METHOD AND TLC FOR COOLING THE INTERNAL SURFACE OF A TRANSPORT AND LAUNCH CONTAINER (TLC) UNDER THE ACTION OF COMBUSTION PRODUCTS OF THE STARTING POWDER PRESSURE ACCUMULATOR (PPA) ON IT WITH THE MORTAR LAUNCH OF THE SOLID-FUEL ROCKET Russian patent published in 2018 - IPC F41F3/04 

FIELD: rocket equipment.

SUBSTANCE: group of inventions refers to the means of launching a solid-fuel rocket from a transport-launch container (TLC). In the method for cooling the TLC inner surface, under the action of the combustion products of the starting powder pressure accumulator (PPA) with the mortar launch of a solid-fuel rocket, into the cavity of the TPK, a low-temperature inert gas is blown into the TLC cavity from its bottom part along the inner surface over the TLC's perimeter with a flow rate proportional to the consumption of the combustion products of the PPA charge. TLC for a mortar launch of a solid-fuel rocket contains a casing in the form of a pipe with a bottom in which a launch PPA is installed. Bottom part of the TLC pipe is made in the form of an inner cup with a flange for external fastening to the TLC pipe. Outside the cup, around the perimeter, there are low-temperature (≤100 °C) pyrotechnic gas generators of inert gas, gas-bound with the internal cavity of the TLK through an annular receiver fixed to the outside of the flange of the cup, and holes evenly located in the flange of the cup.

EFFECT: reduction of the launcher evacuation timing after the launch of the rocket.
