Guidelines for Preparing Master's Theses
LIQUID FORCE KITE CONTROL SYSTEM DESIGN A Senior Project submitted to the Faculty of California Polytechnic State University, San Luis Obispo In Partial Fulfillment of the Requirements for the Degree of Bachelor of Science in Industrial and Mechanical Engineering by Brendan Kerr, Alden Simmer, Brodie Sutherland March 2017 ABSTRACT Liquid Force Kite Control System Design Brendan Kerr, Alden Simmer, Brodie Sutherland Kiteboarding is an ocean sport wherein the participant, also known as a kiter, uses a large inflatable bow shaped kite to plane across the ocean on a surfboard or wakeboard. The rider is connected to his or her kite via a control bar system. This control system allows the kiter to steer the kite and add or remove power from the kite, in order to change direction and increase or decrease speed. This senior project focused on creating a new control bar system to replace a control bar system manufactured by a kiteboarding company, Liquid Force. The current Liquid Force control bar has two main faults, extraneous components and a lack of ergonomic design. Our team aimed to eliminate unneeded components and create a more ergonomic bar. By eliminating components, the bar would also be more cost effective to produce by using less material and requiring less time to manufacture. We first conducted a literature review into the areas of kiteboarding control systems and handle ergonomics. Based on studies done on optimal grip diameters for reducing forearm stress we concluded that the diameter for the bar grip should be at least a centimeter less than the maximum grip of the user. -

Taking to the SKIES Canaan Valley Is No Stranger to Birds, but Now It’S Welcoming flyers of a Human Variety
Taking to the SKIES Canaan Valley is no stranger to birds, but now it’s welcoming flyers of a human variety. WRITTEN BY JESS WALKER 22 WONDERFUL WEST VIRGINIA | JUNE 2019 For paragliding pilots, nothing compares to the thrill of sailing over hilltops and trees. irds make flight seem majestic. They swoop and soar over valleys with the wind in their feathers and sun on their backs. Yet, for humans, most of our experiences with flight are less grandiose. It’s difficult to conjure a sense of wonder crammed in the middle seat of a giant metal Btube, unsuccessfully trying to drown out the engine’s thrum with an in-flight movie. But some daredevils in the Canaan Valley have found an alternative way to take to the skies— one that doesn’t require an engine, checked baggage, or even a ticket. And it’s significantly more majestic than flying coach. Gliding in Canaan Valley Picture a parachute. Now, stretch that mental image until the circular chute becomes a long cigar shape. That’s a paragliding wing. A pilot, suspended in a harness, maneuvers the wing by tugging on lines and shifting her body weight. If the conditions are right, she can stay afloat for hours at a time. Paragliding as a recreational activity didn’t gain momentum until the 1970s and ’80s. Credit is commonly given to mountain climbers who wanted an easier way to descend from climbs. The sport is not to be confused with hang gliding, which employs a v-shaped wing with a rigid metal frame, the equipment typically weighing more than 45 pounds. -

Beginners Guide to Kite Boarding
The Complete Beginner’s Guide About Kitesurfing What Is Kitesurfing? For some, it does not even ring a bell although, for others, it means everything and they build their life around it! Whether you have already witnessed it in person on your last vacation to the beach, maybe over the internet in your news feed or even in pop culture, for sure it made you wonder… What the heck are these guys doing dangling in the air under that big parachute? And how are they even doing it? If we were to talk to someone in the early 1960s about space exploration, let alone landing on the moon they would have thought we were crazy. What if we were to tell someone today that they can have the time of their life by practicing a water sport that involves standing up on a surfboard, strapped in a waist harness while being pulled along by a large kite up 25 meters in the air? That person probably wouldn’t believe it. Well, here we are today with hundreds of thousands of people learning and practicing kiteboarding every year. In this Complete Beginner’s Guide, we will go from the inception of the sport to where it is today and everything in between to understand what kitesurfing is all about. This guide will inform you about the history and origins of kitesurfing, the equipment, the environment, what it takes to become a kiter as well as the benefits of becoming one. Moreover, we will cover everything there is to know about the safety aspects of this action sport and the overall lifestyle and culture that has grown around it. -
