FIELD: aircraft engine construction, operations for milling inter-blade passages of impellers or mono-wheels of gas turbine engines.
SUBSTANCE: method comprises steps of milling inter-blade passages; milling back and saddle of blade and recess between them. In order to lower labor consumption of manufacturing process, inter-blade passages to be milled are marked with numbers and they are milled alternatively next but one. Alloy is poured to milled passages and then adjacent inter-blade passages are milled. After such procedure alloy is removed by melting out. It is possible to pour Wood's alloy into milled inter-blade passages.
EFFECT: reduced labor consumption of manufacturing method.
