How an Aircraft Flies – Lesson 1
Before we discuss space let’s start on earth. How did we ever get from walking around banging deer on the head and eating them, to flying across the globe at 600mph?
An aircraft is an air machine that has the ability to fly. It achieves this by the support gained from the air or the atmosphere generally. The aircraft has the ability to counter the force of gravity. This is made possible because the aircraft uses the dynamic lift or the static lift of the airfoil. The jet engine is also significant in inducing the upward thrust.
The general activity that surround the aspects of aircraft is commonly referred to as aviation. The aircraft is flown by a qualified pilot like the ones at Cloudbase. The aircraft is controlled by onboard computers.
The Science Behind Flying
Flight has always amazed the human over many years and they are left amazed on how it could possibly be achieved. In 1903 the Wright Brothers pulled out what was considered inevitable ,but over the years it has improved and also got better. Thanks to the advancing technology in the aviation sector. Now if you want flying lessons surrey, you can ring up and have them within hours!
For heavy flights to take place in the atmosphere, there are basic criteria have to be met. Four forces has to be employed in order to play a crucial role. They include, lift, weight, thrust and drug.
The aircraft uses the principle of buoyancy in order to float on air. This is the same way the ship is also able to float on water. This contains large airbags or canopies that are filled with helium, hot air or hydrogen. These gases are relatively less dense than the surrounding air. This explain the floating concept of the plane on the air. For this concept to work, the Newton’s Law of Physics has to be employed.
Newton’s 3rd law of in physics becomes important in the major aspect of lift. This law states that for every Action, there is an opposite and equal force. Relating to aviation, this involves the magnitude of pressure the wing of an airplane exerts and the equal and opposite reaction the air in the atmosphere exerts . The action or reaction encompasses the amount of possible pressure the wing gets when air is passed on it and also the pressure it gets when it is pushed back. The wing is technically designed to achieve its role. This wing has a flat bottom and a perfect curve which is seen on the top. The top provides the area of the low pressure which is responsible for the lift.
Weight of the plane is the field force. This is capable of pulling the plane to the center of the earth. This field force is supposed to be suppressed and countered by the lift, which is the opposing force. This is crucial for the balancing of the plane on air. The balancing should be right from the tail to the very tip of the plane.
Thrust becomes the second most significant principle after the lift. Thrust is instrumental in moving the plane forward. This is a situation that is made possible when the engine provides power. Thrust is achieved through a propeller or jet engines. Thrust is important because it makes the plane move forth and also allow the air pass over its wing. This enables the plane to balance on air. Air is required to move at a relatively high speed over the wings in order to achieve the lift.
This is the aerodynamic force which enables the plane to fly. It is crucial because it controls the plane by decelerating its speed. The aircraft is designed to specifically take into consideration the laws regarding aerodynamics. Also like lift, drag uses similar principles, which is the mechanical force that is generated when a solid body is in contact with the solid or gas
Hopefully we have explained the forces at work in order for the planes to fly harmoniously;
So What Have We Learnt?
- Perfect coordination is essential for the aircraft to fly high without any mishaps whilst in the air.
- The lift for instance is created when substantial amount of air is passed and moved around the wings of the plane.
- The shape of the plane is designed in way to fly without making perilous friction with the air.
- The lift of the airplane largely depend on the 3rd law of newton – Every action, is coupled with an opposite and equal force.
- The air that moves under the plane, it is equally deflected downwards with an equal measure and force. This in in turn lifts the plane in the upward direction.
- Thrust also is crucial in moving the plane forward, and also regulating the speed of the plane.

Understanding Centrifugal Force
The science of how things work indicates so much about our daily life and the instruments as well as machines we use. It is therefore important for many to understand the force that is applied in daily life especially when driving a car. A racing car going round turns offers the perfect example of centrifugal force and how it aquatically determines, the speed, the turns and the control of the car.
This is a force that helps in moving the car drawing a rotating body away from its center of rotation. The car’s movement is determined by the inertia. According to Newtonian mechanics, centrifugal force refers to the two distinct concepts that is fictitious force which is normally observed in non-inertial reference form and the equal and opposite reaction to centripetal force. This law applies perfectly to a racing car as it turns round a track. The drivers’ body inertia causes him to feel pushed back as the car starts to move. When the car peaks its momentum and now turning on circular motions on top sped, the driver starts to experience some uncomfortable feelings as he feels being thrown away to the outside of the track.
Centrifugal law can be explained by stating that it causes an object to move to certain detraction but still its force can push aside due to the inertia. This means that the cars’ direction automatically changes if the car turns. The Newtonian Law however states that a moving object will always continue moving in a straight line if the net force acted on it continues. For the car to continue moving on a circular track, force must be applies. This is what is known as the centripetal force is. This force normally points to the center of the circular path where the object in this case, the racing car is moved to. It is through this force that the driver feels like he is being pushed outside.
A curved track where the classic chrome cars moves on round motions always has some inclination to the horizontal because there exists an extra force to enhance its magnitude of centripetal force. In simple understanding, the direction of this force being reacted on is usually so normal to the track and its component that makes it horizontal component helps in serving as centripetal force while the vertical component simply offers balance to the weight of the car. This means that the banked curve combined with roughness of fast moving tires and track surface prevent the car from getting out of the track if the car is moving on a fast speed. .
