Very remarkable news in the last patch!

Checked this for the Dora and some historical material was found. Here's an example reference: https://forums.eagle.ru/showpost.php?p=3631003&postcount=4 (although view the whole thread if you're interested).

 

Interesting but what does it say? Especially on how to employ the rockets?

Interesting but what does it say? Especially on how to employ the rockets?

 

There are two main historical references in the thread: https://forums.eagle.ru/showthread.php?p=3631003

 

The first is the Änderungsanweisung Bf110 Nr.230, which shows the mounting angle for the rocket tube (8 deg) with respect to the wing chord (2.5 deg). Although this for the Bf-110, it is effectively identical to the FW 190 (based on measuring it from photographs... but if someone has a schematic, please post it). This is thus a relative angle of 5.5 degrees with respect to the wing chord. Ref: https://forums.eagle.ru/attachment.php?attachmentid=187958&d=1529452861

 

In level flight (or at least shallow dive) the rocket launch pitch angle with respect to the aircraft's velocity vector is 6.5. (You can test this with the F2-external view in DCS).

 

The second reference is the Geschoßbahn (trajectory) plot (Skizze 2 E.Kdo/11.1943) and the accompanying table. Ref: https://www.deutscheluftwaffe.com/archiv/Dokumente/ABC/b/Bordwaffen/21%20cm%20Wurfgranate/Text/Angriff%20mit%2021%20cm%20Granaten.jpg

 

The sketch is for attacking bombers (also useful!), but the principle is exactly the same for attacking ground targets, which have a Eigengeschwindigkeit (closing velocity) of the velocity of the attacking aircraft. The table shows the fuze time (ZL) and the closing velocity. For a shallow dive in the 190, this will probably be 550 km/h. So that gives an Erhöhungswinkel of 6,8 at 500 km/h. If you use the same interpolation as the 4 second fuze (close enough), that's 0,1 sec per 50 km/h over 500 km/h. So, in our A8 example, that would be 6,9 deg. The rocket tube is 8 deg up from the chord, and an additional pitch angle of 1 deg... so about 9 deg. The difference is 9 - 6,9 = 2.1 (close enough to 2 deg). Thus if you aim 2 degrees up, you will hit a stationary target at just under detonation range. Note that the left rocket will fire first. There is also convergence, with slight cross-over at the explosion point. I tend to approach at 1 deg high, then dip onto 2 degrees aligned to fire. This keeps the approach manageable.

 

That is my interpretation of the historical tactics, and if anyone can supplement it with contemporary records, please do so, as I'd be most interested to read it.

 

 

That said, using this method is VERY accurate. I can put a rocket exactly where I want it, every time. I have far more success with the rockets than with the cannons or bombs in the A8 against ground targets.
