Fundamentals of aircraft flying

Introduction

Man has always wanted to fly. Legends of the early evidence of this desire. Perhaps the most famous of these legends is the Greek myth a father and son who flew with wings of wax and feathers. It was not, however, until the successful flight of the discomfort Wright Kitty Hawk, North Carolina, that the dream of flying come true. From flight at Kitty Hawk, aircraft designers have spent considerable time and effort in developing this machine first oil in a modern aircraft today. To understand the principles of flight, you must first familiarize themselves with the physical laws that affect the aerodynamics.

LAWS affecting physical

AERODYNAMIC

Learning Objective: Identify the physical laws of aerodynamics to include Newton's laws of motion and the Bernoulli principle. Aerodynamics is the study of forces that allow you to fly an airplane. You should carefully study the principles set forth here. Whether your job is to fly the aircraft and / or maintenance, you must know why and how a plane flies. Know why and how you can purchase aa functions effectively.

Laws of Motion

The movement is the act or process of changing place or position. In short, movement is movement. An object may be moving relative to a fixed object on the other. For example, a person sitting on a plane flying at 200 mph is at rest or without motion relative to the plane. However, the person is moving on air or land. Air did not force or power other than the pressure when it is stationary. When the air moves, its strength becomes apparent. An object moves in the still air has a force exerted on it following his trade. There is no difference in the effect, if an object moves relative to the air or the air moves over the object. The following information explains some basic laws movement.

Newton's first law of motion

The first law of motion Newton (inertia), an object at rest remains at rest or an object in motion continues moving at the same time and speed in the same direction until an outside force acting on it. For an aircraft to shoot or fly, a force must be applied. It will remain at rest without an external force. Once the aircraft is moving, another force must act on it lead to a stop. Continue to operate without an external force. This desire for an object to remain at rest or motion to continue is called inertia.

Newton's second law of motion

Second law of motion (force) provides that if an object moving with uniform velocity is subjected to an external force, the change in motion (acceleration) is directly proportional to the amount of force and inversely proportional to the mass of the object moved. The proposal will take place in the direction which it acts. In short, this means that an object that is pushed by 10 pounds of force will travel faster than you would if you were pushed by 5 pounds of force. Heavy object will accelerate more slowly than a lighter object when a force is applied evenly.

Third Newton's law of motion

The third law of motion (action and reaction) states that for every action (force) there is a reaction equal and opposite (force). This law can be demonstrated with a world. If a balloon is inflated with air and release it without securing the neck, as air is expelled the balloon moves in the opposite direction of the air rushing out of him.

'S principle Bernoulli

Bernoulli's principle states that when a fluid flowing through a tube reaches a constriction or narrowing of the tubes, the speed fluid passing through the constriction increases and decreases the pressure.

Aerodynamics

Learning Objective: recognize the terms used to describe different parts of an airfoil and the terms used to explain the generation of airflow lift. A profile is defined in the context of an aircraft elevator or other aerodynamic effect desirable as it travels through air. Wings and the propeller of a fixed wing aircraft and rotor blades of a helicopter are examples of profiles.

Aerodynamics TERMINOLOGY

The shape of a wing and its relation to airflow are important. The following are the most common terms that you must understand before knowing profiles. advanced to the front or on the surface of aerodynamics. Borde The outlet edge or rear surface of aerodynamics. Acordes A straight line from edge to edge of a wing flight. camber curve or departure of a straight line (line string) of leading to trailing edge of aerodynamics. wind on the direction of airflow compared to the wing. angle of attack angle between the chord line and relative wind.

Airflow around a wing

The generation of a lift on the wing depends on the wing to create an air flow special in the air stream. This pressure air flow is developed on the aerodynamic surface elevation. As the relative wind strikes the edge of the wing, the airflow is divided. Part of the relative wind is deflected upward and backward, and the rest is diverted downward and backward. RAPPER U airfoil surface is inclined to him, his flowover surface is disturbed. This disturbance causes awavelike effect to the airflow. The lower surface is relatively flat theairfoil. The flow of air through your surfaceisn't interrupted. Lift is accomplished by this flow of air through the differencein airfoil.This low pressure area is caused by air that is interrupted by the curvature of the wing, and is the key lifting. There is less pressure on the upper surface of the wing than there is on the lower surface. The air pressure pushes on the surface lower. This pressure difference causes the wing to rise. Now you know that the lift is developed by the difference between the air pressure on both the top and bottom of the wing. Although there is less pressure on the upper surface and pressure on the lower surface of a wing, an aircraft has a lift. Levante is one of the forces that affect the flight.

