Abstract:
A multi-channel combustion device including at least one radially partitioned inlet zone within an inlet port, and a plurality of circumferentially spaced chambers (12) in which deflagration or detonative combustion occurs. The inlet port may have a plurality of separate, circumferentially partitioned inlet zones (116) for supplying fuel and air mixtures to the inlet end of the combustion chambers. The inlet of at least one of the combustion chambers is radially partitioned to permit radial stratification within the combustion chamber. The device may be a combustion wave rotor (18) or a valved combustor (82).

Abstract:
Der gewohnte Bauplan der Gasturbine wird von innen nach auZen gekehrt: Brennraum und Luftstrahl rücken ins Zentrum des Triebwerks, die Funktion der ehemals zentralen Welle wird von der Triebwerkswand übernommen. Der Brennraum wird damit zur Zentrifuge. Flammgase werden durch Fliehkraft von den W.nden weg ins Zentrum der Brennkammer gedrückt. Querschnitt von Brennraum und Luftstrahl sind fortan kreisrund statt ringfbrmig.
Abstract:
The present disclosure generally relates to rotary turbomachinery methods and integrated processes requiring high-energy efficiency. In one embodiment, the present invention relates to rim-rotor configurations enabling long-term survival under conditions of either high temperature or oxidation resistance or saturated fluid abrasion.
Abstract:
This invention consists of a combustion chamber or chambers (1), which around an axis (4) and exhaust/s tangentially (3) to its/their circle of rotation within a jet engine (2). The combustion chamber/s may be fitted in an otherwise conventional turbojet, turbofan or gas turbine engine and linked to drive the air compressors and/or other devices. The combustion chamber/s (1) may be integrated with supersonic speed ram charging air scoops, which feed inlet air into the combustion chamber/s, forming (a) revolving ramjet(s). In this form, there may or may not be prior air compressor stages.
Abstract:
An orbiting combustor nozzle (OCN) engine, having a rotating assembly comprising a co-rotating compressor and nozzle wheel enclosed within a non-rotating outer casing, defining a rotating combustion chamber, is disclosed. Combustion occurs in the combustion chamber in a vortex of gas that rotates at the same angular velocity as the rotating assembly. Also disclosed, is a method of cooling a blade of a rotating wheel, such as a turbine wheel or nozzle wheel, by projecting cool air at the base of the vane from a nozzle corotating with the blade. Such cooling is easily implemented in an OCN engine with use of an innovative annular combustor. Also disclosed is a method of countering axial backflow by use of a combustion chamber compressor.
