Mach, Tomáš ; Vaněk, František (referee) ; Jebáček, Ivo (advisor)
Tato diplomová práce se zabývá návrhem stavitelného stabilizátoru za účelem vyvažování letounu a zlepšení jeho letových výkonů. Cílem práce bylo navrhnout konstrukční řešení ovládání a zavěšení horizontálního stabilizátoru. Součástí je pevnostní výpočet kritických konstrukčních prvků a návrh letových zkoušek. V závěru jsou zhodnoceny výhody a nevýhody nového řešení a posouzení možnosti sériové výroby. Klíčová slova Ultralight, JA – 400, stabilizátor, stavitelný stabilizátor, vodorovné ocasní plochy, vyvážení. Abstract This thesis describes the design of adjustable stabilizer for the purpose of balancing the aircraft and improve its flight performance. The aim was to propose a design solution for control and hinge system of horizontal stabilizer. It includes the strength calculation of critical structural components and the design of flight tests. The conclusion evaluates the pros and cons of the new solutions and possibilities of mass production.

Landing gear design of two-seat airplane
Čavojský, Tomáš ; Pejchar, Jan (referee) ; Vaněk, František (advisor)
This diploma thesis deals with the landing gear design of the small two-seat aircraft. The introduction focuses on the conceptual gear design and shock absorber computational dynamic characteristic model. The practical part is focused on the landing gear construction according to the selected parameters based on the conceptual and computational model. The diploma thesis ends with strength calculations and production documentation.

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.

Flap otpitmization for SKYLEADER aircraft
Kácal, Jan ; Vaněk, František (referee) ; Koutník, Tomáš (advisor)
This diploma thesis focuses on optimization of the flap for the ultralight aircraft Skyleader JA 600, which is produced by the Jihlavan s.r.o. company. Individual types of flaps used in ultralight aircrafts are described in the initial phase of the thesis. In addition, description of the plane of interest Skyleader has been conducted, while along with the basic characteristics the focus is mainly on its wing and flap. The thesis continues with detailed CFD method calibration task, which is mostly focused on the basic turbulent models comparison. The optimization task conducted within this diploma thesis includes CFD calculations to determine aerodynamic characteristics of the flap provided by Jihlavan company, and subsequent determination of its optimal position. An important part of this thesis is also evaluation of the load and strength of the flap in previously determined optimal position. At the end, the strength and fly tests of the flap in the new position are described.

Design of VUT 081 Kondor aeroplane in double-fuselage variant
Suk, Filip ; Vaněk, František (referee) ; Píštěk, Antonín (advisor)
The aim of the diploma thesis is to determine loads of the empennages and the engine mount for the engine ROTAX 912iS of the VUT 081 Kondor aircraft. Further the thesis deals with a design of a stabilizer and of beams of empennage with fins. I also present a design of mountings for beams to the center wing box. The design is presented with regard to CS-VLA regulations and the ELSA regulation for modular construction.

Aerodynamic analysis of the glider flexible wing
Jurina, Marek ; Vaněk, František (referee) ; Navrátil, Jan (advisor)
This thesis deals with determination of effect of wing flexibility on load distribution. FSI analysis using modal superposition was used for determination of effect of wing flexibility. Analysis was verified by analytic calculation. Differences of load distribution, between rigid and flexible wing, was determined for the selected flight regimes. Change of the bending moment was up to 3,9 %. Thesis shows importance of including effect of wing flexibility for sailplane design.

Modification of the WT10 aircraft for the fixed landing gear according to the CS-23 requirements
Kubiena, Jaromír ; Juračka, Jaroslav (referee) ; Vaněk, František (advisor)
In this thesis, we deal with the design of a shock absorber variant for the type of main landing gear design of the aircraft WT10 Advantic. Then we focus on the design of the selected variant of the main landing gear. Next, we follow regulation CS-23 demands to calculate the load cases for the selected main lending gear. Then we design shock absorber based on the load during landing. We compile the equation of motion of the aircraft, which describes motion of the aircraft during landing, then we compute the equation. Finally, we focus on a stress analysis of the main landing gear and the shock absorber.
