Abstract
Arbitrary flange connection with metal seal, which has one or more wedge-shaped edges in its construction, is estimated in the article irrespectively of construction of flange connection and its parts. Raised question is about obtaining a method for choosing the optimal wedge angle according to the criterion of minimal leak of the sealed substance through the contact of the wedge-shaped edge of the seal with the flange. The scientific problem is solved by means of derivation and exploration of the permeability function of the contact of the wedge-shaped edge of the seal with the flange a function, showing the dependence of the leak of the sealed substance in conditional flow units on the angle of the wedge-shaped edge. Results of the research make it possible to increase the tightness of flange connections, mentioned before, without increasing of tightening force, and, as a result, without increasing of the mass of flange connection, and this is especially important in modern flying vehicles.
