On of the problems facing the aircraft community is landing gear dynamics, especially shimmy and brake-induced vibration. Shimmy and brake-induced vibrations can lead to accidents due to excessive wear and shortened life of gear parts and contribute to pilot and passenger discomfort. To increase understanding of these problems, a literature survey was performed. The major focus is on work from the last ten years. Some older publications are included to understand the longevity of the problem and the background from earlier researchers. The literature survey includes analyses, testing, modeling, and simulation of aircraft landing gear; and experimental validation and characterization of shimmy and brake-induced vibration of aircraft landing gear. The paper presents an overview of the problem, background information, and a history of landing gear dynamics problems and solutions. Based on the survey an assessment and recommendations of the most critically needed enhancements to the state of the art will be presented. The status of Langley work contributing to this activity will be given.

The book documents Glenn's many research specialties over those 75 years. Among them are early jet engines and rockets; flight safety and fuel efficiency tested in premier icing and wind tunnels; liquid hydrogen fuel which, despite skeptics like aerospace engineer Wernher von Braun, helped the U.S. win the race to the moon; and electric propulsion, considered key to future space flight. Space enthusiasts, aviation personnel, aerospace engineers, and inventors may be interested in this comprehensive and milestone volume.
