Abstract
Abstract A rotary internal combustion engine is shown having a combination of reaction nozzle means and turbine elements to extract energy from a stream of hot gases. A centrifugal air compressor feeds a rotary diffusion combustion chamber to operate the reaction nozzles. The products of combustion issuing from the nozzles are redirected by stationary vanes to drive a turbine to extract further energy from the gas flow as it passes to the exhaust.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
285 words
A rotary internal combustion reaction engine having air inlet, fuel injection means and an exhaust outlet for the products of combustion produced in the engine comprising a rotating air compressing means for receiving air from said inlet, said compressing means having a passage extending around at least 360° in the direction of its rotation, a rotating combustion chamber integral with and concentrically disposed with respect to said compressing means, said combustion chamber having an infeed throat at its inner end to receive compressed air from said compressor, said combustion chamber extending outwardly, from said throat, fuel injection means at said throat to feed fuel into the combustion chamber, igniter means at said throat to initiate combustion of the fuel and air at said throat, a common wall means for defining a portion of said compressing means and said combustion chamber to provide for a heat exchange between the infeeding compressed air and heat from the combustion chamber, reaction nozzle means near the outer end of the combustion chamber and rotating therewith forming an exhaust means for allowing the products of combustion to issue from the combustion chamber whereby to drive said compressing and combustion chamber means to rotate about a common axis, fixed frame means for supporting said air compressing and combustion means, fixed deflector blades carried on said frame concentrically with respect to said axis and said reaction nozzle means to redirect the flow of exhaust gases issuing from said nozzle means, turbine means disposed concentrically outside of said deflector blades to be driven by the exhaust gas flowing from said combustion chamber, and rotating driven means operatively connected to said reaction nozzle means and said turbine means to deliver power from the engine.
Claim 2
Dependent Claim
285 words
A rotary internal combustion reaction engine having air inlet, fuel injection means and an exhaust outlet for the products of combustion produced in the engine comprising a rotating air compressing means for receiving air from said inlet, said compressing means having a passage extending around at least 360° in the direction of its rotation, a rotating combustion chamber integral with and concentrically disposed with respect to said compressing means, said combustion chamber having an infeed throat at its inner end to receive compressed air from said compressor, said combustion chamber extending outwardly, from said throat, fuel injection means at said throat to feed fuel into the combustion chamber, igniter means at said throat to initiate combustion of the fuel and air at said throat, a common wall means for defining a portion of said compressing means and said combustion chamber to provide for a heat exchange between the infeeding compressed air and heat from the combustion chamber, reaction nozzle means near the outer end of the combustion chamber and rotating therewith forming an exhaust means for allowing the products of combustion to issue from the combustion chamber whereby to drive said compressing and combustion chamber means to rotate about a common axis, fixed frame means for supporting said air compressing and combustion means, fixed deflector blades carried on said frame concentrically with respect to said axis and said reaction nozzle means to redirect the flow of exhaust gases issuing from said nozzle means, turbine means disposed concentrically outside of said deflector blades to be driven by the exhaust gas flowing from said combustion chamber, and rotating driven means operatively connected to said reaction nozzle means and said turbine means to deliver power from the engine.
Claim 3
Dependent Claim
27 words

Claim 4
Dependent Claim
14 words
An engine as in claim 2 wherein the combustion chamber is an elongated passage.
Claim 5
Dependent Claim
29 words
An engine as in claim 2 wherein the flow of exhaust gases issues from the nozzle means in a direction at right angles to a radius through said axis.
Claim 6
Dependent Claim
26 words
An engine as in claim 4 wherein said combustion chamber has a closed outer wall forming a periphery and said nozzle means extend through said periphery.
Claim 7
Dependent Claim

Claim 8
Dependent Claim
62 words
An engine as in claim 6 wherein said frame includes a stationary frame means extending at right angles to said common axis and said compressor and combustion chamber are confined between a pair of rotating spaced apart walls each disposed at right angles to said common axis, and said rotating walls define opposite side walls of said comopressor and combustion chamber means.
Claim 9
Dependent Claim
35 words
An engine as in claim 7 wherein said engine includes a rotating drive shaft, bearing means on said frame means for rotatably supporting said shaft, and said rotating walls being fixedly supported on said shaft.
Claim 10
Dependent Claim
59 words
An engine as in claim 8 wherein the inlet includes a rotating mouth element forming bell shaped passage, fan shaped spokes for integrally supporting said mouth element on said shaft, an entrance from said passage into said inlet to the compressor means, and spirally shaped deflector blades surrounding said entrance to compress and deliver infeed air into the compressor.
Claim 11
Dependent Claim
30 words
An engine as in claim 2 wherein said compressor includes a widened entrance portion to said spiral path and the combustion chamber has a narrowed path at the throat thereof.
Claim 12
Dependent Claim
25 words
An engine as in claim 10 wherein the portion of said path forming the combustion chamber expands between said narrowed throat and said nozzle means.
Claim 13
Dependent Claim
