Dr. William R. Bertelsen is a great transportation inventor and visionary. He pioneered the creation of hovercraft (air cushion vehicles) in the 1950s, continued working in the decades since to perfect them with his Gimbal Fan, and recently laid the ground for a wonderful future of transportation with his Aeromobile-Aeroduct System. |

What has Dr. Bertelsen Done for Transportation? Dr. William Bertelsen is a medical doctor who also has an engineering background. Starting in the mid 1950s, Dr. Bertelsen was inspired by the experimental research done on vertical take-off aircraft to come up with the concept of an air cushion vehicle (a term he prefers, although the more common term is hovercraft). This is a vehicle that rides over any surface by creating a cushion of air. This air cushion enables the craft to hover above the ground and move in any desired direction. It has many advantages over wheeled vehicles, including being amphibious, not dependent on road surfaces and useable in many different terrain and weather conditions. Since his medical practice at the time was rural, he wanted to use such a machine to travel to his remote rural patients regardless of the weather. Dr. Bertelsen built an early prototype of a hovercraft vehicle in 1959 (called Aeromobile 35-B), and was photographed by a photographer from Popular Science magazine riding the vehicle over land and water in April on 1959. The article on his invention was the front page story for the July, 1959 edition of Popular Science. From that beginning, Dr. Bertelsen continued to innovate and promote air cushion vehicles throughout the years. He developed a number of hovercraft models that improved on earlier ones. In the later 1960s he created the most significant advance for air cushion technology - The Gimbal Fan. This device provides full cushion lift air in both vertical and horizontal directions, giving hovercraft much more stability and controllability. Gimbal Fan hovercraft are the best there is today in air cushion vehicles. Along with his inventions, Dr. Bertelsen founded this company, Aeromobile Inc., to promote hovercraft technology throughout this country and the world. In the mid 1970s, Dr. Bertelsen took hovercraft technology in an exciting new direction with his idea of the Aeromobile-Aeroduct System .His Gimbal Fan vehicles operate in a cylindrical groove (tube) and can be operated completely by automatic guidance. The result is an environmentally friendly, passenger safe, economically efficient solution to the many problems of ground transportion. The congestion, accidents, pollution and high cost of existing modes of transportation disappear with the implementation of the Aeromobile-Aeroduct System. In 1996, this new mode of transportation and its creator, Dr. Bertelsen, were filmed by the Discovery Channel as part of their show Extreme Machine s, which has been aired a number of times on the Learning Channel. This has helped bring worldwide recognition to this most important advance. Dr. Bertelsen continues to refine his air cushion vehicle technologies and talk to interested parties all around the world about the potential of hovercraft, especially the automated Aeromobile-Aeroduct System. He is convinced that the dismal picture today of polluted, gridlocked cities where transportation is getting more impossible is not necessary. The technology to alleviate the existing woes of ground transportation and prevent future problems is here right now with his inventions. He hopes he can convince enough others of this very practical vision. |
