Speaking of circular sliderules and wind triangles, do you think there may be interest in a video about the venerable E-6B flight computer? I still have mine, although I usually use an electronic version. It's fun to play with the aluminum whiz wheel every now and again.
I have to admit, at first I started to skip ahead thinking it was too technical, but then I went back and watched it again and I have to say, your presentation and explanations are top-notch and I really appreciate this channel! Very interesting stuff I would never have otherwise known about. Did you build the mount for the gyroscopic one or was it made for presentations?
I love stuff like this, learned to fly with an E6B analog computer. Giles, it may be unobtanium, but I'd like to see you talk about the navigational instruments used on spacecraft, particularly the Apollo instruments and the star sensors used on the Space Shuttle.
Very nice! Free teaching tips: Never confuse the focus and expectations of an audience by saying "we will cover this later" or similar. Just do it later. Eliminate the words "What" unless you are asking a question, and "How" and you will be forced to be direct and avoid all the "what that does is it..." and "how it works is it..." and the more egregious "What you wanna do now is you wanna" and all the related ridiculous filler phrases so common in UA-cam videos.
Hi Gilles, when you say at 12:32 that you simply divide the hight with the time to get the speed, what unit do you get that in? In fact the slide rule on Mark II does the division, and applies the factor for mph or knots, similar to E6B that the navigator would have anyway.
The result is in knots. Indeed, the "C" correction factors for measuring groundspeed in MPH with the B3 differ from the "K" factors by ~1.1508 - the conversion factor between knots and MPH.
Read a book years back, they would use in the Catalina, drop a flare, look at angular change over so many seconds, then 90 degree turn do it again. A little math and off you go
So do commercial airlines solely rely on GPS now? Or do they have modernized versions of these navigation devices in all planes "just in case" or as confirmation.
They use Flight Management Systems (FMS), which combine GPS with Inertial Navigation Systems (INS, which use gyroscopes and accelerometers to track the aircraft's movement) and radio navigation.
Is it specified that it's 110 volts as opposed to 120 volts? I find it fascinating that throughout history the "main power grid" is assumed to be either 110, 115, or 120 volts depending on the manufacturers of equipment. Where I live, the power grid fluctuates between 117 and 121 volts throughout the day.
Alec from Technology Connections did a whole video on this topic-as I recall, it comes from applying a fluctuation factor to printed specifications for electronics, such that while 120 is the target voltage, your devices can still work with a dip to 110V, and sometimes 117V will be stated since it's in the middle of the acceptance bracket of 110-125.
The gyroscopic effect doesn't really require a specific rotor speed, as long as the rotor is spinning fast enough that the forces generated by the gyroscopic effect exceed any friction in the gimbals. Of course this really only rewords your question to "how long do you have to wait until you're sure the rotor is going fast enough?"
Great video, but what do you do over the sea? Find a couple of seagulls being naughty ? Would it work with the old 1960s RAF Lightening, (which made the new US F35 look like a shopping trolley) at say 200 ft ? Got to have a laugh while the world goes to poo.
Firstly: Corps, not Core. Secondly, it stopped being the USAAC in 1941, and since the video covers a period from the 1930s until the 1950s, the least confusing single term to use is USAAF.
isnt it amazing that one can now do the same thing in a few minutes with an arduino nano and an IMU and code written by chatGPT. what a world we live in now!
This is rapidly becoming one of my favorite channels. Very interesting objects and a top notch presentation.
I heard "Erection" and being as immature as I am, made a joke in my mind only to hear "Giggity" a moment later and that got to me.
Looking dapper my man! As always, your content is both interesting and informative! And a “giggity” back at you!
Giggity!

i recall a saying "do you get my drift".maybe it came from this somehow.
Use of drift is very appropriate for describing the situation.
A little information allows understanding of a larger idea, if you get my drift.🙂
One of the best channels UA-cam ever suggest.

Fantastic explanation and delivery, as ever
Nice, I've often been curious about these older ariel navigation/military equipment when I come across them.

It's always fun when you're in the middle of watching a video and it suddenly becomes unavailable :) Then a few minutes later, version 2 is uploaded.
Navigation is an amazing topic be it land or air, always interesting!

Hello again, again.
So simple!
The Zeppelin, Hindenburg, was equipped with the German version of this.
7:51 See? Got to have a pupper to guide the way.
Love the intro
Enjoyed this, thank you.
Read a book years back, they would use in the Catalina, drop a flare, look at angular change over so many seconds, then 90 degree turn do it again. A little math and off you go
Thank you very much 👏
Thank you.
I'm not sure why I watched this, but it was interesting. :)
great video
The only thing I don’t understand is, where do you stack the nets after you put the fish in the hold?
Excellent subject and presentation. Curious how this would have been used over water.

7:50 "So simple, even a spaniel can use it."
is this where the phrase "i get your drift " comes from?
Second chance at being first xD Love you work
Giggity
I noticed a radioactive label on the b3 sight, I was wondering where the radium source is.
I was in the middle of watching it and all of a sudden it disappeared. Was very disappointed!
Sorry about that. I didn't notice the bad edit at the end and had to quickly fix it.
I was so confused by the inventor being called "Daddy." Am I hearing that right? lol

9:56 does anyone know how long the gyro took to spin up ? On older ships they can take an hour
The manual instructs you to hold down the startup button for one minute.
The gyroscopic effect doesn't really require a specific rotor speed, as long as the rotor is spinning fast enough that the forces generated by the gyroscopic effect exceed any friction in the gimbals.
Of course this really only rewords your question to "how long do you have to wait until you're sure the rotor is going fast enough?"
... a bit of a "tangent" indeed!

I'm interested to know what you fixed in the video edit
I accidentally left in two different takes of the outro.
@@CanadianMacGyver I see 👍
If it isn't broken then don't fix it. :)
Something so simple like a steel ball rolling around in this seems out of place... Someone came up with that $10 solution for million dollar problem
it is aemy air CORE, not air force

ok@@CanadianMacGyver
sorry i was wrong@@CanadianMacGyver
. . . and then . . . GPS
isnt it amazing that one can now do the same thing in a few minutes with an arduino nano and an IMU and code written by chatGPT. what a world we live in now!
It looks complicated, I don’t follow…aarrgghh
Giggity!
