Project overview

A Year in the Making

The PLR-19 Express is a versatile, multirole aircraft designed to operate efficiently across both cargo and passenger missions. Conceived for standard airport and austere environments, it balances long-range capability with high payload capacity and all-weather reliability.

Over the course of a full academic year, our team of aerospace engineering students went through a conceptual design process. This included mission requirements analysis, iterative sizing, aerodynamic analysis, structural sizing, propulsion integration, and systems design.
