Abstract RU 2524785 C1

FIELD: engines and pumps.

SUBSTANCE: proposed device comprises poppet, augmenter tube, fastening assembly and support. Said support is shaped to truncated cone with conical part abutting over the end face on nozzle subsonic part at 80-100 degrees and flat part with OD making 0.2-0.3 of the support maximum diameter. Cylindrical sleeve with maximum OD making 0.6-0.8 of the support flat section OD is arranged between the support and fastening assembly at augmenter tube. Support conical part has 3-8 slits arranged in symmetry in length and width making 0.03-0.15 of the support maximum diameter.

EFFECT: decreased spread of in-ballistic parameters at starting operation.
