COOLING CHANNEL FOR THE COMBUSTION CHAMBER OF A LIQUID FUEL THREADED ENGINE

Abstract

The invention relates to a cooling channel for the combustion chamber wall of a liquid-fueled propulsion engine comprising: a hollow (100) tube of alloy with a square cross-section, the length of which is equal to the length of the combustion chamber; this tube (100) is attached directly to the inner surface of the combustion chamber wall by an underside (101) of the tube; on the inner surface (102) of the tube (100), on the same side as the underside (101), a number of identical reinforcing ribs (103) are arranged, each rib being in the form of a rectangular box, arranged parallel and perpendicular to the longitudinal direction of the hollow tube (100) on a length approximately in the middle of the hollow tube (100) and this section is at a distance from one end of the tube (100); The ribs (103) are shorter than the width of the inner surface of the hollow tube (100), and are arranged at equal intervals and in a staggered manner so that each rib (103) has one end in contact with a side edge of the hollow tube (100), and the other end is at a distance from the opposite side edge, with these gaps staggered.
