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.

The design of the landing gear of the small two-seat airplane
Trojánek, Tomáš ; Katrňák, Tomáš (referee) ; Vaněk, František (advisor)
The aim of this master thesis is modification of landing gear for accomplishment CS-23 regula-tion from that purpose, because landing gear in the use can't pass this type of certification. The first part examines the alternatives of landing gear with consideration optimal technical and eco-nomical difficulty. After finding optimal type of landing gear with shock absorber is there part of designing and computing the load. Last part of thesis is about stress analysis of whole con-cept and reconsidering final changes.

Proposal of electro-hydraulic control system for the nose gear of small transport aircraft
Vodička, Petr ; Janhuba, Luboš (referee) ; Třetina, Karel (advisor)
The diploma thesis is focused on design of electrohydraulic system for nose gear control on small civil airliners. First part consists of brief review of small civil airliners, nose gears and CS 23 restrictions relevant for the design. In practical part a typical small civil airliner is defined and kinematic of landing gear mechanisms is designed. Then the electrohydraulic system itself is designed and parameters of some components are suggested. The wheel steering mechanism is simulated and, in conclusion, the whole system is evaluated.

Design of VUT200 TwinCobra landing gear
Novák, Josef ; Horák, Marek (referee) ; Katrňák, Tomáš (advisor)
The goal of following master thesis is to design variety of configuration and retraction options of VUT200 TwinCobra landing gear. For each option are a wheel base and a gauge set up by possibility of main landing gear retraction. Next, CS 23 demands and stress analysis are followed. There is a view of twin engine aircraft landing gear disclosed as well.

Overview of principles of landing gear door actuating
Rajnštajn, David ; Junas, Milan (referee) ; Mališ, Michal (advisor)
This thesis relates to airplane nose landing gear doors. It is divided into two main parts. At first, there it is put an overview of recent construction layouts at different airplane types. The second part is devoted to particular aircraft EV-55 Outback produced by Czech company Evektor. The aim of this work is to suggest adjustments and changes to current configuration, trying to make the mechanism open and close the door during the extension of the nose landing gear, with respect to the recent state of the fuselage and minimal changes to it.

Modification of the landing gear of the Irbis aircraft
Forman, Tomáš ; Vaněk, František (referee) ; Šplíchal, Jan (advisor)
This master thesis deals with the landing gear rebuild from tail gear to nose gear of the M-4 Irbis aircraft. The first chapter presents the aircraft in its current state and includes some technical data, too. The theoretical information about types of landing gears, its characteristics, pros and cons and the typical representatives for each type of landing gear are mentioned in the second chapter. The third chapter is about landing gear loads that occur during landing and about the load calculation according to UL 2 regulation. The following chapter shows the construction of the new landing gear, including some of the suggested, but not realised, designs. In the fifth chapter, there is a landing gear strength calculation of some of the gear components. The calculation is analytical and then uses FEM. The very last chapter then shows the effect of new landing gear on the centre of gravity in its extreme positions. The chapter also compares aircraft masses with both landing gears.
