Abstract
Actuality. The considerable improvement of indexes of efficiency of transport vehicles is ar-rived at by the increase of them aerodynamic descriptions. They substantially influence not only on the dynamics of motion, but also on economic indicators. High efficiency of such transport vehicles, can be grounded by the use of influence of the CRT effect on his aerodynamic descrip-tions and as a result by the increase of aerodynamic quality and indexes of fuel economy. The aim of work is determination of ways of the use of aircraft in ground effect for the improvement of technical parameters of high-speed surface transport vehicles that work on the newest tech-nologies. Scientific novelty experimental studies of aerodynamic descriptions of perspective transport vehicle are Undertaken. The model of a transport vehicle had arrangement with two fuselages. Aerodynamic researches of model were conducted at speeds of appearing suddenly stream a 30 m/s , 40 m/s, 50 m/s. The size of speed pressure was determined after the overfall of static pressure in working chamber of wind-channel and atmosphere. Aerodynamic forces and moments that operate on a model were measured by the sixcomponent scales of АВ-М2. The range of numbers of Reynolds folded from 2106 to 1107 . Practical meaningfulness. Dependenc-es of aerodynamic coefficients are got on the corner of attack and skidding. The analysis of the got dependences is conducted on the corner of attack and skidding.
