Payload V1 intended for Antwerp cleared

Several parts of a V1 flying bomb were blown up today in Lochem. The 935kg explosive is being detonated in parts of 50kg. The V1 was found last year during road works near Deventer. It was produced shortly before the end of the war.

The Germans did not have enough of the intended explosive materials for the bomb and used a mix of various other materials to fill the payload. Major Peters says they've found 'raketkruid'. The mix requires a set of smaller explosions to clear all of it.

I never heard of that term before. Google Translate says it is 'rocket herb' in English and 'Raketenkraut' in German. It sure does sound dangerous.

The payload was intended for the port of Antwerp. But after 20 kilometers or so, the V1 ditched into the clay. The bomb is charged in-flight after 6-8 minutes. But before that timer ran out, it was already on the ground. The mechanism which should ignite the bomb on impact therefore never activated.

So it's not a huge explosion..
edit: video is gone..

Not sure if this really fits, but later V1 warheads used a mixture called Trialen, where pellets or "biscuits" of Trialen-109 had been placed into a matrix with Trialen-105 poured around. This kind of production method had been called "Stuckfüllung" or biscuit filling in English.



This method made an otherwise shock sensitive explosive rather shock insensitive. Possible that the dutch term denotes this.

A big problem for Germany late in the war: The explosive mixture required lots of aluminum powder, which the country did not have.

“Tail in the water, head in the air,” Martin sang, confusing Marchenko. “Sorry—it’s a German children’s song.”

Reading that, is the quote true?

Not sure about the quote, but the song is correct. Its a part of "Alle meine Entchen", if you translate it into German, a childrens song about the typical behavior of ducks.

but the song is correct.

It's written the wrong way around though... The head should be in the water, the tail in the air.

Since the magnetometer was too close and I currently do not have access to stores or 3d printers due to the current ongoing unpleasantness I did what I had to do. :lol:

Now it has the same low CoG as a Vespa...

 

[Fabri91]

Yes, but what isn't seen is that in such multirotors the battery is often also installed on top of the frame.

And there's the good old rocket pendulum fallacy, too

It is no fallacy that rockets are inherently instable and need control to not cartwheel away. Putting the rocket engines on top just won't change that at all. :lol:



Contrary to aircraft and rotorcraft, which can be self-stabilizing.



But sometimes you want something instable to be able to rotate faster.



And putting the batteries on top on a Quadrotor should move the CoG closer to the rotor plane, which means, the stabilizing lever arm is shorter and the quadrotor not overcontrolled, which would make flying it much harder.

 

[Fabri91]

Luckily the control authority of such quadrotors is absolutely obscene and unless a significant load (such as the battery) is positioned so far out that it'll change the moment of inertia by a very large amount the controller software will deal with anything this side of an attack by an eagle.

Apparently, with arrival of the quarantine measures last weak, our central message broker has started to panick and is now hoarding threads. It's not healthy for it of course, and it's the third day of analysing what's going on, and I'm getting reeeeeeeally tired from looking at thousands of log entires and googling for obscure details that might yield a hint... :dry:

No problem, that find and egrep can't solve. Or ElasticSearch of course.

There's no data it can't find, but that doesn't solve your problem if you don't know the underlying technologies you're working with... :lol:

Ooooook... that sounds worse, if you are still at the stage of "Is that line a bug or a feature". (If you ask the software manufacturer, it is of course, always a feature and you are just using it wrong. :dry

Sounds more like the British version of the Mierscheid law in Germany.

Indeed!

I like a good graph, but I can't see any link myself.

That seems to be backwards. What the article says is not that lead pollution caused certain things, but rather that the rise and fall in lead pollution map precisely to known policies and circumstances. They don't say that the bishop was killed because the king was mad of lead poisoning, but rather that there is a significant spike in lead pollutuion following the murder, when Henry was building monasteries like mad to get back in favour with the pope.
I found it quite interesting really. Goes to show that mankind has been having quite an impact on the environment since way before force multipliers like steam or electricity.
