Abstract

The article discusses certain issues and possible ways to partially solve the problem of remote landing, which may be useful in planning airborne operations to improve the safety of traditional parachute landing, as well as in further research and development of remote landing methods for airborne vehicles. Based on the results of the research, a method of remote landing of heavy equipment using a parachute-jet system is proposed, which allows to identify the weakest properties of the system, assess its overall level, characterised by a set of natural and climatic indicators, in particular wind speeds at different altitudes, and develop measures to improve the efficiency of the system's intended use. The results of the study demonstrate the ability of the WFD to move horizontally to the landing site at a considerable distance from the point of discharge by increasing the height of the release. However, it is much more difficult to calculate the specific amount of displacement without current knowledge of the many parameters that influence the wind drift rate. These parameters mainly include the air currents encountered by the WTG, which can help or hinder horizontal movement. Modern technology has made it possible to implement many innovative methods of cargo discharge. In order to reduce the impact of uneven airflows on drop accuracy, HARP (high-altitude release point) systems are now being used to improve the accuracy of high-altitude drops, which take into account airflow dynamics, system ballistics and aircraft speed.The ballistic table (based on the average ballistic characteristics of this parachute system) determines the drop point of the combat vehicle and calculates the free fall trajectory for a high altitude drop, taking into account the typical airflow profiles between the drop point and the landing site. To significantly improve the accuracy of high altitude drops, it is also possible to use an infrared Doppler laser locator to measure airspeed at different altitudes and create real-time 3D wind maps in the area between the aircraft and the landing site surface. Such systems are capable of making measurements with a typical error of less than one metre per second. The application of the research results in practice will increase the operational capabilities of the Airborne Assault Forces of the Armed Forces of Ukraine, namely, to ensure rapid deployment in threatened areas to deter the enemy by remotely landing heavy equipment, which in turn will significantly increase the combat potential of combat units in the operational and tactical depth of the enemy's defence.
