It came in at least two versions. It design also had something in common with radial engines despit being a V type engine.
Modelling is something we never perfect. We should never quit learning new tricks and be willing to share what we have learned on our own.

Sorry nope. It was made in at least two different sizes.

"Had an unusual design" is perhaps a little loose? But, with that clue ... the Dobrynin VD-4 was an X-configured engine with air cooling. Is that it?

Sean, not what i was thinking of. Hint-- Its unusual design has roots in radial engines.

Hi Darrell
I may well be wrong, but this question reminded me of an engine that's always intrigued me since reading Vladimir Kotelnikov's book "Russian Piston Aero Engines" - I.A. Uvarov's 1600 hp Circular Engine, which was apparently shelved when Germany invaded the USSR.
All the best

Sorry Rowan that is not what I was thinking of. Another hint it is a V-Type engine.

Hi again Darrell
I missed the V-Type clue earlier - but reading questions properly has never been my strong point!
How about the Pavlyuchuk-Burov Enngine?

Hello Rowan, not the engine I was thinking. I can't believe I came up with a stumper. Hint --It was used on aircraft designed by the same bureau that came up with the killer aircraft of the Korean and Vietnam wars.

Hi again Darell
LOL! I though I had all the ingredients there with a radical V-type engine constructed with bits borrowed from radials and inlines.

Yes it is. The engine had articulated connecting rods. This gave it a stroke of 7.48in on one bank and 7.74in on the other bank giving a displacement of 2,847 in³.
Over to to you Scott

I have no idea what any of that means ! LOL
Ok my question :
In 1987 American Airlines was able to realise a saving of $40,000pa by removing a single item from all of its aircraft.
What was that item?

If it were the US Air Force I would say a toilet seat...
However, given the timing I'm going to go with ash trays.

No not that one
I think they just banned smoking but left the ashtrays in place to taunt the smokers!

Yep that's the one. They removed a single olive from every salad served in First Class, saving $40,000 ..... that's a LOT of olives!

Of course when people talk about this event, they neglect to count the cost of all the Management Studies, Planning Meetings, training sessions and change implementation that had to happen to make the change permanent. None of that is without cost, and probably ate that whole $40 000.- and more.

Kind of a trick question Jessie... the first Supercosnic "airliner" was a Douglas DC8 that broke Mach 1 in a dive in 1961. The first commercial Supersonic airliner design was the Boeing SST, and the Tupolev TU144 and Concord were the two successful "operational" Supersonic transports-- I think Concorde was the first. but the first commercial airliner to achieve supersonic transport was that old DC8.
