Abstract:
A combustion management device for generating a thrust burst to impart a physical impulse. In operation, a combustion chamber, defined by a valve unit (33), is primed to a set pressure and fueled by fuel injectors (23). An ignitor (22) then initiates combustion. Under force of combustion, the valve unit is moved, pulling an exhaust valve (18) from an exhaust port (16), releasing combustion products as thrust. Work may be derived from the travel of the valve unit, independent of the thrust generated. After combustion, a return mechanism returns the valve unit to the start position, ready to repeat the process. Simple design, and valve operations needing little more than pressure differentials to function, make for simplified construction, and more modular applications.

Abstract:
A planer hexagon curve extruded to a center point providing six isosceles triangle panels with the shortest edge being one of the six planer hexagon curves forms a buckyball hexagon extrusion that naturally provide pentagon extrusions. A buckyball hexagon extrusion is one of twenty that array at equidistant angles around twelve pentagons at equidistant angles in groups into an open cell buckyball sphere. A closed cell buckyball within a larger open cell buckyball sphere share a common center point and other extrusion angles that have utility for: a water paddle wheel for propulsion that floats, a tire, a wind turbine, and an air turbine.
Abstract:
An efficiency enhanced turbine engine and method for a turbine engine having a rotor (25) and a fluid flow path (31) that extends through compression (63), combustion (65), and expansion (67) or turbine stages with fluid flowing through the fluid flow path driving the rotor. The turbine engine has one or more stator-rotor-stator (24-25-24) assemblies, and uses a flat rotor disk with turbine blades (57/58). Capturing of fluid during combustion enables elevation of the temperature and pressure while maintaining the fluid at near constant volume during combustion. Fluid is caused to reenter the rotor a plurality of times to provide cyclic exposure of the moving parts of the turbine engine to different portions of the engine cycle for reducing the average temperature of the moving parts and thereby allow higher compression ratios and combustion temperatures.
Abstract:
A pulse combustor system for efficiently operating a pulse combustor. The pulse combustor system includes the pulse combustor and a duct. The pulse combustor has a combustion chamber defining an internal space, a conduit having a first end in fluid communication with the internal space and a second end in fluid communication with an environment outside of the pulse combustor system, and a fuel injector configured to inject fuel into the internal space of the combustion chamber. The duct has two openings, with one opening disposed adjacent to the second end of the conduit. The pulse combustor system has an average operating frequency, and the duct has a length that is about one quarter of a wavelength corresponding to the average operating frequency. The pulse combustor and the duct each has a central longitudinal axis, and the two axes are substantially aligned.

Abstract:
Two identical impact turbines with intermittent combustion are arranged in parallel in a common.housing. Air is compressed by intake fans due to centrifugal compression, fuel is injected and ignition is assured with spark plugs. Exhausted working fluid leaves the apparatus via a common outlet. The two turbine wheels are interconnected via giears and have a single power output shaft.
Abstract:
The turbines and the single one play an active role during the pressure, the bursting and exhausting process; they have closed sides which are fixed together into the head. The wings are joint together and they close the space between the tube and the turbines. Pressure is obtained through the centrifuge-force and the intaking propellers which are assembled on the sides of the turbines. Either the two tubes or the single one are in the centre of the turbines whereas the single turbine has a 90° angle tube referring to the turbine and between the tube and the turbine there is a centesimal space. Among all the parts which are fixed together there is no friction.
Abstract:
The invention relates to an internal combustion engine which combines the processes of a 4-stroke- and turbine-engine. The combustion engine includes a turbine (1), a housing (2) and a ringshaped piston (3) relatively movable in a ringshaped combustion chamber which is surrounding the turbine blades (1a). A mechanical coupling for synchronizing the reciprocating motion of the piston with the rotary motion of the turbine is located between the turbine and the piston. The engine preferably fulfills the 4-stroke cycle in one revolution. The combustion engine is also characterized in that it is simple, sturdy and has favourable low speed rotation characteristics. The engine has a clean combustion fulfilling severe environmental requirements without the use of a catalyst.
