A further object of this invention is to provide an improved rotary jet engine, the rotary jet engine being simple as possible in construction so as to be inexpensive to manufacture and at the same time being economical to operate due to its relatively great efficiency.

Referring now to the drawings, it will be seen that there are illustrated the features of the rotary jet engine which is. the subject of this invention, the rotary jet engine being referred to in general by the reference numeral 10. The rotary jet engine 10 includes the suitable stand which is referred to in general by the reference numeral 12. The stand 12 is formed of a base 14 which has extending upwardly at opposite ends thereof supports 16 and 18.
Extending through the supports 16 and 18 and fixedly secured thereto against rotation is a stationary hollow shaft 20. The shaft 20 is secured in place by means of a suitable clamp member 22 carried by at least the support 18. Rotatably journalled on the shaft 20 is a casing 24. The casing 24 is formed of a pair of identical halves 26 and 28 which have connecting flanges 30 secured together by means of suitable fasteners 32. The casing 24 includes a first reduced end portion 34 which is of a tubular construction and which is rotatably journalled on the shaft 20 by means of bearings 36. The casing 24 is also provided with a reduced end portion 38 remote from the end portion 34. The end portion 38 is also the tubular construction and is rotatably journalled on'the shaft 20 by means of a suitable bearing 40. Carried by the support 16 and engaging the end portion 34 is a bearing 42. A similar bearing 45 is carried by the support 18 and engages the end portion- 38. The bearings 42 and 44 serve to support the casing 24 for rotation. I
Disposed in opposite ends of the casing 24 are compressor units which are referred to in general by the reference numerals 44 and 46. The compressor units 44 and 46 are disposed in opposed relation and are otherwise identical. Accordingly, only the compressor unit 46 will be described in detail hereinafter.
The compressor unit 46 includes a plurality of fixed vanes 48 which are secured to the casing 24 for rotation therewith. The vanes 48 are of the reaction type, as is best shown in Figure 5. Rotatably journalled on the shaft 20 in alignment with the fixed vanes 48 is an impeller which is referred to in general by the reference numeral 50. The impeller 50 includesa hub 52 and vanes 54. The hub 52 carries suitablebearings 56 which rotatably mounts the impeller 50 on the shaft 20.
Referring now to Figure 4 in particular, it will be seen that there is illustrated a drive train 58 for driving the impeller 46. The drive train 58 includes an internal gear 59 which is secured to the hub 52. A second internal gear 60 is secured to the casing 24 in longitudinally offset relation with respect to the internal gear 59. It is to be noted that the internal gear 60 is 1 In order that the compressors 44 and 46 may operate, the casing 24 is provided with suitable air inlets 68 and 70, respectively. The air inlets 68 and 70 are formed in an ofiset portion of the casing 24 and feeds air into the reduced ends of the compressor units 44 and 46 Disposed intermediate the compressor units 44 and 46 is a combustion chamber 72. The combustion chamber 72 is larger than the adjacent portions of the casing 24 and that part of the casing defining the combustion chamber 72 is generally semi-circular in cross-section as at74. That portion of the casing 24 defining the combustion chamber 72 is provided with two rows of jet nozzles '76. As is best illustrated in Figures 1 and 6, the jet nozzles 76 are generally U-shaped in outline so as to cause the reverse direction of flow of gases passing therethrough. The gases exit from the nozzles 76 as at 78 in a line generally tangential to the periphery of the casing 24. Thus as the jet streams of the exhaust gases exit from the nozzles 76, the reaction force effects the rotation of the casing 24 in the opposite direction.
In order that combustion may take place in the combustion chamber 72, there extends through the left side of the shaft 20, as viewed in Figure 2, a fuel line 80. The fuel line 89 terminates at the inner end thereof suitable ejection nozzles 82, which are best illustrated in Figure 4. The fuel injected by the nozzles 82 is continuously combined with the air forced into the combustion chamber 72 by the compressor units 44 and 46.
In order that the combustion of the fuel-air mixture may take place, there are provided suitable electrode units 84 which are carried by the central part of the shaft 20 generally in vertical planes passing through the nozzles 82. Connected to the electrode units 84 is an electric wire 86 which extends out through the right hand end of the shaft 20, as viewed in Figure 2, and is connected to the necessary electrical supply source.
In order to effect the rapid movement of exhaust gases out through the jet nozzles 76 and thus increase the effectiveness of the rotary jet engine 10, there is provided a free spinning impeller which is referred to in general by the reference numeral 88. The impeller 88 includes a central hub 90 and a plurality of radiating vanes 92, as is best shown in Figures 2 and 6.
The hub 96 is rotatably journalled on the shaft 20 intermediate the fuel injection nozzles 82 and the electrode units 34 by means of a bearing assembly 94.
As is best shown in Figure 2, the vanes 92 increase in width from the hub 90 outwardly. The vanes 92 are also of a double U cross-section so as to provide two flow paths 96 and 98. The two flow paths 6 and 98 direct the exhaust gases towards the two rows of jet nozzles 76. Thus the flow of the exhaust gases from the combustion chamber 72 outwardly through the jet nozzles 76 is accelerated by the free spinning impeller 88. i
In order that power may be taken off of the rotary jet engine the reduced end portion of the casing 24 is provided with a drive gear 100. The drive gear 100 may be connected to any suitable power unit through suitable gearing (not shown).
From the foregoing description of the rotary jet engine 10, it will be readily apparent that it is of the extremely simple construction so that it will be inexpensive to manufacture. At the same time, because of the particular construction thereof, it will be economical to operate due to both the efiiciency of operation and the simplicity of the construction.
The foregoing is considered as illustrative only of the. principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention -to the exact construction and operation shown and described, and accordingly all suitable modifications and of the invention as claimed.
