The article is devoted to the topic – interchangeability of parts, components and mechanisms in the vehicle. It provides information on interchangeable parts in tuning old cars, in cars, constructed on the same platform, information about original and non-original spare parts. The possibility of replacement parts from a domestic car is considered by the example of Ford Focus hatchback 2010.

Key words: interchangeable parts, tuning, platform, original spare parts, non-original spare parts

The article proposes a methodological approach based upon the notion that at the stationary approach the probability of element failure in a workable part of the system may be defined by the total density of elements failure probability flows in the system’s part.

The purpose of the article is to compare the possibilities of traditional and proposed methods of calculating the majority and bridged systems failure-free.

The results obtained with proposed approach strictly match the systems failure conditions. The approach appropriateness is confirmed by the results of experimental research. The methods proposed in the article may be used in calculating the failure-free of the aircraft and spacecraft functional systems.

Key words: majority system, complicated system, failure probability, elements failure flow density, failure discreteness.

The article presents approaches to designing a WIG vehicle with specified maneuvering characteristics and a wide operating speed range for level flight. Providing the maneuverability mounts challenges to operational range of angles of attack and lift coefficients. The aerodynamic design of a WIG vehicle meeting the requirements is proposed.

Key words: a WIG vehicle; maneuverability; a lift coefficient; aerodynamic design.

The article presents the main assessment results of calculating reliability of aerodynamic characteristics of a support system near the underlying surface. The assessment is based on comparing the calculation results with the experimental data and the results obtained by other authors using alternative methods.

Key words: aerodynamic characteristics; a WIG vehicle.
