Heinkel He-116
« on: February 14, 2017, 09:24:12 AM »

Developed in 1936 as a mailplane for Deutsche Lufthansa, the Heinkel He-116 made use of design features of the He-70 and He-111, particularly the elliptical wing and tail surfaces. The aircraft was originally to be powered by four Hirth V-engines producing 500 hp each, but theses were not available in time so the 240 hp Hirth HM 508 was substituted. Eight civil aircraft were built with the designation He-116A-0, the first making its maiden flight in the summer of 1937. two were purchased by Manchurian Air transport and made their 9,530 mile delivery flights from Berlin to Tokyo between the 23 and 29 of April 1938, in a time of 54 hours 17 minutes. Another was modified for record breaking, with uprated engines, a wing of increased span and area and provision for possible rocket assisted takeoff equipment. Its designation was He-116R and it set a distance record of 6,214 miles in 48 hours and 18 minutes, beginning on the 30 of June 1938. An He-116B long range high altitude recon variant was also developed in small numbers, the last two civil aircraft being converted as prototypes. A total of 6 were produced

Each aircraft of the aircraft of both series comprised a standard He-70 fuselage with gunner positions faired over as well as a shortened and symmetrical glazed nose section much like that of a He-111. The wing was an enlarged version of the wing fitted to the He-112 with nacelles and mounts for four Hirth engines. The inboard nacelles carried the standard He-111 landing gear. The aircraft stayed true to the dimension of the He-70 including the same span as an He-111H-3 despite the different wing.

Never heard of it. It'd certainly make good eye candy if someone makes it. I think I  could work it into a single mission.

Produced   1937–1938 ...................... Number built   14

Well, what do I think ? ... (IMHO of course)..... this is just another 5 minute "wiki special" requesting several months work ...  but ... if we can agree an hourly rate for the job, I'll make it ........   ;)

...or you could try here....

.....on second thoughts though and joking aside, for all the use it would get as easy target practice, it is probably better suited to a "franken" He-111 project....

GJE,

My thoughts exactly! A franken should suffice, plus, you could add some small arms to it for fun.

And by the way, this is not from wiki at all. I have a whole library of aircraft that I have collected over the years. This info comes directly from there paraphrased of course.

That's all well and good. But, do you have detailed information about the Hirth engine performance parameters? It's a prototype aircraft with likely little usable information left at this point in time. It will likely be difficult to even remotely accurately model.

It was a complex aircraft, one to admire for sure. But, getting it in game will likely be an immense challenge at best. I'd love to see it, but it's difficult enough to accurately model much more produced and well known aircraft. This one seems to be a ghost of history. Much of the detailed engineering information likely died with the Third Reich. Sorry for the rant. I respect and admire all requests. Just trying to be realistic about it.

Yep, that is right.... plus, to be "correct", it would have to remain un-armed ... and of course we would need to know exactly how many rivets were used..........  ;)

I will provide the performance parameters but GJE the number of rivets may be a bit of a problem.

Again, nothing that can't be found on Wikipedia. Modeling engines, in game, requires more than that. Sure, someone could probably take a shot at a crude flight model. But, my point was that there's probably little to no information about how the engine performed across an altitude range from say 1000 to 7000 meters.

Unless you have more information, modeling this aircraft is a stab in the dark. Maybe there is some info, as it seems the Siebel Fh 104, Kesselring's aircraft (and other prominent officers of the Luftwaffe), used the engine. But, that was early on in the war. Any other relevant information may be lost to the war.

But, I must admit, both the Heinkel 116 and Siebel 104 are elegant aircraft that I would love to fly. Sadly, they seem to be obscure relics of history.

P.S. Nice engine photos!
