Thermal batteries typically contain a solid electrolyte consisting of a eutectic mixture of alkali metal chlorides which is made molten by a small pyrotechnic heat source. They can have a shelf life of twenty to thirty years or more. Typical output voltage is between 10 and 40 volts but some can produce several hundred volts.
@@fredmitchel1236 google "EAP-12359%200223.pdf" It's a strange spec; it's only spec'd in terms of current spikes at the given voltage, not continuous current if i understand it correctly; something like "12.3 A 100 ms pulse at 1.5 sec" A large current but only ON for 100ms with 1.5 sec resting time......
Thanks i they some how converted the heat from the explosion lol Like the lil electrical cooling pads (pelter modules ) or something excuse me self taught lol
I wonder how this compares to the konkurs. Specifically, the batteries used. I think this gyroscope is an improvement in terms of sheer size. The approach is interesting, thanks for sharing.
Professeur, veuillez expliquer à nouveau les pôles des deux batteries thermiques, suivis du missile, en détail, les dangers de la recharge et de l'activation, les tensions, la sortie😘😙😗✊👏👏
The compressed nitrogen is fed to the gyro using the pipe one can see at 06:16. At the beginning the gyro is orientated such that the rotor can rotate with the pressurized nitrogen fed to it. We can see at 06:25 the shaft of the rotor aligned with the hole. I think that at the beginning the shaft is linked to something inside the hole which rotates with the pressure. According to a document I found the gyro is liberated when the speed of 42000 rpm is achieved, after that the rotor continues to rotate freely during the flight of the missile.
A charge is required to activate the heat pellets inside the battery to ignitiate the battery. The heat produced is converted in electric power. A thermal battery is one time use.
Minimum charge required to fire the ignition squib. The heater charge is an aluminum silicide termite that melts the salt mixture inside. The cathode is generally made of a magnesium alloy, the anode is made of graphite combined with copper oxide or iron oxide.

and VERY expensive!
And say you had a 40 VDC thermal battery. So how much current can it put out at 40 VDC and for how long?

Oh the Eureka vacuum cleaner. I still have it running after a very long time. Thanks for the video.
Cool...I never thought I ever seen the inside of a TOW missle
Very cool!

Очень познавательно. Спасибо.
Merveilleux! Je pensais que les fusées filaires n'avaient pas besoin d'un gyroscope.
Au moins le roulis est stabilisé, je pense à cause de la liaison filaire.
Nice. Do you also have the steering motors for this? I'm curious what type of motors are used to steer the fins
Unfortunately I don’t have the rear assembly. The fins are driven using a bottle of compressed helium, some kind of electro-valves are used for that.

How does the compressed nitrogen spin the gyro?
I guess the nitrogen only has to get the rotor spinning for a short time rather then power it continuously
The compressed nitrogen is fed to the gyro using the pipe one can see at 06:16. At the beginning the gyro is orientated such that the rotor can rotate with the pressurized nitrogen fed to it. We can see at 06:25 the shaft of the rotor aligned with the hole. I think that at the beginning the shaft is linked to something inside the hole which rotates with the pressure.

@@lelabodemichel5162 lots of things happening quickly when they pull that trigger!
Isnt this classified? 😅
If there is a charge required to batteries, why aren't they called capacitors

perhaps only 5-15 seconds...@@lelabodemichel5162
@0:15 Do you not enjoy having sight? Where is your eye protection? Let me guess, no hearing protection either?
Aburrido. mejor consigue un himars y nuestra como los hacen los gringos.
