Geometrical characteristics. 2.1.1.1. The impactor consists of six joined zones whose forms and positioning are shown in Figures 1 and 2. The zones are defined as 500 ± 5 mm x 250 ± 3 mm in Figures 1 and 2. The 500 mm should be in the W direction and the 250 mm in the L direction of the aluminium honeycomb construction (see Figure 3).
2.1.1.2. The impactor is divided into 2 rows. The lower row shall be 250 ± 3 mm high, and 500 ± 2mm deep after pre-crush (see paragraph 2.1.2. below), and deeper than the upper row by 60 ± 2 mm.
2.1.1.3. The blocks must be centred on the six zones defined in Figure 1 and each block (including incomplete cells) should cover completely the area defined for each zone).
Geometrical characteristics. 2.2.1.1. The front plates are 1,500 ± 1 mm wide and 250 ± 1 mm high. The thickness is 0.5 ± 0.06
Geometrical characteristics. 2.1.1. The impactor consists of six independent joined parts whose forms, sizes and positioning are shown in figure 1.
2.1.2. The deformable impact zone shall be 1,500 ± 10 mm wide and 500 ± 5 mm high.
2.1.3. The ground clearance shall be 260 ± 5 mm measured in static condition before impact.
2.1.4. There shall be six deformable elements, divided into two rows of three elements. All the elements shall have the same width (500 ± 5 mm) and the same height (250 ± 3 mm); the elements of the upper row shall be 440 ± 5 mm deep and those of the lower row 500 ± 5 mm deep.
