This book was released on 2021-11-01 with total page 495 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past eight decades, developments in vertical lift aircraft--both helicopters and vertical/short takeoff and landing (V/STOL) planes--have given the American military unparalleled capabilities on the modern battlefield. The U.S. has led the world in vertical lift technologies with the help of some of the brightest minds in this field--Igor I. Sikorsky, Arthur M. Young, Frank N. Piasecki, Charles H. Kaman and Stanley Hiller, Jr., to name a few--and by having the industrial prowess to make their concepts reality. This book provides a concise historical survey, including technical specifications, drawings, and photographs of every type of helicopter and V/STOL aircraft developed for the U.S. military, from the earliest examples tested in 1941 and 1942, up to the newest prototypes.

Book excerpt: Unlike conventional aviation authors and instructors I do not teach primary flying, crop dusting, pipeline patrol flying, bush flying, helicopter medical evacuation flying, and air to ground gunnery using instruments inside the aircraft as the primary situational awareness tool. Rather I teach Dutch rolls, slow flight and stalls over the runway, the energy management turns, use of ground effect on all takeoffs, the brisk walk apparent rate of closure approach, hover taxi in fixed wing aircraft, and low level low power mountain flying using sights, sounds, smells, and kinetics. Sight is used 99.9% of the time looking at the ground. Airspeed, nor any other instrument is used in takeoff or landing. This text teaches the art of flying in the old style at low level using ground references. Its author has over sixteen thousand hours of flying Army helicopters, crop dusters, and pipeline patrol airplanes at three feet to five hundred feet above ground level.

This book was released on 1966 with total page 179 pages. Available in PDF, EPUB and Kindle. Book excerpt: Introduction: The potential of air transportation as a means of filling the growing need for a mass short haul transportation system was investigated in Ref. 1 where all aspects of short haul air transportation systems were examined in some detail. It was concluded that air transportation could provide a promising means of relieving the congestion associated with the heavy vehicular ground traffic encountered on our urban access routes and at a cost which could well be competitive in the 1970 period with surface transportation systems. This conclusion was postulated on the basis of existing developments in the aircraft industry not yet put into practice on operating airlines but whose feasibility has been well demonstrated with experimental units. Among the many aspects of the total system which must be examined in arriving at such a conclusion are the flight vehicle characteristics. The direct operating costs (DOC) of these vehicles was chosen as a measure of their effectiveness. In short haul operations the direct costs are frequently less important than indirect costs in determining total transportation costs and hence ticket price. However the DOC is a convenient measure for estimating the relative performance of different vehicle configurations and of the penalties associated with operation off optimum conditions. Furthermore, the previous study (Ref. 1) had quantified the almost obvious need in short haul transportation for a vehicle capable of operating from highly congested areas and requiring a minimum in take-off, landing or cleared approach areas. This need directed attention to the newer concepts of vertical take-off and landing (VTOL) aircraft which would not have the speed limitation of present day helicopters, the only VTOL aircraft currently in commercial operations. Because present day experience with these aircraft indicates their direct operating costs to be several times that of comparable fixed wing aircraft, there has been a natural reluctance to predict future operating costs for these vehicles at a level which would make them effective other than in a high-priced specialized operation such as an airline feeder system. Consequently, in Ref. (1), a study of the costs and operating procedures of the existing helicopter airlines was conducted in some depth and by this means the predicted direct operating costs were removed from the realm of discussion and opinion and reduced to a matter of statistics and analysis. Maintenance costs and lost time in air and ground maneuvering were, as expected, important aspects of the cost problem and these were therefore analyzed on a quantitative basis. While there may still be room for disagreement on the predicted DOC for the various vehicles considered in this study, the quantitative information on which these are based have been carefully documented in Ref. (1) and are further substantiated in Ref. (2) for the maintenance aspects and in this report for the vehicle characteristics such as weight, fuel burned and block speeds. This additional documentation has been considered desirable not only to confirm the previous results and to explore other promising configurations, but also to provide a basis for rational discussion of the relative merits and potentials of different vehicle configurations which all too often in the past has been conducted on a subjective rather than an objective basis.-3- It may be well to reiterate the conclusion of Ref. (1) that, in face of the high indirect costs inherent in short haul systems, the actual vehicle configuration is not a dominant factor in determining total operating costs. Any well engineered configuration capable of safe all weather operations would probably prove satisfactory. However the need for direct access to city centers with a minimum of land taking does indicate the desirability of VTOL. These vehicles have the potential for appreciably reducing block times, and hence costs, in the shorter legs, below 50 miles, of interest in intra urban or suburban travel, providing present concepts of control and navigation currently under intensive development for military applications can be reduced to practice in the more legalistic environment of commercial operations.

