Drone Flight around a Tornado Siren (Federal Signal Thunderbolt)

[@rainyrec]

Jay Robinson: "How exactly does a T-Bolt work? Where is the blower? How is the noise transferred to the horn? " Q: How exactly does a Thunderbolt work? A: A Thunderbolt works using a chopper and blower with a rotator, all of those require motors. The Thunderbolt uses the air from the blower via tube, and amplifies the sound, the chopper spins and makes noise by chopping air and using the blowers air to make more noise. the rotator uses a motor and gear reducer to make it rotate specific RPM's (2,4, and 8 RPM) then that directs the sound. Q: Where is the blower? A: The blower is in the box at the lowest point of the pole or on a pallet with supports. Q: How is the noise transferred to the horn? A: The noise is right behind the horn where the chopper resides, it chops the air inside and blower air to make the noise that the horn directs. Hope this helps, 😊!

The Federal Signal Thunderbolt is actually one of the most innovative sirens ever built. The blower is that large rectangular box at the bottom of the siren. The blower is essentially an air compressor, and pushes air up that yellow pipe leading from the blower into the rotator box. The rotator rotates the siren head 360° during operation. The chopper motor is located inside the little cylinder on top of the rotator, and is powered via collector rings inside the rotator. The blower pipe leads to this location. When the chopper is spinning, instead of pulling air through an opening near the chopper naturally like a traditional mechanical, a Thunderbolt pressurizes air, and forces it through the chopper. This allows the Thunderbolt to have multiple chopper terminals (levels), because no matter how fast the chopper is spinning, the blower ensures that the same amount of air is getting pushed through, and that the dB output is the same. After the sound is produced, it’s pushed out the projector, which is that horn like object attached to the cylinder. That’s how a Thunderbolt works. Only one other blower supplied siren was mass produced, and it was the ACA Hurricane series. But no model of the Hurricane came with chopper terminals like the Thunderbolt did

the blower is the yellow box and the sound comes from a pole that leads to the stator making more air that goes through the horn projecting noise to make a t-bolt noise

That siren used to scare the living crap out of me every Wednesday afternoon at the playground close by

Blonde_BirdAv haha! Oh hey I’m shuttlesworth.spotter btw

@@jayrobinson8089 hold up, WHAT????

The “cylinder” behind the horn is where the chopper ad chopper motor is. That box under it is the box with the rotator components and rotator motor. The large box under the standpipe is the blower box.

If I got this close to a thunderbolt, I'd go OOOOOOOMAHFLLIIIPPINGERSCH and then explode

Good old ASC Radio XD

This looks like Richland Elementary, White Station is on the backside of this school.

[@blonde_birdav7685]

Looks like the siren‘s paint faded over the years since I last went there

[@friedmanirit]

What camera is mounted on the quadcopter. I would suggest to have better siren audio just in general for your videos where they go off. But overall great videos and nice job so far!

[@BrandonLe621]

Is a drone with a camera already on it

[@Tommy-pv1vh]

this one is a 3ph or A seres tbolt 1000/t

[@PlatinumEagleStudios]

WTF????? Is that a T Bolt running off an ASC radio?? LOL never seen that before

[@bnsfbandit9807]

Now you have LOL

[@1000BT]

its 5/6 and reverse wired and it doesnt rotate

[@CoolSirens1000T]

0:36 american signal corporation on a thunderbolt um????????????????????????????

[@OWS_Crazy1]

Does this work?

[@TheJakeman789]

it has ASC controller??

[@childishtombino1275]

Not a controller but a radio

[@CYang-pe1sk]

So an ASC-Thunderbolt

[@mws8025]

0:06 ASC Controls? ILLUMINATI CONFIRMED

[@zachj9359]

i saw that! Maybe its an ASC controller at the ema

[@theowlfan9050]

Whoa whoa whoa should be made by fs or cd

[@theowlfan9050]

nvm
