## Aircraft Configuration Examples:  Short-Haul Civil Tiltrotor (SHCT) Project

## SHCT Benefits to CapacityResults of 1999 FAA Newark Airport Task Force Study

- Of all the airport improvements examined (except for a new runway) the Tiltrotor using SNI operations, provided the greatest benefit.
- In annual delay reduction costs, Tiltrotor would save $700M, a new runway $950M

##  Active Tiltrotor Noise Reduction

- Achieved a 7.0 dB BVI noise reduction from baseline XV-15 blades
- Used closed-loop HHC with blade pressure transducers for feedback
- Follow-on test
- Verify results and expand test conditions
- Microphone mounted on RTA for feedback
