Design of turbo-compressor type of internal-combustion rotary engine (TIRE) was made. The design is the hybrid of conventional internal combustion engine and gas turbine. Design of engine reminds gas-driven turbine, because it has compression pump, turbine and combustion chamber. Operating principle is similar to conventional engine because it has not uninterrupted but portion process of fuel combustion. Operating principle: working mixture is compressed by the compressor and directed to the combustion chamber. In the combustion chamber it is ignited and through the outlet ports is directed to the turbine rotor and makes it rotate. Turbine rotor rotates engine shaft, from which useful output is removed. The working model of engine was made and preliminary tests were carried out. Results showed that the engine needs same improvements.
