Determining the Optimal Conditions for Dropping a Load from an Aircraft

Optimum conditions for dropping a load from an aircraft are seen as conditions under which no collision with the aircraft is allowed, with stable flight of the load having a trajectory close to the calculated one. Depending on the aerodynamic characteristics, the weight of the load and the type of aircraft, it is necessary to determine the angle at which the load is attached to the aircraft, the initial angular velocity of the load at release, the forced vertical velocity of the load ejection, so that to prevent a collision with the aircraft. On the other hand, applying additional vertical speed to the load will reduce the detrimental effect of the disturbed air flow around the aircraft on its flight. All this is of great importance for ensuring the safe separation of the load from the aircraft and increases the accuracy of solving the targeting problem by a specific targeting system. Mathematical modelling of the flight of the load dropped by an aircraft with different initial vertical speeds of ejection was performed, for which the influence of the disturbed zone on the flight was investigated.
