The development of several landing gear spring blades for lightweight aircraft is discussed. A special sandwich structure provided high longitudinal stresses in the faces and high shear stresses in the sandwich core. The length of the spring blades made a high bending stiffness necessary; therefore apart from glass fibers, reinforcements with higher Young-modulus as carbon- and Kevlar-49-fibers were also provided for tensile sandwich faces. All blades were statically and dynamically tested on a gravitational fall test-bed. Using Kevlar-49-fibers in the tensile sandwich face, the structural weight could be further reduced and damping conditions improved compared with the GRP-sandwich blade. (Author)
