Abstract: The present disclosure describes an improved vehicle wheel rotation apparatus. The apparatus 300 comprises a combustion chamber 301, one or more turbines (302,311) and at least one non-return valve 306. An auxiliary attachment 305 is retrofitted at surface of each bar 304 present in each turbine. The auxiliary attachment 305 comprises 3-tube arrangement, wherein two tubes (305a, 305b) of the attachment 305 enable entry of jet of exhaust gases into the attachment 305 and further facilitate the plurality of bars 304 for initiating rotation of the runner 303. The jet of exhaust gases, exiting the attachment 305 through last tube 305c, comprises reducing cross-section near opening, enabling further increment in velocity of exhaust gas, resulting in thrust to the bar 304 to which the attachment 305 is already fitted, thus providing additional rotations to the runner 303 and eventually to one or more wheels of the vehicle.

Abstract: The stud-oriented valve (50) includes a valve main body (8) which is housed in a lamination duct (7) and which exhibits a closure axial face (10) which can rest on a duct closure seat (11) for isolating a lamination cavity (4) from a combustion chamber (5), said body (8) also having a centering peripheral surface (12), an opening axial face (13) which may rest on a chamber-side valve stop (14), and at least one orientation stud (15) which protrudes from the opening axial face (13), said stud (15) being capable to slide through a guide axial orifice (17) that is fixed to the lamination duct (7).

Abstract: An engine timing input system is described for pulse detonation engines that allows for accurate engine timing when rotary or cylindrical valves are used to distribute an air/fuel mixture for combustion. The invention uses a profile disk having a predetermined circumferential edge corresponding to valve position to provide for accurate engine timing. A frequency wheel is used in conjunction with the profile disk to provide a more accurate representation of valve position by partitioning the valve position into multiple pulses during each rotation of the rotary or cylindrical valve. The profile disk and frequency wheel when used with programmable timing circuitry signal fuel valve timing and ignition relative to the rotating valve.

Abstract: A turbine based engine that includes a mixture chamber, a combustion chamber, a stationary flow control barrier, and a turbine. The stationary flow control barrier is located between the combustion chamber and the turbine. The arrangement allows the system to provide precisely measured and mixed fuel and oxidant mixtures to the mixture chamber where it is burned to produce the expandable gas product that will be expanded through the turbine to turn the turbine and produce shaft output power. A preferred embodiment of the engine includes a pair of turbines mounted symmetrically about an expeller along a single shaft.
