Book Synopsis AH-1G Lateral Flight Performance Test by : Leslie J. Hepler
Download or read book AH-1G Lateral Flight Performance Test written by Leslie J. Hepler and published by . This book was released on 1972 with total page 21 pages. Available in PDF, EPUB and Kindle. Book excerpt: The lateral flight performance of the tractor-tail-rotor-configured AH-1G helicopter was evaluated at gross weights of 8500 and 9500 pounds. The AH-1G is capable of 0.53g and 0.38g accelerations in right and left lateral flight, respectively, at 8500 pounds. At a 9500-pound gross weight, acceleration was 0.23g to the right and 0.20g to the left. Aircraft handling qualitites and time required to attain maximum lateral velocity are dependent upon rate and type of control application. A step-type lateral control input permitted rapid attainment of accelerating attitude but produced yaw oscillations which resulted in loss of directional control and caused high pilot workload in stabilizing power and aircraft attitude. Ramp inputs delayed establishment of the accelerating attitude. A modified pulse input induced negligible roll and yaw oscillation and produced rapid establishment of the desired roll attitude. Direction-of-flight reversals induced large power transients that frequently exceeded the transmission torque limits. Precise heading and pitch attitude could not be maintained during the reversals. Airspeed in lateral flight could not be determined without special airspeed measuring devices. The sideward airspeed limit was exceeded frequently in left lateral flight with no warning or cue to the pilot that the limit had been reached.

Book Synopsis Engineering Flight Test of the Ah-1g Helicopter (hueycobra). Phase B by : John R. Melton
Download or read book Engineering Flight Test of the Ah-1g Helicopter (hueycobra). Phase B written by John R. Melton and published by . This book was released on 1968 with total page 110 pages. Available in PDF, EPUB and Kindle. Book excerpt: Part 1 of the AH-1G helicopter Phase B test was conducted at Ft Hood, Texas by the US Army Aviation Test Activity, Edwards AFB, California. The helicopter flying qualities were evaluated throughout the aircraft speed range for the Scout and Hog configurations at a mid-center-of-gravity location. Flying qualities were also evaluated during weapons firing and external stores jettison. The primary deficiencies detected during this test were stability and Control augmentation system (SCAS)-pylon coupling, inadequate in-ground-effect (IGE) directional control power, undue pilot attention required to avoid exceeding the torque limits of the helicopter transmission in dives and left rolls with fixed collective, and an inadequate, illogical fire control system. Other shortcomings were detected, such as airspeed system errors, degradation of flying qualities with SCAS off, static lateral cyclic control force imbalance, and marginal cockpit ventilation. Helicopter reactions to weapons firing and external stores jettison were satisfactory, and the contractor approved flight envelope for firing and jettison was acceptable.

Download or read book Introduction to Flight Testing written by James W. Gregory and published by John Wiley & Sons. This book was released on 2021-05-19 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: Introduction to Flight Testing Introduction to Flight Testing Provides an introduction to the basic flight testing methods employed on general aviation aircraft and unmanned aerial vehicles Introduction to Flight Testing provides a concise introduction to the basic flight testing methods employed on general aviation aircraft and unmanned aerial vehicles for courses in aeronautical engineering. There is particular emphasis on the use of modern on-board instruments and inexpensive, off-the-shelf portable devices that make flight testing accessible to nearly any student. This text presents a clear articulation of standard methods for measuring aircraft performance characteristics. Topics covered include aircraft and instruments, digital data acquisition techniques, flight test planning, the standard atmosphere, uncertainty analysis, level flight performance, airspeed calibration, stall, climb and glide, take-off and landing, level turn, static and dynamic longitudinal stability, lateral-directional stability, and flight testing of unmanned aircraft systems. Unique to this book is a detailed discussion of digital data acquisition (DAQ) techniques, which are an integral part of modern flight test programs. This treatment includes discussion of the analog-to-digital conversion, sample rate, aliasing, and filtering. These critical details provide the flight test engineer with the insight needed to understand the capabilities and limitations of digital DAQ. Key features: Provides an introduction to the basic flight testing methods and instrumentation employed on general aviation aircraft and unmanned aerial vehicles. Includes examples of flight testing on general aviation aircraft such as Cirrus, Diamond, and Cessna aircraft, along with unmanned aircraft vehicles. Suitable for courses on Aircraft Flight Test Engineering. Introduction to Flight Testing provides resources and guidance for practitioners in the rapidly-developing field of drone performance flight test and the general aviation flight test community.

Book Synopsis Recent Progress in Flow Control for Practical Flows by : Piotr Doerffer
Download or read book Recent Progress in Flow Control for Practical Flows written by Piotr Doerffer and published by Springer. This book was released on 2017-05-11 with total page 505 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book explores the outcomes on flow control research activities carried out within the framework of two EU-funded projects focused on training-through-research of Marie Sklodowska-Curie doctoral students. The main goal of the projects described in this monograph is to assess the potential of the passive- and active-flow control methods for reduction of fuel consumption by a helicopter. The research scope encompasses the fields of structural dynamics, fluid flow dynamics, and actuators with control. Research featured in this volume demonstrates an experimental and numerical approach with a strong emphasis on the verification and validation of numerical models. The book is ideal for engineers, students, and researchers interested in the multidisciplinary field of flow control.
