The formula to calculate the lift efficiency ratio is:
\[ \text{LER} = \frac{\text{C}_L}{\text{C}_D} \]
Where:
The lift efficiency ratio (LER) is a measure of the aerodynamic efficiency of an aircraft. It is defined as the ratio of the lift coefficient (CL) to the drag coefficient (CD). A higher LER indicates a more aerodynamically efficient aircraft, which can generate more lift for a given amount of drag. This ratio is crucial in the design and performance analysis of aircraft, as it directly impacts fuel efficiency, range, and overall performance.
Let's assume the following values:
Using the formula:
\[ \text{LER} = \frac{1.5}{0.3} = 5 \]
The Lift Efficiency Ratio is 5.
Let's assume the following values:
Using the formula:
\[ \text{LER} = \frac{2.0}{0.4} = 5 \]
The Lift Efficiency Ratio is 5.
