what forces are necessary for an airplane for an airplane to take flight?

Question

when analyzing the forces that make flight possible, what does each force represent?

Answer 1

Flight is the resultant of the inequilibrium of four forces namely Drag, weight, lift and thrust.

Drag is predominantly a frictional force acting against the direction of flight.
Thrust is the force that propels the aircraft forward, it acts in the opposito direction of the drag
Weight shouldbe obvious...
Lift is the upward force produced mainly by the wings, acting opposite to weight.

For flight, lift needs to be equal to weight and thrust should equal drag. Any inbalance would tend to move the aircraft towards the resultant. For example when thrust is greater than drag, the aircraft accelerates and when the lift is greater than the weight, the aircraft climbs.

Answer 2

Four forces are acting during level flight. Those forces are: lift, weight, thrust an drag. Lift is the upward force created by the effect of airflow as it passes over and under the wing. Weight represents the opposing force to lift and it is caused by gravity. Thrust is the forward force which pushes the airplane forward. And drag is the force that opposes thrust which is a backward force that limits the speed of an airplane. When in unaccelerated flight the forces are equal. When stopped on ground weight is far greater than lift and thrust and drag are equal. When accelerating and taking off lift is greater than weight and thrust is greater than drag.

Answer 3

The following defines these forces in relation to
straight-and-level, unaccelerated flight.
Thrust is the forward force produced by the powerplant/
propeller. It opposes or overcomes the force of
drag. As a general rule, it is said to act parallel to the
longitudinal axis. However, this is not always the case

Drag is a rearward, retarding force, and is caused by
disruption of airflow by the wing, fuselage, and other
protruding objects. Drag opposes thrust, and acts rearward
parallel to the relative wind.
Weight is the combined load of the airplane itself, the
crew, the fuel, and the cargo or baggage. Weight pulls
the airplane downward because of the force of gravity.
It opposes lift, and acts vertically downward through
the airplane’s center of gravity.
Lift opposes the downward force of weight, is produced
by the dynamic effect of the air acting on the
wing, and acts perpendicular to the flightpath through
the wing’s center of lift.

Answer 4

When aircraft starts rolling, Wind begins to flow from the leading edge to the trailing edge of the wing.

Wind splits into 2 lines traveling onto the upper and lower surface of the wing.

These 2 lines of wind will reach at the trailing edge of the wing at one time.

Normally the upper surface of the wing is MORE CURVE than the lower surface of the wing. This mean wind speed traveling at the upper surface is higher than wind speed traveling at the bottom surface, because they reach the trailing edge at the same time.

Greater speed, Less pressure. Lower speed , More pressure

So, the pressure at the lower surface is MORE than the pressure at the upper surface. This is LIFT FORCE bringing the aircraft go up into the air.

Answer 5

A vacuum, believe it or not. As the airplane's speed increases, the wing's shape forces air up and over the plane's wings, creating a gap, and giving the air little or no time to fill it in. This creates the vacuum, or less pressure, which essentially "sucks" the plane up into the air...

Answer 6

There are four forces that have to be in balance for an aircraft to fly. They are; lift, gravity thrust and drag. When Lift over comes Gravity and Thrust over comes Drag you should be flying. When thrust over comes drag you go faster and fast makes air flow over the wings, which causes lift to over come gravity. This is the short answer.

Answer 7

What is take flight? You ment take off i guess...Here is why...for every applied force there will be a force in oposite direction... as in plane...1. applying full power using throttle is one force... and which pushes airplane in the other direction is the second force...

Answer 8

Air Speed,Resistence,and lift.

Answer 9

lift
