Aerologic Probe Return Module
Malalan, Nina ; Horpatzká, Michaela (oponent) ; Červenka, Miroslav (vedoucí práce)
Retrieving methods for in-situ upper-air measurement equipment are nowadays limited. A low rate of recoverability leads to a disposable radiosonde design that forces many worldwide meteo-stations to limit their measurement frequency. This leads to a decrease in the weather forecast accuracy. A possible feasible design of a lifting body that would provide a controllable radiosonde descend is here presented. The resulting vehicle is an outcome of comparing methods that aim to seek the most optimal choice to fulfil the mission requirements. A conventional fixed-wing configuration is here pursued by examining its basic components, and the chosen ones are sized based on a two-iteration-steps method reported in the thesis. Basic requirements for the vehicle autonomy are examined, and a design for a control system that would choose the best available landing location and fly the vehicle towards it is proposed. Furthermore, possible methods for payload installation are analysed and considered, and possible detachment systems are studied and compared. It is expected that by controlling the descent with such a vehicle, a more frequent measurement frequency could be performed, with more precise non-disposable measuring equipment. Consequently, lower amount of material would be used, which would lead to a lower amount of waste produced.

Vibration feedbacks in pilot-aircraft haptic interaction
Malalan, Nina ; Zikmund, Pavel
A research about different ways of encoding the distance information with vibrotactile feedback was done as part of a bigger project with the aim of designing a device which would help the pilot to achieve greater precision during the flight. Different kinds of stall warning devices and structural additions were already designed in the field of aviation, lingering only over attentional guidance. Therefore, a lack of spatial and movement guidance was detected. This paper lingers on this research which aimed to encode and evaluate haptic guiding methods.
