  2. Outline • Aerospace Systems, Concepts, and Analysis Competency • Programs/Technology Contribution to Goals • Aviation System Analysis Capability

  3. Atmospheric Sciences Competency Helps Assess Aviation’s Impact on Environment Emission Measurements Assessment Modeling Radiative effects of Contrails

  4. The Three Pillars for Success (Aero-Space Technology Enterprise)

  5. Three Pillars Aero-Space Goals NOISE Reduce the perceived noise levels of future aircraft by a factor of two from today’s subsonic aircraft within 10 years, and by a factor of four within 20 years. SAFETY Reduce the aircraft accident rate by a factor of five within 10 years, and by a factor of 10 within 20 years. EMISSIONS Reduce emissions of future aircraft by a factor of three within 10 years, and by a factor of five within 20 years. COST OF AIR TRAVEL Reduce the cost of air travel by 25% within 10 years, and by 50% within 20 years. CAPACITY While maintaining safety, triple the aviation system throughput, in all weather conditions, within 10 years. GENERAL AVIATION Invigorate the general aviation industry, delivering 10,000 aircraft annually within 10 years, and 20,000 aircraft annually within 20 years. SUPERSONIC TRAVEL Reduce the travel time to the Far East and Europe by 50 percent within 20 years, and do so at today’s subsonicticket prices. DESIGN & TEST Provide next generation design tools and experimental aircraft to increase design confidence,and cut the development cycle time for aircraft in half. SPACE ACCESS Reduce the payload cost to low-Earth orbit by an order of magnitude, from $10,000 to $1,000 per pound, within 10 years, and by an additional order of magnitude within 25 years. IN-SPACE TRANS. Reduce the cost of interorbital transfer by an order of magnitude within 15 years, and reduce travel time for planetary missions by a factor of two within 15 years, and by an order of magnitude within 25 years.

  10. Notional Concept of a Safety Data Analysis Framework Technologies/Interventions • Time Slice (2007, 2022) • Fleet projection • Accident projection Option #1 Option #1 Option #1 Option #N • • • Accident Rates (Metrics) Additional Metrics: Fatal Accident Rates Number of Fatalities Number of Injuries

  11. Aviation Safety Goal Analysis • 34 Technology Datasheets considered in Safety Goal Analysis • -- 20 from Aviation Safety Program Office • -- 2 from Airframe Systems • -- 6 from Propulsion Systems • -- 1 from Advanced Subsonic Technologies • -- 5 from Aviation Operations Systems • Approximately 47 Different Causal Factor Impacts • Technology impacts to different aircraft classes analyzed separately (Transports, Commuters, GA, Rotorcraft)

  12. Aviation Safety Goal Analysis - Transport Aircraft (Part 121) Goal Approach • Reduce the aircraft accident rate by a factor of 5 within 10 years, and by a factor of 10 within 25 years. • U.S. only, 1990 to 1996, fatal & non-fatal accident NTSB data used to determine percentage of accidents/fatalities/injuries avoided due to technology implementation • U.S. fleet projections based on FAA and DOT forecasts • 100% overlap in accident coverage allowed due to multiple technologies impacting individual accidents; consistent with AvSP philosophy of increased reliability through redundant technology impacts Metrics • Accident Rate (Fatal & Non-Fatal Combined) • Fatal Accident Rate • Number of Fatalities • Number of Injuries

  13. Aviation Safety Goal Analysis - Commuter Aircraft (Part 135, sch. and non-sch.) Goal Approach • Reduce the aircraft accident rate by a factor of 5 within 10 years, and by a factor of 10 within 25 years. • U.S. only, 1990 to 1996, fatal & non-fatal accident NTSB data used to determine percentage of accidents/fatalities/injuries avoided due to technology implementation • U.S. fleet projections based on FAA and DOT forecasts • 100% overlap in accident coverage allowed due to multiple technologies impacting individual accidents; consistent with AvSP philosophy of increased reliability through redundant technology impacts Metrics • Accident Rate (Fatal & Non-Fatal Combined) • Fatal Accident Rate • Number of Fatalities • Number of Injuries
