Пару слов о гиперзвуковых летательных аппаратах. Планирующий крылатый блок «АВАНГАРД». Полёты во сне или наяву? (ч.1)
...Начнем с концепции waverider 'a ( волнолёта, волнового наездника ) Теренса Нонвайлера ( T. Nonweiler ). Он совершил прорыв, предложив не бороться с ударной волной при гиперзвуковом полёте, а «оседлать» её .

A week ago I had my third emergency detached retina surgery. Earlier today the surgeon conducted a one-week post-op exam and said I'm healing fine with everything looking good...so far.
The surgeon deliberately put a gas bubble in my eye, so I can't return to the mountains until that bubble is gone...in 4 to 6 weeks.
Once I get back home, I will do a few minor things to the glider, then assemble it again for a full-power taxi test.
I need to cultivate more patience....

#Conway's game of #Life is entertaining and worth looking at. Simple rules produce complexity, for instance the #glider, a figure which migrates across the board or space, and the glider gun, which spits them out.
The #vonNeuman machine conceptually makes more of itself. See the #monolith in #ACClarke's #2001aspaceodyssey or perhaps #saberhagen 's #Berserkers #SciFi

Delivery day for the oxygen cylinders!
I got help loading them in the truck when I picked them up at the delivery point in Alamogordo.
Back home, I'm alone and the unloading was slower and deliberate. Fortunately, I only had to lower the cylinders off the bed. Raising them would have required a ramp or other equipment.
I got them into the garage before the next monsoon rainstorm.
I need to make a wall rack to hold them upright, safely, securely. I think I need to get a 20-foot stick of 1-inch square steel tubing from the world famous Basin Pipe and Metal.
Can I make an air liquefaction plant?

The glider fuselage has been wet sanded.
It's time to for final buffing.
I did some experimenting this morning to get a feel for process and especially process control.
I had two different polishing pads. Would they give different finish quality?
Would a grid of black Sharpie help me keep track of buffing progress?
(Don't worry about the Sharpie. It doesn't stain the polyurethane paint. I can wipe it away with a solvent like acetone.)
Either polishing pad gives similar results, and buffing until the Sharpie grid is gone appears to be a workable control technique.
Water beading on the buffed surface is another indication of progress.
On areas with complex, and especially concave curvature, I'll buff by hand.
I'm not trying to do a fantastic job on the fuselage, but I'll gain experience before I do the critical stuff: the wings.

The glider fuselage paint job has been scraped to remove drips and runs, and also to cut off the top of all the orange peel bumps that cover the entire surface.
I had to experiment with making a scraper tool. It required constant sharpening.
I have transitioned to wet sanding with a dual action polisher to remove the rest of the orange peel, but I had to experiment a bit to get a process and system. That's because I can't see the progress of sanding of a white surface that's covered with sanding water sludge. I will probably draw a grid of lines over the fuselage that allow me to monitor progress.
The final photo shows light at a glancing angle across a sanded test patch (fuselage belly...I don't mind screwing up here). I see no signs of orange peel, or larger ripples/waviness.
I think I can transition from this sanding job directly to rubbing and polishing compound.

Installing the flaperon on the glider's wing.
https://en.wikipedia.org/wiki/Flaperon
It's a full-span flaperon, in two halves. Each half is almost 12 feet long.
Each flaperon half has 8 hinges made of a pintle/gudgeon pair. (1st photo)
https://en.wikipedia.org/wiki/Pintle
https://en.wikipedia.org/wiki/Gudgeon
When installing the outer flaperon half, I also have to engage two sets of pin/sockets that ensure the two halves move as one unit. (2nd photo) (Each flaperon half is driven by its own flight control linkage, not shown here.)
One of the 8 hinges on each flaperon half also serves as a retainer that handles side loads. (3rd and 4th photos.)
The flaperon halves are intentionally not very stiff longitudinally so that they flex with the wing, but they are much stiffer radially to resist deformation because they are driven at only one point by the flight control linkage. This feature is fairly easy to achieve in composite fabrication because you can orient the fabric fibers in certain directions. In this case we used Kevlar, not carbon or fiberglass.)

Assembling parts of the glider flight control linkages in tight places.
1st photo - if only every job were this simple! Room to get both hands in, visibility, room to turn wrenches, etc. That's more the exception than the rule.
2nd photo - looking into the landing gear box through a hole that's large enough for one arm/hand. At the far end, where the bulkhead walls and fuselage converge into a tight corner...and where there are plenty of parts already installed...I need to connect another push-pull tube. I can only get one hand in there, there is barely enough room to insert the bolt, I'm working only by feel, and I also need to start the nut and tighten it.
What to do?
3rd - bolt the rod end outside the landing gear box, insert through a hole, then spin the rod end into its threaded socket.
4th - there is only room for a half wrench to tighten the jamb nut.
Whew!

Collision detected!
Now that most of the glider's flight control linkages have been bolted, I'm starting to check for conflicts, rubbing, bumping, etc. Some places have multiple moving parts in very cramped quarters, or moving parts that come very close to stationary parts such as bulkheads..
This video shows one collision. (It's in the 'mixer' section of the flight control linkages, in the fuselage just behind the landing gear.)
Fortunately, this one is easy to fix...swap the bolt and nut on one part.
There is much more checking to be done throughout the glider....

I need to install some anchor plates into the glider, around a blind corner (a bulkhead flange) in cramped quarters.
https://www.aircraftspruce.com/catalog/hapages/anchornutsk1000.php
It's easy to drop these small parts, and Murphys Law dictates that they fall into an inaccessible place.
Fortunately, you can run string through the mounting lugs to serve as a lanyard.
If you install an anchor nut on metal, you use rivets. On composite panels you often embed them in epoxy.
If you work in a wood shop, you probably use tee nuts:

How fast does brake fluid dissolve certain tubing?
I have read that DOT 3 brake fluid will dissolve vinyl tubing, so I won't use it in my brake system.
But how fast does vinyl tubing dissolve in DOT 3? A couple days ago I put a piece of vinyl tubing in brake fluid. I also put a piece of Tygon tubing in fluid...as a control/comparison.
So far the vinyl has not turned into a pile of goo. Perhaps it's gotten a bit softer, but only a bit.
I'll run this experiment a bit longer, but not as long as the famous Pitch Drop Experiment:

The glider now has 12 pounds of lead shot and epoxy added to dead space in the very end of the tail boom.
My initial estimate of volume indicated that I could add 8 - 10 pounds this way. I'm pleasantly surprised, and I didn't make a chocolate covered mess of things as I was pouring this goop into the tail.
I need to add a few more pounds to the tail. Phase two of this project will use lead plate, bolted to the vertical fin spar. (I need to unroll the 1/4-inch plate first, then develop a template to cut the lead.)
I could not add the epoxy/lead shot mix all at once because of the exothermic reaction of epoxy. When mixed epoxy is in a thick blob (instead of a thin layer), it generates enough heat to warm itself...which accelerates the chemical reaction...releasing more heat...further accelerating the reaction.... I have seen epoxy smoking hot because of this, so I added a bit, waited a half hour, checked temperature with an IR non-contact thermometer, added a bit more when it was clear that the exotherm was only very mild, etc. That took a while, but turned out well.
I note that Roto Metals has a discount on some 1-inch lead plate. Get your fork lift ready. No free shipping!
