That there is a pretty spot on drawing...looks good +D

Wow, i didn't know the automatic pull-out system also had an auto-throttle component.

It's amazing how technologically advanced some of these birds were and most of all, it was all based on ingenious mechanical solutions. I stumbled upon a translated Ju88 manual today, linked in another post in these forums, which i promptly downloaded and spent some time reading. It's incredible how much automation the luftwaffe birds had in an age where digital computers were non-existent.

In the Ju88 for example, the supercharger automatically dropped to low gear when the pilot throttled down to assist him in reducing speed and it kicked back into high gear when throttling back up, based on a manifold pressure thershold. However, it was still clever enough not to kick into high gear when in lower altitudes.
RPM and prop pitch control was automatic, but the pilot could fine-tune the RPM values to stay within operating limits and account for inconsistencies between different engines, mixture was leaned automatically based on two different profiles and so on. Some pretty amazing engineering for the time, especially if we consider that it was all analog-sensor based.

I'm not sure it did. I think there was a checklist posted some time before that stated the pilot had to reduce power and close the radiator before initiating the dive. After pullout, he had to increase power and open the radiator fully. However, the air-brake system changed the pitch trim for the dive, released the bomb, and initiated pull out at a pre-set altitude in case the pilot blacked-out.

Correct me if I am wrong (and I am sure someone will lol), but wasn't the bomb actually attached to the rail? It was swung down prior to release as I recall. Yes?

Uhh, isn't that what the above pictures show?

The purpose of the "Pull-Up" device,

The elevator trim tab, which are used with the extension of the dive brakes,
goes back into their normal position at the bomb release.
Doing so, the trim tab initiates the "Pull-Up" manoeuvre from the dive.

Thanks Romanator, I missed that picture!

Well I guess it is solved then.

But is it true that the dive brakes retracted automatically when the bomb was released? I know from IL2 that the trim function works.

I read somewhere, not entirely sure, that the pilot had to push some kind of button to make this happen prior of bomb release.

Not the way that it was described as I interpreted it. The rail was not there for a guide, the bomb was attached to the rail and lowered prior to release.

Damned ingenious design really.

Does anyone know if the rail was always there? Or was there some unfortunate pilot somewhere who discovered that all of a sudden he had no propeller?
