Abstract
This study covers the issues of the security system in civil aviation. The relevance of the topic is conditioned by a qualitatively new approach to the design of civil aviation, since the modern equipment has the means intended for rescue directly in the area of contact of an emergency aircraft with the ground. When hitting the ground, as a rule, the lower part of the airframe is crushed, the fuselages break in the centre wing section, and the interior equipment breaking off is very traumatic to passengers, the engines are extremely fire and explosion dangerous, which leads to an emergency situation developing into a catastrophic one. The purpose of the study is to investigate the existing security system of a civil aircraft and develop the modification of aviation equipment with the help of collective rescue systems. Two main areas of application of collective rescue systems in aviation technology are analysed. As a solution to the problem at hand, a modification in the form of a parachute system of collective rescue is proposed. A detailed description of the system operation with the use of the necessary calculations for weight, aerodynamic and similar costs is given. The system under study relates to aviation technology and can be used in the development of transport (passenger, cargo, business class, etc.) aircraft. The proposed modification would significantly increase the level of flight safety due to a preventive measure that would exclude the contact area of the emergency aircraft with the ground.
Highlights
A characteristic feature of modern aircraft (Tu-334, Yak-42, A-310, B-737, etc.) is the low safety of passengers and crew in the emergency event that develops into a catastrophic situation [1], [2], [3], [4], [5]
The fuselage of the aircraft is equipped with a collective rescue system, consisting of a parachute system attached to the detachable part of the fuselage, a system for separating the rescued modules
The disadvantage of such a layout scheme is the low safety of passengers and crew in the event of an emergency, which is associated with the equipment of the aircraft with means that provide rescue in the area of contact of the emergency aircraft with the ground [17]
Summary
A characteristic feature of modern aircraft (Tu-334, Yak-42, A-310, B-737, etc.) is the low safety of passengers and crew in the emergency event that develops into a catastrophic situation [1], [2], [3], [4], [5]. Despite the apparent simplicity in this situation, all the weight, aerodynamic, and other costs need to be summed up, taking into account the differential mass increment of both units and the design of the airframe and systems. For these reasons, despite the fact that this system would meet the requirements of the aviation market, it is necessary to take into account the deterioration of the weight coefficient by weight of an empty equipped aircraft, and, a decrease in the commercial load or flight range
