Request: optimal operational conditions and limits for HE 111

[SR-F_Winger]

Did anyone test out the limits in RPM etc. and would care to share?

Jumo 211F engine in He111-6

 

2600rpm 1.4 Ata Notleistung - dont overuse,1 minute

2400rpm 1.25 Ata Kampf...something - dont overuse,few more minutes (30max according manual)

2250rpm 1.15 Ata Normal continuous flight (unlimited)

Can confirm that.

I went a bit further:

(Notleistung takeoff) Full bomb load ( 50kg and 1x500 kg ), 60% fuel

~2400 RPM 1.30 Ata climbing up to 4km alt. ( ~15-20 min ) - no engine damage. 

I think 5-6km are possible to reach. Haven't got enough time to test it at the moment.

Awesome guys. Thanks a lot!

Can this thing takeoff with a full load? I believe I tried with 100% fuel 2x1800 and a I think a full bomb bay and manage to slowly stall after getting airborne at 200kph. It just wouldn't leave ground effect.

I doubt that He 111s routinely operated with that load. According to Wikipedia (not the best source, but it cites Karl-Heinz Regnats Black Cross Volume 4: Heinkel He 111) "Carrying bombs externally increased weight and drag and impaired the aircraft's performance significantly. Carrying the maximum load usually required rocket-assisted take-off". And 100% fuel is going to give an endurance of something over 8 hours - more than you are ever going to need in BoS.

 

Incidentally, you can't have an internal bombload with two external bomb racks - the second rack blocks the bomb bay.

I've just managed to take off with no wind, 100% fuel, and 2 x 1800 kg bombs - it is possible. The initial rate of climb (at around 220 km/h - full up trim) is only 2 m/s or so though.

yup i finally managed it haha I I don't think a full fuel load is 8 hrs. 30% didn't even get me 1. Auto bombing is hard.

I was training a little bit yesterday. You have to keep in mind the wind in m/s and direction.

Bombsight:

Set in on "view", then go "further" to spot target. Set up Airspeed, Alt., windspeed and direction.

Set bombsight on "auto" once target is straight in your bombsight's cross, open bomb bay and selct "auto drop bombs" ( or w/e it is called ).

Tried in 4 times in 3 km alt and is was not exactly precise, but close enought to destoy the selected target.

 

But is pretty hard to hit single AAs :/
