how to create a lifting line theory code in javascript

To create a lifting line theory code in JavaScript, you can follow these steps:

  1. Define the necessary constants and parameters for your lifting line theory calculations. These may include the wing span, chord length, airfoil data, and other relevant values.

  2. Create a function to calculate the lift distribution along the span of the wing using the lifting line theory equations. You will need to iterate over different spanwise locations to determine the lift coefficient at each location.

  3. Implement the lift distribution function by discretizing the wing span into a series of segments. For each segment, calculate the spanwise lift coefficient based on the local angle of attack and airfoil characteristics.

  4. Integrate the local lift coefficients over the wing span to obtain the total lift coefficient of the wing.

Here is a basic example of how you could start implementing a lifting line theory code in JavaScript:

index.tsx
// Constants and parameters
const wingSpan = 10; // Wing span in meters
const chordLength = 1; // Chord length in meters
// ... other parameters

// Function to calculate lift coefficient at a given spanwise location
function calculateLiftCoefficient(spanwiseLocation) {
  // Implement your lift coefficient calculation here, using lift line theory equations
  // Return the lift coefficient at the specified spanwise location
  // For example:
  const localAngleOfAttack = ...; // Calculate the local angle of attack at the given spanwise location
  const liftCoefficient = ...; // Calculate the lift coefficient based on the airfoil characteristics and local angle of attack
  return liftCoefficient;
}

// Function to calculate the lift distribution along the span of the wing
function calculateLiftDistribution() {
  const numSegments = 100; // Number of segments to discretize the wing span
  const segmentLength = wingSpan / numSegments;
  let totalLiftCoefficient = 0;

  for (let i = 0; i < numSegments; i++) {
    const spanwiseLocation = i * segmentLength;
    const liftCoefficient = calculateLiftCoefficient(spanwiseLocation);
    totalLiftCoefficient += liftCoefficient;
  }

  // Display the total lift coefficient
  console.log('Total lift coefficient:', totalLiftCoefficient);
}

// Call the function to calculate the lift distribution
calculateLiftDistribution();

Please note that this is just a starting point and may require further modifications and refinements for a complete and accurate lifting line theory implementation.
