Ushawks, Karen Bass, and Gavin Newsome are going to convert the Sylmar LZ into homeless housing.


Hello Doug,

The U.S. Hawks has not declared war on the SHGA, and the U.S. Hawks does not support homeless housing in the Sylmar LZ. You might be reading too many fake news sites (unfortunately, they are far too common in this sport).

Perhaps you are correct Bob. There is no war. I just misinterpreted the technical difficulties I was experiencing using the SHGA forum as a hostile act.
Last summer an arson related brush fire damaged my hang glider storage sheds/Green houses so anyone hostile is an immediate suspect.

The Spring 2024 volume54 number 2 USHPA Pilot magazine states on page 66: USHPA members rated H3/P3 and higher are eligible to incease their liability insurance limits to $1 million/$1 million....

Maybe this is an offering for you to rejoin. You could try and post on the SHGA forum and ask. This would also test if the technical difficulties exist for other users.

I am getting ready to order supplies to repair my telescopic hang glider prototype leading edges from amazon prime.

I noticed a spelling error from one of my previous posts.

I typed "Homeless housing" would be built in the Sylmar LZ.

That text should be replaced with "Bullet Train Tunnel".

This addresses the Microsoft AI saying the shortpack could be fragile.
from the hanggliding.org forum:
https://finsterwalder-charly.de/en/hang ... tures.html

"...Unbeatable light and sturdy
Thanks to high quality materials and a technically mature construction, the DHV-test runs were unable to damage the Fexes even by top speeds.
Years of hard usage in flight schools have shown, that despite the considerably lighter weight and the short pack possibility our Fexes are just as sturdy as any other glider on the market. All construction parts have proven their longevity. Thanks to their high quality used Fexes have a high resale value.

We use only seamless drawn tubing from 7075 T6 alloy with a stregth of 650 N/mm² of special dimensions prepared for Finsterwalder. Those tubes are eddy current-tested, mechanically polished and anodised internally and externally.
All Fexes are delivered with super light-weight airfoil AEROFOIL® and AEROSAFE® king post and A-frame uprights and forged, aerodynamically shaped fittings from avitation aluminium. .."

Finsterwalder could license the technology to Wills Wing in Mexico, import the glider to USA duty free using USMCA Treaty and transfer the technology to Moyes in Austrailia using AWKUS treaty and if Trump wins the election he will impose 60% tariff on Vietnamese paragliders.

Good notes, dhmartens!
--------------------------------------------

Consider nestable parts or telescopic parts, tapered parts, CF parts, optimized nestable ribbing ... over the Chanute-biplane direction; what might be done for busability on the direction?

We are on hold for the moment because Russia is using this movement to deliver weapons against Ukraine.

Advancing inflatables stays in the attention of this project just in case solutions appear from the inflatable world.
Take a peak at shapewave® for an advanced approach to making inflatables. Below is a quote from their website:
HAND HELD WINGS
Built with shapewave®, hand held wings can finally have an optimized aerodynamic profile and enhanced stiffness at the same construction weight as current LEI constructions.
Due to the even load spreading, canopy materials suffer less stress and are therefore expected to last for many seasons.

pressure class 0.20 - 0.35 bar

At this year's celebration of Otto Lilienthal's birthday occurring at Dockweiler hang gliding site, "empty-hope wing" showed up and was photographed in poses with sever hang glider pilots. I brought a transport case about the size to be used in some solutions to the 5-ft-or-less HG wing; I practiced the full bus transport and hike with the "empty-hope wing" in order to test the polite bus-carry and ease of the hike. Many ideas came up during the practice transport and ride. The ideas will all be noted ultimately in this discussion thread. Frank Colver breathed out an observation that was close to the following: "he's starting out with the case" .... instead of having the solution and then casing it. Of course, once a solution is materialized there will be effort to optimize a casing for tote.
See their technology comparisons: https://www.shapewave.eu/technology

===================================================
Carting or wagoning perfected for a solution will be very important so the hang glider pilot does not get too exhausted from the go-to and return-from site efforts. Aim to avoid excess mass, but get the tote system well balanced.
===================================================
Note about sail solutions: Dream winnings are forwarding zippered sail sections for several reasons: mod easy, repair ease, experiment ease, tote options.
===================================================
Note about solution comparisons: two-spars may have an edge for simple-sail bowsprit when accepting upper and lower rigging choice; the control of wing planes and ribbing position might give better aerodynamic results.
===================================================
Note to explorers: share now or later! :idea: :idea: :idea:
