# What is the lift coefficient of a Boeing 747?

## 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 ARe the coefficients of drag and lift?

The lift to drag ratio (L/D) is the amount of lift generated by a wing or airfoil compared to its drag. The lift/drag ratio is used to express the relation between lift and drag and is determined by dividing the lift coefficient by the drag coefficient, CL/CD. A ratio of L/D indicates airfoil efficiency.

### What is the range of the A350 1000?

16,100 km
Airbus A350-1000/Range

How do you calculate drag and lift coefficient?

The induced drag coefficient is equal to the square of the lift coefficient (Cl) divided by the quantity: pi (3.14159) times the aspect ratio (Ar) times an efficiency factor (e). The aspect ratio is the square of the span divided by the wing area.

#### What is the maximum lift coefficient?

The angle at which maximum lift coefficient occurs is the stall angle of the airfoil, which is approximately 10 to 15 degrees on a typical airfoil.

What is the best lift to drag ratio?

This is especially of interest in the design and operation of high performance sailplanes, which can have glide ratios almost 60 to 1 (60 units of distance forward for each unit of descent) in the best cases, but with 30:1 being considered good performance for general recreational use.

## How does drag affect lift?

Drag becomes greater than thrust and the plane slows down. This reduces lift and the plane descends. Airplane wings are designed to take advantage of lift. They are shaped so that air has to travel farther over the top of the wing than underneath it.

Is A350 bigger than 777?

Capacity, range and fuel efficiency. Both aircraft offer immense seating and cargo capacity, but the 777X is the larger of the two.

### Why is A350 special?

The A350 has a unique wing design that enables it to achieve optimal aerodynamic efficiency, resulting in a light and fuel‑efficient aircraft, and one that’s nine decibels quieter than other planes – a big plus for passengers.

What is a good lift coefficient?

Lift Coefficient: Incidence The value of C L max is a very important airfoil characteristic because it determines the minimum speed at which an airplane can fly. A typical value for the type of airfoil section mentioned is about 1.5.

#### Which type of flap gives the highest coefficient of lift?

slotted flaps
The lift curve of plain and slotted flaps is elevated to higher lift coefficients compared to the lift curve without flaps, but without increasing the stall angle. On the contrary, the stall angle tends to be smaller.

How tall is the wing span of an Airbus A350?

Official Airbus merchandise. Let’s shop. A350 Family aircraft. A350-900. A350-1000. Metric. Imperial. Height 17.05 m 55 ft 11 in. Wing span 64.75 m 212 ft 5 in.

## How are drag and lift related to aircraft efficiency?

As lift and drag are functions of air speed, their relationships are major determinants of an aircraft’s design efficiency. Aircraft efficiency is augmented by maximizing lift-to-drag ratio, which is attained by minimizing parasitic drag and lift-generated induced drag, the two components of aerodynamic drag.

Why is the Airbus A350 900 so good for the environment?

Incorporating advances in flight controls, systems and wing design, the A350-900 is a truly state-of-the-art aircraft. These developments have a genuine impact in terms of safety, maintenance and efficiency, meaning that the aircraft reduces its fuel burn significantly – generating savings and reducing its environmental impact.

### What are the specs of an Airbus A320?

The Airbus A318 is the baby of the Airbus A320 family of airliners which consists of the A318, A319, A320 and A321. As you will see in our Airbus A320 Specs table below, the A320 family of aircraft is configured as a low wing monoplane sporting a cantilevered wing with a sweepback of 25 degrees.
