    • In a nondestructive ultrasonic testing method for an implementation in a testing device, defects are installed in a testing area of a structural part by determining reflections on inhomogeneities in a testing area of the structural part. At least one ultrasonic transmitter is provided for coupling ultrasonic excitations into the structural part, and at least two ultrasonic receivers are installed for receiving structure responses to the excitations coupled into the structure. A number of testing points are determined and for each testing point and each location of the ultrasonic receivers, expectancy range data are determined and stored for signal forms being implemented in the testing device. When, an inhomogeneity is present in the respective testing point, excitations are reflected thereon and are measured by the respective ultrasonic receiver. The received reflection data are compared with the stored expectancy ranges to determine the location of a defect.
    • 在用于在测试装置中实现的非破坏性超声波测试方法中,通过确定结构部件的测试区域中的不均匀性的反射来将缺陷安装在结构部件的测试区域中。 提供至少一个超声波发射器用于将超声波激发耦合到结构部分中,并且安装至少两个超声波接收器以接收对耦合到该结构中的激励的结构响应。 确定多个测试点,并且对于每个测试点和超声波接收器的每个位置,确定并存储期望范围数据以用于在测试装置中实现的信号形式。 当在各测试点中存在不均匀性时,激发被反射在其上,并由相应的超声波接收器测量。 将接收的反射数据与存储的预期范围进行比较以确定缺陷的位置。

    • A cover skin for a variable-shape aerodynamic area, such as a wing structure, tail unit structure, control surface structure or flap structure is described. A cover skin is deformable in one direction without exhibiting substantial deformation in a transverse direction. A deformable framework structure is embedded in a layer of an elastic material, such as rubber or polymer. The framework structure may be comprised of non-deformable elements joined pivotably in auxetic and non-auxetic assemblies of elements that are capable of substantially eliminating transversal contraction, when the cover skin is longitudinal stretched, and substantially eliminating transversal expansion, when the cover skin is longitudinally contracted.

    • A cellular actuator device suitable for a control surface of an aircraft or space craft has a number of elementary cells which are combined to a common arrangement and are formed by pressure-tight chambers. The elementary cells can be acted upon by a pressure medium and, when acted upon by the pressure medium, can be deformed in at least one work direction while changing their length. The elementary cells are coupled for combining their length changes in the at least one working direction to an overall movement of the elementary cell arrangement. The actuator device is particularly suitable for actuating a control surface of an aircraft or spacecraft.