Book excerpt: When a severe thunderstorm pounces on 26-year-old auto mechanic Willard Custer, corners him in a barn, and then pops the barn's roof in a shocking display of atmospheric power, Willard's life is permanently altered. The banjo-picking son of a West Virginia blacksmith with an unfinished high school education, Willard conceives of a device that will employ the "speed of air" to shorten an aircraft's takeoff and landing (STOL) and, he believes, revolutionize the aircraft industry. This book tells the story of how Custer, charging into a world for which he has no preparation, secures the necessary patents and funding to build four unique aircraft. Then he publicly demonstrates their astonishing STOL and slow-flight capabilities, gaining converts among engineers, pilots, and business leaders. Over four decades, he guides two companies and spawns four others. He engages scientists, manufacturers and pilots in seven American states and Canada. He fights the U.S. Patent and Trademark Office and the Securities and Exchange Commission in court. And he relentlessly solicits the Federal Aviation Administration and Department of Defense, while overcoming corporate double-crossing in Detroit and New York. Described as one of aviation's great what-if stories and a contribution to American folklore, the story of the "father of powered lift" and his Channel Wing Aircraft will inspire readers to trust themselves, to act on their dreams, and to define success in their own terms. Also, in this special edition, aeronautical scientist Robert Englar in his Foreword names Willard Custer the "father of powered lift" by virtue of the precedence and simplicity of his design. Then in his Afterword, Englar describes modern NASA research that enhances the Channel Wing with current technologies and points the way to its ultimate integration into the aviation industry.

This book was released on 2018-07-11 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: Short takeoff and landing (STOL) and advanced short takeoff and vertical landing (STOVL) aircraft are being pursued for deployment near the end of this century. These concepts offer unique capabilities not seen in conventional aircraft: for example, shorter takeoff distances and the ability to operate from damaged runways and remote sites. However, special technology is critical to the development of this unique class of aircraft. Some of the real issues that are associated with these concepts are hot gas ingestion and airframe heating while in ground effects. Over the past nine years, NASA Lewis Research Center has been involved in several cooperative programs in the 9- by 15 Foot Low-Speed Wind Tunnel (LSWT) to establish a database for hot gas ingestion and airframe heating. The modifications are presented that were made in the 9- by 15-Foot LSWT, including the evolution of the ground plane, model support system, and tunnel sidewalls; and flow visualization techniques, instrumentation, test procedures, and test results. The 9- by 15-Foot LSWT tests were conducted at full scale exhaust nozzle pressure ratios. The headwind velocities varied from 8 to 120 kn depending on the concept (STOL or STOVL). Typical compressor-face distortions (pressure and temperature), ground plane contours, and model surface temperature profiles are presented. Johns, Albert L. Glenn Research Center RTOP 505-62-71...

This book was released on 2018-07-10 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: A moving-base simulation has been conducted on the Vertical Motion Simulator at Ames Research Center using a model of an advanced, short takeoff and vertical landing (STOVL) lift fan fighter aircraft. This experiment expanded on investigations during previous simulations with this STOVL configuration with the objective of evaluating (1) control law modifications over the low speed flight envelope, (2) integration of the throttle inceptor with flight control laws that provide direct thrust command for conventional flight, vertical and short takeoff, and flightpath or vertical velocity command for transition, hover, and vertical landing, (3) control mode blending for pitch, roll, yaw, and flightpath control during transition from wing-borne to jet-borne flight, and (4) effects of conformal versus nonconformal presentation of flightpath and pursuit guidance symbology on the out-the-window display for low speed STOVL operations. Assessments were made for takeoff, transition, hover, and landing, including precision hover and landing aboard an LPH-type amphibious assault ship in the presence of winds and rough seas. Results yielded Level 1 pilot ratings for the flightpath and vertical velocity command modes for a range of land-based and shipboard operation and were consistent with previous experience with earlier control laws and displays for this STOVL concept. Control mode blending was performed over speed ranges in accord with the pilot's tasks and with the change of the basic aircraft's characteristics between wing-borne and hover flight. Blending of yaw control from heading command in hover to sideslip command in wing-borne flight performed over a broad speed range helped reduce yaw transients during acceleration through the low speed regime. Although the pilots appreciated conformality of flightpath and guidance symbols with the external scene during the approach, increased sensitivity of the symbols for lateral path tracking elevated the pilots' control activity in...

