Wing-In-Ground Effect Flight Control: New Role of Automatic Systems
نویسنده
چکیده
A trouble-free flight at low altitude over the disturbed sea surface and also marine landing requires the application of the special methods and means of motion control which are capable to solve the corresponding specific problems. Methods of stability provision and solving some other problems of WIG flight by means of automatic control are analyzed. The requirements for motion control systems are reviewed and the criteria for their improvement are given. The statement of the main problems of equipment and software design for flight control at small altitude above the disturbed surface is performed. The aim of investigation is to define the way for operational performance improvement of the vehicles of advanced design. A promising way is by implementation of modern navigation and motion control systems. The experience and achievements in this field of high technology are described. Probable areas of the most effective application of vehicles with such equipment are indicated.

متن کاملInduced Drag Savings from Ground Effect and Formation Flight in Brown Pelicans
Cine films of brown pelicans flying in formation were used to measure altitudes and wing tip spacing (WTS, distance perpendicular to the flight path between wing tips of adjacent birds at maximum span) for birds flying in ground effect, and vertical displacements and WTS for birds flying out of ground effect. Views were near coplanar with the plane of flight paths, and maximum wing span was use...

The purpose of this paper is to present a fast, economical and practical method for mathematical modeling of aerodynamic characteristics of rectangular wing-in-ground effect (WIG). Reynolds averaged Navier-Stokes (RANS) equations were converted to Bernoulli equation by reasonable assumptions. Also Helmbold's equation was developed for calculation of the slope of wing lift coefficient in ground ...
