Abstract
Zadatak je rada analiza slijetanja svermirske letjelice HL-20 s konfiguracijom nosećeg tijela po povratku iz orbite. Aerodinamički koeficijenti letjelice oblikovani su prema podacima izmjerenim za model letjelice u zračnom tunelu te su modelirani kao funkcije napadnog kuta i kuta klizanja metodom „nadogradnje“ koeficijenata (engl. Coefficient build-up method) te su nadograđeni inkrementalnim koeficijentima koji predstavljaju utjecaj položaja kontrolnih površina (zakrilca i kormilo visine), podvozja i utjecaja tla. Prema dobivenim aerodinamičkim koeficijentima, dimenzijama i zadanim parametrima letjelice prilagođen je model slijetanja materijalne točke u programskom jeziku MATLAB. U MATLAB-u je potom provedena analiza slijetanja prilagođenog modela. Analiza je provedena za četiri faze slijetanja letjelice. Analizirane su promjene visine, kuta propinjanja i brzine letjelice u ovisnosti o vremenu i koordinati x, te promjene napadnog kuta, otklona visine kormila, kutne brzine, normalnog opterećenja i koeficijenata 𝐶𝐿, 𝐶𝐷, 𝐶𝑍, 𝐶𝑋 i 𝐶𝑚 u ovisnosti o vremenu.
Abstract (english)
purpose of this paper is to analyze the landing of the HL-20 lifting-body spacecraft upon it's return from the orbit. The aerodynamic coefficients of the spacecraft are formed based on data measured for a model of the spacecraft in a wind tunnel and are modeled as functions of angle of attack and sideslip angle using the coefficient build-up method. Incremental coefficients representing the influence of control surface positions (flaps and elevator), landing gear, and ground effect are then added. Based on the obtained aerodynamic coefficients, dimensions and specified parameters of the spacecraft, a material point landing model was adapted using the MATLAB programming language. Subsequently, an analysis of the adapted model's landing was performed in MATLAB. The analysis was carried out for four phases of the spacecraft's landing. Changes in altitude, pitch angle, and spacecraft velocity were analyzed with respect to time and x-coordinate, as well as changes in angle of attack, elevator deflection, angular velocity, normal load factor, and coefficients 𝐶𝐿, 𝐶𝐷, 𝐶𝑍, 𝐶𝑋 i 𝐶𝑚 with respect to time.
