Patent Abstract:
The filed application is a supplement to my U.S. application Ser. No. 10/757,596 and to my German application No.: 103 02 041.1-13, which represent a basic conception for a novel internal combustion engine with the name: Injector-Centrifuge-Turbine-Engine (ICT-Engine) for road vehicles, and injector-Centrifuge-Jet-Engine (ICJ-Engine) for aircraft. New is the introduction of a supersonic injector in place of the turbine and the rotary compressor, and the introduction of a gas-centrifuge for decomposing of the mixed gases. In particular for aircraft, our presently used turbine-engines suffer from fatal turbine-blades crackings, which often results in aircraft crashes, with hundreds of burnt people. This can be eliminated by the novel engine. But also the automobilists would have a profit, by ca. 30% reduction in fuel consumption, arising from removal of the engine cooling and engine friction. The herewith filed application improves an essential component of the above mentioned novel engine, which is the Combi-Supersonic-Adjusting-Plug-Nozzle, fixing for it the following aims: 1) focusing of the jet stream; 2) increasing of the suction effect; 3) improvement of the design; 4) addition of a four-dimensional (4-D) vectoring; 5) suppression of the engine sound. Also the conventional plug-nozzle will be improved in the same manner, making it compatible with the novel injector-Centrifuge-Turbine/Jet-Engine.

Full Description:
[0001]     The invention relates to the novel internal combustion engine with the name: Injector-Centrifuge-Turbine-Engine (ICT-Engine) for road vehicles, and Injector-Centrifuge-Jet-Engine (ICJ-Engine) for aircraft, in accordance with my foregoing application for an U.S. Pat. Ser. No. 10/757,596, and my foregoing application for a German patent No.: 103 02 041.1-13, which are representing the basis conception of the engine. 
     
    
       [0002]     Brand new is the introduction of a gas-dynamic linear-compressor in the shape of a supersonic injector, which replaces the turbine and the rotary compressor. Added is also a gas-centrifuge, which decomposes the gases mixed in the injector, and which reduces the CO 2 — content.  
         [0003]     In particular for aircraft, our presently used turbo-aero-engines suffer from fatal fatigue-crackings of the high-heated and-loaded turbine blades. When a blade cracks, it destroys the interior of the engine, and the aircraft often crashes, with hundreds of burnt to death people. This can be eliminated by the new Injector-Centrifuge-Jet-Engine, which neither has turbine blades nor compressor blades in the engine main tract.  
         [0004]     But also the automobilists would have a profit, by ca. 30% reduction in fuel consumption, arising from removal of the engine cooling and engine friction.  
         [0005]     Whereas the application in hand improves an essential component of the above mentioned basic conception engine: the COMBI-SUPER-SONIC-ADJUSTING-NOZZLE, which will be further developed by additional inventive means. This application has a Prior Foreign Application in Germany No.: 10 2005 015 585.5-13, Day: Apr. 5, 2005.  
         [0006]     The combi-supersonic-adjusting-nozzle of said basic conception engine consists of a plug-nozzle and a Laval-nozzle, coaxially arranged in the nozzle plug. The ring-throat of the plug-nozzle is formed between the gas-jet discharge orifice  140  of the combustion chamber  2  and the central plug  182  of the nozzle, with the flow-direction through the ring throat conically from outside to inside, and flow direction through the Laval-nozzle straight on. The central plug consists of an inflow-funnel, a behind it positioned adjusting slider collet  4 , and the through both these parts leading Laval-nozzle. The adjusting slider collet has radial supporting stays  152  which star-like are pointing to the outside, up to an operation ring positioned round about of the nozzle, and which keeps the central-plug in position; at which the radial inner portions of the stays are lying in the hot supersonic region of the jet, whereas the radial outer portions of the stays and the operation ring already are lying in the cold region of the inducted fresh-air flow. To the operation ring is attached the mechanical operation apparatus of the nozzle.  
         [0007]     The whole above described aggregate is forward and rearward movable designed, in order to change geometrically the ring throat of the nozzle, and vary the gas flow area through the nozzle.  
         [0008]     (An information drawing of said basic conception, the Injector-Centrifuge-Jet-Engine, application Ser. No. 10/757,596, is enclosed as the last sheet of the drawings—FIG. X—, on which is supported this application).  
