Comparative tests of the bench equipment for test of gas-turbine engines

Abstract

In the article questions of comparative tests of gas-turbine engines are considered. The problem consists in appreciable difference in a gas-turbine engine testing results on different testing benches. The method of interlaboratory (interstand) comparative research has been suggested to use for collation of measurers and control tools precision. At the same time this method is capable of defining relative characteristics of gas turbine engines and their degree of similarity to working conditions. Having applied this method it can provide the support of measuring results traceability at testing benches of different enterprises, improvement of quality and safety of the aircraft equipment is result of this approach.
