Abstract-The use of Ontologies in the present is becoming very common and widely used in different education areas, some areas of the engineering such as aerospace, can improve with the application of this informatics tools. Classification of aircraft as an object and al his components has become an important research area for the statistics analysis previous of designing a new concept, in this document we are going to explain, how Fluent Editor can help the designer to improve the classification and information analysis used to choose the statistical characteristics of the new concept. On this paper is showed an ontology of aircraft engines. Databases are created for storing, processing, performing calculations, sorting, sampling and presentation of data arrays according to various criteria. Then the created array of data on aircraft engines can be further used as a basis for selecting the engine according to the technical task.
