Abstract:

This project sought to address the use of multiple parachutes used in entry descent and landing systems by exploring a single canopy solution for planetary entry. The proposed design utilised a metamorphic (shape changing) canopy to provide a two stage variable drag profile. A prototype metamorphic parachute was produced and tested in a subsonic wind tunnel to validate the feasibility and drag profile of the initial design, followed by a flight test to evaluate operation in free stream conditions. The project successfully tested and validated this metamorphic parachute concept, demonstrating the increase in drag generated before and after the change in morphology. Results from testing showing a 0.35 change in the coefficient of drag from first stage (open crown) to second stage (closed crown). It has also generated valuable data to support further research of the concept, clearly indicating the areas for development in future iterations of the metamorphic parachute concept.
