Abstract
The possibility of a significant flight range extension of a guided aerial bomb during climb bombing due to the jet thrust created by a solid-propellant rocket engine was considered. By means of simulation, a comparative analysis of the range of a guided aerial bomb equipped (not equipped) with a solid-propellant rocket engine under typical flight conditions of the carrier aircraft during level flight and climb bombing was performed. It was demonstrated that the use of a solid-propellant rocket engine, whose mass is 20 % of the guided aerial bomb’s mass, allows to increase the horizontal range of its flight at least twice.
Highlights
If we take into account that during climb bombing it is possible to implement a covert approach of the aircraft to the area of the guided aviation bomb (GAB) use, as well as that the climb bombing maneuver is a missile evasive maneuver, we can make the following conclusion
These results prove that the use of GAB equipped with solid - propellant rocket engine (SPRE) during climb bombing allows increasing the horizontal range to 8 500-10 500 m, which is almost twice as much as the horizontal range of GAB which is not equipped with SPRE
The simulation results showed that under typical conditions of climb bombing the GAB horizontal range is extended 1.3-1.4 times or by 30-40 % compared with level flight bombing, and constitutes 4 200-5 600 m
Summary
If it is necessary to provide a stealth approach of the aircraft to the attack zone, the most effective GAB maneuver is the flight of the aircraft at extremely low altitudes (H < 200 m) with maximum speed and climb (toss) bombing [2]. When performing such bombing, the use of an additional wing in the GAB design does not provide the expected flight range extension due to the fact that on the lifting leg of GAB trajectory with increased drag, generated by an additional wing, the GAB will decelerate. It is advisable to consider flight range extension of a GAB using a SPRE
