Ballistic Studies of the Rotational Motion of the Artillery Projectile into Account the Equatorial Damping Moment

The problem of calculating the equatorial damping moment during trajectory flight is an actual inballistic studies rotational motion artillery projectiles. practice ballistic research needs short algorithmsthat make it possible to calculate together with calculations parametersunder conditions continuously changing characteristics oncoming flow. In this regard, a simplified methodfor projectiles in flow proposed, based onthe differentiation dependence for overturning aerodynamic by angle attack and Machnumber Calculations parameters 155-mm artilleryprojectile on have been carried out. influence theperiodic components angular displacements projectile revealed. results calculationswith loss stability showed destabilizing effect equatorialdamping boundary terms case opposite directions rotation ofthe crosswind.
