Turboprop powerplant installation into small twoseater airplane
Kövér, Ondřej ; Jebáček, Ivo (referee) ; Juračka, Jaroslav (advisor)
The diploma thesis deals with the problem of application of turboprop engine to a small 2-seater airplane. In the first part, reasons why the application is in considered are stated. Then, the air-plane is characterised, the choice of the most suitable engine, propeller and the weight analysis is made and the centres of gravity are calculated. For chosen engine and propeller, in chapter 6, the flight performance is calculated. In chapter 7 follows calculations of flight envelopes and the lim-it positive and negative load factor is stated. Flight envelopes calculations are followed by the calculation of engine mount loads of flight and ground cases. In chapter 9, the design of engine mount, inlet and outlet system and positioning of important elements are solved. The design part is followed by strength analysis of engine mount and its attachment into engine partition.

Remotorization of the L60 aircraft
Sahrai, Daniel ; Bartoněk, Jaroslav (referee) ; Imriš, Pavel (advisor)
The subject of the diploma thesis is the replacement of the power unit to the Aero L-60 "Brigadýr" aircraft. The reason for such a conversion is the ending life of the original power unit, accumulating technical problems and the effort to achieve higher aircraft performance during normal operation. In the introduction, the aircraft is introduced and there are mentioned the results achieved in the selection of a suitable power unit during the previous work. Furthermore, the work briefly deals with the issue of certification and selection of a suitable method that will lead to the approval of the change and to maintain the airworthiness of the aircraft. The work also addresses the effects of reconstruction on the center of gravity of the aircraft, which are minimized by the appropriate design of the engine mount. The model of such a engine mount was created in the computer software CATIA V5 and subsequently a strength analysis of nine loading cases was performed on it. Furthermore, an analytical inspection of the engine bed tubes on the struts and a check of the strength of the bolts connecting the engine mount to the aircraft airframe were performed. At the end of this work is described the practical installation of the engine and engine mount, including other engine systems.

Remotorization of the aircraft EV-55 Outback
Puller, Tomáš ; Weis, Martin (referee) ; Horák, Marek (advisor)
Thesis Remotorization of the aircraft EV-55 Outback deals with possibility of installationt piston diesel engine instead of turboprop engine PT6A-21. Begining of this thesis deals with choice of convenient engine and propeller. Then, 3D model of engine bed is designed, followed by mass analysis. Based on results from the mass analysis and requirements from the CS - 23 regulation, load is specified and stress analysis is done. The other part of this thesis deals with adjustment of the airframe and with calculation of flight performances. Finally, economic indices are specified.

Reconstruction of Sport Aircraft M-2 Skaut - Mounting of Power Unit.
Zakopal, Libor ; Vaněk, František (referee) ; Kubíček, Petr (advisor)
This diploma thesis deals with the design of an engine mount for the M-2 Skaut aircraft on the basis of LSA and CS-VLA specifications. It is divided into several sections: analysis of input conditions, determination of factors which influence the geometry, the main design and its verification using the Finite Element Method. The FEM is compared with an analytical solution to determine its accuracy. This thesis also deals with a selection of acceptable propelers for this engine along with a basic design of an oil and fuel system.

Retractible landing gear design for Z 143 LSi airplane
Gregor, Jiří ; Vaněk, František (referee) ; Píštěk, Antonín (advisor)
The diploma thesis deals with the design of the replacement the Z 143 LSi landing gear with the new VUT 100 type landing gear in a retractable system. The first part of this thesis is devoted to the description of the Z 143 LSi aircraft and its landing gear and the description of the retractable landing gear type VUT 100. The next part describes the possible variants of the installation the VUT 100 landing gear, which are critically evaluated. Then there is selected the final variant for the installation, which is designed in Catia V5 software. The final design includes remotorization with Lycoming IO-390 and new design of engine bed. For the proposed solution, a new mass analysis with the calculation of centrations, new cases of ground load, a new flight envelope of load and additional cases of load of a new engine bed are prepared. The proposed engine bed is analyzed by the finite element calculation method in the MS Patran software. Finally, a possible scheme of the chassis retraction system is proposed.

Rebuilding an airplane Z 142 with a LYCOMING power unit
Šurkala, Martin ; Horák, Marek (referee) ; Píštěk, Antonín (advisor)
The aim of this master´s thesis is to replace the current engine M 337AK of the aeroplane Zlin 142 for the engine of Lycoming type with an appropriate propeller. Another purpose of the study is the installation of a nose undercarriage of VUT 100 type. The first part of the thesis examines the alternatives of replacement engines. Here the individual engines are compared with regard to their flight characteristics (climbing etc.). The next part presents the calculation of new CG positions, flight envelopes and the load affecting the engine mount. Finally, the last part focuses on the constructional plan for the engine installation and the structural analysis.
