Posibilities of reduction of airliners fuel consumption
Harasim, Tomáš ; Třetina, Karel (referee) ; Kaddour, Mirvat (advisor)
Due to the long-term economic crisis, various economy measures have been implemented in different fields, including aeronautics. On that ground, this bachelor’s thesis deals with methods to reduce fuel consumption of transport aircrafts. Effected by these methods, not only spending on the fuel is reduced but the lower consumption, also, results in lower air pollution. In order to fully understand this dilemma, fuel supply systems and flight modes are worth describing. Further, the thesis contains a selection of twenty aircrafts that demonstrate the continuity of fuel consumption and plane weight. Provided existing airplanes, modulations are being implemented instead of new aircraft purchases. These modulations are performable, mainly, due to constructional alternations as well as new approaches to the flight control. The methods are included in the last chapter.

Aircraft jet engines with adaptive cycle
Heczko, Nikodem ; Šplíchal, Miroslav (referee) ; Klement, Josef (advisor)
In this final bachelor thesis is a basic overview and distribution of gas turbine engines, including a brief description of their function. The work is focused on jet engines with adaptive cycle. It introduces benefits of their use as aviation fuel units in terms of efficiency and description of possible ways to design solutions. Secondly, it analyzes the very principle of adaptive cycle and its implementation on the engine YF120. In conclusion are presented research programs dealing with adaptive cycle.

Aircraft Engines till the End of WWII
Falta, Libor ; Drápal, Lubomír (referee) ; Dundálek, Radim (advisor)
Bachelor’s thesis deals with aircraft piston engines until end Second World War. Thesis surveys about known, the most use and non-traditional types of engines in timeline. At the beginning it deals about history of aviation and the first use of piston engine as power source energy for controlled flight. There are high requirements on aircraft piston engines. Improving construction and increasing output of engines. In every chapter typical construction and the most powerful engines of the period are described. Thesis includes influence of both World Wars and some prestigious racings, which considerably accelerated global development. Explain the limit for increase output of piston aircraft engines in the last part.

Thermodynamics of jet engines
Bártek, Petr ; Charvát, Pavel (referee) ; Štětina, Josef (advisor)
This research introduces the reader to a brief analysis of various types of aircraft engines, with particular focus upon jet engines. Amongst the types of jet engines which will be covered are turboprop, turbojet, turbofan, ramjet, propfan, & the pulse engine. This body of work investigates the construction, operation and characteristics of these engines, including a analysis of their thermodynamic working cycle & the power of thrust produced. The main objective is to achieve a full comparison of the different kinds of engines using variables such as efficiency, fuel consumption and emission production.
