Abstract
A method for manufacturing a dual-structured aircraft engine starting and generating apparatus is provided. The method includes printing a housing using a three-dimensional printing process including a main machine portion and an exciter portion for receiving at least part of a generator system. Printing the housing includes printing a cooling jacket portion comprising one or more cooling passages that is a monolithic part of a sidewall of the housing.
Claims20
A method for manufacturing a dual-structured aircraft engine starting and generating apparatus, the method comprising:
- using a three-dimensional printing process, printing a housing including a main machine portion and an exciter portion for receiving at least part of a generator system;
- and
- wherein the step of printing the housing includes printing a cooling jacket portion that is a monolithic part of a sidewall of the housing comprising one or more cooling passages.
The method of claim 6, wherein the step of printing the second housing comprises printing another cooling passage that is larger than the one or more cooling passages of the second housing that are part of the cooling jacket of the second housing.
An aircraft engine starting and generating apparatus comprising:
- a three dimensionally printed housing;
- and
- a generator system comprising:
- a main stator located in the housing;
- a main rotor located in a cavity of the main stator;
- an exciter stator located in the housing;
- and
- an exciter rotor located in a cavity of the exciter stator;
- wherein the housing comprises a cooling jacket portion comprising one or more cooling passages that is a monolithic part of a sidewall of the housing.
