INDEXING SCHEME FOR ASPECTS RELATING TO NON-POSITIVE-DISPLACEMENT MACHINES OR ENGINES, GAS-TURBINES OR JET-PROPULSION PLANTS

Description

F05D is an indexing classification for cross-referencing technical aspects applicable to non-positive-displacement machines, gas turbines, and jet-propulsion systems that are detailed in other subclasses within F01–F04. This classification facilitates navigation of innovations involving continuous-flow engines, turbomachinery, and aerospace propulsion by mapping common design features, control methods, and operational characteristics across the broader engine classification scheme. It does not itself describe specific technologies but rather serves as a navigational tool to locate related subject matter distributed throughout the fundamental engine and pump classes.
