Abstract
In this article, the process of changing a turbofan engine to an engine for use in marine transportation is investigated. From the production power of the modified engine, it is possible to supply the propulsion power and power needed by boats and ships. In the first stage, the turbofan engine is simulated, and after validation with the original model, the fan is removed from the turbofan engine. The changes caused by removing the fan are studied on the engine components and then by applying the new conditions, the output power of the engine derived from the engine is calculated. In the following, with the installation of the flow guide vane, new conditions prevail over the downstream components of the engine. In this case, by applying the new conditions, the engine output power is evaluated along with other quantities. According to the obtained results, after removing the fan from the turbofan engine, the efficiency of the compressor decreases, but with the installation of the flow guide vane, this loss is compensated and the output power of the engine is increased. Also, the effect of increasing the inlet temperature to the engine is studied in two cases without the flow guide vane and after its installation. Based on the results obtained in this part, the flow guide vane increases the production power and reduces the specific fuel consumption in different modes.
