What is the lift coefficient of a Boeing 747?

0.52
A Boeing 747 is flying at an altitude of 12,192 meters and has a velocity of 265.5 m/s. The aircraft has a wing area of 510.97 m2. The coefficient of lift is 0.52 and the density is of air at 12,192 meters is approximately 0.30267 kg/m3. The weight of the 747 is 2,833,500 N (637,000 pounds).

What is the average cruising altitude for a Boeing 737?

around 24,000 feet
7 around 24,000 feet are average for the 737.

What is a good wing loading?

Wing loading for birds is generally between 1 to 20 kg/m2. Twing lohe maximum possible wing load before a bird is unable to fly is about 25 kg/m2. This is when the bird is too heavy for its wings (like the kiwi, which has tiny wings and a large body mass).

What is wing planform area?

In aerodynamics, the surface area of a wing is calculated by looking at the wing from a top-down view and measuring the area of the wing. This surface area is also known as the planform area. The planform area is an important value when calculating the performance of an airplane.

How do you calculate coefficient of lift?

To calculate coefficient of lift:

1. Multiply fluid pressure by velocity squared and divide the product by 2.
2. Multiply the surface area with the preceding product.
3. Divide the lift force by the product.

How long does it take for a plane to reach 10 000 feet?

On average, how long does it take for a plane to reach an altitude of 10,000 ft? My general aviation aircraft climbs at slightly less than 1,000 FPM so, if departing a sea level airport it would take me about ten and a half minutes to reach 10,000 feet.

What is wing loading ratio?

In aerodynamics, wing loading is the total mass of an aircraft or flying animal divided by the area of its wing. The stalling speed of an aircraft in straight, level flight is partly determined by its wing loading. This increased wing loading also increases takeoff and landing distances.

How do you calculate wing lift area?

Your wing area is the length of your wing times the width of your wing. If you are measuring a biplane, with two wings, measure both. This number will be called A, for area. Use the density of air.

How much lift does an airliner wing produce?

An airliner wing may produce a pound of lift per square inch in level flight. That doesn’t seem like much, but over the entire surface of the wings these pounds-per-square-inch add up. The wings of a Boeing 747 have a surface area of about 510 square meters (5,500 square feet) and can produce as much as 390 tons (850,000 pounds) of lift.

How do you calculate wing loading on a plane?

How to Calculate Wing Loading. In this example, we will use an aircraft weighing 5-1/2 lbs (5 lbs 8 oz.) with 600 square inches of wing area. Calculating the wing loading requires that the wing area be converted to square feet (ft 2) and pounds to ounces. 1) Convert the area to square feet. There are 144 (12 x 12) square inches in a square foot.

What is the formula to calculate the lift of an airplane?

L = (1/2) d v 2 s CL L = Lift, which must equal the airplane’s weight in pounds d = density of the air. This will change due to altitude. v = velocity of an aircraft expressed in feet per second s = the wing area of an aircraft in square feet CL = Coefficient of lift , which is determined by the type of airfoil and angle of attack.

What factors affect lift in airplanes?

Factors Affecting Lift. What Factors Affect Lift? The size and shape of the wing, the angle at which it meets the oncoming air, the speed at which it moves through the air, even the density of the air, all affect the amount of lift a wing creates. Let’s begin with the shape of a wing intended for subsonic flight.
