- ÍtemFabricación e instalación de una toma auxiliar de aire para el carenaje del motor de la aeronave t-90 calima para obtener un mejor rendimiento del sistema de refrigeración.(Fundación Universitaria Los Libertadores. Sede Bogotá., ) Agudelo Ortiz, Johnny Ventura; Angulo Ávila, Jorge IvánThis thesis proposes a solution to the repetitive increase in temperature of the oil used for the cooling and lubrication of the engine and its components, during the different phases of flight recorded by the "Flight Data Recorder” and for the flight reports by the pilots. The information obtained by these two sources indicates that during ascents, maneuvers at low speeds and high angles of attack, including traffic for landings and takeoffs, the temperature indication is in red arc (+ 235 ° F / + 113 ° C ), according to cruise flight reports da indication in green arc ( Max. 180 ° F / Max. 82.22 °C ), but this indication is very close yellow arc (+181 °F/ + 83 °C - 235 °F/ 113 °C ), on land after 25 minutes of operation the temperature indication is in arc red (+235°F / +113°C). As a first step, an analysis of the position of the radiator and the cooling system components (air intakes, hoses and sensors) identifying that the main causes of the increase in temperature were the position of the radiator behind the engine cylinders and the lack of a current of clean air of thermal residues. The solution proposed in this degree project contemplates the manufacture of a series of three supports for the change of position of the radiator and the implementation of a NACA-type air intake in the lower fairing of the T-90 Calima aircraft which aims to cool the radiator and optimize the aircraft cooling system, thus achieving heat dissipation residual resulting from the combustion produced inside the engine, preventing the Excessive overheating of it and of the lubricating oil. getting thus a safe operation of the aircraft during the phases of takeoff, flight and landing.
