As far as building a Junior in two days, maybe, but I'd still think in
terms of 680 man hours as the substantial difference is fixed gear vs
retract. Two days is a meaningless concept without knowing whether
30-40
people were involved for 8 or 12 hour shifts.
I suspect that one Junior emerged from the factory every 2 days but surely
they must have spent longer on the line than 2 days. If for instance you
have 5 stations on the line and each airframe spent 2 days at each station
that is a total of 10 days on the line. Now if 3 guys worked in each
station
with two shifts that is a total of 5 (stations) x 2 (days) x 3 (# guys) x
8
(shift hours) x 2 (# shifts) = 480 hours. This seems achievable for a
simple
glider. I just cannot see how a sailplane of conventional construction
could
be made in an elapsed time of only 2 days when cure time etc is allowed
for.
If indead it is true that the Junior was made in 2 days with two shifts
then
this deserves careful study. Does anyone have a PDF copy of the Junior
maintenance manual ????
Janusz ... do you have any more info on this ????
I ve got only the user's manual, more it's in Polish only:

What exact info on maitenance You need? A total life of Junior is now 9000
or 12000hrs if I remember correctly, the mid-inspection interval is 1000hrs.
However, the shorp production process has been achieved so far only by the
SZD and the Grob factories.
The production process of Junior comprised od TWO DAYS in a SINGLE SHIFT
system, so one day in a two shifts, I have checked this. This was achieved
due to e.g far going integration of the elements of glider just like the
main spar which is simply a Z shaped layer of the glassfibre (if I remember
correctly) and using the molds which didn't need the pressure forced forming
of the fuselage in the molds (well I am not sure if I had translated it
properly into English). Simply the stucture could form itself when just put
into molds (less workhours needed). This technologo also allowed to use
locally produced the "STR" (it's a brand I believe) glass cloth instead of
the Interglass cloth, and also it was possible to employ low skilled
employees (which are also a lot more affordable) at the production line if
needed.
It simply looks that simple technology could reduce lots of costs. Junior is
a good example of the way we should follow. Apart from this, it makes an
excellent sailplane for these who just want to fly for fun.
I have no specific knowledge of the technology, so I can't say how it was
achieved, and for me personally... I think there should be some time for
finish too!
I know that factory won't say a word on this (I suppose so)
as it is their technology which they use, but if properly marketed the
Junior could make this what the World Class supposed to be - a glider for a
masses, safe, easy to fly, and affordable - all in one. By the way, I have
heard that Junior is produced under licence n Brasil, can anyone confirm
this information?
Returning to the previous post by mr Whiteley, the '55' is all glass, no
carbon inside, just the well designed glass design. No flapperons or flaps,
as it's a standard class glider, BUT Diana... it's carbon, and it's designer
mr Beres is one of the best specialists in using carbon materials here in
Poland. He runs his own business since he left SZD after it has gone bust
for a while:
