LO16: Describe how turbine performance is influenced by the blade length, strength of materials and siting requirements

Question 1

Describe 2 ways in which the performance of a turbine can be influenced by each of the following factors:

Blade Length
Strength of materials

Answer 1

Blade length: 1: Larger blades generate more power than short bladed due to larger swept area.
2. Longer blades may need stronger wind speeds to generate power.

Strength of Materials: 1. Lightweight blade materials may be too weak and may brake.

2. Stronger, heavier blades need stronger wind speeds to generate power
