Summary:	Title screen An experimental study was conducted on the ignition and combustion characteristics of a hypergolic system consisting of tetramethylethylenediamine C6H16N2 (fuel), thickened with 5 wt% silicon dioxide SiO2, and highly concentrated nitric acid HNO3 (oxidizer) in a liquid state. In the experiments, gel fuel particles with a diameter of 2.5 mm were dropped from different heights (5 cm, 10 cm, 15 cm and 20 cm) onto a liquid oxidizer layer with a volume of 2 ml. Using high-speed video recording, the following characteristics were recorded: ignition delay times and burnout times of fuel components; the burnout area of the flammable vapor-gas mixture; the average velocity of fragments during a microexplosion. Flame temperatures were determined using high-speed two-color pyrometry. Also, using the Schlieren method, the characteristics were recorded: area and velocity of vapor propagation. Based on the experimental data obtained, a hypothesis was formulated regarding the ignition and combustion mechanism of hypergolic fuel system components (gel fuel particle and liquid oxidizer layer) Текстовый файл AM_Agreement
