Definitions

• This invention relates to a propulsion apparatus for the propulsion of vehicles or power generators in air or in water in such a way that heat energy contained by the.fluid in which said apparatus operates, air or water, is utilised to perform propulsion work so that normally not any addition of external heat, like by burning of fuel, is required, except at a very high speed, supersonic, when said heat energy is insufficient, an external heat must be added.
• This invention relates to propulsion apparatuses which are propelled not by the reaction of issued jet of fluid, like in conventional jet propulsion systems, but by a force similar to the force which propels a balloon, without leaving a rearwardly directed jet of fluid behind the apparatus.
• Such force has the ability when it performs work like in case of a balloon, to convert heat directly into work without involving any of conventionally used thermal cyclic processes.
• this invention facilitates the utilisation of the heat contained in atmosphere or water to perform the propulsion work, thus facilitating the utilisation of the vast energy stored as heat in environmental fluids as an energy source.
• This propulsion apparatus consists mainly of a number of converging and diverging ducts.
• the ducts can be in any combination.
• the apparatus consists, pre erably, of two converging and one diverging ducts arranged so that the fluid enters the apparatus, which is in motion, through the wider end of a converging duct which is connected at its narrower end with the correspondingly narrower end of a diverging duct which is also connected at its wider end with the correspondingly wider end of the second converging duct.
• Propulsion produced by the work resulting from a thrust generated in such a combination of ducts is obtained from the heat provided by the fluid, from its own heat, in the diverging duct so that the fluid issues from the apparatus cooled by the amount of work resulting from the thrust.
• Fig. 1. and Fig. 2. illustrate and explain the concept of this invention and in particular:

• propulsion apparatus shown on Fig.3 and Fig.4.
• This apparatus is suitable for propulsion in water or in air at subsonic speed.
• Cross section can be of a circular, oval, rectangular or any other required form.
• the apparatus consists mainly of three ducts: converging inlet duct 1; diverging duct 2 and second converging duct 3. All ducts are connected to each other as is illustrated on Fig.3.
• a cowling 9 is provided which forms also the converging inlet duct 1.
• a conical structure 4 of which thin ends extend into inlet 7 and into outlet 8.
• This conical structure consists, preferably, of two parts which can be inserted into each other at their wider end in order to control the thrust.
• This control is effected by a hydraulic or pneumatic cylinder 10 which can move the desired conical end either into the inlet 7 or into the outlet 8. By this the fluid's flow area can be restricted or completely closed controlling by this the thrust.
• the part of conical structure 4 which is not movable is solidly connected to the duct by ribs 11.
• this apparatus can generate thrust only when it is in motion. Then the surrounding fluid is rammed and forced to enter the apparatus through .duct 1 and flowing fluid forms in the apparatus the effect described and illustraded on Fig.l., diagrams and 6. ' Fluid issues from the apparatus cooled by the amount of work, performed by the thrust.
• This apparatus consists of an apparatus as shown on Fig.3 and Fig.4 which is herein already described, except that the converging inlet duct 1 is here substituted, pre erably, with a converging duct 12 suitable for supersonic speed and the addition of an outlet diffuser 13.
• Cowling 14 is formed to suit supersonic speed.
• velocity distributions in important sections of apparatus are diagrammatically illustrated above Fig. 5.
• air enters inlet duct 12 where it increases its pressure and reduces velocity reaching in the narrow throat sonic velocity W-, which in combination with the speed U results in velocity V.. reactive momentum of which acts against propulsion.
• W- reduces to W p causing by this the increase of absolute velocity from V-, to V p .
• Air is exhausted from the apparatus cooled by the amount of work performed by the thrust, m- (J j - W 2 ) « U, and there is not any jet of air streaming in rearward direction behind the apparatus.
• velocities 1 and Y are sonie velocities at which the air has not ,the same temperature. Since at supersonic speed the demand on power is very high, the heat contained by the air may be insufficient, in this case some external heat must be added. This can be done by arranging a burner, preferably in the wider end of duct 2, adding the heat to the air by burning of fuel.
• the thrust is controlled by the valve 16 turning of which, by-the shaft 17, restricts the passage for the fluid.
• the herein illustrated and described propulsion apparatuses can be used for linear propulsion when they are attached to vehicles like ships, aircrafts, fast moving trains and so on, or hey can be used for circular propulsion, driving a rotor of power generators which will generate power by the heat extracted from the atmosphere or water.
• propulsion apparatus 22 driven by the propulsion apparatus of this invention.
• propulsion apparatues 22 are attached to the arms 23 which are rigidly connected with the shaft 25 constituting the rotor 24 of a power generator.
• This power generator resebles, to some degree, a windmill with the difference that here instead the wind the heat extracted from the fluid, air or water, drives the rotor.
• each apparatus 22 rams fluid and forces it to flow through the apparatus generating by this a propulsion force which drives the rotor and generates power.
• the apparatuses 22 are preferably bent as shown to follow the circular path.
• each apparatus In order to control the speed of rotation, each apparatus is pivotally connected to the arms 23 freely rotating on pins 27.
• centrifugal force deflects the rear of each apparatus away from the centre of rotation deflecting by this the inlet of the apparatuses from the direction of rotation resticting by this the fluid to enter the apparatus and this in turn reduces the thrust which drives the rotor.
• Said deflection of apparatus is kept in balance by the ties 28 which are pivotally attached to the apparatuses 22 and to the bush 29 which can freely rotate on the shaft 25. By rotating the bush 29 all apparatuses can be deflected together as required.
• Bush 29 can be rotated manually or it can be controlled automatically by a suitable conventional governor.
• Speed of the power generator can also be controlled by choking the flow of fluid as is illustrated and described on Fig.9.
• apparatuses 22 will be rigidly connected to arms 23 and each apparatus will be connected by a pipe, 18 on Fig.9, to a central container located, preferably, in the vicinity of and rotating with the shaft 25. Fluid will be introduced into said container through a valve which can be controlled by a suitable conventional governor or manually.
• Shaft 25 of power ' generator rotates in bearings 30.
• propulsion apparatuses and the power generator may be modified to suit particular requirements.
• described and illustrated means for controlling the thrust can be made interchangeable,
