Question

What is the percentage of increment in lift produced by two main wings when compared to monoplane of similar aircraft?

• A. 10%
• B. 20%
• C. 30%
• D. 50%

Hint:

More lifting surfaces increase lift but also potentially increase drag and weight — careful aerodynamic balancing is needed.

Answer 1

The Correct Option is B

In aerospace engineering, the lift produced by an aircraft's wings is a critical factor for efficient flight. When comparing the lift of a biplane (two main wings) to a monoplane (one main wing), the aerodynamic design plays a pivotal role.

Considering the aerodynamic advantages, a biplane configuration often increases the overall lift due to additional lift surfaces, leading to an increase in the wing surface area and improved lift distribution. The increase in lift for a biplane configuration typically results in a percentage increase compared to a monoplane.

In this context, the correct percentage increment in lift produced by two main wings (biplane) compared to a monoplane of similar design is generally around 20%. This enhancement is primarily due to the increased wing area and better lift characteristics in biplane designs under similar conditions, which are well reported in aerospace studies and empirical findings.
