1. What is a Sloped Armor Thickness Calculator?

Definition: This calculator determines the effective thickness of sloped armor based on its actual thickness and angle of slope.

Purpose: It helps military engineers, vehicle designers, and armor analysts evaluate the protective qualities of angled armor.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( t_{eff} \) — Effective thickness (mm)
• \( t \) — Actual armor thickness (mm)
• \( \theta \) — Angle of slope (degrees from vertical)

Explanation: The actual thickness is divided by the cosine of the slope angle to calculate the equivalent thickness of vertical armor.

3. Importance of Effective Thickness Calculation

Details: Sloped armor provides better protection than flat armor of the same thickness by increasing the effective thickness that projectiles must penetrate.

4. Using the Calculator

Tips: Enter the actual armor thickness in mm and the angle of slope in degrees (0-89.99). All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Why does sloped armor provide better protection?
A: Sloping increases the effective thickness and can cause projectiles to ricochet, reducing penetration capability.

Q2: What's the maximum effective angle?
A: The formula becomes invalid at 90° (cos(90°)=0). Practical maximum is typically around 70-80° before ricochet effects dominate.

Q3: Does this account for projectile normalization?
A: No, this is the basic geometric calculation. Advanced models include normalization effects.

Q4: How does armor material affect this calculation?
A: The formula is material-agnostic but different materials may have varying performance at different angles.

Q5: What units should I use?
A: The calculator uses millimeters for thickness, but any consistent units will work proportionally.
