Is of course possible and much more silent, needs ordinary motor for propeller.
Can be 3 on each wing to make same safety as jet. But they are not far after with 4 anyway.
Speed maybe 900km/h and 1000 for jet. The weight is not more, can be same. The watertank can be little smaller than for ordinary fuel. Hydrogen plus a little air is an effective fuel.
Sometimes one is reading about too much emissions from airtraffic, this is a good solution.
Of course I can make a very clean jet fuel, but is not worth the noise. The stress from noise shorten peoples life. 40 dB in propeller plane and 70 in the jets, why bother with the jet flight?
OK is possible to make a very silent jet. I better patent it.
01 0828 SAAB Sweden is making it. Test plane ready. Great surprise at Arlanda airport, Stockholm. A very silent jet plane. The King of Sweden has tried it. Saab have 6 pairs of silent jet motors and planning to put them on a passenger, and invite some professional birds to buy the idea. Its suitable for a Boeing A165. I can work out the dimensions for other airplanes.
Metal springs is more silent for car motors also. But if the motor is insulated from the rest of the vehicle, except for the fuel pipe then this pipe can crack if a lightning strikes. = Hindenburg accident, certainly happened like this, is now eleminated in new Zeppelins.
In future will be more Zeppelins, on hydrogen drive motors of course. Remember hydrogen is not stored in any quantities, it's made continuosly as needed for the motor, from water.
Zeppelins are 40% safer per passenger kilometer, Helium filled and 30 safer Hydrogen filled.
Including all accidentsa with it. Only 36 werre killed in the Hindenburg accident and not 100 as in Dagens Nyheter, at that time it happened. Now the cause for the fire is rather clear, and eliminated in the new Zeppelin NT. The pipe from the tank to the motor could not stand a lightning striking 20--30 min before the fire was discovered. Dripping burning fuel started the fire. A crack was found a few years ago in a crashed Zeppelin from Goodyear, in this pipe. I wrote them before it happened but they needed this accident.
