  3. Presentation Overview The Aerospace Industry Today

  4. The Three Basic Components of Our Business Should be Viewed as an Integrated Whole Technology & Product Development Process Development/ Enhancement Workforce Development (People issues) The best Technology and Processes in the world are useless without the right People to develop and employ them.

  5. John’s Twin Professional Passions Education Airplanes Technical Workforce Development + Engineering Education (Reform) + Airplane Design (and Aerodynamics) • “Hobbies” • Paleontology • Archaeology • Cultural • anthropology • Cognitive • psychology

  6. A “System of Systems” Approach to Issues Important to The Boeing Company [John’s Current “Job Description”] Aerodynamics (Low-Speed, High Lift) • Motivation • Knowledge • retention Airplane Design [“Systems Engineering”] Biomechanics of Flight (Reynolds Number Scale Effects) Technical Workforce Development (Programs and Processes) • Motivation • R&D leverage • Recruiting • Improved preparation • for professional practice, • Positive company image • Enhanced: • Motivation • Utilization • Productivity • Retention Technical Education (Enhancement & University Relations) HEIB Target: A Large-Scale Systems Integration (LSSI) – capable technical workforce. Future Technology Development Opportunities.

  7. John’s Projects and Research (1955-Present) 1950s 1960s 1970s 1980s 1990s 2000 - present Boeing (1976) Human-powered Flight High-Lift System Aerodynamics Model Airplanes Hang gliders DARPA/NASA Morphing Aircraft Programs V-22 “Osprey” Vortex Generators High-Reynolds Number Wind Tunnel Design Sailplane Aerodynamics and Design Guided Missile Design (USAF) Robot Pterosaur (2) & “Smart Wings” Wind Turbines NASA Airplane Design Contract Tent Design • Transonic Flow • in Turbines & • Compressors • Multi-disciplinary • Optimization • Large Surface-Effects • Vehicle Design • Architectural • Aerodynamics • Drag Reduction on • Inter-city Buses Robot Pterosaur(1) Under-Sea Gliders Engineering Education

  8. The Curriculum Vitae of an AerodynamicistJohn H. McMastersTechnical FellowBoeing - Seattle Once upon a time there was a mother duck and a father duck who had five baby ducklings. The first was a really ugly duckling who knew that one day he would probably grow up to be a swan. Well, the really ugly duckling never did grow up – he only matured into just a really ugly duck. And so it goes (going on 87). John at age 21 “He had only one vanity, he thought he could give advice better than any other person.” Mark Twain (writing about John McMasters)

  9. Basic Premises “It is suicidal to create a society dependent on science and technology in which hardly anyone [aside from a small, numerate elite] knows anything about science and technology.” Carl Sagan “The scientist discovers that which exists, the engineer creates that which never was.” Theodore von Kármán

  10. Non-Systems Thinking In a Global Environment “I’m sure glad the hole isn’t in our end…” Thanks to Peter Synge

  11. Professor McMasters illustrates his famous brain-stapling technique in a seminar for compulsive thinkers. “It’s all about thinking, dummy” A. Einstein “Thinking is the one skill that never becomes obsolete.” Paul B. MacCready Thanks to Gary Larson The Far Side

  12. The Airplane Business Today • Aerospace was a “poster child” for technological progress for much of the 20th century • Now considered a “mature industry” with a spate of studies decrying its“declining state” in the U.S. [despite recent signs of new prosperity] • end of the Cold War globalization • a sense of “been there, done that” • explosive growth in other newer technologies (IT, bio-, nano-) • competition for resources (money and talent) • We need to replenish a rapidlyaging technical talentpool (particularly in design and “systems engineering”) • Uncertain long-termconsequences of globalization, the war on terrorism, environmental concerns, resource limits, etc.??

  13. Experimentation The Traditional View of Aviation History Proliferation Realization Inspiration Farther, faster, higher

  14. Absolute Airplane Speed Record(As One Measure of Progress in the First Century of Flight) Lindberg crosses Neil Armstrong Atlantic on the Moon Wright Bros. Hypersonic ~25 years ~ 40 years SR-71 Jets Mach 1 Commercial Transports “Farther, faster, higher”
