What is it about?
Aircraft designers are working to make aviation more sustainable, and propeller-driven aircraft are gaining renewed interest because they can be more fuel-efficient and better suited for hybrid-electric propulsion. However, propellers create complex airflow patterns that affect how an aircraft flies, especially its stability and control. This research introduces a new framework called the Standard Model ITA (SMI), which helps engineers study these effects early in the design process, even before detailed geometry or wind tunnel data are available. By using interchangeable aircraft models and simplified aerodynamic tools, the framework makes it easier to predict how propellers will influence flight dynamics. The goal is to support smarter, more sustainable aircraft designs from the very beginning by saving time, improving safety, and helping the industry move toward cleaner aviation.

Why is it important?
Designing sustainable aircraft requires making smart decisions early in the development process. But when it comes to propeller-driven configurations, engineers often lack the tools to predict how propellers will affect flight stability and control before detailed models or test data are available. This research fills that gap. It provides a practical framework that helps designers understand complex aerodynamic effects caused by the propeller installation right from the start, like slipstream on the airframe and non-uniform inflow at the propeller. By doing so, it supports cleaner, safer, more efficient aircraft designs and helps reduce development risks and delays. In short, it’s a step toward making sustainable aviation not just possible but also practical.
Perspectives
As an engineer deeply committed to sustainable aviation and aerospace education, I have always believed that the path to cleaner flight begins with smarter design decisions and reliable information. This research is my way of contributing to that future by equipping designers with practical insights and accessible tools to understand how propellers influence the aircraft flight from the earliest stages of development. Working in the industry and studying as a part-time grad student at ITA, I have seen firsthand how time constraints and limited data may hold back innovation. I have also noticed that these challenges are not fully shared or addressed within academic circles. That is why I created the SMI framework aiming to bridge the gap between aerodynamic theory and practical engineering, and to help make sustainable aircraft not just possible, but achievable. And last note: propellers are just fascinating!
