This book was released on 1944 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tests with a dynamically similar model of the army A-20A airplane were made to determine the best way to land the airplane in calm and rough water and to determine its probable ditching performance. The behavior was studied by making visual operations, by recording longitudinal decelerations, and by taking motion pictures of the landings.

Book excerpt: Tests were conducted to determine the best way to ditch the Army B-24 airplane in calm and rough water and to determine its probable ditching performance. A dynamically similar mode of the B-24 airplane was ditched in calm water in tank no. 2 and in calm and rough water from an outdoor catapult. Its behavior was ascertained by making visual observations, by recording maximum decelerations, and by taking motion-picture records of the landings.

Available in PDF, EPUB and Kindle. Book excerpt: The tests reported herein are the first in a series of tests requested by the Army Air Forces to determine the behavior of landplanes when they are forced to land on the water. (The emergency landing of a landplane on water is called "ditching.") The tests are being made in NACA tank no. 2 with scale dynamic models (models having scale weight and scale moment of inertia about all axes).

This book was released on 2013-07 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tests of a 1/20-scale dynamically similar model of the Northrop B-35 airplane were made to study its ditching characteristics. The model was ditched in calm water at the Langley tank no. 2 monorail. Various landing attitudes, speeds, and conditions of damage were simulated during the investigation. The ditching characteristics were determined by visual observation and from motion-picture records and time-history acceleration records. Both longitudinal and lateral accelerations were measured. Results are given in tabular form and time-history acceleration curves and sequence photographs are presented. Conclusions based on the model investigation are as follows: 1. The best ditching of the B-35 airplane probably can be made by contacting the water in a near normal landing attitude of about 9 deg with the landing flaps full down so as to have a low horizontal speed. 2. The airplane usually will turn or yaw but the motion will not be violent. The maximum lateral acceleration will be about 2g. 3. If the airplane does not turn or yaw immediately after landing, it probably will trim up and then make a smooth run or porpoise slightly. The maximum longitudinal decelerations that will be encountered are about 6g or 7g. 4. Although the decelerations are not indicated to be especially large, the construction of the airplane is such that extensive damage is to be expected, and it probably will be difficult to find ditching stations where crew members can adequately brace themselves and be reasonably sure of avoiding a large inrush of water

This book was released on 2013-07 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ditching characteristics of the Lockheed XR60-1 airplane were determined by tests of a 1/24-scale dynamic model in calm water at the Langley tank no. 2 monorail. Various landing attitudes, flap settings, speeds, and conditions of damager were investigated. The ditching behavior was evaluated from recordings of decelerations, length of runs, and motions of the model. Scale-strength bottoms and simulated crumpled bottoms were used to reproduce probable damage to the fuselage. It was concluded that the airplane should be ditched at a landing attitude of about 5 deg with flaps full down. At this attitude, the maximum longitudinal deceleration should not exceed 2g and the landing run will be bout three fuselage lengths. Damage to the fuselage will not be excessive and will be greatest near the point of initial contact with the water.

This book was released on 2006-01-09 with total page 490 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hydrodynamics of High-Speed Marine Vehicles, first published in 2006, discusses the three main categories of high-speed marine vehicles - vessels supported by submerged hulls, air cushions or foils. The wave environment, resistance, propulsion, seakeeping, sea loads and manoeuvring are extensively covered based on rational and simplified methods. Links to automatic control and structural mechanics are emphasized. A detailed description of waterjet propulsion is given and the effect of water depth on wash, resistance, sinkage and trim is discussed. Chapter topics include resistance and wash; slamming; air cushion-supported vessels, including a detailed discussion of wave-excited resonant oscillations in air cushion; and hydrofoil vessels. The book contains numerous illustrations, examples and exercises.

Henry H. “Hap.” Arnold and published by Pickle Partners Publishing. This book was released on 2015-11-06 with total page 927 pages. Available in PDF, EPUB and Kindle. Book excerpt: Includes the Aerial Warfare In Europe During World War II illustrations pack with over 180 maps, plans, and photos. Gen Henry H. “Hap.” Arnold, US Army Air Forces (AAF) Chief of Staff during World War II, maintained diaries for his several journeys to various meetings and conferences throughout the conflict. Volume 1 introduces Hap Arnold, the setting for five of his journeys, the diaries he kept, and evaluations of those journeys and their consequences. General Arnold’s travels brought him into strategy meetings and personal conversations with virtually all leaders of Allied forces as well as many AAF troops around the world. He recorded his impressions, feelings, and expectations in his diaries. Maj Gen John W. Huston, USAF, retired, has captured the essence of Henry H. Hap Arnold—the man, the officer, the AAF chief, and his mission. Volume 2 encompasses General Arnold’s final seven journeys and the diaries he kept therein.
