Concept of Lift and Drag!

Concept of Lift and Drag! George Cayley's theory. The most crucial force responsible for the aircraft to fly is the lift force, so it’s necessary to know the concept of how lift is generated important. To understand lift, imagine a cardboard. And let’s consider two situations: You are holding cardboard perfectly horizontal against the wind. You are holding cardboard tilted up making some angle with the horizontal against the wind. CASE 1: You are holding cardboard perfectly horizontal.             In this case you can see that the cardboard exerts a force on your hand (negligible) but do not exert any force in vertical direction and stays as it is. This force that pushes the cardboard back is due to cardboard opposing the flow of air. This force is known as ‘Drag’ CASE2: You are holding cardboard tilted up making some angle with the horizontal against the wind.             In this case as soon as you hold the cardboard at some angle against the wind you see that

How Airplanes Fly?

How do Airplanes Fly? Every aviation enthusiast’s first question probably was how airplanes fly? So in this blog I’m writing about the physics and science behind how airplanes fly. First, let’s see forces that can make the airplane stay in air. 1.       We need a force that will pull the aircraft so it moves forward. Let’s call this force ‘ Thrust’ 2.       We need a force that will balance the weight of aircraft so that it takes off from ground, stays in air and don’t fall back to earth surface. Let’s call this force ‘ Lift’ Thrust, as we know is provided by the engines, but how is lift generated? Yes, the answer is WINGS. But how do wings generate lift? Fig 1: A simple wing of airplane If we look at the wing as shown in Fig 1, when looked from a side the profile looks as the figure 2. This is a special geometry called ‘ airfoil ’ Fig 2: Cross section of wing: Airfoil So, what’s so special about the airfoil? The airfoil as seen in Fig 2 has the length at l

Fundamental Forces of Flight.

Fundamental Forces of Flight. Primarily 4 forces act on an aircraft: Weight Lift Thrust Drag   Fig 1: Fundamental forces of flight WEIGHT: Weight of the aircraft is the force that acts at the center of gravity in downward direction (in the direction of acceleration due to gravity ). The direction is fixed and doesn’t change during the course of flight, as acceleration due to gravity always point towards the center of earth. LIFT: To counter the weight and allow the aircraft to be airborne and not to fall back to earth surface, aircraft must generate force opposite to weight and which is equal to or greater than weight. The lift force is generated by the wings when the airflow causes pressure difference in the upper and lower part of wing i.e. high pressure at lower part of wing and low pressure at upper part. This pressure difference generates lift. Lift acts perpendicular to the direction of motion of aircraft. THRUST: Thrust is the force that propels (or pulls)