         [0009]     Starting from the above described Combi-Supersonic-Adjusting-Nozzle of the basic conception engine, it is the object of the present invention to provide an improved COMBI-SUPERSONIC-ADJUSTING-NOZZLE resulting in an increased efficiency and output capacity for all derivatives of the novel internal combustion engine.  
         [0010]     This object will be achieved by a closely cooperating package of inventive means, specified further below, for which will be fixed the following aims: 
    1) focusing of the jet-stream, in order to get a higher compression;     2) increasing of the sucktion effect, in order to get an increased mass-flow through the engine;     3) design-improvement of the nozzle-operation apparatus;     4) design-extension of the Combi-Supersonic-Adjusting-Nozzle to a four-dimensional (4-D) vectoring thrust-nozzle, in order to get an engine influencing the aircraft-maneuverability;     5) suppression of the sound radiated from the engine, in order to get a more smooth running engine. 
 
 Also the conventional plug-nozzle will be further developed and improved by the same package of inventive means, fixing for it also the same aims as described above, to make the conventional plug-nozzle also compatible with the novel Injector-Centrifuge-Jet/Turbine-Engines.

       DESCRIPTION OF THE PREFERRED EMBODIMENTS  
       [0104]     PHYSICAL CRITERION: A supersonically flowing gas stream can on a curved wall only so long be continually turned round, as long as the flowing gas is expanding.-When however the expansion is finished, a supersonically flowing gas stream can solely by oblique shockwaves be sharp edged deflected. On this criterion are founded the hereinafter submitted inventive means of the present application.  
         [0105]     The Combi-Supersonic-Adjusting-Nozzle of  FIG. 1 ;  FIG. 2  respectively  FIG. 11  and  FIG. 12  proceeds from the combi-supersonic-plug-nozzle of my novel Injector-Centrifuge-Turbine/Jet-Engine (application Ser. No. 10/757,596), and according to the present invention will be combined with:  
         [0106]     a supersonic-flow guide-shell  145 , a supersonic-flow guide-ring  146 , and several small supersonic auxiliary nozzles  148 . The s.f-guide-shell* has preferred a round cross-section, surrounds the adjusting slider-collet  4 / 69  of the central nozzle-plug  182 , is at the stream entrance on the inside strongly divergent, after an inside coaxial wall-inclination cylindrical or slightly divergent, divergence angle ε, and has at the stream exit a turbulence intensifier  150  in the shape of a rising corrugation, the corrugation grooves parallel to the flow. The function of the s.f. guide-shell  145  is the focusing of the jet stream. The s.f.guide-ring  146  also surrounds the adjusting slider collet  4 / 69  of the central nozzle plug  182 , has also preferred a round cross-section, is positioned inside of the s.f.guide-shell, and has in the longitudinal section the shape of a flat triangle: pointed at the leading edge, also pointed at the trailing edge, and blunt at the middle angle with a slightly rounding. The s.f. guide-ring is on its inside slightly divergent, divergence angle μ, on the leading autside edge also divergent, with a divergence angle nearly parellel to the arriving supersonic flow  143 , and it is at the trailing edge convergent, convergence angle δ. The function of the s.f.guide-ring  146  is to support the focusing of the jet-stream, by catching the supersonic gas jet-part  143 , which farther downward obliquely flows away from the adjusting slider collet  4 / 60 ; and both means: the s.f.guide-shell  145  and the s.f.guide-ring  146  are guiding more effective the jet into the nozzle-and engine main flow-direction.  *“s.f.-” means: supersonic flow    
         [0107]     The small supersonic auxiliary nozzles  148  are fastened to the ends of small supersonic gas-ducts  147 , which are star-like positioned round about on the outside of the s.f.guide-shell  145 . The small supersonic auxiliary nozzles  148  are behind their inside shockwaves increasing the cross-sections, to supersonically accelerate the flow, and are additionally sidewards widened, in order to correspond with the area rule of the gas dynamics, what reduces the shock-losses. Said nozzles have also spiral-angel  176 , augmenting the jet rotation. The function of the small supersonic nozzles  148  is to admit an initial suction-injector  149  in the shape of a ring-gap, round about the inventive nozzle, to intensify the suction effect. The same small supersonic auxiliary nozzles  148  are also adopted for the propelling nozzle  85  at the rear end of the engine, in order to suppress the engine sound radiated from the engine, by producing a slower jacket-flow round about the jet stream.  
