A Review and Analysis of Existing Guided Precision Airdrop Systems

Abstract

The development of airdrop systems for special landing sites of rocket-space techniques, such as rocket engines or boosters of the first stages of launch vehicles, which are salvageable or reusable, is an actual problem today. The traditional parachute systems don’t always provide the necessary accuracy for completing a flight task, and this significantly increases the risk of dangerous situations for civilians and infrastructure. The article is devoted to the study of the analysis of existing guided precision airdrop systems. The design features of various types of guided precision airdrop systems and their technical characteristics are consid- ered. The main advantages and disadvantages of the considered guided precision airdrop systems are determined. Based on the analysis, a typical design scheme has been developed for a typical representative of the family of guided precision airdrop systems. It is shown that the exploitation of experimental tests of the developed typical structural scheme with a physical dynamically similar model is the most effective and rational. A dynamically similar model has been developed for testing the automatic control system and for conducting experimental studies of the design of controlled systems for guided precision airdrop systems. The prospects for further research are discussed and aimed at developing a family of controlled systems for guided precision airdrop systems through the use of an experimental system for testing modifications to the layout and designs of the basic model using the principle of scaling according to the theory of similarity.
