Lift to Drag Ratio Formula
The following formula is used to calculate the Lift to Drag Ratio.
LDR = L / D
- Where LDR is the Lift to Drag Ratio
- L is the total lift force (N)
- D is the total drag force (N)
How to Calculate Lift to Drag Ratio?
The following example problems outline how to calculate Lift to Drag Ratio.
Example Problem #1:
- First, determine the total lift force (N).
- The total lift force (N) is given as: 150.
- Next, determine the total drag force (N).
- The total drag force (N) is provided as: 200.
- Finally, calculate the Lift to Drag Ratio using the equation above:
LDR = L / D
The values given above are inserted into the equation below and the solution is calculated:
LDR = 150 / 200 = .75
Example Problem #2:
For this problem, the variables required are provided below:
total lift force (N) = 200
total drag force (N) = 30
Test your knowledge using the equation and check your answer with the calculator above.
LDR = L / D = ?
