Abstract

Heavy cargo parachuting off an aircraft is the fastest wat to deliver it to the uttermost remote and hard-to-reach areas. However, the pilot faces difficulties steering an aircraft while discharging a heavy cargo, due to the aircraft center of mass considerable changes. This problem aggravates now for several reasons. Firstly, the weight increase of heavy cargo, armored vehicles in particular. Secondly, the increase of speed range and dumping heights. The possibility of an “air start”, i. e. a spacecraft airplane launching at high altitudes, as well as rescue vessels air drop is considered. A free drop from deck levels of 5 ± 2 m is rather difficult due to the earth immediate proximity.

The possible solution to the piloting complexity problem consists in automation of this process. It is necessary to justify scientifically and methodologically the need and possibility of an aircraft control automation while heavy cargo extraction. Thus, the object of the study is the process of aircraft control while a heavy cargo extraction, and the subject of the study is its automation.

The research task are as follows:

1. Revealing the gist of the problem of the MTA flight parameters violation of operating limitations while heavy cargo extraction.

2. Analysis of the factors affecting the MTA piloting while airlift delivery.

3. Сonsidering the existing ways of solving the problem of the MTA flight parameters violation of operating limitations while heavy cargo extraction.

4. Analysis of the possible ways of MTA automation while airlift delivery.

The need for flight control automation was proved based on the study of the MTA flight parameters violation of operating limitations while heavy cargo extraction and consideration of the factors affecting this process. The results of the analysis of the existing ways of the abovementioned problem solution and possible ways of flight control automation allowed develop adaptive control algorithms for aircraft control while heavy cargo extraction.

It must be emphasized, that the detailed analysis of the abovementioned problem and rational ways of its solving under modern conditions were made for the first time and, furthermore, it seems expedient to carry out further studies on developing the automation technique based on adaptive algorithms with current identification.
