How to achieve a constant boom push at the fuel? A piston driven by circular motion will be sinusoidal...A jet engine! The fans provide the constant push speed. The fuel disintegrates.
How then to better utilize the various particles as the result of fuel disintegration? Conventional view of a jet engine only provides thrust, but all particles are present \((g^{+},\,g^{-})\) \((T^{+},\,T^{-})\) and \((p^{+},\,e^{-})\) as the fuel disintegrate. An average net accumulation of \(g^{+}\) particles in the jet provides lift, as smaller \(g^{-}\) particles are driven away quickly. What about the other types of particles? As \(g^{+}\) particles are driven into the open, it seems to be too wasteful. We are speculating that the jet engine provides lift by itself without Bernoulli principle being applied to an advancing wing driven by the engine's thrust.
Firstly, a jet engine working around a particular push speed, is best run with fuel of a narrow range of carbon number; a piston engine that provides a wide range of push speeds as the drive is in circular motion, is best run with fuel that has a wide range of carbon number.
Ignition point should not be a concern, at the correct boom speed. Ignition as the fuel nuclear disintegrate is guaranteed, theoretically. Ignition is wasteful as the fuel burns.
Should fuel be allowed to ignite at all? \(g^{+}\) particles provides lift and \(T^{+}\) particles provides thrust. Maybe...
