National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

VTOL Handling Qualities Criteria Study Through Moving-Base Simulation.

AD863818

Publication Date	1969
Personal Author	McCormick, R. L.
Page Count	617
Abstract	An investigation of VTOL longitudinal and lateral handling qualities in hovering and low-speed maneuvering flight was conducted on a moving-base simulator. The simulator included an external display, and the task performed by the participating pilots was a visual rather than an instrument task. Pertinent longitudinal and lateral stability derivatives were varied in a wide range of test configurations. Most of the cases investigated included the effects of steady winds and turbulence. For part of the program, stick force gradients existed on the simulator control stick; for part of the program, they did not. For most of the cases, the pilot selected optimum control sensitivities. In all cases a pilot rating and pilot comments were given. Other data resulting from the simulations include probability density and power spectral density analyses. Pilot performance for part of the task also was calculated. (Author)
