Turbocharging is a prevalent method for the promotion of an UAV flight level without having to make major changes in its engine. It depends on the correct selection and precise control of the turbocharger. Today, the mathematic simulation of the engine cyclic processes as a strong tool to estimate performance and reduce costs and testing time is taken into consideration. In this research multi-zones thermodynamic modeling according to the following steps is performed. At the first step, a geometrical model of the Wankel engine is developed and the geometrical characteristics of the equivalent reciprocating engine is achieved. At the second step, the equivalent reciprocating engine is simulated by GT-Power commercial software. Then, using the empirical results of dynamometer tests the developed model is vitrificated and by this means the effect of altitude conditions on the engine performance is studied. At the last step, according to the matching theories, a proper turbocharger is selected and by using appropriate control mechanisms, the performance of the turbocharged engine at the desired altitude is evaluated. Results indicate that for the operating engine speed and full load condition, turbocharging leads to 41% power increment and 5% specific fuel consumption reduction at the target altitude compared to the naturally aspirated engine at designed working altitude.
