The article deals with a methodical apparatus for calculating and constructing the optimal flight trajectory of a bomb when it is dropped by an aircraft during a flight with cabriolet. Optimization is based on the maximum horizontal range of the bomb after dropping. The use of this approach for the practical implementation of a bomb in an optimised trajectory allows the aircraft (carrier) to perform the entire flight and bombing at a low (extremely low) altitude. At the same time, the range of the aircraft from the target now of bombardment has been considerably increased, which altogether allows to significantly reduce the probability of its exposure to enemy anti-aircraft defense equipment. Based on this task, a ratio of bomb range to energy altitude is formed and a search for its extreme value is carried out. This enables the maximum bomb range to be achieved after the bomb has been dropped from the aircraft (carrier). It is substantiated and calculated that the derivative of the distance in energy height is practically an important characteristic. It shows how far a bomb can fly when consuming one meter of energy height. In the absence of an engine (accelerator) on the bomb, this derivative is negative in sign. This indicates that the total energy of the bomb changes over time, regardless of what maneuver it performs acceleration, braking, gaining height or descent. To test the efficiency of the method, the flight trajectory of the bomb was simulated, the geometric, mass and aerodynamic characteristics of which are close to the current serial sample. The comparison of both results indicates the adequacy of the proposed methodological apparatus.
The proposed methodological apparatus allows to determine the optimal conditions for the bombing of the calibration and to assess the impact of design and operational parameters on the range of the bomb.