Forces affecting VOL

Learning Objective: Recognize the four fundamental forces that act on a plan. An airplane is flying the center of an ongoing battle forces. The conflict of these forces is the key to all the maneuvers in the air. No nothing mysterious about these forces, which are defined and known. The direction in which each of these events can be calculated. The aircraft is designed to take advantage of each force. These forces are lifting the weight, thrust and drag.

LIFT

Lift is the force that acts in an upward direction of support aircraft in the air. It counteracts the effects of weight. Lift must be greater than or equal to the weight if the flight is sustainable.

WEIGHT

Weight is the force of gravity acting downward on the aircraft and the crew of the aircraft, fuel and goods.

DIG

Thrust is the force generated by the engine of the aircraft. It acts in the positive direction. Thrust must be greater or equal to the effects of dragging the flight to begin or continue.

DRAG

Drag is the force that tends to keep a plane back. Drag is caused by the interruption airflowabout wings, fuselage (body), and all protruding objects on the map. Drag resists motion in which it operates in parallel and in reverse direction with the wind. At this stage, you learn the physical laws of aerodynamics, wings, and forces that affect the flight. To understand flight, you must learn about the axes of rotation of an aircraft.

Axis rotation

LEARNING OBJECTIVE: Identify the three axes of rotation and the terms relating to the aircraft rotation around these axes. All vehicle, a boat, car or an aircraft is able to make three primary movements (pan, tilt and orientation). The vehicle has three rotational axes are perpendicular (90 degrees) to each other. These axes are referred by their longitudinal, lateral and vertical. Perhaps the reference is more descriptive than the action takes place around since the axis or roll pivot, height and orientation.

Axis longitudinal

The longitudinal axis is the pivot point on which an aircraft rolls. Movement-related deployment is described as the movement of wingtips (one above and below the other). This axis is moving forward the rear full length (nose to tail) of the aircraft. This axis is parallel to the main direction of the aircraft. The main address of a fixed wing aircraft is always forward.

LATERAL AXIS

The lateral axis is the pivot point on which the locations of aircraft. Pitch can be better described as the movement up and down the nose of the aircraft. The launch axis extends from left to right the aircraft (wing tip to wing tip). Perpendicular and cut the roll axis.

VERTICAL AXIS

The vertical axis from top to bottom of an aircraft. It is perpendicular to both axes of roll and pitch. Movement associated with this axis is oriented. Diversion is best described as the change in aircraft heading right or left main direction of an aircraft. Suppose you're walking from your workspace to plan, located at 100 meters. You try to walk straight, but can not because there is a strong wind blows off course on your right. This movement is the right direction.

Helicopters and fixed wing aircraft

Learning Objective: Recognize thedifference aerodynamic principles applyto fixed and rotary wing aircraft Fixed aircraft.A motionfor depends on the elevation of the front. Aircraft rotary wing depends rotatingairfoils for uplift. Airfoil sections of a fixed wingaircraft are not symmetrical. Ahelicopter The rotor blades are symmetrical. These differences areimportant parameters you if you understand aerodynamicprinciples.

Fixed wing aircraft

You've learned about the laws of physics and the forces that affect the flight, the wing rotation axis and an aircraft. Now we will apply these principles a fixed-wing aircraft in flight. First, the motion must exist. The movement is ensured by the thrust developed by the engine of the aircraft. This is achieved by the force exerted by the exhaust of an aircraft or by the action of the propeller blades of an airplane propeller. The thrust is greater than the force of inertia and, as the fixed-wing aircraft accelerates, air flows through the wings. The relative wind striking the leading edge of the wing is divided and flows through the upper and lower surfaces. The curvature of the upper surface acts as a constriction, which accelerates the airflow and reduces air pressure. The lower surface is relatively flat, does not speed or air pressure. There is less air pressure on the upper surface of the wing on the lower surface. The fixed-wing aircraft in the air rises. Now that the device is safe in the air, the axes of rotation in question. If the nose of the aircraft increases, Attack of the angle changes. Change the angle of attack causes the aircraft to rotate on its axis side or height. If you lower terms of the right wing, left wing rises. The plane moves along its longitudinal axis or roll axis. Suppose that the aircraft is flying straight and level. There is a strong wind hitting the nose of the plane on the left side, pushing the nose to the right. This makes the tail of the plane to go left, and the plane can be rotated on its vertical axis or yaw. All these forces are needed for the flight to begin or continue.

What to do if you see a low flying aircraft passenger?

I live in Milton Keynes, England and today I see the rotary engine of four planes wing (I think that's what you call them) flying just above the houses was only 50 feet in the air What should I do? It was a big plane and I live nowhere near an airport.

Duck and hope!
