Behind the Scenes: Theme Parks 2009 COMPETITION SCENARIOS Get ready to experience engineering! TEAMS 2009 is taking students behind the scenes and showing them the engineering involved in designing, building and running America's theme parks! Every year millions of people get their adrenaline pumping by visiting one of the hundreds of amusement parks that’s synonymous with summer fun! In the United States alone, there are an estimated 300 million amusement park visitors tallying a total of 3 billion rides per year. Whether visiting Bush Gardens in Tampa Florida, Cedar Point in Sandusky Ohio, Silver Dollar City in Branson Missouri, any of the Six Flags or Disney Parks, entire families are having countless hours of entertainment. So who is responsible for making all of this fun and entertainment happen? Engineers! It takes engineers with all different backgrounds from a wide range of disciplines to create the amusement parks we enjoy. While all the work of these engineers takes place behind the scenes, their ultimate goal is to create exciting rides and activities while keeping the safety of all visitors and guests at the top of their priority list. Get active and explore how it all happens! JETS provides you with the following eight competition scenarios to offer a preliminary overview of the question content that will be posed during the 2009 TEAMS Competition. Scenarios may be edited and expanded upon in the questions of the actual competition; however the overall content will remain. Team members are encouraged to get started by researching the information contained in the scenarios including any unfamiliar terms in preparation for the competition. A short list of related links is also provided at the end of each scenario and contains information for more exploration. Needless to say, these links should not be considered all inclusive and team members/coaches are strongly encouraged to go beyond the provided list during research and preparation. Remember to visit the JETS web site—jets.org/TEAMS—frequently throughout the competition season for additional information and competition news. All statistical data included in the introductory section are 2005 rough estimates and were reported by T. Harold Hudson—All About Parks, Rides and Attractions Note: These scenarios are for reference use only and include links providing direct access to Internet sites not controlled or maintained by JETS.

Scenario #1 Biological, chemical and mechanical engineers are indispensable in maintaining the health and welfare of large water mammals participating in showcases of amusement parks around the world Water shows in amusement parks that specialize in marine animals are popular venues to teach visitors the importance of a quality marine habitat. Demonstrated at these shows are the tricks that trained sea mammals like whales and porpoises can perform. To keep these creatures healthy and happy, it requires a great deal of engineering design. Your team has been asked to design a new killer whale showcase called “The Orca Opera” to be located near St. Louis. You will be responsible for the mechanical systems and chemical processes necessary to maintain the appropriate environment for these large water mammals. The water must be filtered and chemically treated to eliminate bacteria and to remove organic matter. The water temperature cannot vary to the extremes of the local climate. Their health care and diet must be considered. Your engineering team may also be asked to plan for alternative missions for the facility such as possible research projects involving bottlenose dolphins. Get Active!

They combine animation, make-up effects, and electronics. Many engineers work in the field of animatronics for theme parks such as Universal Studios and Disneyworld. Developing a remote controlled Hulk, gorilla, or full-scale dinosaur requires the work of a specialized engineering team. The conceptual designer of a new attraction is interested in making people believe that the figure is alive via special effects such as the scent of bananas on King Kong’s breath. As an engineering team, you will work from that starting point to determine the feasibility of the special effect. To determine feasibility, you have to approach the problem from the perspective of safety, reliability, guest impact, and budget constraints. Get Active!

Roller coaster engineering is not limited to one engineering discipline. Rather, electrical, mechanical, structural, and other engineering disciplines are involved in the process. In this scenario your engineering team will be asked to improve an existing ride. An amusement park is celebrating the 30th anniversary of its opening. To commemorate this event, the park managers have made serious plans to make improvements to all aspects of the park, including its rides. Since the managers do not want to invest in a completely new ride, they decided, upon consulting a ride manufacturer, that the most economical decision was to add an inversion (loop, barrel roll. etc) to an existing ride. Your engineering team has been asked to determine the feasibility of the new addition and the effect it will have on the existing ride. The study should include mechanical, structural, energy and economical considerations. Get Active!

Construction engineers have the opportunity to turn those ideas into reality. Monorails are sometimes used in zoological parks to bring visitors closer to the animals without disrupting their habitat. Your team is to design structural components such as a vertical support pier and the guide rail beam between two piers such that it will perform adequately in all design conditions. In a MAGLEV monorail system, the lifting force of the electro-magnetic coils is just as important as sizing the heat sink for the solid-state triac switches used to control the electrical power to the coils. Providing electric power for lighting and air-conditioning to each car offers opportunities for innovative energy solutions such as flywheel storage, LED lights, and thermal storage. Your engineering team may also be asked to identify alternative on-board power solutions. Get Active!

The concerns expand to both the design and the construction phases of the vehicles. Your engineering team is asked to consider ways in which to assure the safety of the passengers who enjoy the rides. Many popular theme park attractions feature rides. There are a wide variety of ride vehicles, including roller coaster trains, motion simulators, boats, monorails, chain driven 'omnimovers', cars-on-tracks, locomotive trains and even wire guided vehicles. One thing that all of these rides have in common is the need for safety. This may be achieved through mechanical means, control systems or a combination of both. Your engineering team is asked to explore various methods for assuring ride passenger safety, including block zone systems, cycle testing of sensors and redundant control systems. Get Active!

This scenario will emphasize the numerous and multi-faceted design considerations that must be undertaken by roller coaster engineers. This scenario will give you a much greater understanding of what is involved in the design of a typical steel roller coaster. A new steel roller coaster is to be constructed in a new amusement park and your interdisciplinary engineering team has landed a contract for the design work. The ride will be rather standard for a steel roller coaster. Features will include a traditional lift hill, a sub-grade tunnel and soaring hills. Your team will be responsible for the design of mechanical systems such as the chain lift for the first hill; and structural systems such as the track and the members that support the track. Geotechnical engineers will provide you with existing soil conditions in order for you to design the foundations. Also, you will assist the contractor’s engineers in the estimation of materials and cost. Get Active!

Theme parks such as Kings Island and Six Flags attract many visitors with their array of exciting rides. Since the majority of the theme park season occurs during the summer months, these parks are able to include water rides. During the summer of 2008, Holiday World an Indiana Park announced plans to build Pilgrim’s Plunge, the world’s tallest water ride. The system is designed to lift a boat full of riders through an open elevator up to 131 feet and then to let the riders plunge at 45 degree angle and at speeds of 50 mph. The impact creates a wave of water 45 feet high and 90 feet wide. This problem scenario is similar to the Pilgrim's Plunge model. In order to design this type of a ride, engineers must consider the dynamics of the rides and their impacts on the park. The study of these impacts must be done in order to ensure the practicality and feasibility of the ride. In the design of a water slide, several parameters must be taken into consideration. These parameters include, but are not limited to, the fluid dynamics of the water being used on the slide, the power required by the slide’s water pump, and the effects on the riders. The energy usage and cost of running the water pump must also be considered. Your engineering team is charged with the task of completing the design calculations. Get Active!
