P a g e 1 | 3 Aviation Science (1507NSC) Assignment 1 – Mechanics of Flight Weight: 20% of course Style: Article & video Length: One article-report 1500 – 2000 words (single-spaced 12 font) and four 1 min videos Marking: It will be marked out of 100. During the lectures, you learned that there are four main forces (usually called airborne forces) acting on an aircraft while it is flying: • The Lift (FL) acting vertically upwards, • the Gravitational Force or Weight (FG), acting vertically towards the Earth, • the Thrust of the engine (FT), pulling horizontally forwards, and • the Drag (FD), acting horizontally backwards. Each of these vector forces may act in different ways depending on the flight stage that we consider: take off, climb, cruise, approach or landing. Task: Write an article-report analysing the Physics dynamics of flying. Assume that your report is to be used to train some of your colleagues at work who have not completed a degree of aviation. You are requested to: I. Explain in scientific but straightforward terms, the equilibrium conditions of an aeroplane cruising. II. Explain how tailplanes can help balance and control those conditions of equilibrium. Following you will find guides that will help you to write your report. They include specific questions that you must cover and calculations that you must complete as guiding examples. PART I: Equilibrium conditions In your report, you must include answers to the following questions using the information from your lectures or any other external sources appropriately referenced: • Identify the airborne forces as vectors acting on the aircraft. Where on the aircraft (with respect to its centre of mass) each of these forces act?, What is the common name for those positions?, e.g. the Gravitational force acts on the centre of gravity which on Earth coincides precisely with the centre of mass of the aeroplane. • Include an original free body diagram and an original extended free body diagram representing the ideal disposition of the four main forces acting on an aeroplane during the five different stages of flight. Explain your diagrams and describe the effect of each of these forces in the aeroplane translation and rotation. Include the angle of attack. You can use the table at the end of this document P a g e 2 | 3 • Using your diagrams, establish what are the translational and rotational conditions of equilibrium of these four forces during the cruise stage? Write down and explain the equations that determine these conditions. • Are these four forces likely to change in value or to move their position of action during the flight? If they do, under which conditions do they vary? What are the effects of those changes? Exemplar calculations for real-life situations Using M to be the last digit in your snumber and N the first two digits. (e.g. s1234567, N=12 and M=7) Record a 1min video showing and explaining how to solve the following real life situation • The inertia of an aeroplane is M x103kg. It carries N passengers with average inertia of 60 kg at a certain constant speed in cruising flight, the ratio of lift to drag of the complete aircraft is 6 to 1 ( ?? ?? = 6 1 ) What are the values of the lift, thrust and drag? Use your free body diagrams and equations of equilibrium to solve this problem. PART II: Tailplanes and the difficulties in balancing the four forces while cruising • How does the ideal disposition of the four forces in an aircraft relate to the nose-up or nose-down pitching moments? What are the difficulties that the pilot can face to maintain such an ideal disposition for each of the forces while cruising? • Do these forces values and positions depend on the airspeed and the angle of attack? How? • Would it be beneficial for the pilot to control the position of action of these principal forces? What positions are controllable? What would happen if all the forces were concentrated in the centre of mass all the time? Would this affect the ability to manoeuvre the aircraft? • What is a tailplane? What is the effect of a tailplane in the dynamics of the aircraft? Why is it usually called lifting tail? Why is it also called stabiliser? Compare the characteristics of the adjustable tailplane and the slab tailplane in a table. Include photographs of aircraft with such tailplanes. • How does a tailplane act in an aircraft designed for routine flight? For high speeds? For low speeds? The force exerted by the tailplane is called the lifting-tail load (FLT) include this vector force in a new extended free-body diagram for each speed case in cruise mode. Evaluate and explain the new conditions of equilibrium and express them mathematically. Exemplar calculations for real-life situations Using m to be the first digit of your snumber and n the last digit(e.g. if s=1234567, m=1and n=7). Record a 1 min video showing and explaining how to solve the following real life situation. Include detailed and explained working out to solve this problem. Use your free body diagrams to help you find a solution. Identify the translational (x and z) and rotational (y and z) conditions of equilibrium. Introduce these problems as exemplary applications of the concepts discussed in this part: • An aeroplane of m x104 kg mass is designed with the line of thrust n x10-1m above the line of drag. In routine flight the drag is 15.2kN, and the centre of pressure on the main plane is 200mm behind the centre of mass. If the centre of pressure on the tailplane is 12m behind the centre of mass, what is the lifting-tail load (FLT)?

Physics dynamics of flying
The shape of an aeroplane wing makes air move faster over top of it. The pressure of air goes down when it moves faster. So there is less pressure on the top of wing than there is on bottom. The difference in pressure causes a force on wing that pushes it up into air. In aerodynamics, four different forces come together: lift, weight, drag,
and thrust. The opposite of weight is lift, which happens when air moves over wings. The total weight of an object is part of its weight force. The force of gravity pulls weight down. Lift, thrust, drag, and weight are four forces.Marcello R. Napolitano(2000),lift keeps a Frisbee in air as it moves through air.
Flight dynamics is study of how to steer and control an air vehicle in three dimensions. Roll, pitch, and yaw, which are angles of rotation of three main axes of an aircraft around its centre of gravity, are most important flight dynamics parameters.
When plane forces balance, it's in equilibrium. Level flight shows this.
Lift, weight, thrust, and drag affect flight. Force has size and direction, hence it's a vector. Balanced forces on an object result in no net force and equilibrium. Newton's first law of motion asserts that a stationary item stays stationary and a moving object stays moving unless pushed. Without external force, an object's speed remains constant.
In theory, a plane in flight should produce no net external force. Lift equals weight, and thrust equals drag. A cruising airliner is an example. Fuel burnt reduces aircraft weight, however the difference is negligible. The cruise airspeed is constant.
Using the wind's relative speed, we can calculate a cruise plane's ground speed. Vector addition equals ground speed to airspeed plus wind speed. The plane's motion is literal. With a constant ground speed, it's straightforward to calculate an airplane's range, or how far it can fly on a given quantity of fuel.
Changing throttle or wing angle of attack unbalances forces. Newton's second law of motion can be used to calculate aircraft's acceleration.
Net force is sum of all forces acting on a body. Objects in equilibrium have zero net force. Newton's first law of motion states that an item in equilibrium moves at a constant speed since there is no net force acting on it.
A tailplane, also called a horizontal stabiliser, is a minor lifting surface positioned on tail after an aircraft's primary lifting surfaces. Tailplanes aren't on all fixed-wing aircraft. To be statically stable in pitch, tail must create downforce against a nose-down pitching moment. More speed increases downforce, less speed lessens it. In steady-state flight, when opposing pressures are balanced, aeroplane is "in trim." At a certain airspeed and "force configuration," this is called "trim speed." In connection to tailplane, speed above trim speed causes nose to tilt up due to excessive downforce, which forces it move uphill and slow down to regain equilibrium. When speed is below trim speed, plane pitches down to find equilibrium. In a real plane, it overshoots its equilibrium point multiple times before reaching Phugoid oscillation.
Part 1
1.Four factors keep an airplane's wings aloft. They propel or slow a plane.
· Thrust propels an aeroplane forward. A propeller, jet engine, or rocket creates it. Air is drawn in and pushed out. Fan is an example.
· Drag opposes motion. Slows things down. Air pressure and friction generate drag. Put your hand out a moving automobile window to feel it draw back.
· Gravity produces weight.
· Lift keeps an aeroplane aloft. Wings provide much of an airplane's lift.
Four forces affect plane in distinct ways. Each force has a counterforce. Weight...
