Special forms of flight. I: Balloons, gliders, and hang gliders.
Two hundred years ago the Montgolfier brothers first demonstrated to the world that man-carrying "engines for flying" were possible. Their vehicle, however, did not have "artificiall Wings" but was a balloon filled with hot air. (A Brazilian, Bartolomeu de Gusmao, had flown a small unmanned hot air balloon 74 years earlier.') After successful unmanned demonstrations the first recorded free flig...
متن کاملGliders in Rule 110
The existence of several periodic structures (known as gliders) in the evolution space of the one-dimensional cellular automaton Rule 110, has important lines of investigation in cellular automata theory such as: complex behavior, universal computation and self-reproduction. We investigate the types of gliders, their properties and production through collisions in Rule 110 and their representat...
متن کاملthe effect of taftan pozzolan on the compressive strength of concrete in the environmental conditions of oman sea (chabahar port)
cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
A Practical Method for Investigation of Aerodynamic and Longitudinal Static Stability of Wing-in-Ground Effect
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 ...
متن کاملRouting strategies for underwater gliders
rapidly reach a specified waypoint or to maximize the ability to map a measured field, both in the presence of significant currents. For rapid transit in a frozen velocity field, direct minimization of travel time provides a trajectory ‘‘ray’’ equation. A simpler routing algorithm that requires less information is also discussed. Two approaches are developed to maximize the mapping ability, as ...
