SOME RESULTS OF EXPERIMENTAL RESEARCH OF AERODYNAMIC CHARACTERISTICS OF COMPONENTS OF A CARRIER SYSTEM OF AN AIRCRAFT
Abstract
Despite active development of methods of theoretical aerohydrodynamics, construction of the increasingly sophisticated mathematical models, and construction of correct methods for their numerical aerodynamics, the creators of new aircraft models still in many cases prefer reliable results of experimental research, despite the high cost and laboriousness. Exactly because the most perfect modern mathematical models describing the multivariable processes of co-operation of the real environment with the streamlined object, not to a full degree able to describe all concomitant effects. The results of systematic experimental researches of major aerodynamic descriptions of the elements of the bearing systems are presented such as a carrying capacity, force of resistance, and also moments of corporal profiles and wings of eventual scope of free-form in a plan and spatial configuration. Experimental researches were conducted in the attested wind-channels of the National aerospace university the name of N. Ye. Zhukovski " KHAI" at the parameters of similarity: degree of turbulence and number of Reynolds., corresponding to the external of a transport aviation environments. Weighing tests were carried out using the tested sixcomponent aerodynamic weights Substantial influence of form of wing is shown in a plan, his spatial configuration, and presence of mechanization both mechanical and power on basic aerodynamic descriptions of the bearing systems. The results of these experimental researches widely are highly sought in the processes of planning of wide spectrum of aircrafts, using the effect of carrying capacity both at the cruiser mode of flight and at maneuverings with the assured safe external environments. There is present experimental equipment, and also treatment of results of tests software real-time, not only total aerodynamic descriptions allow to get but, for example, such as hydrostatical pressure, also up-diffused, especially highly sought in the processes of прочностных calculations of elements of the bearing systems. Job performances can be used in the educational process of preparation of specialists of industry of higher qualification.
