Abstract - Wind energy is an emission-less and sustainable
way of producing electricity. Conventionally wind turbines are classified as onshore or offshore wind turbines but there is another unconventional wind turbine known as Airborne Wind Energy systems or AWEs. The AWEs are further Classified on the basis of where the electricity is generated as Ground-Gen and Fly-Gen. This project involves the design and analysis of the Airborne Wind Energy system (AWEs) which can also be referred to as Buoyant Air Turbine (BAT). The Fly-Gen AWEs differ from a traditional wind turbine in the following way, instead of having a solid upright structure upon which the turbine is mounted the fly-gen AWEs will be floating in the air and will be anchored to the ground by the means of cables. The Buoyant Air Turbine consists of the following components (i) Motor-generator (ii) Turbine (iii) Gearbox (iv) Transmission Cables (v) Balloon. CFD analysis is done for the model designed in CREO, with the help ANSYS by giving input of thermophysical properties of the fluid and faces of inlet and outlet to the model. Lift, Drag and viscous force are obtained for wind velocities 3,4,5,6m/s and discussed.
Renewable energy plants have expanded and spread significantly in this environment in recent decades. Wind generators are the most popular form of intermittent renewable energy harvester, with 369 GW of total installed power as of the end of 2014. With an increase of 51.4 GW in 2014, wind capacity, or total installed power, is on the rise. Due to the saturation of in-land windy places appropriate for installations, such growth may slow in the future. As a result, contemporary research efforts are intended to maximize the capacity of power per unit of land area. This is in line with a global industry trend toward single wind turbines with higher nominal power (up to 5 MW), longer blades (to increase swept area), and taller turbine axes (to reach stronger winds at higher altitudes).
1.1 Principle Airborne Wind Energy is a wind energy system that uses a tether to connect flying blades or wings to the ground. There are two fundamental concepts for converting wind energy into electricity:
Key Words: Airborne Wind Energy Systems, Buoyant Wind Turbine, Fly-Gen, Ansys, CERO, Drag Force, Lift Force.
1. INTRODUCTION
Either by using small propeller turbines with generators positioned on the flying wing (first image) or by having the wing or kite pull on the tether and the tether unwind from a drum on the ground, which drives the generator (second picture). This type of ground production requires reeling in the cable (third image), which causes a churning or tumbling action.
Variations in the amount and kind of energy available to meet human needs for sustenance and labor are intimately tied to the advancement of societies, particularly in their ability to sustain greater populations. Poverty is associated with a lack of access to energy. Water, food, healthcare, education, work, and communication are all essential services that require energy, particularly electricity. So far, the bulk of energy utilized by our society has come from fossil and nuclear fuels, which are today facing substantial supply security, economic affordability, environmental sustainability, and catastrophic dangers. Major countries are establishing energy policies aimed at increasing the deployment of renewable energy technology to solve these issues.
1.2 Airborne Wind Energy The acronym AWE (Airborne Wind Energy) is commonly used in the literature to refer to both the high-altitude wind energy resource and the technology industry. Meteorologists, climatologists, and environmental scientists have been studying high-altitude winds for decades, despite the fact that many problems remain unanswered. Archer and Caldeira provided the first study aimed at analyzing AWE's potential as a renewable energy resource. Their report describes a study that examines the vast global availability of wind kinetic energy at altitudes ranging from 0.5 to 12 kilometers above the earth, presenting unambiguous

The United Nations member nations have been committed to a significant decrease in greenhouse gas emissions below 1990 levels since 1992, in order to avoid the most severe effects of climate change.
