Design of a Crash-Test Dummy
Sedláčková, Martina ; Coufal, Tomáš (referee) ; Bilík, Martin (advisor)
The main objective of this thesis is construction of crash test dummy for vehicle-pedestrian crash tests. There is review of nowadays used crash test dummies types in the introduction of this thesis. This is followed by part describing construction itself. Chapter about construction begins by characterizing of used materials features in relation with real human body physiology. Main part of chapter is describing construction of crash test dummy’s skeleton and its individual components including 3D modelling and strength analysis. Thesis is finished by cost assessment.

Replica Design of L-40 "Meta Sokol " Airctaft - fuselage
Růžička, Miroslav ; Pešák, Miroslav (referee) ; Píštěk, Antonín (advisor)
This diploma thesis deals with the design of all-metal construction of fuselage of the replica L-40 Meta Sokol aircraft on the basis of CS-VLA regulation. As far as the aircraft is concerned, the thesis establishes the load of tail surfaces, landing gear and engine bed. Futhermore, it designs the construction of fuselage, tail landing gear, including the system of its retraction, wing-fuselage connection, engine bed and the primary design of cockpit. In the end, the thesis focuses on the fuselage production technology.

Design of composite aeroplane wing-fuselage joint
Sadovský, Hynek ; Šplíchal, Jan (referee) ; Juračka, Jaroslav (advisor)
This master's thesis deals with design, strength calculation and technological solution of wing-fuselage joint for composite four-seater aeroplane certificated by CS-23. Design is focused on optimal space utilization, low weight and simple manufacturing and assembly. Main output is technical documentation consisting of drawings and technological lay-ups. Conceptual design was chosen after analysis and weight estimation. With strenght calculation for composite materials it was possible to design composition of primary parts and also specify manufacture processes. Assigment was solved by unusuall conceptual design, which claims higher precision manufacturing, but it saves weight.

EV-55 aircraft modification for water level landing
Šponer, Jan ; Vaněk, František (referee) ; Chybík, Ladislav (advisor)
Diplomová práce se zabývá modifikací stávající pozemní verze letounu EV-55 pro možnost přistání na vodní hladině. Snahou je najít takovou variantu, která nepovede k výrazným konstrukčním zásahům do draku letounu a bude vyhovovat stavebnímu předpisu CS 23, zejména požadavkům týkající se plovatelnosti a stability na vodě. Je proveden hmotový rozbor modifikované verze a s tím související omezení hmotové obálky a rozsahu centráží. Zatížení od vody je spočítáno v souladu s CS 23. Pro toto zatížení je následně navrhnuto konstrukční řešení uchycení plováků k trupu a provedena pevnostní kontrola jednotlivých prvků a spojovacích uzlů. Tyto hodnoty jsou dále porovnány s pozemními případy zatížení a stanoveny součinitele rezerv. V závěru jsou spočítány letové výkony: maximální horizontální rychlost, stoupavost, dolet a vytrvalost.

Reconstruction of middle part of the fuselage Z 143 aircraft using semi- monocoque frame
Zamazal, Jakub ; Mališ, Michal (referee) ; Píštěk, Antonín (advisor)
The thesis is focused on reconstruction of middle part of fuselage Z 143 aircraft from truss frame to semi-monocoque frame. In the thesis there is a conceptual design of semi-monocoque middle part of fuselage. The spars of centre wing section are strength controlled. In thesis there is weight analysis according to use the semi-monocoque middle part of fuselage. In second half of the thesis there is a study of retractable landing gear. The thesis shows weight savings according to use a semi-monocoque frame. The thesis also shows that semi-monocoque frame allows other option to upgrade Z 143 aircraft. This thesis can serve as a feasibility study of the reconstruction of the middle part of the fuselage Z 143 aircraft.

Design of Trainer Aircraft with Tandem Seats
Dycka, Jan ; Urík, Tomáš (referee) ; Juračka, Jaroslav (advisor)
The diploma thesis deals with the project of composite constuction of aeroplane VUT 001 Marabu and its FEM stress-deformation analysis. The project of pilt´s cockpit is solved in the light of basic ergonomic requirements. Mass analysis, calculation and resulting selection of conclusive events of load are parts of the work. The results are applied on FEM model of fuselage and the state of stress in individual sections of composite structure are determined by the MSC Patran/Nastran system.

Structural design of fuselage and tail for racing model
Skála, Adam ; Hájek, Tomáš (referee) ; Pejchar, Jan (advisor)
This bachelor’s thesis surveys fuselage and empennage improvement of an already existing competition aircraft FabricK. Firstly, the introductory part explains the Air Cargo Challenge contest and describes the model. A research then presents possible empennage designs, which is followed by a brief overview of production F3B aircraft. The practical part of thesis introduces construction project of the empennage and the fuselage as well as a weight distribution analysis. Finally, the concluding part will evaluate the imporvement.
