16.886 - Feb 3, 2004 Agenda • Drivers - Commercial and Military Cargo Transport Needs • Responses - Conventional and Advanced Concepts • Formation Flight - A Possible Approach – Basic concepts – One flight result – Other considerations • Plan for the semester • Questions and responses – Turn in Student Profile and Preferences at end of class

16886-Feb3,2004 Commercial drivers Globalization trends Longer distances between producers and consumers Emerging markets, e.g. China, South America, Africa Lean manufacturing Focus on to eliminate waste, e.g. JIT Faster response to market demands Air freight operators looking for new markets Most transoceanic freight shipped by surface Gap in capability-"middle market Ship is inexpensive but takes 18-30 days Air is expensive but takes only 3-6 days Operating economics drive Increased capacity per air freighter Reduced crew and fuel costs

16.886 - Feb 3, 2004 Commercial Drivers • Globalization trends – Longer distances between producers and consumers – Emerging markets, e.g. China, South America, Africa • Lean manufacturing – Focus on “flow” to eliminate waste, e.g. JIT – Faster response to market demands • Air freight operators looking for new markets – Most transoceanic freight shipped by surface – Gap in capability- “middle market” • Ship is inexpensive but takes 18-30 days • Air is expensive but takes only 3-6 days • Operating economics drive – Increased capacity per air freighter – Reduced crew and fuel costs

16886-Feb3,2004 Commercial trends Bartowski(FedEx)"Future Concepts for Air Cargo Delivery, AIAA Paper 2003-2629 Freighter fleet expected to double in 20 years 90%of fleet capacity in wide-body aircraft in 20 years leading to 23% grown in payload capacity Growth is in the middle market" between air and surface for world wide freight market Analysis of Future Air Cargo Demand in China Jiang et al MIT ICAt), Market and Infrastructur Air cargo growth through China airports expected to grow at 11.2% per annum for next 20 years Includes both domestic and import/export

16.886 - Feb 3, 2004 Commercial Trends • Bartowski (FedEx) “Future Concepts for Air Cargo Delivery”, AIAA Paper 2003-2629 – Freighter fleet expected to double in 20 years – 90% of fleet capacity in “wide-body” aircraft in 20 years leading to 23% grown in payload capacity – Growth is in the “middle market” between air and surface for world wide freight market. • Jiang, et al (MIT ICAT), “Market and Infrastructure Analysis of Future Air Cargo Demand in China” – Air cargo growth through China airports expected to grow at 11.2% per annum for next 20 years. Includes both domestic and import/export

16886-Feb3,2004 Commercial trends- Contd Allison, et al"Expedited Transport Airlines", Final Report for 16.899 Air Transportation System architecting World air cargo and freight to grow at 6.4-6.5%per year for next 10 years Total worldwide freight shipping expected to go from 132 to 383 Freight- Ton-Kilometers in 20 years Freighter Fleet to grow from 1, 775 to 3, 078, including retirement of 1, 228 old freighters, mostly narrow body ong range freighter segment will be the fastest growing Standard shipments take 4-6 days with only 10-15%time in the air. Most the time is ground transport, handling, waiting Top 10 markets will generate 40% of global airfreight in next 10 years Intra asia, China→ Europe, China→ North america, North America台→ Asia, Europe o> Asia, North America Europe, DomestIc USA Lots of good data in this report from last year's class

16.886 - Feb 3, 2004 Commercial Trends - Cont’d • Allison, et al “Expedited Transport Airlines”, Final Report for 16.899 Air Transportation System Architecting. – World air cargo and freight to grow at 6.4-6.5% per year for next 10 years. – Total worldwide freight shipping expected to go from 132 to 383 Freight￾Ton-Kilometers in 20 years. – Freighter Fleet to grow from 1,775 to 3,078, including retirement of 1,228 old freighters, mostly narrow body. – Long range freighter segment will be the fastest growing – Standard shipments take 4-6 days with only 10-15% time in the air. Most the time is ground transport, handling, waiting. – Top 10 markets will generate 40% of global airfreight in next 10 years: Intra Asia, China ⇒ Europe, China ⇒ North America, North America ⇔ Asia, Europe ⇔ Asia, North America ⇔ Europe, Domestic USA Lots of good data in this report from last year’s class

16886-Feb3,2004 Military Drivers Threats are global Reaction times are shorter Trends are towards Us basing for security, economic and political factors Result is US forces are becoming more expeditionary Rumsfeld's Transformation goals for Army Deploy 1 division anywhere in the world in 5 days Deploy 5 divisions anywhere in the world in 30 days Division is 16, 000 personnel and all their equipment Long range bombers based on continental US require considerable tanker support which is expensive and logistically complicated We need more information on military drivers

16.886 - Feb 3, 2004 Military Drivers • Threats are global • Reaction times are shorter • Trends are towards US basing for security, economic and political factors • Result is US forces are becoming more expeditionary • Rumsfeld’s Transformation goals for Army – Deploy 1 division anywhere in the world in 5 days – Deploy 5 divisions anywhere in the world in 30 days • Division is 16,000 personnel and all their equipment • Long range bombers based on continental US require considerable tanker support which is expensive and logistically complicated. We need more information on military drivers

16886-Feb3,2004 Summary of Drivers Both commercial and military Need more weight and volume transported over long distances Mostly intercontinental Need "block times"in days rather than weeks Ground transport and handling is important Focus on integrated system, not just aircraft Need affordable costs More expensive than surface but less expensive than current air

16.886 - Feb 3, 2004 Summary of Drivers • Both commercial and military – Need more weight and volume transported over long distances. – Mostly intercontinental – Need “block times” in days rather than weeks • Ground transport and handling is important • Focus on integrated system, not just aircraft – Need affordable costs • More expensive than surface but less expensive than current air
