Available in PDF, EPUB and Kindle. Book excerpt: A study has been undertaken to define hand-ling qualities criteria for V/STOL aircraft. With the current military requirements for helicopters and airplanes as a framework, modifications and additions were made for conversion to a preliminary set of V/STOL requirements using a broad background of flight experience and pilots' comments from VTOL and STOL aircraft, BLC (boundary-layer-control) equipped aircraft, variable stability aircraft, flight simulators and landing approach studies. The report contains a discussion of the reasoning behind and the sources of information leading to suggested requirements. The results of the study indicate that the majority of V/STOL requirements can be defined by modifications to the helicopter and/or airplane requirements by appropriate definition of reference speeds. Areas where a requirement is included but where the information is felt to be inadequate to establish a firm quantitative requirement include the following: Control power and damping relationships about all axes for various sizes and types of aircraft; control power, sensitivity, d-amping and response for height control; dynamic longitudinal and dynamic lateral- directional stability in the transition region, including emergency operation; hovering steadiness; acceleration and deceleration in transition; descent rates and flight-path angles in steep approaches, and thrust margin for approach.

This book was released on 1970 with total page 53 pages. Available in PDF, EPUB and Kindle. Book excerpt: The report presents criteria on handling qualities for VTOL and STOL aircraft. Included with each criterion is a discussion pointing out the pilot's reasons for including a particular handling quality feature. The criteria are based on results of tests using piloted ground-based simulators, variable stability aircraft, particular models of VTOL and STOL aircraft, and variable stability helicopters.

Download or read book An Analytical Study of V/STOL Handling Qualities in Hover and Transition written by R. L. Stapleford and published by . This book was released on 1965 with total page 174 pages. Available in PDF, EPUB and Kindle. Book excerpt: The hover analysis considers pilot attitude and position control tasks in the presence of horizontal gusts. The effects of each of the stability derivatives on the difficulty of the control tasks and on the closed-loop gust responses are determined. It is clearly shown that the handling qualities studies of control sensitivity and angular damping must consider the influences of M sub u (or L sub v) and should include gust inputs. These conclusions are substantiated by previous variable-stability-helicopter experiments. The effects of vehicle size and geometry are investigated by several approaches. The key result of increasing size is found to be a reduction in M sub u and L sub v which can, in turn, lower the requirements for control power and damping. The handling qualities during transition of two vehicles, a tilt duct and a tilt wing, which were previously tested on a simulator are analyzed. It is shown that both trim control and perturbations about the trim conditions must be considered. In fact, part of the increased difficulty in landing transitions, in comparison with takeoff transitions, is due to more difficult trim control; the much more stringent position control requirements in landing are also a contributing factor.

Download or read book A Flight Investigation of Lateral-directional Handling Qualities for V/STOL Aircraft in Low Speed Maneuvering Flight written by Karl-Heinz Doetsch and published by . This book was released on 1970 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: An investigation to determine the ranges of various lateral directional characteristics required to provide adequate flying qualities for turning maneuvers at low speed was undertaken using an airborne V/STOL aircraft simulator. Five parameters were varied in a systematic manner: the damping ratio, the frequency, and the ratio and the frequency of the numerator of the roll-angle to aileron-control-input transfer function. The pilots performed a low speed, visual maneuvering task and documented their assessment of the characteristics through extensive comments and a numerical rating. The report presents all the data categorized with respect to the test parameters. (Author).

This book was released on 1964 with total page 71 pages. Available in PDF, EPUB and Kindle. Book excerpt: The recommendations, which are necessarily tentative, particularly as regards their application to large aircraft, are based in some respects on requirements for U.S. Military helicopters, but considerable use has been made of the results of flight assessments of handling qualities of a number of V/STOL research aircraft. To improve their validity, they should be kept under continual review by critical, systematic comparison with the accepted handling qualities of as many new V/STOL aircraft as possible.

This book was released on 1968 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: "This report presents a series of discussions on selected topics related to the development of VTOL flying qualities criteria. The topics were chosen on the basis of their importance to flying qualities and the potential significance to the Air Force VTOL Integrated Flight Control System (VIFCS) program. The treatment given to the selected topics was aimed at identifying those areas that require further study and research within the scope of the VIFCS program. -- page iii.
