Designed as an unarmed reconnaissance aircraft, the Heinkel He 119 never went into production, precisely because of the lack of weapons. The following link provides a complete report with information and photos of this fabulous airplane. I hope you enjoy the article and count on your visit.
Interesting, as usual. An elegant Heinkel design, with very good observation capacity. However, it would have been quite a big target - unlike smaller spotter aircraft - and the lack of armament would not have helped. Clearly, fighter escort would not have been practical in the type of mission contemplated for this aircraft. Thanks for posting, JR.
I meant: in this aircraft the cabine and the propeller are almost the same thing, I don’t think it’s a good solution of reliability especially for an operational aircraft (which this one never has become).
I’m afraid I still don’t quite grasp your point, the reliability of which part of the flying machine do you mean ?
While the motor is placed internally at the CofG I have seen no documentation reference overheating even though airframes 02 to 08 had a semi-retractable rad installed to increase cooling during t/o & gaining alt.
Nor have I seen anything to suggest that the extended propshaft induced severe vibration which can affect handling and airframe life.
So without meaning to appear obtuse I still fail to understand how the positioning of the prop/engine should affect the reliability.
Not being an aeronautical engineer, I give it a shot:
Vibrations!
I suppose the propeller axis in the glass/cockpit compartment is not fully supported as a closed engine compartment would be…i.e. you can always put a larger coaxial supporttubing around it, but you are not free to have it supported anywhere you want, because interference with pilot seats or instruments…whatever…
Probably also not a big problem during regular flight, but once the shit hits the fan (something breaks down, a bullet/particle hits the prop axis) and the axis start vibrating (even only a little bit…) and all stress design calculations are void.
The obvious clue that there IS something wrong with it, is that you never see it implemented again…
