PROCEDURE FOR EVALUATION OF THE APPLICATION’S EFFICIENCY OF THE PARACHUTE SYSTEMS FOR THE AIR DROPPING

The article proposes a procedure for evaluation of the application’s efficiency (AE) of parachute systems (PS) for the air dropping (AD). Based on the analogy with the index of combat effectiveness of armament and military equipment, the AE of PS can be evaluated by using the typical mission performance probability of AD - personnel or cargo positioning to site, while maintaining their combat capability to accomplish a mission of the parachute assault force. In this formulation, the process of accomplishing the typical mission of AD consists of the following stages: delivery of cargo to the airborne objective area, the exit of the aircraft to the computed air release point, the actual air dropping. Further analysis showed that the most influential factors affecting successful accomplishment of the typical mission of AD by the stages are: the reliability of the aircraft, the ability to overcome the enemy air defense without consequences for the accomplishment of AD, the property retention of PS while in flight considering flying conditions of the aircraft to the area of ​​the AD, problem solving of determining of the computed air release point under the actual conditions, the accuracy of the aircraft's exit to the computed air release point, the reliability of the PS, the covertness of the AD, the accuracy of cargo’s landing to the size-defined site, speed of the cargo’s landing. For each of the factors, the calculating formulas were defined in the article in the form of the probability of a positive influence on the successful accomplishment of the mission of the AD. The product of all these probabilities is evaluation of the AE of PS. For example, the calculations of the AE of PS DPS and Status-CH types in equal conditions of AD and Status-CH by using various tactical techniques of AD were made. The results of the calculations are completely consistent with the logical considerations and practice of the PS application, which testifies to the adequacy of the proposed procedure and the feasibility of its application.
