Download or read book Evaluations of Helicopter Instrument Flight Handling Qualities Evaluation de la Maniabilite Des Helicopteres Pour Le Vol Aux Instruments written by S. R. M. Sinclair and published by . This book was released on 1982 with total page 49 pages. Available in PDF, EPUB and Kindle. Book excerpt: The NAE Airborne Simulator, a modified and suitably equipped Bell 205A helicopter, was used in experiments to provide background information on the handling qualities requirements for helicopter instrument flight. This investigation was in support of a regulatory review indertaken by the U.S. Federal Aviation Administration as part of an overall assessment of the helicopter certification process. The results illustrate the inter-dependence of the various stability and control characteristics which contribute to sate instrument flight handling qualities, and underline the importance of good mission simulation in conducting certification-related experiments.

Book Evaluation of the Effects of Lateral and Longitudinal Aperiodic Modes on Helicopter Instrument Flight Handling Qualities

Download or read book Evaluation of the Effects of Lateral and Longitudinal Aperiodic Modes on Helicopter Instrument Flight Handling Qualities written by S. R. M. Sinclair and published by . This book was released on 1983 with total page 27 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report describes a part of a larger program funded jointly by the US Federal Aviation Administration and the National Aeronautical Establishment to provide background information on instrument flight handling qualities of helicopter. This latest series of tests was aimed at addressing the acceptability of pitch and roll aperiodic characteristics when performing general handling and mission-oriented tasks in the NAE Airborne Simulator. In general, the results of these tests are consistent with proposed requirements for helicopter IFR handling qualities. Two significant factors were highlighted in these tests: aircraft characteristics which were not specifically under study may have affected pilot opinions; and changes in pilot opinion occurred depending on whether the task was one of general handling or was specifically mission-oriented.

Book Handling Qualities Evaluation of the OH 58A Helicopter Incorporating the Model 570B Three axis Stability and Control Augumentation System

Download or read book Handling Qualities Evaluation of the OH 58A Helicopter Incorporating the Model 570B Three axis Stability and Control Augumentation System written by Raymond B. Smith and published by . This book was released on 1973 with total page 90 pages. Available in PDF, EPUB and Kindle. Book excerpt: A limited handling qualities evaluation of the OH-58A helicopter with a Bell Helicopter Model 570B three-axis stability and control augmentation system installed was conducted to determine its capability to perform instrument flight. Testing was performed by the US Army Aviation Systems Test Activity at Edwards Air Force Base, California. The testing consisted of 25 productive flight hours and was conducted from September through November 1972. The evaluation revealed significant improvements in the aircraft handling qualities with the addition of the augmentation system. The most significant enhancing characteristics provided by the equipment were: (1) increased damping of the lateral-directional oscillation (Dutch roll), (2) improvement of aircraft spiral stability from neutral to convergent, and (3) reduction in pilot effort required to maintain trim flight conditions. This evaluation was of limited scope, and primarily addressed handling qualities. It did not provide a basis to qualify the aircraft for instrument flight.

Book A Piloted Simulator Investigation of Static Stability and Stability control Augmentation Effects on Helicopter Handling Qualities for Instrument Approach

Download or read book A Piloted Simulator Investigation of Static Stability and Stability control Augmentation Effects on Helicopter Handling Qualities for Instrument Approach written by and published by . This book was released on 1980 with total page 404 pages. Available in PDF, EPUB and Kindle. Book excerpt: A motion-base simulator was used to compare the flying qualities of three generic single-rotor helicopters during a full-attention-to-flight control task. Terminal-area VOR instrument approaches were flown with and without turbulence. The objective of this NASA/FAA study was to investigate the influence of helicopter static stability in terms of the values of cockpit control gradients as specified in the existing airworthiness criteria, and to examine the effectiveness of several types of stability control augmentation systems in improving the instrument-flight-rules capability of helicopters with reduced static stability. Two levels of static stability in the pitch, roll, and yaw axes were examined for a hingeless-rotor configuration; the variations were stable and neutral static stability in pitch and roll, and two levels of stability in yaw. For the lower level of static stability, four types of stability and control augmentation were also examined for helicopters with three rotor types: hingeless, articulated, and teetering. Pilot rating results indicate the acceptability of neutral static stability longitudinally and laterally and the need for pitch-roll attitude augmentation to achieve a satisfactory system. (Author).

Book Determination of Handling Qualities and Display Requirements for Helicopter Instrument Flight During Decelerating Approaches to Slow Speeds

Download or read book Determination of Handling Qualities and Display Requirements for Helicopter Instrument Flight During Decelerating Approaches to Slow Speeds written by S. Kereliuk and published by . This book was released on 1987 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper discusses the most recent phase of a series of experiments performed jointly by the National Aeronautical Establishment and the United States Federal Aviation Administration. The experiment was aimed at determining the helicopter instrument flight handling qualities requirements when performing steep approaches to low decision heights to a landing area colocated with a Microwave Landing System. A total of 118 approaches were evaluated by three helicopter certification test pilots and one operational/training helicopter pilot. Results indicate that with simple rate damping augmentation in pitch, roll and yaw, and flight director guidance, a Bell 205A-1 exhibited borderline Level 1 (certifiable) handling qualities when performing decelerating approaches to 20 knots to decision heights representative of Category IIIA weather limits. Keywords: Helicopter handling; Instrument flight; (Canada).

Book An Examination of Handling Qualities Criteria for V STOL Aircraft

Download or read book An Examination of Handling Qualities Criteria for V STOL Aircraft written by Seth B. Anderson and published by . This book was released on 1960 with total page 58 pages. 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.