         [0108]     Hereinafter will be disclosed more particularly the flow characteristics and the operation mode of the above described nozzle means. The gas-flow in the nozzle, prior to the installation of the inventive means, is identified thereby that,  FIG. 3 , after the gas has passed the ring throat of the nozzle, and is turned into the main flow direction of the nozzle, one portion of the flow  142  remains close upon the fillet wall of the adjusting slide-collet  182 , due to the gas mass-inertia at supersonic speed, what results in the pressure-course  142  on the slide-collet wall, as shown in  FIG. 4  resp.  FIG. 5 , whereas a second portion of the flow  143  more violent expands, and obliquelly flows outward. The outwardly flowing gas portion  143  forms himself an abrupt pressure drop, as shown in the cross-sectional profiles of  FIG. 5 . And from this pressure drop flows the gas outwardly with further increasing supersonic speed.  
         [0109]     This flow pattern is the virtual basis for shaping the package of the inventive means, because the outwardly flowing gas portion will be utilized, to boost the engine injector effect, and to increase the pressure in the engine.  
         [0110]     Additionally the outwardly flowing gas portion  143  expanses near of the gas discharge orifice  140  of the engine housing very suddenly and violently, and forms a narrow curved path  180  (like a toroidal vortex) with such a flowing speed that the gas-mass inertia—centrifugal forces produce in the center of said curved path  125  a pressure-free or depression zone (!).  
         [0111]     In the supersonic flow guide shell  145  the coaxial inside wall inclination, and the inner inclinations of the small auxiliary nozzles  148  are triggering oblique shockwaves  14   b . Also the leading edge of the super-sonic flow guide ring  146  trigers the shockwave  174   a . All these schockwaves together are guiding the flow into the nozzle main flow direction.  
         [0112]     Since the s.f. guide shell  145  and the s.f. guide ring  146  have internal converging wall-angles ε and μ, and the s.f. guide ring on the outside the diverging wall-angle δ, and additionally the auxiliary nozzles  148  have also diverging endparts, the flow repeatedly expands after the shockwaves, what results in an additional nozzle thrust  
         [0113]     The supersonic flow guide shell  145  and the supersonic flow guide ring  146  are by means of radially arranged supporting stays  152  fastened to the operation ring  60 / 87 , at which the middle portions of the stays, the s.f. guide ring  146 , and the s.f. guide shell  145  are lying in the hot supersonic flow of the nozzle, whereas the outer portions of the stays  152 , the small supersonic auxiliary nozzles  148  and the operation rings  60 / 87  are already lying in the cold subsonic air-flow.  
         [0114]     The whole above described aggregate is forward and rearward movable designed, by which the ring-throat of the nozzle is geometrically change-able, and the nozzle flow cross-section variable. For this purpose serves an operation apparatus  6 / 88 , consisting of at least three gear-spindles or at least three rack-and pinion gears, which is also lying in the cold sub-sonic air-flow, and which handles and moves the operation rings  60 / 87  with the nozzle aggregates.  
         [0115]     The inflow-funnels  5 / 70  are made of technical ceramics, and are detachable fastened to the adjusting slide-collets  4 / 69 . For this purpose are used screw bolts  155 , positioned parallel to the axis of the nozzle, and flow-conformal nuts  156 , as shown in  FIG. 9 ;  FIG. 10  and  FIG. 14 .  
         [0116]     The additional swivelling device for a four-dimensional (4-D) vectoring of the jet stream of the COMBI-SUFERSONIC-ADJUSTING-NOZZLE, according to  FIG. 11  and  FIG. 12 , is provided to make the jet-stream of the Injector-Centrifuge-Jet-Engine deflectable to all lateral directions  162 , in order to get an engine influencing the aircraft maneuverability.  
