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 1965 with total page 49 pages. Available in PDF, EPUB and Kindle. Book excerpt: The results of a flight research program to evaluate the effects of certain lateral-directional handling qualities are reported and discussed. The evaluation program was designed to assess the acceptability of variations in Dutch roll dynamics and aileron-yaw coupling for the low speed landing approach task. The effects of a reduction in static directional stability on the high Mach number cruise task were also evaluated. A variable stability T-33 was used for conducting these evaluations. Thirty-three different sets of low speed, and fifteen different sets of high speed lateral-directional handling qualities were evaluated by an experimental test pilot. The evaluation pilot comments and a numerical rating were given for each configuration as to its suitability for the mission or task involved. Identification of the stability parameters from in-flight records was made using airplane rudder doublet responses and the Equations-of-motion Technique. An analysis was made of the pilot ratings and pilot comments, and these in turn were correlated with the lateral-directional stability parameters measured. (Author).

Download or read book Evaluation of Lateral-directional Handling Qualities of Piloted Re-entry Vehicles Utilizing Fixed-base and In-flight Evaluations written by J. I. Meeker and published by . This book was released on 1967 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: Three different groups of lateral-directional flight characteristics were investigated and the results are presented in three parts. Part I evaluation configurations were selected from a previous re-entry vehicle evaluation program; Part II configurations were based on a general lateral-directional handling qualities investigation; and Part III configurations were directly applicable to lifting body investigations. All of the configurations were evaluated for their suitability to the re-entry mission. The vehicle used for both the fixed-base and in-flight simulations was a three-axis variable stability T-33 airplane. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: Proceedings are reported of a symposium held in Dayton, sponsored by the Flight Dynamics Laboratory during 2-5 March 1982. The symposium was planned and ran by the Flight Control Division, specifically the Flying Qualities Group and the Control Techniques Group as part of an ongoing effort to revise and upgrade both MIL-F-8785C, Military Specification, Flying Qualities of Piloted Airplanes, and MIL-F-9490D, Flight Control System-Design, Installation and Test of Piloted Aircraft, General Specification For. Specialists from both the flying qualities and flight control system disciplines were gathered in Dayton from both industry and government agencies. Formal and informal presentations, plus workshop discussions, were structured around proposed draft versions of the new Flying Qualities MIL-Standard and Handbook and the new Flight Control Systems MIL-Specification and Handbook. This report contains a record of the presentations and discussions as submitted by the individual authors.

Available in PDF, EPUB and Kindle. Book excerpt: This report is a codification in two parts of conventional aircraft handling qualities criteria. The results of this effort are to serve as an intermediate design guide in the areas of lateral-directional oscillatory and roll control. The roll handling qualities portion of this report uses as a point of departure the concept that control of bank angle is the primary piloting task in maintaining or changing heading. In the lateral oscillatory portion of this effort, in defining requirements for satisfactory Dutch roll characteristics, a fundamental consideration is the fact that the motions characterizing this mode are ordinarily not the pilot's chief objective. That is, he is not deliberately inducing Dutch roll motions in the sense that he induces rolling and longitudinal short-period motions. A worthwhile approach to establishment of Dutch roll damping requirements is to first establish the basic level, and then to study the varied influences of the disturbance parameters. This approach provides the basis for the material contained in this report.

This book was released on 1964 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: Longitudinal and lateral directional flying qualities for the re-entry mission are reported. The program utilized primarily a high-fidelity fixed-base ground simulator with evaluations made by three pilots. One of the three pilots also made in-flight evaluations of longitudinal flying qualities in the same vehicle, a threeaxis variable stability airplane flown with a two-axis side controller and conventional rubber pedals. Control sensitivity evaluations were compared to center stick results of earlier work. The longitudinal flying qualities as evaluated both on the ground simulator and in flight are compared and related to earlier investigations. Pilot rating variability, both interpilot and intrapilot, are quantized and discussed for the ground and flight experiments. Performance measures are reported.

Available in PDF, EPUB and Kindle. Book excerpt: The report uses as a point of departure the concept that control of bank angle is the primary piloting task in maintaining or changing heading. Regulation of the bank angle to maintain heading is a close-loop tracking task in which the pilot applies aileron control as a function of observed bank angle error. For large heading changes, the steady-state bank angle consistent with available or desired load factor is attained in an open-loop fashion; it is then regulated in a closed-loop fashion throughout the remainder of the turn. For the transient entry and exit from the turn, the pilot is not concerned with bank angle per se, but rather with attaining a mentally commanded bank angle with tolerable accuracy in a reasonable time, and with an easily learned and comfortable program of aileron movements.

Available in PDF, EPUB and Kindle. Book excerpt: This in-flight simulation experiment, using the USAF NT-33 vairable stability aircraft operated by Calspan, was undertaken to generate lateral-directional flying qualities data applicable to highly augmented fighter aircraft. In particular, the effects of time delay and prefilter lag in the lateral flight control system were studied for representative Flight Phase Category A and C tasks. The combined effects of these elements as well as the effects of nonlinear command gain and high Dutch roll damping were also evaluated. Tasks included were actual target tracking, air refueling and precision landing as well as special Head-Up Display (HUD) tracking tasks. Results indicated a properly designed HUD bank angle tracking task is a valid flying qualities evaluation task. Data show that lateral flying qualities are very sensitive to control system time delay and very short values of roll mode time constant typically result in poor lateral flying qualities. Excellent separation of the data into flying qualities levels is achieved for the Category A task data using time domain equivalent systems parameters. An optimum equivalent time constant value of 0.5 sec is indicated by the data; sensitivity to equivalent time delay is a minimum at this value. Volume I contains the body of the report, while Volume II consists of the Appendices.
