Who We Are

Chevrons - The Road From Idea to Deployment

Systems Assessment: 2001-2005• Ground-test evaluation in engine test stands • Flight evaluation in relevant environments

Fundamental Research: 1996-2000• Computational and experimental research to develop a

fundamental understanding of the fluid mechanics governing the effectiveness of the concept

• Development of practical implementations (chevrons)

Seedling Idea: 1994-1996Basic studies on jet mixing suggest that tabs can

enhance jet mixing, with the potential to reduce noise

Initial service entry, 2002

The U.S. Air Force Research Laboratory's Automatic Collision Avoidance Technology Fighter Risk Reduction Program (ACAT/FRRP) team, which includes NASA's Dryden Flight Research Center, won an Aviation Week & Space Technology magazine Laureate Award for its successful development and flight test of an Automatic Ground Collision Avoidance System.

2008 Collier Trophy Winner: The Commercial Aviation Safety TeamFor achieving an unprecedented safety level in U.S. commercial airline operations by reducing risk of a fatal airline accident by 83 percent, resulting in two consecutive years of no commercial scheduled airline fatalities.

2007 Collier Trophy Winner: The Automatic Dependent Surveillance-Broadcast (ADS-B) Team of Public and Private Sector Groups For conceptualizing, developing, and initially implementing the next generation performance-based air-ground, ground-air, and air-air surveillance system.

UH-60A Airloads Tests of blade pressures, loads, deformations, rotor performance and rotor wake visualizations were successfully completed May 2010 in collaboration with the Army in the NFAC 40x80ft wind tunnel. The UH-60 wind tunnel team has won the American Helicopter Society's Grover E. Bell Awardfor "encouraging research and experimentation in helicopter development."

Aviation’s Economic Impact in the U.S.

The aviation industry is vital to the nation’s economic well-being

• Aviation directly or indirectly provides 953,000 Americans with jobs

• In 2007, aviation manufacturing and services accounted for $477B in direct and indirect economic activity

• In the U.S., more than 60 certified domestic carriers operate every day

– They operate more than 6500 aircraft – They service 1.7 million travelers daily on 23,000

flights– In 2010, they had an annual operating revenue for

commercial flights of $131B

• In 2010, aviation provided the nation with a trade surplus of $43.6B
