FIELD: rocketry; ramjet engines. ^ SUBSTANCE: system to overlap hole of air intake designed for overlapping air intake into combustion chamber of ramjet engine has at least one obturator with glass plate made for complete overlapping of said hole in channel and at least one device to destruct glass plate of obturator. Obturator is provided with great number of protective elements made of elastomer secured, at least, on first side of glass plate which can be subjected to impacts. Said protective elements are arranged at preset maximum distance from each other and they completely overlap first side. Invention prevents untimely destruction of obturator if system overlapping air intake hole of ramjet engine before operating conditions are achieved. ^ EFFECT: improved reliability in operation. ^ 12 cl, 3 dwg |
