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.

Modification of RAPID 200 Aircraft for Towing
Seďa, Ondřej ; Daněk, Vladimír (referee) ; Píštěk, Antonín (advisor)
This master’s thesis deal with design modification of the RAPID 200 (Skyleader 200) airplane for towing at compliance with maximum take-off weight 450 kilogramme. A necessary construction modification, a weight analysis these adjustments and a balance verification are included. The thesis contains of power plants installation consisting from the M 132 engine and the V 541.2 propeller, a towing gear and a landing gear, a load calculation of power plants and towing gear and basic flight performance calculation too. Last but not least valuation of operation ekonomy, operation characteristics assesment and a using of the airplane for specialized duty are included.

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.

Installation of the LYCOMING power unit into the Bristel UL aircraft
Kročil, Petr ; Juračka, Jaroslav (referee) ; Píštěk, Antonín (advisor)
This diploma thesis focuses on Lycoming drive unit mounting used in two-seater plane of VLA category (the very light aircraft). In the beginning characteristics of currently produced Bristell aircrafts are described. Following chapters aim at research selection of new drive unit mounting based on multi-criteria decision analysis. For selected unit, the weight, center of mass and flight performance are calculated. Additionally, the construction of engine mount is proposed. According to CS-VLA and CS-23 stress level of mounting is defined followed by strength verification. Later in this thesis, a suitable engine cover for engine and cockpit cooling is proposed. A complete fuel system is described in following chapter. Last chapter deals with financial costs of re-engining as well as aircraft operational costs.

Replica design of Aircraft "Meta Sokol" - Basic dimensions - technology
Lipková, Alica ; Šošovička, Róbert (referee) ; Píštěk, Antonín (advisor)
The object of the diploma thesis is a preparation of fundamentals for realization for replica of the aircraft L-40 „Meta Sokol“ matching the requirements of Certification Specification for Very Light Aeroplanes (CS-VLA). The preamble of the work deals with the changes made on the original aircraft necessary to satisfy the criterias of the above-mentioned specification. One of the main contents of the first part of the thesis is the definition of replica’s basic dimensions and preparation of aerostatic fundamentals, including longitudinal stability control. As next a suitable engine is chosen and calculation of corresponding performances is made. A detailed weight analysis and a determination of centre of gravity position (c.g. position), important for solving the stability of an airplane, is also presented. Finally, a brief description of the manufacturing process of individual components and also factors influencing the technology are discussed.

Proposal for the use of the Z 143 Lsi aircraft for aerobatic operation
Hub, Pavel ; Juračka, Jaroslav (referee) ; Píštěk, Antonín (advisor)
This master thesis deals with the impact of given construction changes on the Zlín Aircraft Z 143 Lsi aircraft, the purpose of which is to enable the aircraft to operate in the aerobatic category in accordance with FAR-23 certification guidelines. An important part of the thesis is the definition of permitted flight configurations with respect to the aircrafts´ structural strength limits and flight performance. Furthermore, impact of these changes on flight within the normal and utility categories is investigated. An overview of neccessary certification procedures is provided as well. The goal of the thesis is to supply the company with relevant technical documentation to decide on adequacy of the concept.

Design of VUT 051 RAY aircraft with hybrid power unit
Zeman, Petr ; Bencalík, Karol (referee) ; Píštěk, Antonín (advisor)
The master´s thesis deals with a design of hybrid power unit for a small aircraft. The Introductory part goes into the problems of hybrid power unit and describes its current use in aviation. In the next part of the thesis aircrafts VUT 051 RAY and Skyleader 600 are described and the aircraft with better aerodynamic characteristic is chosen. A suitable conception of hybrid power unit is proposed for this aircraft. On the basis of the proposed conception basic flight performance are figured out. After that a weight and blance analysis are made with the chosen power unit components and thair arrangement. In the final part electric motor mounting and a frame for holding batteries are designed.
