Abstract A 21 in horizontal axis wind turbine needed to be built, by researching wind turbine technologies, to determine the best design to lift weights by attaching a string to the hub of the turbine and wrapping it over a pulley to attach the weight, it can lift the weight while facing a fan. To succeed with this task an overall research needed to select the best design to it can lift weight faster. Several designs were discussed. Overall, 3D printing would be the more beneficial due to its accuracy. The wind turbine has met the required criteria of constructing. 1 Introduction For ENGR101, it is a requirement to do 2 projects throughout the course. Since the first project is done, so the work now is on the second project. Students had the choice to choose their project out of 3 options. The first option was to build a Horizontal Axis Wind Turbine, which was the option selected by the team after a deep thinking and discussion. The second option was to build a game based on friction. However, the third option gave the students the ability to show their creativity if they want to since it consists of building your own project. Moreover, many benefits were gained in the first project and more benefits were gained in the second project. Writing a summary every week on the progress of the project was a major benefit since it remind students to summarize the ideas of what they took during the week for each class they are taking. In addition, each member of the team now have a background on wind turbines and other alternative energy sources which will be helpful for engineering students. 1 2 Problem statement A horizontal axis wind turbine needed to lift some weight. This would require building the best and most efficient design, so it can hold and lift the maximum weight possible. There are some constraints that it must be freestanding and an overall height of 21 in. 3 Objective The objective of this project was to design and build a wind turbine whose height is 21 inches including the base and the blades. With no materials limitation, however, it can’t be premanufactured. Certain limitation included that the centerline must be 10 ½ in so it can face the center of the fan. There is another constraint that each blade must not exceed 10 in so it can meet the required 21 in wind turbine. Introduction The working of wind turbines takes place by changing the wind energy into turbine’s rotational K.E and afterward the electrical power that is then devoured by electrical machines. The littlest turbines are utilized for applications, for example, battery charging for assistant power for vessels or troops or to power movement cautioning signs. Marginally bigger turbines can be utilized for influencing commitments to a residential power to supply while offering unused power back to the utility provider by means of the electrical network. Varieties of expansive turbines, known as wind ranches/farms, are turning into an inexorably imperative wellspring of an irregular sustainable power source and are utilized by numerous nations as a feature of a procedure to decrease their dependence on petroleum products. Power Determination of the Wind Turbine The computation of the K.Erot created in wind turbine at its appraised speed of wind must be performed. This is the base speed of the wind at which a wind turbine creates its evaluated power. Design of blade is flat plate section. By using resistor 200 2 Ω, average efficiency to delta connection is 6.2 percent and wye connection is 3.7 percent. Actually, the efficiency of both are still small. There are many losses in this prototype. Those are losses at turbine, generator and at line. Variables which are used for power determination are given below: The most extreme hypothetical power yield of a turbine operating on wind is, along these lines, 16/27 times the motor power of the air going through the compelling circle region of the machine. (Hau, 2005, Grogg, 2005) In the event that the viable territory of the plate is A, and the wind speed v, the greatest hypothetical power yield P is: Likewise, at this most extreme breaking point, wind turbines can't work. Transformation frameworks of wind energy is a framework which means to change the dynamic vitality of the breeze into mechanical vitality to the turbine shaft and afterward adjusted again by the generator into electrical vitality. Wind dynamic vitality with mass "m" is moving with speed v has the condition (Patel, 1999): The execution of the HAWT model was likewise decided from the tip speed ratio. Tip speed proportion is the furthest side speed correlation of the rotor against the breeze speed. Condition tip speed proportion is: This is the final equation for available power measurement. Wind Turbine Design In HAWT, at the highest point of a pinnacle, there is principle rotor shaft and electrical generator and must be pointed into the wind. Little turbines are pointed by a straightforward wind vane, while expansive turbines, for the most part, utilize a wind sensor combined with a servomotor. Most have a gearbox, which transforms the moderate turn of the blades into a snappier revolution that is more reasonable to drive an electrical generator. 3 Wind turbines are particular size classes. The humblest having power age under 10 kW are used as a piece of farms, homes, and remote applications. (Xiao-ping et.al, 2012) For HAWTs, tower statures approximately a couple of times the length of the edge have been found to modify material costs of the zenith against better utilization of the all the more exorbitant dynamic portions. The layout specific for a wind turbine will contain a power twist and guaranteed openness. With the data from the wind resource assessment, it is possible to learn business practicality. In wind turbine, the commonly utilized materials are composites for the rotor blades, as they have a tendency to have a high firmness, high quality, high weariness protection, and low weight. (Dan & Mcweigh, 2016) Typical pitches utilized for these composites incorporate polyester and epoxy, while glass and carbon filaments have been utilized for the material for strengthening. (Watson et.al, 2016) Construction may utilize manual layup methods or composite tar infusion shaping. As the cost of glass filaments is just around one-tenth the cost of carbon fiber, glass fiber is as yet overwhelming. Concluding Remarks It is expected to build the effectiveness by building up a unique breeze turbines which is basic, compelling and minimal effort wind turbine. What's more, the utilizing of the speed-increment gearbox can expand generator rpm despite the fact that the gearbox can add to vibration. The cross breed amongst flat and vertical hub can build the productivity because of vertical pivot wind turbine can turn at littler scale speed instead of the level hub. Wind energy be easily utilized with the help of this prototype even in areas where there is not enough velocity of the wind. It can be used there with ease and household electricity demand can be fulfilled in low cost and quick way. 4

Abstract
Students needed to research and design a horizontal wind turbine which is 21 inches high.
They had to carry extensive research on the technology used in creating wind turbines so that
they develop a model that can lift some weight. The weight was to be raised by a string attached
to the turbine's hub and wrapped around a pulley where the weight is attached. The success of
this project depends on the research so that the turbine designed can lift maximum weight within
a short time. Students were involved in discussions whereby they analyzed various designs by
use of 3D prints. The 3D prints are beneficial because they enhance accuracy thus the design
criteria are met adequately.
Introduction
Engineering students are supposed to engage in two projects in ENGR 101. The first
project has been completed and now the task lies in achieving the second one. Students have
three options from which they chose which plan is well suited for them. Option one required the
development of a horizontal wind turbine while option two entailed building a friction based
game. In the third alternative students have to showcase how creative they are by choosing and
building an individual plan.
