The half-day class will illustrate the instrumentation challenges associated with acquiring physical measurements during flight test. Dynamic and electrical models for transducers will be discussed, as well as transducer mounting influences; cable associated errors; and necessary signal conditioning considerations. Data sampling guidance for resolution and rate will be provided, along with selection criteria for anti-aliasing filters. After signals are recorded, unique processes will be described, to enable documentation of the measurement’s system noise floor, as well as adequacy of system frequency capabilities for recorded signals. This latter process is titled "data validation," and is requisite for performing subsequent data accuracy analysis. Finally, a measurement system designer's checklist will be provided, as well as closing comments on the future of flight test instrumentation. This seminar will be conducted in an open classroom-style format, with a detailed overview of the types of instrumentation and related technologies used in this application environment.
The cost to attend this seminar is $100 USD per person, which includes seminar registration, lunch and handout materials. For more information, or to register, please visit www.aerotestamerica.com.
