Figure on cost per hour plus overhaul,put that much in the bank for every hour flown,fly and forget about it.
We have a bunch of adequate motors,but nothing
"great",Zoche sure looked like a miracle,as do others
but natch on a plane yet.
An all flying canard surface such as found on
the wren,or robertson stol aircraft,should spice
up the performance on a three surface tandem
Make the first and third surface operate differencialy.Done right ,control forces will go
up with airspeed,and help to keep it in hand.
How about an abitrary reference point ,three feet from my center,find my bolt hole,extend
the line out to the same diameter as my reference,measure, compare to the same
radius as my bolt, repeat as many times as nesessary to get a grouping,throw out the outliers and average the rest.
I aint gona machine nuthin,just design and
make a pattern/file. For Class A+ machinists to follow.Get a test template made, verify the pattern.Email the file,and the part will just be waiting when I get home one day.
The figure of .006 play was referencing a dry crank with an extension,and yes is theoretical.
The point (well taken) is that useing the crank
center to locate the pins and bolt holes is prone to errors.
An adjustable arm bolted to the crank flange that could hold 2"pins of the size
I will get to drawings,and then start filling the
waste paper basket with those.
Right now I am throwing out ideas, and getting
Useing a doughnut/guibo on the flywheel and driving the small pulley will isolate the belt drive from the toroidal motion of the crankshaft and having a...
While I concur with the need to have gear sets
aligned in both dimensions to .001 or better,I am left with a quandry as to the value of measuring crank shaft run out when evaluating
Or is crank run out only a broad hint, and that hanging anything like a belt drive pulley off of a crank...
I dont know Pops, you tell some great stories.
Some are gems.
One in particular where you describe a day in the shop ,setting out to do one thing and then
getting sidetracked a dozen times doing some thing else that needed done.
Math and the ability to focus are central to building an aircraft...
Ok then one principal is that each hole you need can be treated as a point,on a circle,centered on your crankshaft.
And then each hole can be measured for distance to each other.
If any three holes line up in such a way to make
right angle triangles,so much the better.
Plenty of other good...
You almost got it,they designed while Hittler
provided a reminder of what they were about.
And as a war contingency they designed as to minimise the impact on factory floors,where thousands of ordinary men and women came to work to pound rivets while the bombs fell.
No time or energy to...
l will ask for a slight extension on this diversion.
The numbers posted about the tensile and ultimate streagth in the article linked suggest that the syretching that does occur,happens at
loads beyond other materials currently in use.
Yes ? no? and that the implication is the thermal...
