We have a present jet, and when it has taken off, we open the water valve. This allows water to be sucked through Venturi nozzles, to enter the jet exhaust as water drops.
These boil – and do Molecular Nuclear Fusion
A present jet engine does a little Molecular Nuclear Fusion, which is why we get an exhaust temperature of over 700oC. Rather than the 250oC we would expect from burning jet fuel. We also get the emission of X-rays, and producing of Helium: we are doing nuclear fusion.
We can increase the Molecular Nuclear Fusion, by running the engine at higher pressure – using Nimonic turbine blades. We should change to porous ceramic blades – which have sufficient strength. Cut we could them with TiO – a ceramic. That does Face Centred Cubic with steam molecules, and doubles the Molecular Nuclear Fusion we are doing.
The evidence from steam engine fire tubes, suggests that we get an exhaust jet temperature of 3,000oC. Rather than the 700oC we get today.This is going to push our jet along at Mach 5. Using standard runways! And as the jet is only operating for ¼ if the time on tick over, we are going to reduce the gas burn by a factor of 8.
