The landing gear system is tasked with repeatedly and reliably performing in a severe environment of loads, contamination, and temperature. The extreme nature of these requirements is reflected in the continued presence of landing gear systems near the top of the list of aircraft systems with regard to failure rates and total maintenance actions. With the landing gear strut in particular, design constraints of minimum weight and volume allowance coupled with the high loading have resulted in almost exclusive use of high strength steel and aluminum materials. However, these materials have essentially reached their limit of structural efficiency. Even higher efficiency materials are needed to keep pace with the weight reductions in composite airframes. Also, the conventional metals have a major problem with corrosion which results in considerable maintenance and overhaul tasking. Design and fabrication of a titanium matrix composite (TMC) F-15 nose landing gear (NLG) outer cylinder is discussed. Results of a field experience survey examining landing gear (LG) operations are also discussed. Weight, supportability and cost benefits are summarized for this component and projected for production applications of the material.