         [0117]     For this purpose the inner nozzle aggregate, consisting of the central plug  182 , with the inflow funnel  70  and adjusting slider collet  69 , supersonic flow guide-shell  145 , supersonic flow guide-ring  146 , and supporting stays  152 , is flexibly joined with the operation ring  87 . The specified aggregate is on its forward cold end connected with the operation ring  87  by means of at least three swivel arms  158  with spherical joint-ends; said swivel arms being arranged in the shape of a pyramid, with the pyramidal apex pointing against the flow direction. There is also provided a twist-preventing device with two swivelling arms  159 , of which each arm has on its one end a gearwheel-segment. Said gearwheel-segments are attached to the inward sides of the arms, and the two gear-wheel-segments are meshing with each other; this occuring in a small housing, which is also fastened to the forward cold end of the supersonic flow guide-shell  145 . The two swivelling arms  159  are so arranged that when one arm swings out like a clockwise rotation, the other arm swings out like an anticlockwise rotation, and vice versa. Said swivelling two arms  159  are on their outwardly pointing ends connected with compresion/tention struts  154  by means of spherical joints. The struts stand perpendicularly or near perpendicularly to the two said swivelling arms, and are at their other ends connected with the operation ring  87 , also by means of spherical joints.  
         [0118]     All these elements taken together form the vectoring nozzle aggregate which is able to be swiveled in all directions around the swivelling center  160 , without the pyramidal group of the swivel arms  158  would collapse. At which aggregate the small longitudinal oscillations of the swivelling center  160  will automatically be equalized by the operation apparatus  88 .  
         [0119]     In the ring-gap between the end-housing  151  of the jet engine and the supersonic flow guide-shell  145 , that is in the dividing slit between the immovible part and movible part of the vectoring nozzle, is no fire-proof gasket necessary! 
         [0120]     This is an extraordinary advantage of the presented jet-vectoring nozzle, because all other, and hitherto known vectoring nozzles imperatively require such fire-proof gaskets, which are expensive and very trouble-some in practical operation.-The inventive vectoring nozzle can dispense with said fire-proof gasket, originally utilizing the gas mass-inertia at supersonic flow.  
         [0121]     At the inventive nozzle-design the expanding hot gas-jet, which is discharged by the end-housing  151  of the jet-engine, triggers shortly after the ring throat a narrow curved path  180 , which due to the high speed and the mentioned gas mass-inertia produces in the center of said curved path a pressure-free or depression zone, as already specified in connection with  FIG. 3 ;  FIG. 4 , and  FIG. 5 . Now, said pressure-free zone will be intentionally placed between the mentioned immovable part and movable part of the nozzle, by which between the two said parts do not exist any outwardly urging pressure potential, and thus no fire-proof gasket is required! In addition, the ring throat of the nozzle is located on a spherical surface with the radius “R”, which enables movements of the vectoring nozzle aggregate to all side directions;-on the contrary to presently known other vectoring nozzles, which are variable only within one plane.  
         [0122]     For operation of the above specified Combi-Supersonic-Adjusting-Nozzle as a (4-D) vectoring nozzle, is provided an electro-hydraulic operation regime, working according to the “Fly-by-Wire”-principle.  
         [0123]     The hydraulic actuating cylinders  161  are on one side connected with the supersonic flow guide-shell  145 , and on the other side with the end-housing  151  of the jet engine. There are at least 4 actuating hydraulic cylinders, which are provided in two pairs of two cylinders, in each case on two planes going through the longitudinal axis of the nozzle. These planes are standing perpendicularly to each other. One pair of cylinders for swivelling the nozzle to the left and right side, and the second pair of cylinders for swivelling the nozzle upwards and downwards. Said cylinders are bilaterally effective. In each of said planes the hydraulic lines of the cylinders are crosswise connected  184 , so that one piston side of one cylinder is connected with the other piston side of the other cylinder  FIG. 13 . By said crosswise connection cooperate the two mentioned cylinders in this way that one piston rod has push-forces, and the other piston-rod pull-forces, or vice versa. This crosswise line-connections of the cylinders have the advantage that the lateral swivelling movements of the vectoring nozzle aggregate are independent of the linear adjustements of the thrust nozzle, accomplished by the operation apparatus  88 .  
