This paper presents shortly reasons of improving designs and de scribes general methods of making moditications of turboprop and turboshaft engines. The theoretical analysis of methods of modifying, concerning general changes of efficiency, flow, and rating. So, the influence of the following factors on engine performance was presented: change of quality unit functioning factors, increase of compression and flow rate by using a compressor zero-stage; changes of gas temperature keeping the gasgenerator rotational speed by adjusting the minimal throat area of turbine nozzle guide vanes; modelling; and changes of rotational speeds of operational ratings.
