Twin Engine Aaircraft Design for Commuter Category
Horák, Marek ; Jebáček, Ivo (referee) ; Juračka, Jaroslav (advisor)
This master’s thesis deal with design of EV-55 Outback airplane with pressurized cabin. In this thesis are given common principles and requirements of regulations on construction pressurized cabin. A necessary fuselage modifications and fuselage construction are included. Also construction and build up of air-conditioning system and emergency oxygen system are included. Some parts of this thesis are about weight and balance, definition of pressurized cabin load, simple stability analysis and basic flight performance calculation. At the end of this master’s thesis a result of weight and flight performances are compared with analogous airplanes by other producers.

Influence of wing design modification on aircraft polar curve
Mixová, Alexandra ; Matějů, Jiří (referee) ; Navrátil, Jan (advisor)
This thesis focuses on determining the polar curve of Roko NG aircraft, its evaluation and design of possible wing modification; on the influence of said modification on the polar curve and determination of basic flight performance. The introduction explains basic concepts and problems of aerodynamics. The following part discusses the particular type in comparison with similar ultralight aircrafts. Measurement determines the actual polar curve which can be compared to the analytically determined polar curve of the existing airplane, and to the analytically determined polar curve of the plane with modified wing. From this newly defined polar curve, the basic flight performance is expressed and compared with the flight performance of the existing aircraft.

Conceptual design of high performance glider with electric propulsion (in complience with EASA CS-22)
Hlůšek, Josef ; Sklenář, Filip (referee) ; Hlinka, Jiří (advisor)
This master's thesis is focused on conceptual design of glider with electric propulsion system following the CS-22 regulation. Statistical analysis of the glider with an auxiliary electric engine has been carried out in order to determine basic design parameters for conceptual design. Based on analytical drag polar, the flight performance parameters are calculated, in particular flight range and influence of the solar panels on the flight range. This thesis also includes preliminary design solution of accumulator placement within the wing.

Flight performance of the STOL light sport airplane
Koudelka, Jaroslav ; Sklenář, Filip (referee) ; Juračka, Jaroslav (advisor)
The aim of this bachelor thesis is to evaluate effect of individual parts of the selected aircraft on its aerodynamic characteristics and to summarize possible directions of aircraft modifications with taking into account increasing its cruising speed while maintaining STOL performances. The first part of this thesis is focused on the description of selected aircraft construction and its legislative categorization. Then follows the theoretical part describing the basic terms of horizontal flight mechanics, the creation of drag and drag types. The practical part contains the evaluation of the drag influence for individual aircraft parts, their possible directions of improving and the final summary how the modified parts influence flight performances. In conclusion they are results comparing the original aircraft configuration with the modified one with taking cruising speed into account. For the modified version there is an evaluation of its impact on the STOL performances.

Conceptual design of an upper wing aircraft using structures parts of the previous type
Koudelka, Jaroslav ; Katrňák, Tomáš (referee) ; Jebáček, Ivo (advisor)
The aim of this diploma thesis is to design a new high-wing aircraft for the company TL ultralight using the structural elements from another models from their portfolio. The design is created with an emphasis on crew comfort and cabin ergonomics. The first part of the thesis focuses on the description of the basic requirements for the aircraft and its classification in aviation regulations. It also contains a research part of competing types and currently produced type, which the proposed aircraft should replace in the company's portfolio. Then follows the characteristics of the individual parts of the airframe, the specification of the parts, which will be used from another types from portfolio, and parts which will be completely designed. Great emphasis is placed on the layout of the interior and its design and ergonomic. The proposed aircraft then demonstrates theoretical calculations of basic performances and a preliminary mass analysis. In the end, the benefits of the newly designed aircraft are evaluated with respect to the competing types.
