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 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.

Book Synopsis Gust Alleviation on a Transport Airplane by : J. Becker
Download or read book Gust Alleviation on a Transport Airplane written by J. Becker and published by . This book was released on 1985 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: An analytical study was performed to define a Gust Alleviation System on a preliminary configuration of a commuter airplane. The analysis takes into account the influence of elasticity of the airplane, unsteady aerodynamic effects, mechanical nonlinearities such as backlash deadzone and control surface rate and deflection limitations. A relatively simple model shows that ride comfort can be improved by at least 50%.
