Aeronautical Science Perspective Paper

2358 words - 9 pages

ABSTRACTThis paper will attempt to discuss the basic aerodynamic principles of flight. It will be based on Module 3, Learning Objective 1: 'For a typical aircraft, describe the functions of the structure and the flight controls. Apply aerodynamic principles to explain how flight controls control pitch, roll, and yaw'. It will also outline the basic control surfaces of an aircraft and the primary and secondary effects of each of them. In addition, it will also explore Bernoulli's Principle and the forces acting on an aircraft in flight.Table of ContentsList of FiguresFigure 1: The Magic of Flight 3Figure 2: Main Components of an Airplane 4Figure 3 : The Wing And Aerofoil 5 Figure 4 : Aerofoil Nomenclature 6Figure 5 : Bernoulli's Principle 7Figure 6 : Forces on An Airplane in Flight 8Figure 7 : The 3 Axes of Rotation 9Figure 8 : 6 Degrees of Freedom 10Figure 9 : Control Surface: Ailerons 11Figure 10 : Control Surface: Elevators 11Figure 11 : Control Surface: Rudders 11IntroductionFigure 1: The Magic of FlightMan has come a long way since the advent of the first heavier-than-air flight by the Wright brothers back in 1903. In the span of merely a century and a decade, we have achieved an astounding feat of aeronautical capability. From the biplanes of WW2 to the successful launch of NASA's Space Shuttle orbiter, Man's thirst for the quest of achieving airborne flight with the birds has always been a source of great admiration and fascination. Those of us who were "bitten" with the 'flying bug' from a very young age can vouch for the sheer thrill and adrenaline rush of rolling down the runway in an insane but fulfilling roller coaster ride as we defy the clutches of Gravity and rise up into the clouds; a step closer to the heavens. It is, truly, a magical feeling to be able to soar in the skies in absolute freedom, throwing our Earthly worries away and entering a whole new world altogether. And while the picture above is a humorous attempt in showing how airplanes fly, it does not really explain the Physics behind the Laws of Aerodynamics. The 'magic' of flight as shown above can actually be explained and involves juxtapositions of Daniel Bernoulli's principles, who, in 1738 investigated the forces present in a moving fluid; as well as Newton's 3 famous Laws that govern most of Physics. The basic principles of flight are outlined in this paper, and are generally similar for many different kinds of fixed wing aircraft, big or small, that you may see flying out of the airports today.Main Components of an AirplaneFigure 2: Main Components of an Airplane.The figure above shows the main components of an airplane and its respective parts. The airplane can generally be divided into 3 main parts, namely the Fuselage, Empennage and the Wing.Fuselage - The fuselage is also known as the main body of the airplane. This houses the cabin where the passengers sit, and in some airplanes, also houses the storage space for luggage, goods, and other forms...
