Vyhodnocení provozu tlakové kanalizace obce Hrádek u Sušice / Assessment of operation of the pressure sewerage system of the Hradek u Sušice villageMacsek, Tomáš January 2015 (has links)
The thesis deals with the assessment of a low pressure sewer system (LPS) in the village of Hrádek u Sušice during its test operation. It assesses the functionality of the LPS, parameters of operation and lists types of failures, which were found during the test operation, as well as the causes for the failings. For the purpose of determination of the LPS functionality and causes of failures, continual measurements of pressure have been made on selected sites followed by a thorough analysis of the data.

Návrh repliky letounu L-40 "Meta Sokol" - křídlo / Replica Design of L-40 "Meta Sokol " Aircraft - wingPluhař, Tomáš January 2008 (has links)
This diploma thesis targets in concept of wing, aileron, flap and main undercarriage of the ultralight replication of the plane L-40 called Meta Sokol. The thesis developed from cooperation with two other members of the team – Alice Lipková (aerodynamics, power) and Miroslav Růžička (fuselage, tail unit and rear gear). The first part of this diploma thesis is concerned with load and concept of structure of the wing. At first the flight envelope is specified, then charakteristics of shearing force, bending moment and torsion moment are determined spanwise. The concept and subsequent strength verification of structure of the wing is also solved. The same process is claimed to concept of the aileron and the flap. The second part of this diploma thesis is dealt with main landing gear, its support, structure, springing and the principle of retraction. The final passage is devoted to load of the undercarriage.

Návrh řízeni ultralehkého motorového kluzáku SONG / Designe of a control system for powered sailplane SONGCejpek, Jakub January 2011 (has links)
The objective of this work is to adopt and further expand the type design of the SONG motor glider. The study will result in the basic aerodynamic calculation and the design of lateral control system including structural strength inspection of selected parts. Subsequently, the proposal will allow for further calculation to be made (of flight mechanics, wings strength or fuselage and empennage firmness) and for more specific constructional design of individual components of the glider.

Indikace spalovacích tlaků zážehových motorůLinhart, Roman January 2018 (has links)
The thesis deals with the indication of combustion pressures of ignition engines. Introduction is devoted to thermodynamics of combustion engines and their diagrams. The following section describes the methods for measuring the combustion pressures of a spark ignition engine. This chapter describes three basic methods of measurement, the most described of which are piezoelectric sensors. The next part is devoted to the design of the measuring chain and to the description of the material used, which was used for the measurement on the engine under test. The main goal of the thesis was to evaluate the results obtained by measuring at the engine testing center of Mendel Uni-versity in Brno. The data were tabulated and graphically evaluated and subsequently described. At the end of the thesis everything is evaluated and the results summarized.

Numerická analýza bio-mimetického konceptu řízení proudu na povrchu křídla / Numerical analysis of bio-mimetic concept for active flow control on wing surfaceČermák, Jakub January 2017 (has links)
V této diplomové práci je provedena optimalizace profilu křídla vybaveného elastickou klapkou umístěnou na horní straně profilu. Optimalizační proces je proveden s vyžitím CFD prostředků, konkrétně URANS metody. V prvních kapitolách je popsána historie vývoje křídla vybaveného pohyblivými klapkami. Práce pokračuje popisem a zdůvodněním volby numerické metody. Vytvoření geometrie a výpočetní sítě je krátce popsáno. V práci je také prezentována validace a verifikace dané výpočetní metody. Případová studie je zaměřena na profil LS(1)-0417mod vybavený 20%, 30% a 40% dlouhou, pevnou kalpkou na různých úhlech náběhu. Aerodynamická účinnost společně s proudovým polem je analyzována. Je provedena nelineární pevnostní analýza s využitím MKP programu za účelem vyhodnocení ohybové tuhosti a deformovaného tvaru elastické klapky tak, aby byly splněný podmínky nutné pro automatické vychýlení.

Stanovení pracovního rozsahu a účinnosti vodního trkače / Determination of the working range and efficiency of the water hammer pumpRůžička, Jakub January 2019 (has links)
This thesis focuses on setting the range and efficiency of a water ram pump through experimental measurements in a laboratory. The measurements were carried out on three different constructions of water ram pump, each of the designed and assembled by the author of this thesis himself, to find out whether the weight on the pulsating valve has an influence on the water ram pump efficiency. Further on this thesis aims at the comparison of up to now methods of water transport arrangement used at a summer camp and the usage of the water ram pump and its advantages. The principal of water ram pump originates in hydraulic impact that is being precisely described in a great detail as well. On of the chapters even includes the placement manual for the water ram pump and its overall assembly and connexion. Because the presence of floating debris is inevitable, this thesis also deals with the possibility to solve the incoming water impurities by adding an inflow gating to prevent such problem. This inflow gating has only been designed in a Flow 3D programme to introduce the idea and functions.

Studie proveditelnosti průtočné MVE / Feasibility study of the small hydropower stationPatočka, Filip January 2013 (has links)
The aim of the present master’s thesis is to explore the feasibility of small hydropower plant for cur-rent hydro energetic potential of the weir on Ohře river, located in the city of Terezín in Ústecký re-gion, Czech Republic. The target of the thesis itself was to design minimally two variants of constructional and technological part. Due to requirements related to maintaining of all functions of the weir construction was decided to design small hydropower plant completely under the water surface, with flap mounted to the roof of the hydropower plant. Part of the thesis was also an economical assessment of designed hydropower project.
