The Advanced Supersonic Parachute Inflation Research Experiments (ASPIRE) project was launched in 2016 to develop a capability for testing supersonic parachutes at Mars-relevant conditions. Three parachute tests successfully tested two candidate parachute designs and qualified a parachute for NASA’s Mars 2020 mission (that successfully delivered Perseverance rover to the surface of Mars in Feb 2021). To achieve Mars-relevant densities, these parachutes were deployed at targeted conditions at high altitudes over Earth, launched via sounding rockets. ASPIRE Flight Tests provided valuable data on parachute inflation, forces, and aerodynamic behavior. Design of the flight tests depended on flight mechanics simulations which in turn required aerodynamic models for the payload, and the parachute. Computational Fluid Dynamics (CFD) was used to generate these models pre-flight and they are compared against the flight data after the tests. This talk will go over some aspects of the test design, development of pre-flight models, and comparison with flight test data.
