Design of Electric Cargo Truck
Blahynka, Roman ; Zdařil, Zdeněk (referee) ; Sládek, Josef (advisor)
This master‘s thesis pertains to the design of a cargo truck with battery electric drivetrain. The presented design offers a solution which respects the technical requirements of such a vehicle, ergonomic needs of its crew, and demands on the aesthetics of a modern commercial vehicle. In consideration of the chosen drivetrain, this solution is proposed as a concept with an outlook of 10 to 15 years in the future. In keeping with the specified goals, this vehicle offers a novel appearance which attempts to characterize the electric drivetrain with certain visual elements, includes solutions that are readily available or currently in development, and optimizes ergonomics for maximum user comfort and safety.

Electrically powered plane conceptual design
Ševčík, Igor ; Sklenář, Filip (referee) ; Popela, Robert (advisor)
The master’s thesis deals with conceptual design of a new electrically powered aircraft as assignment for Evektor, s.r.o. company. In the first part of thesis there is more detailed elaboration of small aircraft statistics and their comparison. Thesis then concentrates on assigned parameters and requirements for design. Next section continues with the most important part of thesis, which is optimization of wing used for aircraft design and also analysis of its characteristics. The problematics of preliminary verification of flight performances as well as aircraft dimension design and follow-up weight analysis with consideration of power cells placement is described thereafter. A few different flight configurations is taken into consideration within weight analysis. Final part contains evaluation of optimization and design process.

Safety of automated industrial valves in operating conditions
Kryštof, Ondřej ; Trávníček, Petr (referee) ; Kotek, Luboš (advisor)
Choosing suitable and safe valve with accessories depends on general specifications for plant. Using valve for on/off, throttling, back-flow prevention, etc., pressure drop is related with Kv value or leakages from piping systems are main factors for properly valve selection. Valve have to resist chemicals and substances that may change the state, temperature and its fluctuation, pressure, corrosion and erosion. This properties determine pressure class, temperature resistance, connection into pipe and sealing material as gland packing, seats, seal between flange etc. This and other specification, listed in this thesis, can help determine suitable type of valve. This thesis deals construction design of valve and accessories as well. The last chapters are focused on calculation of safety valve and selection safe and appropriate control valve with accessories.
