FIELD: engines and pumps.
SUBSTANCE: reflector of a turbojet engine combustion chamber bottom is made in the form of a plate that contains a hole. The plate is a section of a conical surface formed by rotation around the cone axis. The plate has one substantially concave side and one substantially convex side, and also a contour that comprises four sides. Two first sides of the specified four sides are arcs of concentric circumferences with the centre at the specified axis of the cone, and two second sides are segments of generatrices of the specified cone, which connect the first sides. The reflector comprises a central zone, which covers the hole, and a peripheral area, which covers the central zone. The central zone comprises a flat side near a substantially convex side.
EFFECT: arrangement of a heat protective screen or a reflector for the combustion chamber bottom, where the distances between the chamber bottom and this reflector remain same.
