ATMOSPHERIC TURBULENCE AND THE STABILITY OF FLIGHTS IN ZONE OF TROPOPAUSE AND JET STREAMS,
FOREIGN TECHNOLOGY DIV WRIGHT-PATTERSON AFB OHIO
In thhhe article an analysis is made of atmospheric turbulence, experienced by an aircraft both as bumps and bumpy air. There is ascertained the general conditions and distribution of turbulence aloft, the relationship between prevailing and maximum overloads affecting an aircraft, and the frequency of overloads there is investigated dependence of turbulence on geographic conditions on the stratification, type and slope of tropopause, wind speeds and jet streams, synoptic situation, and cloudiness. Flights of IL-28 sounding aircraft are used in regions of southeastern Kazakhstan. The range of the investigated heights is 8 to 12 km. Author
