Aircraft Trivia Quiz

This should be a fairly quick one, especially for those Fw-190 afficianados.

On said plane, what was the cooling fan on the radial engined ones connected to? The propshaft or the crankshaft?

The cooling fan had a hollow hub, which was attached to the prop shaft.  The fan itself was driven by a reduction gear system.

Sorry guy's that isn't correct. The new builds of the 190 do show that to be true, however, I am going from a dvd I have on the 190 that has WWII footage and a direct frontal view of them turning the engine over from a dead stop.

Gear driven from the crankshaft at 3.12 times engine speed.

can we clarify please?

I gave one answer and the poster before me gave the other.  And you said that we both were not correct.

The hollow hub is indeed connected to the prop shaft, but like I said the fan itself is driven from a gear system, not from the prop shaft.  That is why I made the two statements, to clarify that the fan is not driven by the prop shaft itself.

In all fairness, I should have asked the simple question of, did the fan turn the same speed or faster than the prop. I found this while looking for  more info.

A remarkably compact installation, adequate cylinder cooling was obtained using pressure baffling augmented by a magnesium alloy fan geared to turn at 1.72 times engine RPM (3 times propeller speed).

From this site:

So in reality it isn't 'connected' to either shaft. I goofed again, sorry for the confusion guys. The DVD I have clearly showed the fan turning faster than the prop and I assumed it was directly connected to the crankshaft. I will try and be more careful next time.

Floor is free!

As the floor's free...

This aircraft was lightened, but, this resulted in a g-force issue.  An interesting, but sometimes uneven (and hence dangerous) solution was found.  To get around the sometimes uneven solution, a more explosive solution was found, which a ground crewmember unfortunately found about the hard way.  In the end the pilots were just told not to exceed a certain g.

Which aircraft?

I think we need a tip. Maybe the era or country of origin.

I think that the last person perhaps unwittingly gave a hint in his comment. I could be wrong.

juts a stab but i remember hearing something like this about the F-104.

I'm thinking it is the F8F Bearcat, which had explosive charges in the wing tips.

Mike

Ooops, sorry, bit slow to respond there! No, not the Bearcat, but, very close.  We are on the tip of the answer...

MQM107

I'm thinking it is the F8F Bearcat, which had explosive charges in the wing tips.

 

Mike

I have a side question. What were the explosives for?

When the Bearcat was built, it was felt that the aircraft could overstress the wing when maneuvering, so breakaway wing tips were designed and installed, but then apparently situations of having one tip break away and not the other created a more dangerous situatuion. So explosive bolts were installed to insure separation of both wing tips. In the end it was felt that the explosive wing tips were more dangerous than useful, so the whole idea was abandonned.

Best wishes,

Grant

I read it was the Hellcat, not the Bearcat.  However, as Bearcat is close, and, as there could be a difference on source information, I'm going to run with MQM.

MQM - over to you!  What do you have for us?

You can imagine the perplexed look on my face when told the Bearcat was incorrect. So much so that I just got in the car and drove down to the Naval Aviation Museum about 20 minutes away. I have a buddy who works there  and he showed me where they (the bolts) went. So anyway, this aircraft had (has) a unglamorous nick name of the Leaping Heap. Who am I?

Well there aren't that many A/C that can leap, so I will go with the H.S. Harrier?

You are correct Milair. Although I think that name applies better to the Yak 38. Your up on plate.

OK - I agree regards the Yak as well.

This aircraft was chartered during the Falklands war to the RAF, The RAF had previously operated & retired the type? 

Gosh, the VC-10.

I think it is the Short Belfast.

Borg R3-MC0

I think it is the Short Belfast.

You would think correctly;

ok, to stay in the UK, what Shorts design was used by the USAF?

Sherpa

It is indeed the Sherpa! Over to you Osher!

This British aircraft was designed to be built in larger numbers in WWII but was only built in limited numbers (60 or so I believe)  It was based on an existing airframe, but, had significant changes, based on an earlier Farman design, which ironically had been a failure, with input from the Americans.  The technology developed was then given back to the Americans.  Although this aircraft wasn't used much, it lead the way to the future for the allies.  What was the aircraft?

Gloster Meteor?

Martin Maryland.

Here's a clue: under it's original engine, it was reasonable, but, after just a few, a change was made to Merlin engines.  This gave a better than exepected performance.  The airframe was a pre-war design, but, in use pre-war to post war.  This unique version of the aircraft though had a unique interior, which also resulted in a unique looking front fuselage.

I've been searching all day, the only thing I can come up with is the Wellington. How about another clue?

I want to say Bristol Blenhem, but I don't think they ever had merlins did they?
