Contemporary aeronautical constructions require applying systems of drive transmission based on gear units. Trends in development of aeronautical gears assume diminishing weight of the gear retaining its basic features which are; the possibility of transmitting high load and reliability. The article presents an analysis of criterion for choosing constructional solutions for aeronautical multi-power path gear units. A few criteria were chosen for the analysis: constructional solutions of aircrafts (planes, helicopters), constructional solutions of engine- moment receiver system and a kind of applied drive. Because the field of issues connected with aeronautical drive transmission systems is very wide, the material and technological factors were not taken into account. They are a subject of separate analysis. The main aim of the presented analysis is determining the criterion for choosing constructional solutions of drives based on existing solutions which allow for implementing new solutions for newly developed aeronautical constructions on the prototype stage. Modernising existing constructional solutions is difficult to put into practice because of procedures followed in the aeronautic industry. That is why the carried out analysis aims at preparing solutions for research on the stage of making a virtual and demonstrative prototype. The final effect of such analysis and research can be developing a solution for gear unit parts assuring the possibility of transmitting a given moment while diminishing, for example, weight in comparison to gears which are produced nowadays. This factor is extremely important for parts of aeronautical constructions.