Available in PDF, EPUB and Kindle. Book excerpt: Distributed electric propulsion (DEP) is an emerging set of technologies which enable new vehicle configurations by allowing the efficient distribution of many smaller propulsors around the airframe. One application of this technology is to greatly enhance the short takeoff and landing (STOL) capability of a fixed-wing aircraft. STOL aircraft may have advantages over vertical takeoff and land (VTOL) configurations being considered for urban passenger transport missions due to lower risk associated with the certification process and improved performance or reduced weight due to smaller required propulsion systems. To be useful for these missions, STOL vehicles require short-field performance competitive with vertical lift configurations. One pathway to achieving this is by placing many electric motors and propellers along the leading edge of the wing, an arrangement referred to as a DEP blown wing. This arrangement increases the effective lift of the wing through interaction of the propeller slipstream with the trailing edge flap. Previous blown wing concepts, based on large propellers or turbine engines, were mechanically complex and adopted only for specialized applications. A DEP blown wing offers a simpler and potentially more efficient way to enhance the high-lift capability of a wing, but the performance is not reliably predictable using existing theoretical or empirical methods. A wind tunnel test of a representative 2D blown wing section was undertaken, and section lift coefficient values up to 9 were measured at moderate power settings. The results of this wind tunnel testing were used to predict the takeoff and landing performance of reference vehicles with wing and power loading representative of modern GA aircraft. The results of this analysis suggest that a DEP blown wing may enable takeoff and landing ground rolls of less than 100 ft. Landing distance over a 50 ft obstacle is identified as the likely driver of runway requirements for a super-short takeoff and landing vehicle.

This book was released on 1983 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: Vertical and short takeoff and landing (V/STOL) aircraft promise new operational capabilities for the Navy. In the past, new vehicle types have been slow in gaining acceptance because of the difficulty in visualizing how these new vehicles should be employed. Once built, experience gained with the vehicle evolved into an operational concept exploiting its best qualities. Now, competition for fiscal resources has reached a level from which it may be difficult to justify the development of any new vehicle without having a well-defined operational concept in hand. This report discusses the use of existing large helicopters to develop operational concepts for V/STOL in naval applications. (Author).

Download or read book VTOL Freewing Proof of Concept Vehicle Development and Testing written by Rachel Marie Axten and published by . This book was released on 2021 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Aircraft capable of vertical take-off and landing (VTOL) have long been important to operations unable to rely on a traditional runway. High power consumption in the hover flight condition has motivated the development VTOL-capable aircraft that can operate in a much more power efficient and higher speed, forward flight mode. Hybrid aircraft, such as the V-22 Osprey, are currently operated to perform high cruise speed missions while retaining the short take-off and landing capabilities. In recent years, unmanned aircraft systems (UAS) have been used to test new hybrid aircraft configurations, such as quadplanes, for their ability to be quickly and cheaply tested and implemented. The freewing aircraft is different from a classic fixed-wing aircraft by a wing that can rotate separate from the fuselage body in pitch. The VTOL freewing configuration is proposed by this work to allow greater pitch authority compared with the tilt-wing configuration and provide greater endurance for a given payload over a helicopter or multirotor configuration. The first main contribution of this work is a freewing dynamic model and adaptive controller implemented in simulation environment. Previous work included development and flight test validation of an adaptive controller used to conduct hover flight with a traditional fixed-wing vehicle. A model of the freewing vehicle was implemented with the previously developed controller and tested against a commanded racetrack at various speeds. Simulated hover and forward flight performance are verified including adequate transition from vertical to forward flight and forward cruise speeds up to 75 fps. The second main contribution of this work is a flight testbed vehicle built for conducting initial hover testing to establish the viability of a longitudinal, rate feedback stability augmentation system with only the wing pitch rate data input and no knowledge of the fuselage pitch attitude. The controller was developed on a ground test rig and evaluated in a series of flight tests of an initial testbed vehicle in hover. Parameter development including hinge placement, electronics set-up, and landing gear height were explored. A second flight testbed vehicle was built with ArduPilot implemented onboard as a tailsitter vehicle configuration to allow for transition between forward and vertical flight. Vertical and initial transition testing was successful with vertical takeoff, landing, and transition up to 45 degs tested. This work motivates future work to integrate the adaptive autopilot onto a testbed vehicle and conduct flight testing to validate parameter impact on longitudinal stability of the wing and fuselage bodies.
