This thesis is based on the series of scholarly article dedicated to the issue of pumping in the differential scanning chamber of an environmental scanning microscope. The thesis is based on Danilatos’s study where the pumping of the differential pumped chamber is solved by means of the Monte Carlo statistical method. The thesis analyzes gas flow in the experimental chamber using the Pipot tube. The analyses will be used for the design of the experimental chamber which will serve for the experimental evaluation of the flow results in the chamber using the continuum mechanics.

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.

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.
