These models are constructed by three-dimensionally scanning two national- team ski jumpers taking flight postures. The drag and lift forces on each component of a ski jumper and skis (head with helmet and goggle, body, arms, legs and skis) and their lift-to-drag ratios are Keywords: obtained. For the two posture models, the drag forces on the body, legs and skis are larger than those Ski jumping on the arms and head with helmet and goggle, but the lift forces on the body and skis are larger than their Flight posture drag forces, resulting in high lift-to-drag ratios on the body and skis and low lift-to-drag ratio on the legs. -
Lesson Number Five : Snow Sports 1- Ski Flying : Is a Winter Sport Discipline Derived from Ski Jumping, in Which Much Greater Distances Can Be Achieved
Lesson number five : Snow sports 1- Ski flying : is a winter sport discipline derived from ski jumping, in which much greater distances can be achieved. It is a form of competitive individual Nordic skiing where athletes descend at very fast speeds along a specially designed takeoff ramp using skis only; jump from the end of it with as much power as they can generate; then glide – or 'fly' – as far as possible down a steeply sloped hill; and ultimately land within a target zone in a stable manner. Points are awarded for distance and stylistic merit by five judges, and events are governed by the International Ski Federation (Fédération Internationale de Ski; FIS). 2- Snowshoe running : or snowshoeing, is a winter sport practiced with snowshoes, which is governed by World Snowshoe Federation (WSSF) founded in 2010, which until 2015 had its name International Snowshoe Federation (ISSF). The snowshoes running is part of the Special Olympics and Arctic Winter Games programs. 5- Skiboarding is a type of freestyle skiing using short, usually double-tipped skis, regular ski boots and bindings, and no poles. It is also known as snowblading or skiblading. It is a recreational sport with no governing body or competition. The first mass produced skiboard was the Austrian Kneissl Bigfoot in 1991. American manufacturers such as Line Skis then began to produce skiboards, and the sport grew in popularity. From 1998 to 2000, skiboarding was part of the winter X Games in the slopestyle event. After it was dropped there was no longer a profession circuit for the sport, and many competitors switched to freestyle skiing on twin-tip skis. -

Kevin Bickner
Kevin Bickner Hometown: Wauconda IL (Norge Ski Club) Birthdate: September 23, 1996 Longest jump: 244.5m, Vikersund Norway, March, 2017 Kevin Bickner started jumping at the Norge Ski Club in Fox River Grove IL when he was nine years old and competed throughout the Central Division. As a member of five Junior National Teams, he was the silver medalist two years running before taking the championship titles in 2012 and 2013. Kevin was a member of three World Junior teams and finished an impressive 11th place in 2016. At age 16, Kevin was named to the USA Development Team and moved to Park City UT to train with the National Team. Kevin’s success on the FIS cup circuit quickly led to opportunities on the Continental Cup Tour. After establishing himself on the international COC circuit, and being named to the National Team, Kevin earned his chance to represent the USA in the Summer Grand Prix and then the World Cup where, as one of the youngest competitors, he scored his first points. In 2016, Kevin qualified for the opportunity to try his hand at Ski Flying on the HS 225 Ski Flying hill in Vikersund Norway. It was during this first ski flying experience that he flew a personal best 214.5m (2nd furthest in US history after Alan Alborn) and finished with his first World Cup score. One year later, in March of 2017, he smashed the US distance record by soaring 244.5m in Vikersund, Norway. Kevin currently attends DeVry University and splits his time training with the National Team in Park City and the National Team training facility in Slovenia. -

Development of a Speed Model for Terrain Park Jumps
Project Number: CAB-001 ` THE DEVELOPMENT & SOCIETAL IMPACTS OF A SPEED MODEL FOR TERRAIN PARK JUMPS An Interactive Qualifying Project Report submitted to the Faculty of the WORCESTER POLYTECHNIC INSTITUTE in partial fulfillment of the requirements for the Degree of Bachelor of Science By Heather M. La Hart Date: Professor Chris A. Brown, IQP Advisor 1. Safety Analysis & Liability Project Number: CAB-001 ABSTRACT The objective of this project was to develop ways to design safer terrain parks. Two separate models, The Geometrical Jump Design Model and The Speed Model, were developed and produced criteria for the initial design and predicted the speed for any jump. To understand the opinions of society on terrain park safety and this research, questionnaires were distributed within the skiing culture. Through field data and surveys it was found that utilizing terrain park design models and integrating them into society and terrain would mostly be welcomed and used. ii Project Number: CAB-001 ACKNOWLEDGEMENTS I would first like to acknowledge Dan Delfino a fellow friend and student at WPI for his ongoing and continuous help, additions, and support of this project over the past two years. I would also like to thank my advisor Professor Chris Brown for the inspiration of this project, his continuous hard but helpful criticism, advice, guidance, and support throughout the entirety of this research. I would like to thank Hanna St.John for providing me a place to stay while conducting my research and support in Colorado. I would also like to thank the resorts of Copper Mountain and Breckenridge Mountain which made collecting data for this research possible. -
