DOWNLOAD EBOOKTwo jet-propelled airplanes were flow at different speeds in rough air to investigate the effects of compressibility on applied gust loads at Mach numbers up to 0.68. The results indicated that no compressibility correction to the slope of the lift curve was necessary.

DOWNLOAD EBOOKThis paper presents the results of an analysis of approximately 100,000 hours of V-G data from one type of four-engine civil transport airplane to determine the magnitude and frequency of occurrence of the gust loads and gusts. The data were obtained during routine operations from 1947 to 1954 on five different routes. The normal accelerations for each of the five operations may be expected to exceed the value corresponding to the limit-gust-load-factor increment, on the average, twice (once positive and once negative) within the range of 5,000,000 to 22,300,000 flight miles. A derived gust velocity of 50 feet per second was exceeded twice within the range of 600,000 to 1,900,000 flight miles. The gust loads of the present operations were less than the loads experienced by other four-engine civil transports previously investigated, but the differences are not significant. The present data indicated only small differences due to seasonal effects and different operational utilization.

DOWNLOAD EBOOKAs a basis for the prediction of the gust-load history of airplanes in service operations, the statistical concepts of random variables and probability distributions are applied to the "sharp edge gust" formula. Expressions are derived for the frequency distribution of gust loads in terms of distributions of the related variables such as effective gust velocity and airspeed. Soultions are obtained under assumptions that appear reasonable on the basis of present practices in gust research. The results are applied in an example and the predicted load experience is compared with the available flight loads data for this case.
