Available in PDF, EPUB and Kindle. Book excerpt: This report is intended for use as a collection and analysis of diverse data gathering, empirical, and analytical approaches to the high angle of attack aircraft stability and control problem; as a compendium of several methods of defining aircraft departure and spin susceptibility; as a reference for spin definition and spin recovery enhancement; as a review of specifications, regulations, and design guides as they pertain to high angle of attack flight; and as a medium for expounding where tomorrow's high angle of attack investigative attention should focus. The design of safe, effective fighter aircraft in the high angle of attack combat environment is reaching a critical point. Accepted flying qualities design guidelines (necessary to establish stability and control requirements) must be established to address flight operations in the high angle of attack flight regime. Most of the research to date has focused on aircraft departure. Parameters/criteria to define desired high angle of attack flying qualities in the post-stall region (outside the realm of departure) are still unanswered.

This book was released on 1974 with total page 146 pages. Available in PDF, EPUB and Kindle. Book excerpt: An investigation of handling qualities in stall-departure flight regimes has been conducted. The study involved key parameter identification, systems analysis and piloted simulation. The technical results and conclusions are detailed in Vol. I. This second volume contains support data in the form of appendices. These include equations of motion and the A-7 high angle of attack aerodynamic data used in the nonlinear six-degree-of-freedom digital simulation. It also contains stability derivatives and transfer functions evaluated at specific flight conditions near stall. The five-degree-of-freedom piloted simulation (analog) is described in detail.

Available in PDF, EPUB and Kindle. Book excerpt: From the designer to the pilot, everyone associated with the flying qualities of high performance military aircraft, particularly the fighter or attack variety, is or should be aware of the importance of the high angle of attack flight regime. It is here that the aircraft will spend a significant amount of its time when performing the mission for which it was designed. It is here that the aircraft must display its most outstanding performance. It is also here that the aircraft, when pushed beyond its limits of controllability, can seemingly defy all laws of physics and principles of flight with which its surprised and often bewildered pilot is acquainted. The frequency of inadvertent loss of control at high angle of attack is such that many combat aircraft pilots are becoming firmly convinced that all pilots may be divided into two categories: those who have departed controlled flight, and those who will. Most thoroughly convinced are those pilots who fall into the former category. The unfortunate fact concerning departure from controlled flight at high angle of attack is that many aircraft and pilots are lost each year due to failure to recover from the out-of-control flight condition. The circumstances surrounding the losses are varied. Departures from controlled flight may occur unintentionally during high-g maneuvers or intentionally during a nose-high deceleration to zero airspeed in an attempt to gain an advantage over an opponent in combat maneuvering; the aircraft may spin and the gyration be identified too late for recovery or a steep spiral may be mistakenly identified as a spin, causing recovery controls to be misapplied. Whatever the circumstances, departures from controlled flight result all too often in catastrophe. For this reason, test pilots in particular must be familiar with every facet of the high angle-of-attack flight regime.

This book was released on 1974 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: Attention has been focused on departure (e.g., nose slice, wing rock) and recovery of military aircraft as opposed to spin entry. The approach has been to analytically identify and validate key flying quality parameters, to qualitatively assess and verify these through piloted simulation, and to measure and quantify effects on key dynamic parameters of pilot describing functions.

Available in PDF, EPUB and Kindle. Book excerpt: High-performance aircraft are susceptible to degraded flying qualities during maneuvering flight for a number of reasons, including aerodynamic nonlinearities, inertial coupling, and rapidly changing flight condition. Lateral-directional modes of motion coupled with longitudinal motions in asymmetric flight and high angle of attack can lead to instability and adverse control response. The pilot must adapt his control strategies to varying aircraft dynamics, and his work load is high; consequently, improper piloting procedures could occur, leading to inadvertent loss of control.

Book excerpt: This program was conducted to evaluate the X-29 configuration at high angle of attack. The flight test objectives were to evaluate the high angle of attack (AOA) flying qualities and to conduct a limited military utility and agility metric test effort with the X-29 number two research aircraft (USAF S/N 820049). These objectives were met. The X-29 was an advanced technology demonstrator aircraft which incorporated a forward swept wing, a thin supercritical airfoil, an aeroelastically tailored composite wing cover, full span flaperons providing variable camber, variable incidence close coupled canards, high longitudinal static instability, a three surface longitudinal control configuration, and a triplex digital flight control system.

Available in PDF, EPUB and Kindle. Book excerpt: The second edition of Flight Stability and Automatic Control presents an organized introduction to the useful and relevant topics necessary for a flight stability and controls course. Not only is this text presented at the appropriate mathematical level, it also features standard terminology and nomenclature, along with expanded coverage of classical control theory, autopilot designs, and modern control theory. Through the use of extensive examples, problems, and historical notes, author Robert Nelson develops a concise and vital text for aircraft flight stability and control or flight dynamics courses.

Download or read book Aircraft Maneuvers for the Evaluation of Flying Qualities and Agility written by David J. Wilson and published by . This book was released on 1993 with total page 98 pages. Available in PDF, EPUB and Kindle. Book excerpt: A set of aircraft maneuvers has been developed to augment evaluation maneuvers used currently by the flying qualities and flight test communities. These maneuvers extend evaluation to full aircraft dynamics throughout the aircraft flight envelope. As a result, a tie has been established between operational use and design parameters without losing control of the aircraft evaluation process. Twenty maneuvers are described as an initial set to examine primarily high-angle-of attack conditions. Perhaps as important as the maneuvers themselves is the method used to select them. These maneuvers will allow direct measurement of flying qualities throughout the flight envelope instead of merely comparing parameters to specification values.
