Calculation and experimental investigation of the effectiveness of helicopter engine protection against foreign objects damage
Keywords:
Foreign object damage; hail; bird; protection net device.Abstract
Verification results of a CIAM’s mathematical model of damage of a net device protecting the helicopter engine from strike by foreign objects is considered. For this purpose a comparison of the calculation data to results of ballistic bench tests of an engine model under large hailstones and birds penetration is carried out. Efficiency of the protection device and sufficient adequacy of calculation models is shown. Great importance of protective net fastening conditions which affect estimation of its damages is thus revealed.Downloads
