This report describes the state of the art inlanding gear design with a particular focus on shock absorbes. It gives an overview on the general design solutions and installation of landing gears into the airframe. An emphasis is placed on the function and calculation of loads acting on oleopneumatic shock absorbers, which are the main type of shock absorber considered within ADLAND. One part of this dokument covers the requirements which are the basis of the shock absorber design, materials used and related future developments within aerospace industry. A brief summary is given on research performed on active shock absorber so far.
