LS-4 ? What about 1-26 ?

Brad,
It's starting to sound a bit like an HP-24, only smaller.
Cheers!

Finally you don't need to point out that the above is somewhat
idealistic. I
am very aware of this but unless we look to the future, challenge
ourselves
to do better and make significant progress in the direction of costs
and
affordability we will not have a viable sport. Someone has to start to
do
the dreaming if we are going to have any hope of solving the problem.
Anyone
share that vision ?

Well, since I seem to dwell a lot in the idealistic sense when it
comes to glider design/building I'll chime in.

My vision of my idealistic glider would be a self-launcher. It would
be something between a TST-10 and an Apis 15m.

The engine installation would be an engine on a stick, I would look
into using the extension/retraction system the Russia AC-5M uses,
electric start would be good.......since this engine already exists
with the MZ-35, I would probably choose this engine.....although it
seems 2-stroke technology is booming these days....just look at the
power plants being developed for the powered parachutes........the
Cors-Air Black devil would even work for what I have in mind. Probably
there are even more out there that I am unaware of, and I have done
lot's of homework on this subject.

The mission statement for this sailplane would not be for racing, it
would be tailored towards recreational flying.

It would look sexy; D2 type planform with a modified D2/V2 type
fuselage shape.....because I think these are archetypes of modern
sailplane design......here is where I end my similarities.........I do
not need a racer, or a heavy ship, or a ship with all the modern
accoutrements......these are the refinements that make a glider so
expensive. I believe the R & D that goes into these ships is cutting
edge: airfoils, boundry layer devices, tooling......this all adds up,
as it should, and pilots who buy and fly these masterpieces have every
right to be proud and have high expectations for performance and
quality.

Now.....back to my dream machine. This ship would be built using wet
layup technolgy, it would use a lot of carbon, the wings would be
sandwich construction and the fuselage would be carbon with ring
bulkheads and stringers. It is somewhat true that the cockpits of
these "lightweights" are sparse, but I believe with proper use of
Kevlar and a combination of integral seat and cockpit longerons a safe
and lightweight fuselage could be made.

I would strive to make the parts count as small as possible to
minimize the cost in time and $$. A set of molds could be made if
there was interest in such an idea, to facilitate making multiple
bits, but there are other tried and true manufacturing methods a guy
could use to make it a one-off and not incur the expense of hard
tooling......the trade off is hours of labor to fair the outer
surfaces to your level of quality.

I really believe that an elegant, nice performing ship is possible to
manufacture and with diligence could be done and sold for a price a
lot of us would find appealing.

Well, that's my dream of a west-side sailplane.

Cheers,
Brad

Funny about that...

Seriously, I do have a 13m ship on the drawing board, and I'm holding
a project number for it. It will use a lot of the shapes and internal
parts I've already developed for the HP-24. But it'll stay a paper
airplane until either a) I get at least one or two -24s in the air or
b) the prospective 13m market shows signs of heating up.
