scope:
This specification covers the general requirements for aircraft generators and starter-generators for use in 28-volt direct current systems. As generators, both type machines are engine driven. The starter-generators, however, also function as engine starters when energized by electric power.
The generators and starter-generators shall be of the following type and class as specified:
Type I, Blast Cooled - Type I machines of all classes shall be cooled by externally forced air for all rated operating conditions.
Type II, Self Cooled - Type II machines of all classes shall be cooled by internal means and shall require no externally forced air for rated operating conditions.
Type III, Combination Cooled - Type III machines of all classes shall utilize a combination of both Type I and Type II cooling methods to meet overall performance requirements. Type III machines shall be capable of operating self-cooled at rated load and speeds under Class A sea level conditions.
Type IV, Liquid Cooled - Type IV machines shall meet overall performance requirements under the cooling conditions as defined in the detail drawing or specification.
Class A - Machines designed to operate within the temperature-altitude
Class B - Machines designed to operate within the temperature-altitude
Class C - Machines designed to operate within the temperature-altitude
intended Use:
The machines covered by this specification are intended for new and retrofit use as generators or starter-generators in aircraft. As generators, the machines function as a continuous source of... View More