         [0124]     To complete the Combi-Supersonic-Adjusting-Nozzle, also the conventional plug nozzle has to be taken into consideration, making it compatible with the new Injector-Centrifuge-Turbine/Jet-Engine, by applying the same inventive package of means, as specified above.  
         [0125]     The conventional plug nozzle consists of: a housing  181 , which is integral with the engine, and cylindrical or slightly divergent in shape, but which has at the stream entrance a constriction, after which the inside diameter conically alters into said cylindrical or slightly divergent shape. Furthermore comprises said conventional plug nozzle a central nozzle plug  182 , in the shape of a zeppelin, being round at the stream entrance and convergent at the stream exit. Between said entrance constriction of the housing and the entrance-rounding of said nozzle plug  182  is formed the nozzle-ring throat, with the flow direction through the throat conically from inside to outside, after which the flow is guided into the general axial flow direction of the nozzle, by said cylindrical or slightly divergent part of the housing  181 .  
         [0126]     This basic design of the conventional plug nozzle will now be improved by addition of the above specified package of inventive means, to make it compatible with the new Injector-Centrifuge-Turbine/Jet-Engine,  FIG. 14  and  FIG. 15 .  
         [0127]     The central nozzle plug get an axial Laval-nozzle, going straight through, from the stream entrance to the stream exit of the plug.  
         [0128]     The central plug will be devided in two parts, the forwardly positioned inflow funnel  70 , with the inflow opening  183  for the Laval-nozzle, and the rearwardly positioned adjusting slider-collet  69 . The Laval-nozzle is dimensioned for the idle-operation of the engine. The adjusting slider collet get radial supporting stays  152 , which star-like are pointing to the outside, where they are attached to an also added operation ring  87 , positioned round about of the nozzle, and which together keep the central plug in position. The outside contour of the adjusting slider collet  69  get at the starting points of said supporting stays, on both sides of each stay, local recessions  90 , in accordance with the area rule of the dynamics of compressible fluids.  
         [0129]     At this design the central plug and the radial inner portions of said stays are lying in the hot supersonic region of the jet, whereas the radial outer portions of the stays and the operation ring already are lying in the cold region of the inducted fresh air flow. To the operation ring  87  is attached an also newly added mechanical operation apparatus for the nozzle. The whole above specified aggregate is forwardly and rearwardly movable designed, in order to geometrically change the ring throat of the nozzle, and vary the gas flow area through the nozzle.  
         [0130]     The housing of the nozzle get, at the stream exit, a turbulence intensifier  150 , with the shape of a rising corrugation, the corrugation grooves-lying parallel to the flow.  
         [0131]     The additional small supersonic auxiliary nozzles  148  are fastened to the ends of small supersonic gas-ducts  147 , which are star-like positioned round about on the outside of the nozzle housing  181 . The small supersonic auxiliary nozzles  148  are of the same design as specified on sheet  10  of this description, and as shown in  FIG. 6 ;  FIG. 7 ; and  FIG. 8 . The auxiliary nozzles are behind their inside shockwaves increasing their cross-sections, to supersonically accelerating the flow, and are additionally widened sidewards, in order to correspond with the area rule of the gas dynamics, what reduces the shock losses. Said nozzles have also spiral-angle positions  176 , augmenting the jet rotation. The function of the small supersonic nozzles  148  is to admit an initial suction-injector  149  in the shape of a ring-gap, round about the inventive nozzle, to intensify the suction effect of the engine. The small supersonic auxiliary nozzles  148  are also adopted for the propelling nozzle  85  at the rear end of the engine, in order to suppress the engine sound radiated from the engine, by producing a slower jacket-flow round about the jet stream.  
         [0132]     The inflow funnels  5 / 70  are made of technical ceramics, and are detachable fastened to the adjusting slider collets  4 / 69 . For this purpose are used screw bolts  155 , positioned parallel to the axis of the nozzles, and flow-conformal nuts  156 , as schown in  FIG. 14 . The ceramic inflow funnels  5 / 70  should be made of a heat-conducting material, e.g. of SiC, by which the inflow funnels get the capacity to transport the absorbed heat to the rearwardly expanding gases, what thermodynamically increases the efficiency.  
         [0133]     All above specified Combi-Supersonic-Adjusting-Nozzles are also provided for Rocket-Engines.
