Investigation of the Influence of the Installation of the Exhaust Device on the Flight and Technical Characteristics of the Helicopter Ми-24

Abstract

The article considers the results of installation of exhaust devices on the helicopter. According to the test results, the installation of screen and exhaust devices on the helicopter reduces its thermal visibility, but at the time affects the change in its flight and technical characteristics. Thus, conducting the test of the helicopter Ми-24 with the installed “Adros” screen and exhaust devices АШ-01В the characteristics of the load capacity, height gain of the practical ceiling, maximum flight speeds, stability and handling of the helicopter are investigated.
 When performing flight tests, most of them are occupied by flight studies for the study of flight and technical characteristics (LTC) of helicopters. Since the installation of screen and exhaust devices on the helicopter affects the change in its flight and technical characteristics, the assessment of the change of the LTC helicopter is mandatory. Methods and methods of flight studies on the evaluation of LTD were based on the works of V.S.Vedrov, A.P.P roskuryakov, M.L.Milya, G.S.Kalachov, L.M.Berestov, A.I.Akimov.
 Flight research is the main scientific activity of the State Scientific Research Institute for Testing and Certification of Weapons and Military Equipment and during modernizations, the development of various new weapons and equipment is an important scientific problem.
