Research on aircraft performance, particularly using open models and open data, is integral to advancing the aviation sector. My research focuses on developing and improving OpenAP and associated open tools that supports the study of trajectory optimization and predictions.
Highlights
OpenAP: Open Aircraft Performance Model
This project focuses on the development of OpenAP, a comprehensive Open Aircraft Performance and Emission Model. OpenAP aims to provide a fully open-source platform for modeling critical aircraft performance metrics, including kinematic properties, thrust, drag, and fuel flow rates. Built on the principle of transparency and accessibility, OpenAP is founded on open data and designed to advance air transport research. The repository houses a rich collection of OpenAP databases, along with a Python implementation that streamlines data access and facilitates complex aircraft performance computations. Overall, OpenAP serves as a transparent and accessible tool for fostering rigorous and collaborative research in air transport.
OpenAP.top: Open Flight Trajectory Optimizer
Presenting a fully open-source trajectory optimizer, providing researchers with seamless access to the sophisticated yet efficient direct collocation optimization approach. The optimizer is capable of adjusting to meteorological conditions and can be utilized for distinct flight phases independently or in combination. It encompasses conventional fuel and cost index objectives, as well as climate metrics-based objectives utilizing global warming or temperature potential.
