Book excerpt: This project was initiated based on the goal of making the ride of the commuter aircraft as smooth as the ride experienced on the major commercial airliners. The objectives of this project were to design a digital, longitudinal mode ride quality augmentation system (RQAS) for a commuter aircraft, and to investigate the effect of selected parameters on those designs. The initial stage of this research was the development of an interactive control augmentation design (ICAD) program for use in the design and evaluation of the candidate RQASs. This computer aided design program included both optimal and classical design approaches for either continuous or digital systems, and provided data for analyses in both the time and frequency domains. Both optimal and classical RQAS designs were generated for the five flight conditions selected as representative of a typical commuter mission, using a Cessna 402B. These RQASs used direct lift flaps and the elevator for control of the longitudinal accelerations. The design parameters selected include the sample time, computation delay time, servo bandwidth, and the flap and elevator control power. Optimal and classical point designs, based on the nominal design parameters, are presented for all five flight conditions. Parametric analyses for all five flight condition for both the optimal and classical designs are also presented.

This book was released on 2018-07-17 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: The design of a Ride Quality Augmentation System (RQAS) for commuter aircraft is documented. The RQAS is designed for a Cessna 402B, an 8 passenger prop twin representative to this class of aircraft. The purpose of the RQAS is the reduction of vertical and lateral accelerations of the aircraft due to atmospheric turbulence by the application of active control. The detailed design of the hardware (the aircraft modifications, the Ride Quality Instrumentation System (RQIS), and the required computer software) is examined. The aircraft modifications, consisting of the dedicated control surfaces and the hydraulic actuation system, were designed at Cessna Aircraft by Kansas University-Flight Research Laboratory. The instrumentation system, which consist of the sensor package, the flight computer, a Data Acquisition System, and the pilot and test engineer control panels, was designed by NASA-Langley. The overall system design and the design of the software, both for flight control algorithms and ground system checkout are detailed. The system performance is predicted from linear simulation results and from power spectral densities of the aircraft response to a Dryden gust. The results indicate that both accelerations are possible. Suikat, Reiner and Donaldson, Kent E. and Downing, David R.

This book was released on 1989 with total page 1298 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cities and Their Vital Systems asks basic questions about the longevity, utility, and nature of urban infrastructures; analyzes how they grow, interact, and change; and asks how, when, and at what cost they should be replaced. Among the topics discussed are problems arising from increasing air travel and airport congestion; the adequacy of water supplies and waste treatment; the impact of new technologies on construction; urban real estate values; and the field of "telematics," the combination of computers and telecommunications that makes money machines and national newspapers possible.
