EXPERIMENTELLE UNTERSUCHUNG DER FLAMMENSTRUKTUR FLIEGENDER EINZELTROPFEN FLUESSIGER UND GELFOERMIGER TREIBSTOFFE

摘要

FLAME STRUCTURE OF SINGLE FLYING GELLED AND LIQUID PROPELLANT DROPLETS - AN EXPERIMENTAL APPROACH Free moving and burning droplets of liquid and gelled mixtures of H_2O_2/Nitromethan and pure Nitromethan have been investigated. The combined use of highspeed cinematography, thermography and spectroscopy allows the determination of main reaction zones and in results in temperature distributions over the flying droplet. Gellants like aerosil change the burning behaviour of the droplets concerning stability and increased combustion temperatures.
