Further evidence that Colin Furze has a time machine.

Furze's pulsejet powered kettle gives an impression of the noise levels involved.
(Not safe for headphones).

That’s a lot of oil Derricks in the first photo…

Texas?

my understanding is the range of tip jet helicopters is pretty short, but what if you just want to take a friend to see the sights between local small airports?

They're also quite loud even compared to normal helicopters.

They don't have to be loud. The Sud-Ouest Djinn used a turbine to generate compressed air for the tip jets, and was quite quiet. It's also the only "cold" tip jet that was built in quantity.
The Jet Jeep was loud as fuck however, as it used the crudest and loudest of all types of jet engines. The pulsejet, the same type as used by the V-1 flying bomb.

The Djinn! When a design is successful: first the military buys it and then, commercial aviation equips them with agricultural spray bars. Winnah!

It's a neat craft considering it's objectively the only successful tip-rotor helo.

Depends on the scale. The Fairey Rotodyne

And could be heard at 900.
Moonbow_bow@reddit (OP)
Your friend needs his own, this thing seats 1
Delphius1@reddit
there's some multi seat tip jets out there, even a transit liner at one point, but that was cancelled because of noise
Moonbow_bow@reddit (OP)
There's also a ramjet version

I bet the bolts holding the tip jets on are on the pricey side.
Aleksandar_Pa@reddit
Dammit. I want one.

So fuel flows through the torture blades out to the jets. The rotors start spinning. As they accelerate, centripetal force pushes the fuel out toward the tips. Under pressure, more fuel flows out. So the rotors speed up even more. So fuel pressure increases. So the rotors speed up even more. Etc.
Am I missing something?
Delphius1@reddit
a master flow valve to control speed, but yeah, there would be a rubber band like throttle response
BrtFrkwr@reddit
I'll bet that was noisy as hell.
