Turbulence at Low Altitudes. Summary of the Results of Lo-Locat Phases I and II

  • F. K. Atnip


Operational speeds and structural flexibility of aircraft have continued to increase through the years as large strides in improved performance have been achieved. With this evolution, the role of atmospheric turbulence has become a significant consideration in aircraft design. Older generation aircraft, due to their relatively slow speeds, had to cope mainly with the low power, high frequencies of turbulence. The high speeds of modern aircraft cause their response frequencies to be coincident with the high power, lower frequencies of turbulence. It appears that future aircraft will be responsive to turbulence of very low frequencies where, in the past, little has been known about turbulence power characteristics. The detailed definition of turbulence behavior in this realm has, therefore, become pertinent.
