Popis:	In the tactical schemes of modern air conflicts, where the aircraft is subject to antiaircraft hits, the frequency of operations is very high. The present experimental study concerns two aspects. The preliminary one is devoted to the influence of the simulated gunfire damage on the aerodynamic performance of a typical aircraft model for different sizes and positions of the hole on the wings. The secondary one deals with the recovery of the lost performances by means of damage repairs using patches of different thicknesses and shapes applied at different damage locations (intrados, extrados, andboth). Theobtained resultsindicatesignificant aerodynamic coefficients degradation dueto damage,dependingontheholediameteranditsspanwiseandchordwiseposition,whereaspatchrepairsallowoneto achieve substantial recovery of the aerodynamic losses in relation with the different aforementioned situations.
