Flow measurement of air by multiport averaging probes
Šimák, Jakub ; Uher, Miroslav (referee) ; Šedivá, Soňa (advisor)
Master work deals with the measurement of fluid flow (particularly air) pipe, with orifice and multiport averaging probe. The theoretical part is followed by practical, which verifies the properties of the measured system. In a next part of semestral work are verifies the properties of multiport averaging probes Vavra s.r.o. MQS-011 and Rosemount Annubar 485. Measured values from probes are compared.

Aircraft speed Measurement
Mokoš, Marian ; Jebáček, Ivo (referee) ; Zikmund, Pavel (advisor)
The Bachelor´s thesis is focused on the measurement of flight especially the speed of the aircraft. The first part includes the list of aircraft on-board instruments, measurement errors and the types of speeds. The principle of an aircraft speedmeters and the list of probes subdivided by measuring the speed of flight are mentioned. The second part is focused on unmanned aerial vehicle SPECTO and choosing the appropriate probe for this aircraft.

THE EFFECT OF PRIMARY FLIGHT INFORMATION FAILURE ON SAFETY AND RELIABILITY OF AIRCRAFT
Sklenář, Filip ; Badánik, Benedikt (referee) ; Juračka, Jaroslav (referee) ; Hlinka, Jiří (advisor)
It is necessary to have certain flight information available to control the airplane. This information is usually displayed on flight instruments, which are located on the dashboard of the aircraft. In case of loss of indication or misleading indication of certain devices, control of the aircraft can be very complicated or even impossible. The dissertation deals with the issue of loss of information indication from aerometric instruments (especially from the airspeed indicator). The work contains research on the course of degradation of total pressure measurements using a Pitot tube. Based on this research, it is possible to design a new system for detecting blockage of the Pitot tube, which will increase aviation safety. The phenomenon described was investigated in a wind tunnel and in real conditions. Furthermore, the work defines instructions for the compilation of an emergency procedure, which the pilot could use in the event of a fault condition with aerometric instruments. The real possibilities of use were demonstrated on a Cessna 172SP aircraft during the validation experiment. The validation experiment proved the possibilities of the safe usage of the emergency procedure during flight. The final part of the work is focused on the evaluation of possible changes in the creation of reliability and safety analyzes with regard to the application of new knowledge based on this work.

Supersonic Flow Measurement Within A Lowpressure
Area
Bayer, Robert ; Hlavatá, Pavla ; Bílek, Michal
The goal of this paper is to describe the idea of measuring a supersonic gas flow within low-pressure areas in order to describe its behavior and to compare the measurement data with the generally described supersonic gas flow behavior derived from its behavior within high-pressure areas. This data should help to make low-pressure supersonic flow simulations more accurate.

Design Of The Shape Of The Experimental Chamber For The Analysis Of The Pressure Layout In The Differential Pumped Chamber
Hájková, Věra
This article is based on a study of Dr. Danilatos, where pumping of the differential pumped chamber is solved using the Monte Carlo statistical method. Similar results were obtained using the Ansys Fluent system. Theoretical computations as Dr. Danilatos and comparative studies are performed on theoretical shape. Simulations were made to obtain the shape of an experimental chamber with complete pumping shapes so that its shaping and pumping would ensure such a flow of gas to ensure the same distribution of pressure in the experimental chamber in the area under investigation as in the theoretical shape.
