This book was released on 1955 with total page 642 pages. Available in PDF, EPUB and Kindle. Book excerpt: This 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 or read book Gust load and Airspeed Data from One Type of Two engine Airplane on Six Civil Airline Routes from 1947 to 1955 written by Walter G. Walker and published by . This book was released on 1956 with total page 25 pages. Available in PDF, EPUB and Kindle. Book excerpt: Approximately 70,000 hours of V-G data from one type of two-engine transport airplane were analyzed to determine the severity and frequency of occurrence of the gust loads and gusts. The data were obtained during routine feeder-line and short-haul commercial operations on six different routes from 1947 to 1955. The results obtained indicate that normal accelerations corresponding to the calculated value of limit-gust-load-factor increment may be exceeded, on the average, twice (once positive and once negative) within the range of 3,600,000 to 106,000,000 flight miles for the various operations. A derived gust velocity of 50 feet per second may be exceeded twice within the range of 800,000 to 23,500,000 flight miles. There were sizable variations among the different operations with regard to the loads, gust velocities, and operating airspeeds, but, in general these quantities were of the same order of magnitude as those experienced in past operations of the same type of airplane.

Copp and published by . This book was released on 1956 with total page 664 pages. Available in PDF, EPUB and Kindle. Book excerpt: Time-history data of airspeed, altitude, and acceleration obtained with the NACA VGH recorder from a twin-engine airplane operated by a regional feeder airline in the Rocky Mountains are evaluated to determine the magnitude and frequency of occurrence of gusts and gust accelerations and the operating airspeeds and altitudes. The results obtained are compared with the results previously obtained from a representative short-haul and long-haul operation.
