NASA National Aeronautics and Space Administration NASA Automated Repair Approaches for AAM By Dr. Pankaj Dhussa

1. Automated Repair Approaches for AAM
ULI IMOCAS PT2.3
Challenge and Opportunity
- Urban Air Mobility (UAM) vehicles are considered a next step in air travel
- Repair is currently manual, time consuming, hazardous, and expensive.
- Automated repairs of composite structures may streamline this process
Expected Impacts
- 80% automation of repair process
- Reduce AAM downtime and lower ticket costs
- Information fed into Operational Analysis Tool
