Abstract
A continuous combustion rotary engine (100) is provided for powering such vehicles as aircraft, boats and automobiles with an efficiency which approaches the total expansion of combustion gases. The continuous combustion rotary engine (100) includes a plurality of power stages (110, 130 and 150) for sequential progressive expansion of combustion exhaust gases in order to generate rotative forces on a plurality of main rotors (112, 114, 132, 134, 152, 154). Simultaneously, the driven rotors (112, 114, 132, 134, 152 and 154), acting in pairs, progressively compress air for use in supporting the continuous combustion in the central portion of the expansion section (92) within stage (110). The use of the same rotors to both be driven by the expanding combustion gases and compress the inlet air provides the instrumentality for cooling the rotors, the heat transferred therefrom serving to increase the efficiency of the compression process. Continuous combustion rotary engine (100) further includes a synchronization assembly (200) for maintaining the main rotors (112 and 114, 132 and 134, 152 and 154, as well as 176 and 178) to be meshingly engaged without the respective flutes (113 and 115, 133 and 135, 153 and 155) from coming in contact with each other.
