Replica Design of L-40 "Meta Sokol " Aircraft - wing
Pluhař, Tomáš ; Jebáček, Ivo (referee) ; Píštěk, Antonín (advisor)
This diploma thesis targets in concept of wing, aileron, flap and main undercarriage of the ultralight replication of the plane L-40 called Meta Sokol. The thesis developed from cooperation with two other members of the team – Alice Lipková (aerodynamics, power) and Miroslav Růžička (fuselage, tail unit and rear gear). The first part of this diploma thesis is concerned with load and concept of structure of the wing. At first the flight envelope is specified, then charakteristics of shearing force, bending moment and torsion moment are determined spanwise. The concept and subsequent strength verification of structure of the wing is also solved. The same process is claimed to concept of the aileron and the flap. The second part of this diploma thesis is dealt with main landing gear, its support, structure, springing and the principle of retraction. The final passage is devoted to load of the undercarriage.
Wing fatigue safe life investigation of single-engine multipurpose aircraft
Hubáček, Jan ; Juračka, Jaroslav (referee) ; Chybík, Ladislav (advisor)
Práce se zabývá stanovením bezpečné únavové životnosti křídla. Letadlo, které bylo podrobeno analýze, je vzpěrový hornoplošník celokovové konstrukce. Letadlo je certifikováno na základě předpisu FAR 23 Amendment 23-46. Výpočet bezpečné únavové životnosti musí být proveden v souladu s požadavky předpisu FAR 23 a jeho poradními oběžníky.\\ Teoretická část práce je věnována hlavně přehledu literatury a představení projektu, kde byla stručně shrnuta jeho historie vzniku. Část přehledu projektu také pojednává o podstatě požadavku na posouzení bezpečné únavové životnosti zadavatelem. V další části byl rovněž proveden rozbor literatury týkající se únavy. Jednalo se zejména o rozbor předpisu FAR 23, jeho poradních oběžníků a obecně literatury vztahující se k únavě jak v letectví, tak v obecném strojírenství.\\ Druhá část diplomové práce byla zaměřena zejména na výpočetní analýzu a vývoj specializovaného software. Výpočetní část obsahovala zejména přípravu vstupů, včetně obálek zatížení, stanovení typického letu, výpočet zatížení křídla a napjatostní analýza ve vybraných řezech křídla. Z výstupů prvotní analýzy se následně provedl výpočet poškození a životnosti pro daný typový let.
Design of the two seater ultralight aircraft with consideration the price and simplicity of the construction
Machala, Martin ; Píštěk, Antonín (referee) ; Jebáček, Ivo (advisor)
The object of the diploma thesis is a conceptual layout of two-seater metal ultralight aircraft which has simple construction and with respect to low price. The preamble of the work deals with concept, layout and technology of aircraft. As next part are solved an aerodynamic characteristics, a determinative of centre of gravity position and a performance. Last of all is strength of wing.
Design of Sailing Boat
Křížová, Barbora ; Řezníček, Svatopluk (referee) ; Křenek, Ladislav (advisor)
The topic of this master‘s thesis is design and analysis of a sailing boat in accordance with ergonomic and technological requirements. The goal is to create a sailing boat, which will be modern, visually interesting and which and which will take future development of both design and technology into account.
The development of fighter aircraft until 1950
Smýkal, Michal ; Koštial, Rostislav (referee) ; Bencalík, Karol (advisor)
This bachelor thesis deal with history of fighter aircrafts in the period since start of World War I until 1950. There are examined the main developement sources of the period, used constructions and materials. The most important characteristics of the aircrafs are showed in the graphs.
Preliminary aerodynamic analysis of remotely controlled model with jet propulsion
Novák, Ondřej ; Zikmund, Pavel (referee) ; Popela, Robert (advisor)
This bachelor´s thesis deals with aerodynamic analysis of unmanned aircraft and subsequent changes to design of wing, its position and wing-fuselage junction. In this work emphasis is laid on flow separation, its interaction with other flow structures and its influence on aerodynamic properties. The goal of these changes to the aircraft is ensuring sufficient stability and controllability in low as well as high angle of attack flight. AVL, XFLR5 and CFD methods were used in the thesis. In case of inaccuracy of CFD calculation, two backup wing related modifications were prepared.
Design of Darrius rotor as source of electric energy
Novotný, Martin ; Houfek, Martin (referee) ; Vlach, Radek (advisor)
This bachelors thesis deals about possibilities to use alternative energy source - wind. Model of Darrieus rotor was build for learning purposes using accessible materials and tools. The build model was tested and measured to discover real functionality and characteristics.
Electrically powered plane conceptual design
Ševčík, Igor ; Sklenář, Filip (referee) ; Popela, Robert (advisor)
The master’s thesis deals with conceptual design of a new electrically powered aircraft as assignment for Evektor, s.r.o. company. In the first part of thesis there is more detailed elaboration of small aircraft statistics and their comparison. Thesis then concentrates on assigned parameters and requirements for design. Next section continues with the most important part of thesis, which is optimization of wing used for aircraft design and also analysis of its characteristics. The problematics of preliminary verification of flight performances as well as aircraft dimension design and follow-up weight analysis with consideration of power cells placement is described thereafter. A few different flight configurations is taken into consideration within weight analysis. Final part contains evaluation of optimization and design process.
Comparison of analytical and numerical solutions for buckling of an aluminium alloy profile
Bolek, Robert ; Šebek, František (referee) ; Návrat, Tomáš (advisor)
This bachelor thesis deals with the solution of buckling stability of a thin-walled profile made of aluminium alloy Al 6061.T6. The solution is carried out by analytical and numerical methods. The Abaqus software, based on the finite element method, was used for the numerical solution. The aim was to determine the maximum load on the profile by different methods, following with their comparison and evaluation according to the accuracy, versatility and time requirement of each method.
HPH 2 Twin Shark glider loading calculation
Pělucha, Jiří ; Jebáček, Ivo (referee) ; Juračka, Jaroslav (advisor)
The object of diploma thesis is a loading determination for strength calculation of HPH 2 Twin Shark glider matching the requirements of Certification Specification for Sailplanes (CS-22). Loading of the wing, tail section, fuselage and undercarriage is determined in this work.
