AVIATION & AERONAUTIC CALCULATOR
Thickness Ratio Drag
A precise tool.
What is the Thickness Ratio Drag & How does it work?
The thickness-to-chord ratio of an airfoil significantly affects its aerodynamic performance, particularly at supersonic speeds. A higher thickness-to-chord ratio can lead to increased drag divergence Mach number, which is the Mach number at which the drag coefficient starts to increase rapidly.
M_{dd} = frac{1}{sqrt{2(1 + left(frac{t}{c}right)^2)}}
Mdd = Drag Divergence Mach Number
t/c = Thickness-to-Chord Ratio
t/c = Thickness-to-Chord Ratio
Understanding and optimizing this ratio is crucial for designing efficient supersonic aircraft. The formula above helps in predicting the drag divergence Mach number based on the airfoil’s thickness-to-chord ratio.

Frequently Asked Questions
What is the formula for calculating the Drag Divergence Mach Number?
The formula is M_{dd} = frac{1}{sqrt{2(1 + (frac{t}{c})^2)}} where t/c is the thickness-to-chord ratio.
How does a higher thickness-to-chord ratio affect an airfoil’s performance?
A higher thickness-to-chord ratio can lead to increased drag divergence Mach number, causing the drag coefficient to rise rapidly at supersonic speeds.
Why is understanding the Drag Divergence Mach Number important in aviation?
Understanding it helps in designing efficient airfoils that minimize drag, especially at high speeds.
Can you explain what the thickness-to-chord ratio represents?
The thickness-to-chord ratio is the ratio of the maximum thickness of an airfoil to its chord length, a key factor in aerodynamic performance.
What does the Drag Divergence Mach Number indicate about an aircraft’s design?
It indicates the Mach number at which the drag coefficient starts to increase rapidly, helping designers optimize for efficiency and speed.
How do changes in thickness-to-chord ratio affect the Drag Divergence Mach Number?
Changes in the thickness-to-chord ratio directly impact the Drag Divergence Mach Number, influencing an aircraft’s aerodynamic behavior at supersonic speeds.
