Engine for Aeronautical Applications II

Abstract

An improved engine for aeronautical applications includes a forged cylinder block having a drive device rotatably mounted therewithin and a motive device for rotating the drive device, the motive device including two cylinder banks in a V-type configuration and a plurality of cylinders mounted within the cylinder banks for producing power and rotating the drive device. The forged cylinder block further includes a plurality of cylinder cavities formed in the cylinder banks and the upper approximately one-third of each of the cylinder cavities is generally surrounded by a generally toroidal cooling chamber, and the lower approximately two-thirds of each of the cylinder cavities is generally free of any surrounding cooling chambers. Finally, a coolant circulation device in fluid transmission connection with each of the cooling chambers is operative to circulate cooling fluid therethrough whereby the upper approximately one-third of each of the cylinder cavities is cooled by the cooling fluid.

1 . An improved engine for aeronautical applications comprising:
 a forged cylinder block having a drive means rotatably mounted within said forged cylinder block and motive means for rotating said drive means, said motive means including two cylinder banks in a V-type configuration and a plurality of cylinders mounted within said cylinder banks for producing power and rotating said drive means;   said forged cylinder block further including a plurality of cylinder cavities formed in said cylinder banks;   the upper approximately one-half to one-fourth of each of said cylinder cavities generally surrounded by a generally toroidal cooling chamber, the lower approximately three-fourths to one-half of each of said cylinder cavities being generally free of any surrounding cooling chambers; and   coolant circulation means in fluid transmission connection with each of said generally toroidal cooling chambers for circulation of cooling fluid therethrough whereby said upper approximately one-half to one-fourth of each of said cylinder cavities is cooled by said cooling fluid.   
   
   
       2 . The improved engine of  claim 1  wherein said coolant circulation means includes a pair of coolant pumps which drive said cooling fluid into said forged cylinder block and said engine circulating said cooling fluid through said cooling chambers and through coolant flow cavities machined into said cylinder block, said cooling fluid flowing out through water out manifolds from said cylinder block and said engine to a radiator for dissipation of heat therefrom, said cooling fluid then flowing back to said pair of coolant pumps for recycling of said cooling fluid through said coolant circulation means. 
   
   
       3 . The improved engine of  claim 2  wherein said engine further includes a cylinder head deck, said cooling fluid coming into direct contact with said cylinder head deck via said coolant flow cavities, said engine free of any cylinder block deck which would interfere with cooling fluid contact with said cylinder head deck. 
   
   
       4 . The improved engine of  claim 1  further comprising a plurality of cylinder sleeves each inserted into and lining one of said plurality of cylinder cavities, each of said plurality of cylinder sleeves generally lining and sealing the lower two-thirds of said plurality of cylinder cavities, with the upper approximately one-third of each of said plurality of cylinder sleeves inwardly spaced from said cylinder cavity thus forming said generally toroidal cooling chamber surrounding each of the cylinder sleeves when mounted within each of said plurality of cylinder cavities. 
   
   
       5 . The improved engine of  claim 3  further comprising a set of gas-filled metal “O”-rings mounted between said cylinder head deck and said cylinder block thereby generally preventing coolant and lubrication fluid leaks from said engine. 
   
   
       6 . An improved engine for aeronautical applications comprising:
 a forged cylinder block having a drive means rotatably mounted within said forged cylinder block and motive means for rotating said drive means, said motive means including two cylinder banks in a V-type configuration and a plurality of cylinders mounted within said cylinder banks for producing power and rotating said drive means;   said forged cylinder block further including a plurality of cylinder cavities formed in said cylinder banks;   the upper approximately one-third of each of said cylinder cavities generally surrounded by a generally toroidal cooling chamber, the lower approximately two-thirds of each of said cylinder cavities being generally free of any surrounding cooling chambers;   a plurality of cylinder sleeves each inserted into and lining one of said plurality of cylinder cavities, each of said plurality of cylinder sleeves generally lining and sealing the lower two-thirds of said plurality of cylinder cavities, with the upper approximately one-third of each of said plurality of cylinder sleeves inwardly spaced from said cylinder cavity thus forming said generally toroidal cooling chamber surrounding each of the cylinder sleeves when mounted within each of said plurality of cylinder cavities; and   coolant circulation means in fluid transmission connection with each of said generally toroidal cooling chambers for circulation of cooling fluid therethrough whereby said upper approximately one-half to one-fourth of each of said cylinder cavities is cooled by said cooling fluid.   
   
   
       7 . The improved engine of  claim 6  wherein said coolant circulation means includes a pair of coolant pumps which drive said cooling fluid into said forged cylinder block and said engine circulating said cooling fluid through said cooling chambers and through coolant flow cavities machined into said cylinder block, said cooling fluid flowing out through water out manifolds from said cylinder block and said engine to a radiator for dissipation of heat therefrom, said cooling fluid then flowing back to said pair of coolant pumps for recycling of said cooling fluid through said coolant circulation means. 
   
   
       8 . The improved engine of  claim 6  wherein said engine further includes a cylinder head deck, said cooling fluid coming into direct contact with said cylinder head deck via said coolant flow cavities, said engine free of any cylinder block deck which would interfere with cooling fluid contact with said cylinder head deck. 
   
   
       9 . The improved engine of  claim 8  further comprising a set of gas-filled metal “O”-rings mounted between said cylinder head deck and said cylinder block thereby generally preventing coolant and lubrication fluid leaks from said engine.
