DIRECT FLOW TURBORETACTIVE DETONATION ENGINE (DFTDE) Russian patent published in 2017 - IPC F02K7/02 F01D15/10 

FIELD: engines and pumps.

SUBSTANCE: direct flow turboreactive detonation engine consists of an inlet part, a middle part and an outlet part. The inlet part includes a fan and a compressor. The middle part includes a device for supplying fuel to the mixing section, a section for mixing fuel with air, a system for burning an inflammable mixture, and a combustion chamber. The output part includes a turbine and an outlet nozzle, as well as a fuel supply system, device for attachment to an external casing, and an engine management system. Inlet and outlet parts are made in the form of axisymmetric circular hollow rotating cones, interconnected through a narrow middle part by their narrow parts, having blades mounted on the inner surfaces of the cones that do not overlap the central part of the channel completely and forming spirals twisted around the common central axis of the channel. The inlet cone with blades serves as a fan/compressor, and the outlet cone with blades is a turbine and an outlet nozzle. The middle part and the outlet cone are combined into one integral part. The device for supplying fuel to the mixing section is made in the form of a centripetal pump. The burning system, by creating short high-voltage electrical impulses, provides combustion of the combustible mixture in the detonation mode. The rotating parts of the engine are attached to the outer casing via bearings fixed to the outer surfaces of the rotating parts.

EFFECT: providing an independent horizontal start and the possibility of changing, alternating speeds in the ranges from subsonic to hypersonic.
