High pressure hot gas generator for turbines

Claim 1

A high-pressure hot gas generator and turbine combination comprising: a. air compressor means including an air cylinder and air piston; b. combustion means including a combustion cylinder and combustion piston, said air cylinder and combustion cylinder being coaxially aligned along a given axis; c. interconnecting means including a common rod securing said air piston and combustion piston together for simultaneous movement along said given axis, said air piston moving in a direction to compress air in said air cylinder when said combustion piston is moving under pressure of combusting gases towards its expanded position; d. diesel-type fuel injection means for said combustion means, ignition taking place upon complete compression of injected fuel and air when said combustion piston is in its compressed position, said diesel-type fuel injection means including a fuel pump coupled for operation to said interconnecting means; e. air pressure responsive inlet and outlet valve means in said air compressor means; f. air inlet and gas outlet means in said combustion means, said air pressure responsive outlet valve means in said air compressor means communicating with said air inlet means in said combustion means, and said outlet means in said combustion means being open, when said combustion piston is moved to its expanded position; and said air pressure responsive outlet valve means being blocked from communication with said air inlet means, and said outlet means being blocked when said combustion piston is moved to its compressed position, whereby hot combustion gases are scavenged through said outlet means when said combustion piston is in its expanded position, said hot combustion gases being under high pressure; g. a turbine connected to receive said hot combustion gases; h. a turbofan driven by said turbine; and i. a cowling surrounding said turbofan, turbine, air compressor means and combustion means to guide airflow from said turbofan over said combustion means and at least partially into air receiving means for said air inlet means thereby providing a turbofan-type engine, in which effective turbine cycle pressure ratios in excess of 100 to 1 can be realized, said air compressor means including at least four air cylinders and four air pistons and said combustion means including at least four combustion cylinders and four combustion pistons, two of said air pistons and associated axially aligned combustion pistons being in opposed relationship along said given axis and two others of said air pistons and associated axially aligned combustion pistons being in opposed relationship along an axis parallel to and laterally spaced from said given axis; said intercoupling means further including a shaft axially positioned between and parallel to said given axis and said axis laterally spaced from said given axis, said shaft having a tilted bearing; and a wobble spider having a journal bearing receiving said tilted bearing and having at least two opposite laterally extending arms coupled to opposed pistons such that wobbling of said spider interlocks motion of said opposed pistons so that movement of said first mentioned opposed pistons is 180* out of phase with movement of said other two opposed pistons.
