Ju-88, Ju-188, Ju-288, Ju-388, Ju-488, .... Ju-888

Will die without understanding this world.

Hmmm, well, can I ask a question?

Why did they go for the cockpit style they did for the 188 and thereafter? Pressurization? Aerodynamics? Visibility?

GTX-- I love the idea, and did a "carrier" Bf-110/410, but that was a "Doolittle Raider"-type that would be placed on deck via crane and only take off a carrier and fly to a land base, not really intended to operate off a carrier. The problem is the elevators. Even with folding wings, I believe a plane the size of a Ju-88 would have too long a fuselage to fit on a carrier's elevator. I am facing the same difficulty with my envisioned He-119 "carrier" bomber. I was trying to "invent" some sort of break-away tail that could be fastened back on once on the flight deck, but even MY imagination has a hard time wrapping around the concept (like, how would they treat control cables, etc?)


I am almost embarrassed to say I do not know the dimensions of a typical WW II carrier elevator, but they usually brought only ONE single-engined plane to the flight deck. Grumman's clever wing-fold meant TWO tightly-folded planes could be brought up to the flight deck, but I think the Avenger-sized aircraft was about as big a plane as could be handled. I know later, onboard the Forrestal-class US super-carriers, the twin-engined "Skywarrior" could be stowed, but I think the elevator size had grown sufficiently to do that.

Just a thought.
My mind is like a compost heap: both "fertile" and "rotten"!

D) All of the above.

You could do it by having a mechanism at the break that transfers forces via surface contact rather than a "locked" link. Something like:

The cables from the cockpit operate a "push one way, push the other" mechanism at the join.

The mechanism pushes another mechanism on the other side of the join.

The second mechanism then pulls another set of control cables leading to the tail surfaces.

That's the theory  - what it does to control forces and feel is anyone's guess, but I'll bet it's not good, at least not without LOTS of development work. Not light either......

Rather than have a "break-away" tail you can have a "swing" tail, with all of the elevator connections packed to one side where the hinge would be.

Or have a pioneering "all-electric" tail with the surfaces actuated by electric motors. It wouldn't be anything like as clever as modern fly by wire, but I think mid '40s tech could come up with artificial feel for the controls....

A folding tail would not that big a deal to engineer, heck they even use them on helicopters.

Nope, aircraft electrical generation and electric motor technologies of the period would not be
capable of providing the required power and speed.

Didn't the Fw191 use electrical actuation instead of Hydraulics or mechanical for majority of systems?

QuoteThere is another book on the 288-388-488

This one maybe?  Just ordered it anyway:



Given how important the Bomber B program was, I'm surprised there isn't more detailed information on it.  There is after all a 300+ pg book on the Ju 388 (on to buy list):

Lee,

Didn't you propose a Ju188 based Ju488 a while back?  I can't remember or find the exact post though?

Ok, what are people's ideas for:


  • Ju 588?
  • Ju 688?
  • Ju 788?
  • Ju 888?

The Black Cross books by Regnitz are English translations of his 'vom Original zum Model' series
and all are absolutely excellent.

I have the translated version of the Ju 90 book and the, not translated and probably never will be, volumes on the Fw 200 (the airliners not the bombers and the best book on the subject) and Dornier Do X.

My own early Ju188 based Ju488  - based on Lee's concept (but with single tail fin amongst other ideas):
