Design of Diesel Aircraft Engine One-cylinder Engine with Contra Rotating Pistons
Svoboda, Tomáš ; Drápal, Lubomír (referee) ; Novotný, Pavel (advisor)
Diploma thesis deals with design of crankshaft for two stroke opposed piston diesel engine. In the theoretical research part a history, comparison with competitive engines in nowadays light aircrafts and the advantages of opposed piston engines are mentioned. In the practical part the balancing is chosen and CAD model of crankshaft is designed. Geometry of this model is than checked for fatigue damage fallout. In the final part was chosen the propeller and appropriate reduction gearbox.

Design of elevator for pallets
Hájek, Lukáš ; Winkler, Tomáš (referee) ; Škopán, Miroslav (advisor)
The diploma thesis is focused on the construction design of elevator for pallets with car seats weighing 200 kg. This device is proposed for vertical transport of the load between two working positions which are separated by 6m. Part of the pallet hoist is a roller conveyor attached on a lifting frame. The roller conveyor allows loading and unloading pallets from the fixed roller conveyors in the lower and upper station. There are the functional calculations of important parts, strength control of traction belt and shaft of driving pulley drum. By FEM (Finite Element Method) is detected stress distribution of the lifting frame. Parts of the annex are the manufacturing drawings of the lifting frame, shaft of driving drum, the driving station and drawing of the whole assembly vertical conveyor. Furthermore, the timing diagram function for one cycle, risk analysis and FMEA.
