Resumo:	Title screen An experimental study of the patterns and characteristics of ignition and combustion of hypergolic fuels with liquid components has been carried out. The experiments used tetramethylethylenediamine C6H16N2 (fuel) and highly concentrated nitric acid HNO3 (oxidizer). The initial volume of fuel and oxidizer droplets was 10 μl. The height of the fuel droplet fall relative to the oxidizer droplet varied from 5 to 20 cm. During the experimental studies, the following characteristics were determined: ignition delay times, burnout areas, and flame temperatures. The characteristics of the components interaction were also recorded using the Schlieren method. When varying the height of the fuel droplet fall, the ignition delay times change in the range of 42.4–54.9 s, the average values of the burnout areas change from 0.42 to 7.59 cm3. Moreover, the greater the height of the fuel droplet fall onto an oxidizer droplet on a plate, the shorter the ignition delay times and the larger the burnout areas Текстовый файл AM_TPU_network
