4. Smarter ways of Constructing a Flow Path

5. Two Major Steps in Creation of Turbine Develop a new blade designs based on Ideal Fluid Conditions – A generalized Procedure. Modify the design details for Real Fluid Conditions.

6. Basic Rules for Design of A Real Turbine More customized rules along with the general rules. Customized rules are specific to application: Radial Vs Axial. In Reality: Design analysis of A Real Machine is an Exclusive Scientific Art. Define and evaluate a series of correction factors.

7. The Duty of airfoil in the Role of Turbine Blade

8. Effect Based Description

9. Calculation of lift force The lift force L is determined by integration of the measured pressure distribution over the airfoil’s surface. where, p i = surface pressure distribution, p  = pressure in the free-stream U ∞ = free-stream velocity,  = air density (temperature), c = airfoil chord

10. Definition of lift and drag Lift and drag coefficients Cl and Cd are defined as:

11. Can We Identify the Cause? Which is best for describing how aircraft get the needed lift to fly? Bernoulli's equation or Newton's laws and conservation of momentum?

19. Giffard’s Air Ship

20. The Shocking News The New York Times wrote that maybe 1 million to 10 million years they might be able to make a plane that would fly ?!?!?! People had dreamed of flying for many years. The United States Army was trying to develop an airplane in 1903, but the plane wouldn't fly. Only eight days later two men were successful in flying the first manned plane. Controlled, powered flight had seemed impossible until Orville Wright took off on the 17th December 1903. They were Wilbur Wright and his younger brother, Orville.

22. Kate Carew Interviews the Wright Brothers “Are you manufacturing any racing machines?” “Not just now, but we intend to.” “How much can I buy one for?” “Seven thousand five hundred-dollars.” “Is that all? It doesn’t seem like an outside price for a perfectly good airship?” “Airship!” shouted the Wright brothers indignantly. “Is that the wrong word?” “An airship,” said Wilbur contemptuously, “is a big, clumsy balloon filled with gas.” “Well, I don’t see why your biplane shouldn’t be called an airship, too.” “It’s a flying machine,” said Wilbur. “The name we prefer is ‘flyer,’” said Orville. “An airship would cost $50,000,” said Wilbur. “More like $150,000,” said Orville, and they argued the question.
