Learning outcomes and competences:
Organization and preparation of atmospheric aircraft in-flight tests. Organization of strength tests. Distribution of loading and design test equipment and test program. Bonding strain gauges and measurement strain. Acquiring theory, experience, measurement.
Prerequisites:
Basic knowledge of flight mechanics and strength analyses of aircraft structure.
Course contents:
Division of tests and specialties of aircraft testing. Basic metrological operation, measurement equipments in aerospace engineering. Calibration of instruments. Measurement of basic aircraft characteristics, aerodynamic correction. Preparing in flight test and aircraft before flight test. Measurement of flight performance and characteristics. Reduction measurement values to ISA. Static and dynamic strength tests of aircraft structures. Proposal and importance static and dynamic test. Equipment for implementation of test, measured instruments. Test of pressure cabin. Strain gauge measurements.
Teaching methods and criteria:
The course is taught through lectures explaining the basic principles and theory of the discipline. Exercises are focused on practical topics presented in lectures. Teaching is suplemented by practical laboratory work.
Assesment methods and criteria linked to learning outcomes:
Conditions for awarding the course-unit credit: 80% participation in practical exercises, submission of completed computational and laboratory exercises and protocols. The credit is necessary for registering for the examination. The exam I consists of written (the essential one) and oral parts.
Controlled participation in lessons:
Exercises are compulsory. It is possible to compensate missed exercises (in justified cases) by elaborating of a substitute assignment.
