Who Is Your Instructor? Cal Poly, Pomona ARO graduate-1986. 30 years of experience in air vehicle flight control system design and systems engineering. I am here to teach you, challenge you, and help you become an effective aerospace engineer.
Engineering Ethics & Grading Statistics - Do the right thing for humanity. Satisfy customers.
Working in teams. Protect your country/company’s work as a competitive edge. Protecting your competitive edge in school. About cheating. Discuss the grading curve & use of statistics (x-bar and sigma). You can always calculate your standing in the course!
Cal Poly Philosophy: Learn By Doing – Term project: Wind tunnel experiment on an elliptical wing. (Optional extra credit: Build/fly RC aircraft to collect flight performance data.)
Basic Concepts of Aerodynamics – AIRSPEED is the key! Lift & Drag.
Cruise flight & the four balanced forces:(Lift=Weight)&(Thrust=Drag) @constant Airspeed.
= “q-bar” = (½) 
V 2 = (½)

PM 2
All aerodynamic forces (Lift, Drag, etc.) are proportional to dynamic pressure!
Systems of Units (English & SI) – Mass-Length-Time (MLT) fundamental units. Force as a derived measure [F]=[M*L/T 2 ]. Hudson’s Rule #3 for taking an engineering exam:
CHECK UNITS FOR ALL EQUATIONS! Many errors will be due to inconsistent units!
Anatomy of a Typical Airplane – Fuselage . Wing (root, tip, wingspan, airfoil section, ailerons, flaps, slats). Empennage (horizontal stabilizer+elevator, vertical stabilizer+ rudder). Powerplant . Flight Instruments – “Basic T” = Airspeed, Attitude, Altitude, &
Heading.
Important Events In The History Of Flight – MORE QUESTIONS ASKED & ANSWERED!
