Book Synopsis A Flight Investigation of an Automatic Gust-Alleviation System in a Transport Airplane by : Paul A. Hunter
Download or read book A Flight Investigation of an Automatic Gust-Alleviation System in a Transport Airplane written by Paul A. Hunter and published by . This book was released on 1961 with total page 98 pages. Available in PDF, EPUB and Kindle. Book excerpt: A flight investigation has been conducted of an automatic gust-alleviation system designed primarily to improve riding comfort in rough air. The gusts were sensed by a vane located on a boom ahead of the airplane. The wing flags moved in response to the vane in such a way as to counteract the change in wing lift due to the gust and a portion of the elevator moved to counteract pitching moments due to flap deflection. In the final configurations, inboard portions of the wing flaps also moved in such a way as to counteract the change in angle of attack at the tail due to the gust. The result indicate alleviation of normal acceleration of up to about 60 percent at the natural frequency of the airplane (0.6 cycle per second) and about 40 percent at 2 cycles per second. A further increase in riding comfort was achieved by a simultaneous alleviation of pitching velocity. For this particular airplane, gusts having frequencies greater than 1.5 cycles per second at a speed of 130 knots had little effect on riding comfort. Brief tests were also made of a configuration intended for reducing structural loads and of a configuration utilizing an accelerometer as the gust sensor. The gust alleviation capabilities of these configurations were somewhat less than that of the optimum configuration with vane-type gust sensor.

Book Synopsis Clear Air Turbulence, a Bibliography, 1950-1967 by : Dorothy E. Bulford
Download or read book Clear Air Turbulence, a Bibliography, 1950-1967 written by Dorothy E. Bulford and published by . This book was released on 1968 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: Clear air turbulence encounters can occur unexpectedly without any visual evidence or warning. As operations of higher altitude aircraft increase, the phenomenon is encountered more often. Clear air turbulence is defined as 'all turbulence in the free atmosphere of interest in aerospace operations that is not in or adjacent to visible convective activity (this includes turbulence found in cirrus clouds not in or adjacent to visible convective activity).' This bibliography consists of 578 references to technical reports, articles in periodicals, and books published during the past 17 years. References about other forms of turbulence such as that occurring with storms and airplane wake vortices are not included. (Author).

Download or read book Analysis of a Vane-controlled Gust-alleviation System written by Robert W. Boucher and published by . This book was released on 1956 with total page 45 pages. Available in PDF, EPUB and Kindle. Book excerpt: A theoretical study using an electronic analog computer has been made of the response to step gusts of an airplane equipped with a system in which modified wing flaps and a modified elevator are operated to reductions accelerations in rough air. These surfaces are actuated by an automatic control system in response to the indications of an angle-of-attack vane. The effect of interconnection of the flap operating mechanism with the pilot's control system is also included in the study.

Book Synopsis Initial Results of a Flight Investigation of a Gust-alleviation System by : Christopher C. Kraft
Download or read book Initial Results of a Flight Investigation of a Gust-alleviation System written by Christopher C. Kraft and published by . This book was released on 1956 with total page 19 pages. Available in PDF, EPUB and Kindle. Book excerpt: The results indicate that the gust-alleviation system is at least capable of reducing the normal accelerations due to gusts by 50 percent at a frequency of 0.6 cycle per second, the natural frequency of the aixplane, and by 40 percent at a frequency of 2 cycles per second. The controllability of the airplane with the gust-alleviation system in operation is adequate and it is felt that this type of control may result in improved handling qualities of the airplane.

Available in PDF, EPUB and Kindle. Book excerpt: The report indicates that a knowledge of angle of attack (alpha) and/or gust perturbation angle of attack (alpha sub g) is of prime importance for a longitudinal autopilot designed to alleviate the effect of vertical gusts. However, accurate measurement of alpha and alpha sub g is extremely difficult. This research indicates that the readily measurable normal acceleration factor (n) and pitch rate (q) can be used to provide alpha and alpha sub g information indirectly. (Author).
