Use of additive mixtures as a means for increasing the vaporisation rate and combustion rate and also the combustion stability of liquid propellants and fuels injected into rocket combustion chambers or high-performance combustion installations

摘要

Additive mixtures which consist of a) organic compounds with highly conjugated pi -bond systems and longwave main absorption bands in the wavelength range from about 350 to 1200 nm, b) organic surface-active substances and c) organic solvents and suspending agents for the components a and b, are used as agents for increasing the vaporisation rates and combustion rates and also the combustion stabilities of liquid propellants or fuels and oxidisers for rocket engines or other high-performance combustion installations which are likewise operated with liquid fuels and in which there are combustion problems comparable to those in rocket engines and caused by disturbances in energy transfer. The additive mixtures are injected into the combustion chamber together with the propellants or fuels and the oxidisers with uniform distribution, which is as symmetrical as possible, in a geometrically optimum manner in accordance with defined economical methods. Owing to their property of exchanging radiation energy, highly conjugated pi -bond systems effect in combination with surface-active substances faster, more uniform activations of major fractions of molecules participating in the combustion up to the stage of the state ready for reaction, which is tantamount to enhanced stabilisation of the combustion process.
