DETAIL SPECIFICATION
GENERATORS AND STARTER-GENERATORS, ELECTRICAL DIRECT CURRENT, NOMINAL 30 VOLTS,
AIRCRAFT GENERAL SPECIFICATION FOR
This specification is approved for use by all Departments and Agencies of the Department of Defense.
1. SCOPE
1.1 This specification covers the general requirements for aircraft generators and starter-generators for use in
28-volt (V) direct current (DC) systems. As generators, both type machines are engine driven. The starter-
generators, however, also function as engine starters when energized by electric power.
1.2 Classification. The generators and starter-generators will be of the following type and class as specified:
TYPE
STYLE
DESCRIPTION
Type I
Blast Cooled
Cooled by externally forced air for all rated operating conditions
Type II
Self Cooled
Cooled by internal means and will require no externally forced
air for rated operating conditions
Type III
Combination Cooled
Utilizes a combination of both Type I and Type II cooling
methods to meet overall performance requirements. Type III
machines will be capable of operating self-cooled at rated load
and speeds under Class A sea level conditions
Type IV
Liquid Cooled
Meet overall performance requirements under the cooling
conditions as defined in the associated specification sheet
CLASS
DESCRIPTION
Class A
Machines designed to operate within the temperature-altitude range of Figure 1.
Class B
Machines designed to operate within the temperature-altitude range of Figure 2.
Class C
Machines designed to operate within the temperature-altitude range of Figure 3.
