Aerodynamics and wind energy are two interconnected topics which are rapidly gaining prominence as sources of renewable energy for both consumers and large scale producers. Aerodynamics is the study of forces and the resulting motion of objects through air or other gases. Wind energy utilizes the aerodynamic forces created by the motion of the air to generate mechanical or electrical power. In order for wind to be harnessed efficiently, the interaction of air on the turbine needs to be understood. Wind turbines are usually classified according to their aerodynamic design, such as a two-blade vertical axis or a three-blade horizontal axis turbine. Through the use of specialized designs and aerodynamic principles, wind energy harnessing is becoming increasingly successful and efficient.
Wind turbines are particularly effective due to their ability to reduce air pressure in the blades resulting in maximum force for maximum power output. Additionally, certain design elements such as airfoils and aerofoils are used to improve air flow and stability in the blades. By understanding the aerodynamic forces involved in air flow and the resultant impacts such as lift and drag, wind turbines and other energy sources can be designed for optimal energy output. By understanding the science surrounding aerodynamics, wind energy can become an increasingly viable source of renewable energy for many consumers. In the following section, the key takeaways from this topic will be discussed further.

What Is Aerodynamics and Wind Energy?
Aerodynamics is the study of motion caused by air moving over an object, often manifactured for propulsion, such as an airplane wing or a wind turbine. Wind energy is the name given to the energy generated from air moving across a rotation turbine.
Aerodynamics Getting Started
Aerodynamics is studied in a wide variety of fields, ranging from aircraft to automobile engines. At its core it is an interdisciplinary subject that combines the effects of pressure, friction, lift, and drag as a method of understanding a variety of forces. As a study it involves a variety of techniques to measure and pressure, and simple shapes such as cylinders, disks, and wings to act as control surfaces.
Wind Energy
Wind energy, or the power produced by moving air, is a certain type of kinetic energy generated by wind turbines, which are composed of a number of steel blades spinning on an axle. The turning motion of the blades causes wind energy to be converted into an electrical current, and this current is then stored and used for transmission through power lines. Wind energy is an important renewable resource and can be used to power nearly any kind of electrical device, from small appliances to larger scale industrial operations.
Types of Turbines and Benefits of Wind Energy
Wind turbines come in two main types: horizontal axis and vertical axis. Horizontal axis turbines have their blades mounted on an axle which is perpendicular to the ground, while vertical axis turbines have their blades mounted on an axle which is parallel to the ground. Vertical axis turbines are more efficient in turbulent conditions than horizontal ones, and can operate at lower wind speeds, making them more suitable for residential areas.
Using wind energy for your home or business has a number of benefits, including the cost savings associated with being able to produce your own energy. Additionally, wind power is a renewable source of energy, meaning no emissions are released when it is being generated. The majority of turbines used to generate wind energy are also relatively quiet, making their surroundings livable.
Tips for Getting the Most Out of Your Wind Turbines
1. Choose the Right Type: Ensure you select the type of wind turbine that can handle the type of wind in your area.
2. Maxmize Efficiency: To maximize efficiency, it’s essential to maintain your wind turbine weekly. Check for loose connections and damaged blades and have them replaced as necessary.
3. Check the Regulations: Before installing wind turbines, check your local government regulations to make sure you can legally install them.
4. Invest in Quality: High quality wind turbines can last for decades, so be sure to invest in quality turbines when possible.
5. Create a Support Structure: Be sure to create a strong support structure for your turbines since they can be heavy and can be affected by strong winds.
What is Aerodynamics?
Aerodynamics is the study of how air flows around and within solid objects. This is the principle behind the motion of airplanes, helicopters, and other objects that are able to stay in the air. The motion of air near the surface of the object creates a region of low pressure, which creates lift and helps the object stay in the air.
What is Wind Energy?
Wind energy is the production of electricity from the winds that blow across the surface of the Earth. Wind turbines are used to convert the kinetic energy of the wind into electricity. Wind turbines are typically located in areas where the winds are strong and consistent.
How Does Wind Energy Work?
Wind energy works by capturing the kinetic energy of the wind and converting it into electrical energy. The energy is created as wind passes through the blades of a wind turbine, which rotate around a horizontal or vertical axis. The rotational motion of the blades is converted to electrical energy by a generator inside the wind turbine.
