Abstract
The relevance of the task of replenishing the arsenal of means for measuring air parameters of aircraft movement relative to the surrounding air environment is noted. These means should be characterized by a simple design, low weight and cost, the possibility of use on small-sized and ultra-light aircraft, manned, unmanned and remotely piloted aircraft of the aircraft configuration. The advantages of the system for measuring the air parameters of aircraft movement relative to the environment with one integrated non-protruding fuselage receiver of the incident air flow, with built-in converters of primary information parameters into electrical signals and a built-in computer that generates the output digital signals of the system are indicated. The relevance of studying the instrumental and methodological errors of the system channels is noted. Analytical models of instrumental errors of the system channels for measuring airborne parameters of aircraft movement with an integrated fuselage flow receiver are developed, allowing one to study the influence of errors of functional elements on the instrumental error of the measuring channels of the system and to select the element base of the system. Analytical models are obtained, an assessment is made of the methodological errors of the channels of the system for measuring the air parameters of aircraft movement with an integrated fuselage flow receiver, caused by the distortion of the incoming air flow at the installation site of the flow receiver during aircraft movement and flow around the fuselage, and a direction for reducing the methodological errors of the system channels is indicated.
