Project Description: Vehicles landing on Mars, vehicles returning to Earth, and drop shipments for soldiers in the field must land without crashing to prevent the smash-up of equipment and contents. Parachutes are one of the deceleration devices used to accomplish this. This project’s goal is to contribute to the design and optimization of deceleration devices to produce landings soft enough to keep equipment and contents intact.
Pioneer Aerospace specifically sought out University of New Haven faculty and students. The University of New Haven designed and ran computational models, comparing the results to existing experimental data based on varying altitudes and speeds. When the comparison of results validated the model, the model was then set to run at altitudes and speeds for which there is no existing data. Pioneer Aerospace will use those results to make design decisions that take into account how a vehicle or object may behave at these altitudes and speeds.
As part of the project, students modeled vehicles to understand how the flow of air past the vehicle affects the deceleration device. Models of simplified geometries — i.e., flow over cylinders or spheres — were conducted and extrapolated to more complicated models, such as an actual spacecraft or a complex parachute.
This project is on-going and students interested should contact Dr. Carnasciali to find out about current opportunities.
