2. Handling Qualities Research (Germany)
Description: With the development of more capable helicopters and requirements to perform more demanding tasks in extreme atmospheric and visibility conditions, a requirement exists to define and produce aeronautical design specifications and standards to support the research, development, and acquisition communities. Ground-based and in-flight simulation studies are targeted to relate longitudinal, lateral, and directional response to control inputs and disturbances. Specific areas of concern are the investigation of cross-coupling requirements, gust rejection for rate response systems, and the response time delay limits for high bandwidth response systems.
Justification: The recently developed Airworthiness Design Standard (ADS 33) significantly addressed this requirement; however, gaps still exist in the data base which need to be filled to verify the defined criteria and new data are required for the extension of the elements. Current research cannot be adequately accomplished using national assets alone. Significant prior work utilizing Germany's in-flight simulator and correlated U.S. ground-based simulators has produced a viable data base to build upon even when a U.S. system becomes available. This work directly supports JTR, RAH-Comanche, AH-64 Enhanced Apache, and the construction and evaluation of simulation modeling tools.
Implementation: Handling Qualities Research is a task outlined under a current U.S.-GE Aeromechanics MOU with specific schedule and goals.
