Análise integrada de desempenho de aeronave com grupo motopropulsor pistão-hélice aplicado ao Ipanema EMB-202

Abstract

This work consists of the conceptual development of the performance analysis of a piston propeller powered aircraft, applied to the Ipanema EMB-202. The aircraft model was chosen due to its significance in the national agricultural aviation market and for being the first to be certified for operation with biofuel. Thus, used as a case study to evaluate the performance of propulsive variants that use Aviation Gasoline and Hydrated Ethanol fuel, in the different phases of flight. Therefore, a performance analysis is carried out by aeronautical product, dividing the development chapters into: Propeller Performance, Engine Performance and Aircraft Mission Performance. In each chapter, is presented the development of the set of equations that model the physics of the treated problem. Accordingly, to approach the propeller performance, a simplified method derived from aerodynamic equations that define the behavior of the propeller is applied; to approach engine performance, thermodynamic equations are used to describe the engine operation cycle, and chemical equations to describe the fuel burning reaction used by the engine; to approach the performance of the aircraft, a set of aerodynamic and motion mechanics equations are applied according to each mission segment. Hence, computational tools were developed to assist in the calculations developed and to provide graphs that allow a better understanding of the influence of the various parameters on the product’s performance, and consequently on the flight phase. The computer programs responsible for the treatment were written in MATLAB and EXCEL. Thereby, the information obtained allows a better understanding of the interdependence of products on individual performance, the main parameters that impact the performance of the aircraft and the impact on the mission depending on the used fuel type.
