“…This step was done using a framework for data networking called the ring buffered network bus (RBNB). 8 The concept used for ATW testing had an RBNB process transferring data from the telemetry stream to a memory cache. The data in the cache were converted from generic telemetry units, such as counts, into engineering units, such as acceleration in g, for use with analysis processes.…”

The utterometer is an on-line tool that indicates a measure of distance to utter in terms of a ight condition during a ight test. The measure of distance is computed as a robust utter margin by applying ¹-method analysis to consider the worst-case effects of modeling uncertainty. The approach is to update the robust utter margin at a series of test points by analyzing ight data. The utterometer was used during an envelope expansion of the Aerostructures Test Wing. This paper describes the results of that ight test. Algorithm and implementationdetails that are critical to the successful application of the tool are discussed. Also, ight data and analysis are presented to demonstrate the utterometer operation. The ight test demonstrated that the utterometer is able to predict a conservative estimate of the utter speed.

“…The first step in the flutterometer implementation was to gather data from the aircraft telemetry stream. This step was done using a framework for data networking called the ring buffered network bus (RBNB) (18) . The concept used for ATW testing had an RBNB process transferring data from the telemetry stream to a memory cache.…”

A flight test to demonstrate flutter and evaluate the flutterometer

et al. 2003

A project was recently completed that investigated the ability to predict the onset of flutter using tools like the flutterometer. This project used an experiment called the aerostructures test wing that was flown while mounted to the flight test fixture on an F-15. Several flight tests were conducted to expand the envelope and determine the aeroelastic dynamics of the experiment. The final flight ended with destruction of the experiment due to the onset of flutter. The flutterometer attempted to predict this onset by analysing the flight data. The results indicate the flutterometer is able to generate a conservative estimate of the flight conditions associated with flutter. This paper details the flight tests of the experiment and the resulting predictions from the flutterometer.
