FIELD: test equipment.
SUBSTANCE: invention relates to the field of strength testing of aircraft, in particular, compressive strength testing of stringer panels made of layered polymeric composite materials. Device contains rigid clips, connected by tightening bolts, spacer sets of prismatic sliding inserts. Tightening bolts are installed inside the holes in the end zone of the panel with a gap of at least 0.5 % of the diameter of the tightening bolt, and the spacer sets of prismatic sliding inserts include central and side liners, which are mounted with a loose fit on the tightening bolt.
EFFECT: possibility to improve the accuracy of reproducing the boundary conditions when testing experimental samples of wide stringer panels from prospective PCM in laboratory conditions.
