Lift is calculated using the following equation:
L = 1/2 p V2ACL
Where:
L = Lift which is typically the weight of the aircraft
p = air density (altitude and temperature effect this variable)
V = velocity of the aircraft (this is the airspeed)
A = wing area (including the section of the wing that is inside the fuselage)
CL = is specific to each aircraft. This coefficient is calculated in a wind tunnel and is typically provided as a graph relative to the angle of attack.
What else can I help you with?
How can a wings lift be increased?
Lift can be increased by curving the wing downward. Most aircraft have 'flaps' at the rear inner edge of the wing to achieve this. Some aircraft even have 'slats' at the front of the wing to increase lift even more. - If you google 'aircraft slats', you will see a great picture of slats and flaps on an Airbus A310
Who first invented lift?
If we are talking about aircraft lift, it was likely discovered, not invented. You can discover Gold, you don't invent it...
Can an aircraft overcome lift without wings or propellers?
No, that is not possible except with rotors. (which I would include among propellers)
What is the difference between angle of attack and positive angle of attack?
Angle of attack may be negative or positive - it's simply the angle between the wing chord line and the oncoming airflow. If it's positive then the aircraft will benefit from the lift that is provided, if it's negative then there is no lift (but there's still drag). This is a potentially dangerous situation, unless you wish your aircraft to descend.
What is induced lift?
Induced lift is the lift generated by a wing or airfoil as a result of the pressure difference between the upper and lower surfaces during flight. This phenomenon occurs due to the creation of vortices at the wingtips, which alters airflow and contributes to lift. Essentially, induced lift is a byproduct of the wing's angle of attack and its interaction with the surrounding air. It is particularly significant at lower speeds and higher angles of attack, where it becomes a critical factor in aircraft performance and stability.
What is the lift drag thrust weight formula used in aviation to calculate the forces acting on an aircraft during flight?
The lift, drag, thrust, and weight formula used in aviation is a way to calculate the forces acting on an aircraft during flight. It states that lift must equal weight and thrust must equal drag for the aircraft to maintain level flight.
What does the weight of the airplane have to do with the lift of it?
The weight of an aircraft counteracts the lift produced by an aircraft. The heavier an aircraft weighs the greater the lift needed to get off the ground.
How do wingless aircraft produce lift?
The only 'wingless aircraft' are helicopters. These produce lift lift from the rotor blades, which are in fact, long narrow wings.
What is the lift force in an aircraft?
The lift force is the force acting against the aircraft's weight. For straight and level flight, lift acts in the upward vertical direction and the weight of the aircraft acts in the downward vertical direction. For level flight, lift = weight.
Is lift an unbalanced force?
Yes, lift is an unbalanced force. It acts in opposition to the weight of an aircraft, allowing it to rise or remain in the air. When the lift generated by the wings exceeds the gravitational force acting on the aircraft, the result is an upward acceleration. Conversely, if lift is less than weight, the aircraft will descend.
What is a rotary aircraft?
A rotory aircraft is essentially a helicopter or a type of aircraft that relies on the movement of its wing to produce lift.
If an aircraft is flying horizontally then its weight must be balanced by what force?
Lift balances weight. Thrust balances drag.
What is the amount of lift if you are 25000 feet in the are?
The amount of lift generated by an aircraft at 25,000 feet depends on several factors, including the aircraft's speed, wing design, and air density. At that altitude, the air density is lower than at sea level, which can reduce lift. However, aircraft are designed to maintain sufficient lift by flying at higher speeds or with larger wing surfaces. To calculate precise lift, one would typically use the lift equation: ( L = \frac{1}{2} \times \rho \times V^2 \times S \times C_L ), where ( L ) is lift, ( \rho ) is air density, ( V ) is velocity, ( S ) is wing area, and ( C_L ) is the lift coefficient.
What is aircraft propeller and what function does it do to the aircraft?
An aircraft propeller is what gives the aircraft power to move it forward (or backward, depending on it's pitch). This enables the aircraft to acquire lift and gain altitude. Propellers are found on some fixed-wing aircraft and autogyros. On helicopters, the blades that lift it and stabilize it are called rotors.
Why is maximizing the ratio of lift to drag forces desirable?
Maximizing the lift-to-drag ratio is desirable because it allows an aircraft to generate more lift for a given amount of drag, resulting in improved fuel efficiency and range. A higher lift-to-drag ratio also means the aircraft can fly at higher altitudes and speeds, which can be beneficial for performance and overall aircraft capabilities.
What is the term for the upward force on the wings of an aircraft?
Lift.
What part of aircraft makes flight to take off?
The engines provide forward thrust, allowing the wings to generate lift. It is the lift that allows the aircraft to take off.
