Development of Flight Test Techniques
IAR has developed a number of novel flight test techniques in conjunction with other flight test agencies to evaluate new or modified aircraft, to develop precise mathematical models of aircraft performance, and/or to evaluate new equipment.
Time / Frequency Domain Tests / Analysis
Parameter estimation frequency and time domain techniques are used to create a series of mathematical models from the in-flight measurements of inputs and outputs of dynamic systems. The extracted models make it possible to characterize the response of the overall aircraft to internal inputs and external forces. IAR has expertise in the area of parameter estimation for both airplanes and helicopters.
ADS33 Maneuvers (army)
IAR's simulation results form the cornerstone for the development of a new specification for helicopter handling qualities, the U.S. Army Design Standard ADS-33D. The uniquely realistic environment that the IAR facility provides for evaluation purposes is unsurpassed in the handling qualities community. The use of ADS-33C on military aircraft acquisition programs, and its application to the interpretation of operational difficulties with in-service rotorcraft, has shown that the knowledge base for helicopter handling qualities is far from complete.
Simulator Model Development
To improve the efficiency of parameter estimation, IAR has improved its air calibration flight test techniques by developing a Simultaneous Calibration of Air Data System (SCADS) procedure using DGPS. This process reduces the calibration time of a standard air-data system by a factor of 5 and eliminates the requirement of a chase aircraft.
Maneuvers for Evaluating Helmet-Mounted Displays
Existing standardized maneuvers (Aeronautical Design Standard ADS-33D) do not always provide sufficient information about the pilot's ability to fly while using an HMD. IAR has developed specific maneuvers designed to force pilots to make broad use of the HMD system's features.
