Proračun performansi zrakoplova MIG-21 u uvjetima bliske zračne borbe ; Close Air Combat Performance Calculations for MIG-21 Aircraft

Bliska zračna borba se najčešće odvija između dva lovačka zrakoplova s ciljem uništenja protivnika. U njoj osim manevarskih mogućnosti zrakoplova, te borbenih značajki vođenih projektila zrak-zrak malog dometa (na vrlo malim udaljenostima mogu se upotrijebiti i topovi), značajnu ulogu igra i obučenost pilota, kao i njegova spremnost na riskiranje života kako bi ostvario cilj. Ovaj diplomski rad prikazuje osnovne lovačke manevre (BFM) koji se koriste na zrakoplovu MiG-21bisD, te ono što je pilotu potrebno kako bi izveo manevar što sigurnije i uspješnije. Pojašnjeni su i osnovni elementi koji utječu na performanse zrakoplova u letu. U eksperimentalnom dijelu, izračunima te korištenjem V-n i E-M dijagrama izvršeni su probni letovi koji su doveli do zaključka o mogućnostima zrakoplova MiG-21bisD u uvjetima bliske zračne borbe. ; Close air combat usually takes place between two fighter jets with the aim of destroying an opponent. In addition to the maneuverability of the aircraft, and the combat characteristics of short-range guided air-to-air missiles (at very short distances, cannons may be used as well), a significant role is played by the pilot's training and willingness to risk his life to achieve the goal. This graduate thesis presents the basic hunting maneuvers (BFM) used on the MiG-21bisD aircraft, and what it takes for a pilot to perform a maneuver as safely and successfully as possible. The basic elements that affect the performance of aircraft in flight are also explained. In the experimental part, calculations and the use of Vn and EM diagrams, test flights were performed, which led to the conclusion about the capabilities of the MiG-21bisD aircraft in close air combat conditions.
