Trigger warning: Exposed Fasteners

Is this typical for most aircraft? This is a Learjet C-21A, the other stratotanker I had seen in Topeka seems to have exposed screws as well, but Phillips head. I just find it interesting, I don’t actually mind the exposed fasteners. T he only planes I’m up close to are like these, on display stores outside. More later.

This and more are on display and open to the public in front of Scott Air Force Base in Shilo, IL just east of St. Louis.

In the older days they gave two shits about aerodynamics. Most jets I've seen that A. aren't passenger jets, B. are older than 2005-ish have exposed fastners.

I don’t have any real idea, but I would wager that it’s normal.

Dyess AFB up in Abilene (TX) has a fantastic air park. I used to play in the orchestra up there, and would visit during my time off. However, once that asshole flew planes into our buildings, they put it behind the gate and only people with military ID can get to it. This is just a small part of it.

Yes. Thousands and thousands of them... Rivets, high-torques, Hi-locs, barrel fasteners, cam locks, Dzus, you name it- it’s exposed.

Yup, especially on panels that need to be removed frequently. Incidentally , they’re not actually screws, but Dzus fasteners :

These fasteners are notable in that they are of an “over-centre” design, requiring positive sustained torque to unfasten. Thus, any minor disturbance to the fastener (e.g. vibration) will tend to correct itself rather than proceed to further loosening as it would in threaded fasteners.

Depending on the era of the plane, skin panels that aren’t expected to be removed regularly are riveted.

I’m not sure I can define what's  “typical for most aircraft” but I’ve seen it plenty on the planes I’ve been around, which is restricted to old military craft and civilian aircraft.

This is the wing and fuselage of a Piper PA-28-161. Screws hold on the wingtip and where there aren’t screws, there are rivets.

I wish my car was mad e like that. It would be so much easier to replace rusty panels.

When Viktor Belenko landed his MiG-25 in Japan, American engineers were horrified to find the plane was assembled with hand welding and round-head rivets. Granted, it was in areas either already disturbed or that wouldn’t face drag, but still, finding out that the Soviet super-fighter actually   wasn’t shocked some people.

I go to Oshkosh every year and look at thousands of airplanes.  Maybe there’s a few that *don’t* have exposed fasteners, but I can’t name one.  Probably a few composite airplanes don’t maybe.

The phrase has been applied to many air craft over the years, but the Avro Shackleton was famously referred to as “100,000 rivets flying in close formation”.

My favorite description of an aircraft is the one written by Roald Dahl ( Charlie and the Chocolate Factory ), who flew Hurricanes in WWII. He had this to say a bout the Gloster Gladiator :

Those old Gladiators aren’t made of stressed steel like a Hurricane or a Spit. They have taut canvas wings, covered with magnificently inflammable dope, and underneath there are hundreds of small thin sticks, the kind you put under the logs for kindling, only these are drier and thinner. If a clever man said, ‘I am going to build a big thing that will burn better and quicker than anything else in the world,’ and if he applied himself diligently to his task, he would probably finish up by building something very like a Gladiator.

Are Dzus fasteners used on dzebras?

Move to someplace where cars don’t rust. Simple.

Hulbert Field has an excellent airpark

porn alert!

So the notched bottom of the “screw” grabs a secured wire in place on the part to attach to. Cam locked in place. Over center than the spring adds tension to keep it in place.
