This book was released on 1963 with total page 174 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study is directed toward investigating the effects on pilots rating of large variations (L alpha) in the relative amplitude and phase of the basic airplane responses to elevator control. The effects of L alpha and true speed on longitudinal flying qualities, optimum control gain, and normal acceleration response to turbulence were investigated in a ground simulator. The steady state ratio of normal acceleration to angle of attack was found to be of significance both to the flying qualities of an airplane and to the optimum longitudinal control gain. Normal acceleration response to rough air was demonstrated to be primarily a function of L alpha and the short period frequency and damping ratio.

Book Synopsis Fixed-base and In-flight Simulations of Longitudinal and Lateral-directional Handling Qualities for Piloted Re-entry Vehicles by : Edwin A. Kidd
Download or read book Fixed-base and In-flight Simulations of Longitudinal and Lateral-directional Handling Qualities for Piloted Re-entry Vehicles written by Edwin A. Kidd and published by . 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: Simulation techniques are applied to the problems of determining aircraft handling qualities. Analog computers, fixed-base simulators, and various other ground machines are discussed. In particular, the theory and actual techniques of in-flight simulators of the variable-stability type are considered. The conclusion is drawn that the solution of the various problems of handling-qualities requirements and of control systems development requires the use of ground-based simulators and in-flight simulators as complementary tools.

Download or read book Simulator Study of Minimum Acceptable Level of Longitudinal Stability for a Representative STOL Configuration During Landing Approach written by William D. Grantham and published by . This book was released on 1974 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: A fixed-base simulator study was conducted to determine the minimum acceptable level of longitudinal stability for a representative turbofan STOL (short take-off and landing) transport airplane during the landing approach. Real-time digital simulation techniques were used. The computer was programed with equations of motion for six degrees of freedom, and the aerodynamic inputs were based on measured wind-tunnel data. The primary piloting task was an instrument approach to a breakout at a 60-m (200-ft) ceiling.

Book Synopsis Theoretical and Experimental Investigation of Some New Longitudinal Handling Qualities Parameters by : Henry R. Jex
Download or read book Theoretical and Experimental Investigation of Some New Longitudinal Handling Qualities Parameters written by Henry R. Jex and published by . This book was released on 1962 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: The systems-analysis theory of handling qualities (which describes the pilot's adaptive behavior in closed-loop operation by servo techniques, and relates his opinion-ratings to his adapted characteristics and the system performance) is used to reveal some important parameters associated with the numerator terms in the airframe longitudinal transfer function. The predictions are verified by five experienced test pilots operating in a fixed-base aircraft simulator. Four possible numerator effects on handling qualities are analyzed theoretically: short-period lead effect on pitch attitude tracking, static-to-short-period gain effects on attitude tracking, short-period lead effects on the control of short-period divergence, and numerator frequency and damping effects on altitude tracking. The results are correlated with other test work, and the implications of these results on future handling qualities research and specifications are discussed.
Book Synopsis A Piloted Simulator Investigation of Ground Effect on the Landing Maneuver of a Large, Tailless, Delta-wing Airplane by : C. Thomas Snyder
Download or read book A Piloted Simulator Investigation of Ground Effect on the Landing Maneuver of a Large, Tailless, Delta-wing Airplane written by C. Thomas Snyder and published by . This book was released on 1970 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: The influence of ground effect on the landing flare characteristics of a supersonic transport airplane (SST) was investigated in a fixed cockpit simulator. Simulations of an ogee-modified delta-wing F5D-1 airplane and a subsonic jet transport were used for evaluating the simulator and as a reference configurations during landing comparisons. Dynamic responses of the SST to seven different ground-effect models during controls-fixed and constant-attitude descents are also presented, followed by piloted subjective assessments. A summary of ground effects on delta-like wings is included in the appendixes.
Book Synopsis Motion Cue and Simulation Fidelity Aspects of the Validation of a General Purpose Airborne Simulator by : Kenneth J. Szalai
Download or read book Motion Cue and Simulation Fidelity Aspects of the Validation of a General Purpose Airborne Simulator written by Kenneth J. Szalai and published by . This book was released on 1971 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the validation of the general purpose airborne simulator, certain motion and visual cues could not be duplicated because the airborne simulator could not be independently controlled in six degrees of freedom. According to pilot opinion (NASA TN D-6431), however, the XB-70 airplane at two flight conditions had been simulated satisfactorily. Because of the dependence of simulation results on simulator configuration, two areas were investigated after the validation program was completed. The first was the effect of mismatched cues on observed handling qualities. Experiments which varied lateral acceleration at the pilot's location and yaw rate, while keeping constant the lateral-directional dynamics displayed on the pilot's instruments, showed pilot sensitivity to directional motion cues to be different for the simulation of two XB-70 flight conditions. A technique for allowing consecutive evaluations of moving- and fixed-base configurations in flight was used successfully to determine motion cue effects. The second area investigated was the measurement and description of simulation fidelity. In-flight frequency-response measurements of the model-following system were taken to examine model-following fidelity for directly matched variables such as sideslip and roll rate as well as uncontrolled parameters such as lateral acceleration.
Book Synopsis Simulation Study of Impact of Aeroelastic Characteristics on Flying Qualities of a High Speed Civil Transport by : David L. Raney
Download or read book Simulation Study of Impact of Aeroelastic Characteristics on Flying Qualities of a High Speed Civil Transport written by David L. Raney and published by . This book was released on 2002 with total page 98 pages. Available in PDF, EPUB and Kindle. Book excerpt: A piloted simulation study conducted in NASA Langley Visual Motion Simulator addressed the impact of dynamic aero- servoelastic effects on flying qualities of a High Speed Civil Transport. The intent was to determine effectiveness of measures to reduce the impact of aircraft flexibility on piloting tasks. Potential solutions examined were increasing frequency of elastic modes through structural stiffening, increasing damping of elastic modes through active control, elimination of control effector excitation of the lowest frequency elastic modes, and elimination of visual cues associated with elastic modes. Six test pilots evaluated and performed simulated maneuver tasks, encountering incidents wherein cockpit vibrations due to elastic modes fed back into the control stick through involuntary vibrations of the pilots upper body and arm.
