This text and CD-ROM is dedicated to the problem of flight control over the sea at low altitudes, and is concerned particularly with Ekranoplanes: a breed of aircraft which use low resistance of ground effect flight. Under low flying conditions radar sensors measuring altitude, tilt and velocity of craft trace the variable profile of wave disturbance practically without averaging, thus making it difficult to gauge the motion parameters in relation to the undisturbed level of the sea surface. Translated from the original Russian, this volume should be of interest to specialists in aviation and marine instrumentation, and to researchers and designers of control systems for ekranoplanes, hovercraft, hydrofoils and other types of transport designed for motion close to the sea. A video on CD-ROM showing various versions of the Ekranoplane in flight and general operation is included.
This kit contains 12 full colour pop-out paper pieces, a catapult launcher and instruction booklet. These awesome high-performance planes are frustration-freeâ€”no glue needed, just a stapler and some imagination. The full-colour instruction book inside the kit provides clear, step-by-step folding instructions for each plane.
Ever since the earliest days of the great conquest of the air, first by the dirigible balloon and then by the aeroplane, their use in time of war has been a fruitful theme for discussion. But their arrival was of too recent a date, their many utilities too unexplored to provide anything other than theories, many obviously untenable, others avowedly problematical. Yet the part airships have played in the Greatest War has come as a surprise even to their most convinced advocates. For every expectation shattered, they have shown a more than compensating possibility of usefulness. In this volume an endeavour has been made to record their achievements, under the stern test of trial, as an axiom of war, and to explain, in untechnical language, the many services to which they have been and may be applied.
