Winch Experts wanted

I am looking for a small group of professionals and folks with
practical experience in designing and building a glider launch winch.
My preference would be mechanical engineering types with power
transmission experience, Diesel engine/truck mechanics, Fabricators,
guys that know a thing or two about truck axles and maybe someone with
an insurance/legal background.

The purpose of putting this small team together is to come up with a
design for a safe, reliable and cost effective winch, which could be
built by a group of amateurs in the USA using commercially available
parts without a whole lot of modificatons.
There are no commercial ties to anything or anybody, nobody gets paid
and the design/ideas would be available for the asking.

So, who is up for the challenge?

How about a "Monster Garage" episode to turn a Dodge 3/4 ton with Cummins
engine into a glider launch winch.

they will probably want to add a rocket launcher or mortar onto it as well
to shoot down the launched glider to make the program sell better .

Couldn't be worse than the hot air ballon Tracker (or whatever it was)

The time it would take to explain to these mental bottom-feeder what
the thing is supposed to do with the "what? Glider? No engine? =
Booooring, Dude!' would exceed the build time or my patience!

But seriously now, any takers?

I really think this idea has merit.... but should we also consider lowering
the wing loading so that the horsepower requirements are much less? I also
think that the future of soaring is rather bleak without winch alternatives.

It's called Aerotow....... and what's wrong with winch? 1500 ft easy with a
decent field for under 1/3 the price of a 2000 ft tow..... ;-)

My statement was very confusing... what I really meant was without the winch
I think that we will be in troubles down the road for affordable tows....

And in part I do think that we have taken a wrong road with high wing
loading. for example with the Monarch we are able to tow it aloft with 160
lbs of tension at a speed of about 15 mph with a wind down the runway of
about 10 mph. This requires a very small rope and small horsepower.

See the article I posted in the Marske Web site on power requirements for
launching developed by Jim Marske.

But whatever I do think that your idea of developing a winch is a godo idea.

Nothing better than runing 125 kts between clouds with a 50 kg/m^2
wing loading in my ASW-27 after a $2 winch launch on my club's 280 hp
Diesel winch. vbg

I'd love to see a winch design that uses a 100hp or less engine,
can be easily bolted on the back of an old pickup, and has engine
and parts that are low maintenance and (especially engine) easy
to acquire (either locally or via shipping).

Alternately, how about a "spare tire" that is really a winch drum.
a stable sturdy "jack" and some way to route the cable
to ensure it winds up nice.

Might not work (thoughts of side loads tipping my car
over come to mind!), but it sure is fun to play with the
thuoght!
