台灣在世界五軸加工機械上的份量

8 世界航空科技未來驅勢

9 航空產業特性與專有名詞：金字塔型生產體系、中心衛星工廠、高門檻、高科技、回收慢、適航認證(Airworthiness)、BASA(Bilateral Airworthiness and Safety Agreement)、Offset、GOCO、Dry Lease vs. Wet Lease、FAA vs. EASA、MRO、FAR、NADCAP、MIL等。

10 Three Technology Areas that May Drive Future Aeronautics Innovation:
Exploiting Computational Advances for High-fidelity Simulation and Multidisciplinary Design (or MDO) Removing the Constraint that Aircraft Must be Designed Around Pilots or Passengers Designing the System rather than the Vehicles: Collectives and Systems of Systems

11

12 Blended-Wing-Body, BWB

13 Characteristics of BWB
L/D increase by 20% Low fuel burn High environmental compatibility Low operating cost High operational flexibility for airlines Difficult to escape from aircraft within 90 seconds (ICAO Annex)

14

15 Man is No Longer the Measure of All Things Aeronautical:
Unmanned Aerial System (UAS) or RPAS Micro Air Vehicle (MAV) Mesicopter – Centimeter-scale Rotorcraft Micro-Sailplanes, Solar-powered Aircraft, etc.

16 Future economic return? 未來產值?

17 Collectives, Multiagent Systems, and Systems of Systems in Aeronautics:
Miniature Trailing Edge Effectors (MiTEs): small tab placed near the trailing-edge of an airfoil on the lower or upper surface oriented perpendicular to the airfoil chord line (as shown) Formation Flight – Induced Drag Saving of about 40% Chevron Engine Engine Cover Vortex Generator Fuel Cell Battery Laminar Flow Control

19

20 Collectives, Multiagent Systems, and Systems of Systems in Aeronautics:
BWB Cargo Aircraft Civilian Air Re-Fueling Ceramic Matrix Composite (CMC) Distributive Electric Aircraft Propulsion (DEAP) Superconducting Devices is Key Post-stall Civilian Aircraft Performance Bio-fuel is Gone?

21 Current Industrial Design
Surface mesh for modern RANS LES computation Typically 50 million flowfield grid points

22 Other Major Themes Composite materials Structural analysis and design
Structural dynamics and aeroelasticity Fatigue and fracture Flight control – fly by wire Air traffic management Safety Human factors Noise UAVs Climate change

23 ICAS Workshops 2005: Towards a Global Vision on Aviation Safety and Security 2007: UAV-Airworthiness, Certification and Access to the Airspace 2009: Aviation and Environment 2011: Advanced Materials and Manufacturing-Certification and Operational Challenges 2013: The More Electrical Aircraft: Achievements & Perspectives for the Future 2015: Complex Systems Integration in Aeronautics

24 2005 & 2007 Aviation Safety and Security Achievements
Goal for 2020: Traffic Amount Double and Accident Rates Become ¼ Compare to 2000 Point-to-Point vs. Hub-and-Spoke Near Future: B787 & A350XWB UAS or RPAS: Military A/C First and Commercial A/C Later, Cargo Transport First and Passenger Transport Later

25 2009 Aviation and Environment
Greener: Air Pollution & Noise Pollution Aviation Industry only produce 2~3% of World CO2 Emission, But take a Lion’s Share of Blame NOx Emission is Less Than Expected Noise Sources: Engine, High Lift Devices, Landing Gear System Condensation Trail (Contrail) will produce Cirrus, and induce Climate Change, thus needs to vary the Cruise Altitude Future Fuel Burn should reduced 50% Still about 15% Wasted Efficiency in Operation

26

27 2011: Advanced Materials and Manufacturing – Certification and Operational Challenges
Composite application on airframe has been increasing Typical examples are Boeing 787 & A350XWB Composites cannot currently demonstrate prominent advantage in cost & weight in small commercial airplane, such as MRJ Technical challenge against weight reduction Example: Lightning strike damage: difficult & costly tests, at a gateway of accurate numerical simulation If high development costs remain in composites, aircraft industries may go back to aluminum again!

28 2013: The More Electrical Aircraft: Achievements & Perspectives for the Future

29 EU Flightpath 2050 > 75% less CO2 emissions
> 90% less NOx emissions > 65% reductions in perceived noise > Aircraft is designed and manufactured to be recyclable > Emission-free taxiing > 90% of all journeys (door-to-door within the EU) within 4 hrs > Flight arrived within 1 min. of planned time regardless of weather > 80% less accidents > ATM should handle at least 25Million flights/year

30 Zero-emissions Concept – The Ce-Liner (M∞~0.7)

31 Future 2050 Asian Plan? Area includes Mainland China, Taiwan, Hong Kong/ Macau, Korea, Japan, Singapore, and Southeast Asia > 70% less CO2 emissions > 80% less NOx emissions > 60% reductions in perceived noise > Emission-free taxiing > 80% of all journeys (door-to-door within Asia) within 4 hrs > Flight arrived within 5 min. of planned time regardless of weather > 80% less accidents > ATM should handle at least 30 Million flights/year
