aircraft propulsion design relies on modularity and evolving technologies. The main scope discussed is the future of successful aircraft engine design for the mass transportation market. For strategic technology insertion, the effects of introducing hybrid electric propulsion systems in modern day passenger aircraft will be analyzed.

Different engine modularity and its limitations will be briefly discussed and how it will affect the product development process. Scope and approach give a breakdown on the product lifecycle and when to insert new technology for a successful outcome.
