Interesting report on a G-14

Of special interest is the engine boost limits.

(1) On deliver flights or test flights after an engine change, after take-off do not exceed 2,100 r.p.m. and 1.05 ata of boost.  If possible duration of flight should not exceed one (1)  hour.  Watch oil pressure.

   (2) For the first five (5)  hours, if possible do not exceed 2.300 r.p.m. and 1.15 ata boost.

   (3) For the second five (5) hours, if possible do not exceed 2.600 r.p.m. and 1.30 ata boost

   (4) After ten (10)  hours, the aircraft may be flown if necessary without limitations other than those laid down in current instructions.

"After an engine change" being the important part. All engines needs to be run-in, before they can be pushed to operational power levels.

Stating the obvious but you omitted the "On deliver flights" part.

Considering the number of Allied a/c in German airspace, delivery flights and break-in flights must have been nerve racking for the pilot. How long a flight time from Augburg to Holland and France at 1.05/2100rpm? (Augsburg > Paris ~600km, Augsburg > Deelen(Arnhem) > ~550km)


Did you read the report? Of further interest is the time limits for the different boost pressures.

On delivery flights or after engine change the engine needs to be run-in. Why is this a surprise to you? These aircraft would not be used operationally until they were run-in, and full power could still be applied, but at a serious cost of wear and tear on the engine, and increased risk of malfunction. The skies over Germany in early-mid 1944 was not that full of allied aircraft, and those that were there were up high protecting bombers.

The time restrictions were not a surprise either, and have been posted many times before. What new information do you see on that site?

LOL, no surprise (done it many times) so why are you still harping on the obvious. :rolleyes: :(

I did not say over Germany but German airspace. There is a difference. German airspace includes France and the Low Countries. :eek: Considering the Allies were swamping these areas with a/c  in preperation for invasion, re-placement and re-engined a/c  would be not that safe. Now what after mid 1944? The 8th AF was almost flying un-molested over Germany itself.

Time restrictions > to re-fresh some peoples memory.:)

New info? Well the trim and flap wheels were made of wood.

What does that have to do with anything in AH? Do you expect us to have to run-in the engines on every aircraft before we play? If not, why is this information "interesting" ... it's a GIVEN that engines needs to be run-in. Have you never bought a new car?

However you still ignore that fact that the engines could still operate at full power in an emergency, however the engine would have to be replaced again and overhauled. These boost restrictions are to prolong the engine life, and to assure nothing is wrong before operational service with the aircraft.

Ah poor little Sholzi is all upset. Who stuck the burr in your knickers?

This is the Geneal Forum > A/C and Vehicles forum. Many threads have been non AH related. :) Not necessarily anything to do with AH. Not everyone is as knowledgable as you.:rolleyes: :) They might not know what was involved in breaking in a DB605 engine. Besides that, it is a British report on a G-14.

No I don't ignore the fact that the engines could be run at above the break-in boosts and rpms, in an emergency. But as you say the engine would have to be replaced and that is normally an eight (8) job for 3 men. As if the 'black men' did not have enough to do.:rolleyes: Changing tires, batteries, regular maintainance, polishing the airframe, interupted by air attacks, etc, etc. What was the supply situation? Were engines readily available? Or did you forget the transportation system was breaking down?

As I said before, I have 'broken in' many engines, specific > the race type, so you can stop harping on the obvious.

What made you think I was upset? *lol*

We all know the Germans lost the war. You're just repeating things that everybody already knows. This discussion is of no value.

This is somewhat off-topic, but...

Is the G-14 better than the G-10?

VERY INTERSTING. Even the G14 had 200 rounds capacity in the 20mm magazines.

  "None of the guns had been fired and its was found that the ammunition tanks had not been completely filled.

 

                                        Tank capacity    Rounds carried

   20 mm.        ...            200 per gun    ...    150

  13 mm.        ...            300 per gun    ...    275

The Revi 16B gunsight was used."


AH now gives us 200 rds in F4 and G2. It seems also we should have vthis option on G6 and G10...

Well Scholzi, you are the only one repeating ones self, ad nausium.:rolleyes: Sounds like you are upset because your supermen could not do the job. :p Now put the muzzle back on that long snoot.:)


Take a hint from the last 2 posters.:) They seem to like the link, except for your manure. One even makes a comment about an application relevent to AH.:eek:

That link has some interesting info in it Milo.  But GScholz has a point...I'm kinda wondering myself why you picked the engine break-in procedures out of all that.  That's like worrying about the breed of cows used for the seat leather.

Anyway, cool link.

Actually Milo I think your emphasis on the need to run in brand new engines carefully in order to ensure long engine life  is kind of mundane, was this supposed to be significant info? Is it supposed to a new attack in the rearded series of 109/spit/enine/prop/fuel efficency threads between you and isegrem?

But thanks for the cool link anyway...
