## Which NACA airfoil produces the most lift?

NACA 4412

Table of Contents

There is no single airfoil that will always create more lift than another airfoil. The amount of lift that an airfoil creates has to do with the angle of attack, speed, and other flight conditions. Different airfoils work well in different conditions. A very common NACA airfoil is the NACA 4412.

### How is NACA airfoil calculated?

Calculating the Thickness of a NACA 4-Digit (Modified)Airfoil

- y = one half the maximum thickness when x/c = m, the specified location of maximum thickness (as fraction of chord).
- The leading edge radius = 1.1019/36.0*((t/c)*leIndex))2 [ see p.

**Which NACA airfoil is best?**

NACA 4412 is good to use. It has low drag and increased lift forces at relatively low wind speeds .

**What does NACA 4412 mean?**

The NACA 4412 is a four digit airfoil. The first digit expresses the camber in percent chord, the second digit gives the location of the maximum camber point in tenths of chord, and the last two digits gives the thickness in percent chord.

## Which airfoil has the highest lift?

From the graph plotted in Fig. 4, it has been found that both Selig S1223 and FX 74-CL5- 140 airfoils have the highest lift coefficient among the studied airfoils, and they also possess moderate-stall characteristics.

### What aircraft uses NACA 4412?

The NACA 4412 has been used in sports plane. The example includes AAI-AA2 mamba aircraft, aeronca series aircraft like aeronca 65-tac defender, aeronca 11ac chief etc while the S1223 is an airfoil used in heavy lift cargo planes [2].

**How do you calculate coefficient of lift?**

The lift coefficient is defined as: CL = L/qS , where L is the lift force, S the area of the wing and q = (rU2/2) is the dynamic pressure with r the air density and U the airspeed. Similarly, the drag coefficient is written as: CD = D/qS , where D is the drag force and the other symbols have the same meaning.

**What is the most common NACA airfoil?**

Abstract: NACA 0015 and NACA 4415 aerofoil are most common four digits and broadly used aerodynamic shape. Both of the shapes are extensively used for various kind of applications including turbine blade, aircraft wing and so on. NACA 0015 is symmetrical and NACA 4415 is unsymmetrical in shape.

## What is the chord length of NACA 4412?

The freestream conditions listed in this reference are: velocity = 27.13 m/s and kinematic viscosity (nu) = 0.1605 cm2/s. The airfoil chord length was 90.12 cm.

### How much lift do flaps add?

Flaps can more than double the lift available from a plain airfoil, and thereby reduce landing speed by as much as 30 percent.

**Do flaps increase coefficient of lift?**

A leading edge flap increases the curvature of the top of the airfoil. This considerably increases the lift coefficient. A movable slat (slotted leading edge flap) increases the lift through a combination of increased wing area and increased camber and through the influence of the flow with the aid of the slat.

**What is the NACA 0012 airfoil used for?**

NACA 0012 airfoil is chosen to model and simulate processes of computational fluid dynamics. Analyzes to obtain velocity and pressure distribution on the wing surface were performed using ANSYS Fluent software. Also, the drag and lift coefficients were calculated according to variable relative velocities.

## Which flap gives the best lift coefficient?

Fowler. The Fowler flap provides the greatest amount of lift and the least amount of drag.

### How do you calculate airfoil lift?

Yes, Lift force acting on an airfoil is calculated as L=1/2 CL ρ V∞2 , where ρ is the air density and V∞ the free upstream flow velocity.

**Are NACA airfoils still used?**

NACA airfoils are still used on modern aircraft.

**Do flaps increase lift coefficient?**

A leading edge flap increases the curvature of the top of the airfoil. This considerably increases the lift coefficient.

## What does NACA 2412 airfoil mean?

NACA airfoils map a four digit code to an airfoil shape. For example, a ‘2412’ airfoil is parsed to mean: The leading ‘2’ indicates maximum camber is 2% of chord length. The ‘4’ indicates maximum camber is at 40% of the chord length. The ’12’ indicates maximum thickness is 12% of the chord length.

### What’s the formula for lift?

The lift equation states that lift L is equal to the lift coefficient Cl times the density r times half of the velocity V squared times the wing area A. For given air conditions, shape, and inclination of the object, we have to determine a value for Cl to determine the lift.

**What is the formula to calculate lift?**

The lift formula explained – YouTube

**What airfoil does a Boeing 747 use?**

The supercritical airfoils were not available when the Boeing 737 was first designed. However, the 737 NG airfoil incorporates elements of supercritical design,as does the Boeing 747-8 airfoil. The supercritical airfoils reduce the fuel required, as they allow the aircraft to cruise at higher speeds with lesser drag.

## What does NACA 0012 mean?

NACA 0012 mean that there is no camber i.e. zero camber is present, and it has the maximum thickness of the airfoil at 12% of the chord from the leading edge.

### How do you find the coefficient of lift of an aerofoil?

The lift coefficient Cl is equal to the lift L divided by the quantity: density r times half the velocity V squared times the wing area A. The lift coefficient then expresses the ratio of the lift force to the force produced by the dynamic pressure times the area.

**What airfoil does 737 use?**

Boeing 737’s midwing section is a modified version of NACA 22112 airfoil with maximum thickness of 12% at 29.5% chord and maximum chord of 0.8% at 9.6% chord, which is depicted by Figure 2. …

**Which aircraft uses NACA 2412?**

11: Airfoil NACA 2412 used for the Cessna 172S [127] A.

## Why is the NACA 0012 airfoil used?
